Tiger-tooth dual-function soil loosening cutter

The technical field of a tiger tooth dual-function soil loosening tool

[0001] The present invention relates to the technical field of agricultural machinery and equipment, and more specifically to a tiger tooth dual-function soil loosening tool.

Background technique

[0002] In agricultural production activities, loosening the hardened soil of the field is an important and heavy-duty operation. The traditional human or animal farming and loosening methods require a lot of time and resources, and the work efficiency is low, which is difficult to satisfy Today's needs. With the continuous advancement of science and technology, agricultural production and gardening industries continue to adopt new mechanical devices for production. For example, the ripper is a kind of agricultural machinery that is widely used by people to loosen soil and turn soil, which can reduce labor. Strength and improve work efficiency are deeply loved by people. For this reason, researchers continue to develop various rippers with different structures.

[0003] The importance of the cutter wheel structure of the ripper as the core of the operations such as soil turning, soil preparation, and hoeing of the ripper is needless to say. However, the cutter wheels of most rippers are relatively loose. For example, the Chinese Utility Model Patent Authorized Announcement No. CN202738389 discloses a cutter wheel structure of a ripper, including a cutter wheel shaft and several sets of blades mounted on the cutter wheel shaft. One end of the cutter wheel shaft is connected with the output end of the power equipment. The blades are single-tooth blades. They are installed on the cutter shaft through the blade limit sleeves in a set of two in a diagonal manner. The blades are assembled in a spiral at a certain angle, and the structure is not compact enough, and the blade arrangement is unreasonable, resulting in different depths of loose soil, and when there are more straws and weeds, the straws and weeds are easily involved and entangled. On the cutter wheel, it seriously affects the operation of the cutter wheel, resulting in a decrease in work efficiency and shortening of equipment life.

Summary of the invention

[0004] The present invention provides a tiger tooth dual-function soil loosening tool to solve the problems of the existing loose soil loosening cutter wheel structure, unreasonable blade arrangement, different loosening depths, poor weeding effect and poor soil loosening efficiency.

[0005] The present invention adopts the following technical solutions:

[0006] A dual-function ripper with tiger teeth, including a rotating shaft, the middle of the rotating shaft is connected to the output end of the power equipment, and a ripper wheel is provided on the left and right sides of the rotating shaft, and the ripper wheel includes a rotating shaft support and A plurality of blade support rods, the center of the shaft support is fixed on the shaft, the blade support rods are spirally arranged on the circumferential surface of the shaft support, and the blades on the left and right ripper wheels The supporting rods cooperate with each other to form a V-shaped arrow arrangement, and a plurality of loosening blades are fixed on each blade supporting rod at intervals.

[0007] Further, the ripper blades are arranged in a triangle shape, and each ripper blade is fixed on the blade support rod obliquely in the same direction.

[0008] Further, the direction of the V-shaped arrow is consistent with the forward direction of the power equipment, and the inclination direction of the ripper blade is consistent with the forward direction of the power equipment. The horizontal inclination angle of the soil loosening blade and the blade support rod is 60-80°.

[0009] Further, the direction of the V-shaped arrow is opposite to the forward direction of the power equipment, and the inclination direction of the ripper blade is opposite to the forward direction of the power equipment. The horizontal inclination angle of the soil loosening blade and the blade support rod is 100-120°.

[0010] Further, the ripper blades on two adjacent blade struts are arranged alternately with each other.

[0011] Further, the rotating shaft bracket includes a plurality of support rings, the support rings are sleeved on the rotating shaft at intervals to support

A plurality of supporting rods for fixed connection with the rotating shaft are arranged in the supporting ring.

[0012] Further, the blade support rod is connected to the support ring by a bolt.

[0013] Further, the power equipment is a walk-behind tractor.

[0014] From the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages:

[OOW] 1. During the operation of the present invention, the output end of the power equipment drives the rotating shaft to rotate, thereby driving the loosening cutter wheel to rotate, and the soil on the farmland is reclaimed and loosened by the loosening blade on the loosening cutter wheel. Since the blade support rods are spirally arranged on the circumference of the shaft support, the loosening blades are fixed on the blade support rods at the same interval and obliquely, so that the loosening blades gradually cut into the soil during the loosening process. Farmland, and a single soil loosening wheel cuts into the farmland at the same time, and the number of loosening blades for loosening the soil is kept at about 1 to 3, which not only reduces the forward resistance of the soil loosening wheel, but also reduces the farmland to the soil loosening knife. The reaction force of the wheel reduces the vibration of the loosening cutter wheel, making the loosening cutter wheel more stable and relaxed when walking, reducing labor intensity, and improving the efficiency of land reclamation and loosening.

[0016] 2. The loosening blades on the two adjacent blade struts are arranged in a staggered arrangement to ensure that every inch of the farmland can be reclaimed by the loosening blade, and the loosening blade is reclaiming and loosening the soil. At the same time, the loosening blades staggered back and forth can crush the soil better to ensure the consistency of the loosening depth and the quality of the loosened soil.

[0017] 3. When the V-shaped arrow direction of the blade support rods on the left and right loosening cutter wheels is consistent with the forward direction of the power equipment, and the inclination direction of the loosening blade is consistent with the direction of the V-shaped arrow, when reclaiming and loosening the soil, The soil loosening blade cuts into the farmland gradually from the middle to the two ends one by one. When the soil loosening blade leaves the farmland, it also gradually leaves from the middle to the two ends. The tilt direction of the soil loosening blade and the forward way of the V-shaped arrow make the farmland clearing and loosening the soil. Faster and more powerful, with strong soil-breaking ability, suitable for reclaiming farmland with hard soil.

[0018] 4. When the V-shaped arrow direction of the blade support rods on the left and right loosening cutter wheels cooperates with each other and the forward direction of the power equipment is opposite, and the inclination direction of the loosening blade is the same as the direction of the V-shaped arrow. The loosening blade is gradually pressed into the farmland from both ends to the middle. If straw or weeds are encountered when the loosening soil is pressed, the loosening blade can dig up the straw and weeds from the farmland and dig up when it leaves the farmland. When the straw and weeds are raised back with the loosening blade, the inclination direction of the loosening blade is opposite to the forward and rotating direction, so the straw and weeds will not be caught and entangled on the loosening wheel. Therefore, it can remove taller juveniles and weeds, and is suitable for reclaiming farmland where juveniles and weeds are luxuriant.

[0019] 5. The rotating shaft bracket is composed of a plurality of supporting rings fixed on the rotating shaft, and the blade support rod is fixedly connected with the supporting ring by bolts. The structure is simple and compact, and the assembly is convenient, firm and reliable. At the same time, the rotating shaft bracket is also suitable for looseness. The space gap of the soil prevents the farmland soil from being crushed and crushed by the soil loosening blade to be crushed and compacted by the rotating shaft support to ensure the softness of the farmland after the loosening of the soil.
