Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a shrub-collecting rake. Background Technology

[0002] Shrubs are low-growing, multi-branched woody plants, typically no more than 5-6 meters tall. They are characterized by stems branching from near the ground, forming a dense, clump-like structure. Common shrub species include Caragana korshinskii and Populus tomentosa. They play an important role in the ecosystem, including providing habitat, preventing soil erosion, and regulating climate.

[0003] Currently, when shrubs grow too much, they can block roads within the ranch. Therefore, people usually use shrub-collecting rakes to clear the shrubs on both sides of the road to ensure unobstructed passage. Shrub-collecting rakes in ranches are usually connected to mechanical equipment such as tractors to clear shrubs over a large area, thereby improving the efficiency of shrub collection.

[0004] Currently, shrub-collecting rakes are generally composed of rake teeth and rake body. Some of the rake teeth and rake body are connected by welding to ensure a stronger connection. However, when a few rake teeth are damaged or broken, it will lead to poor shrub collection. Moreover, it is difficult to replace a few rake teeth, resulting in a waste of resources. Therefore, there is an urgent need for a shrub-collecting rake to solve the above problems. Utility Model Content

[0005] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0006] Specifically, the technical problem to be solved by this utility model is to provide a shrub-collecting rake to solve the problem that the current method of connecting the rake body and the rake teeth by welding is wasteful of resources when replacing damaged rake teeth.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] A shrub-collecting rake includes a rake body with rake teeth evenly spaced on one side. A screw is fixedly connected to one end of each rake tooth. Two sets of positioning holes are provided inside the rake teeth, located near the screw. One end of the screw penetrates the rake body. A connecting plate is provided inside the rake body, with a bolt rotatably connected to the bottom of the connecting plate. The top of the bolt extends to the top of the connecting plate. A positioning rod is also fixedly connected to the bottom of the connecting plate, located to one side of the bolt. The bolt and positioning rod are respectively located inside the two sets of positioning holes and are movably connected to them, forming a perpendicular shape to the rake teeth. A threaded hole is provided inside the rake body at the bottom. One end of the bolt passes through one set of positioning holes, penetrates the rake teeth, and extends to the bottom of the rake body, where it is threadedly connected to the threaded hole.

[0009] As an improved technical solution, the rake body is internally fixedly connected with a first positioning plate and a second positioning plate, which correspond to each other and are arranged at equal intervals, and correspond one-to-one with multiple sets of rake teeth.

[0010] As an improved technical solution, both the first positioning plate and the second positioning plate have arc-shaped grooves on their inner sides, and the two sets of arc-shaped grooves form a circular groove. The screw is located between the two sets of arc-shaped grooves. Both the first positioning plate and the second positioning plate have through holes inside, and the through holes are paired and correspond to each other. When the two sets of through holes coincide with the two sets of positioning holes, the bolt and the positioning rod pass through the first positioning plate, the second positioning plate and the rake teeth through the two sets of through holes and the two sets of positioning holes respectively.

[0011] As an improved technical solution, the rake body has two sets of connecting holes inside, which correspond to each other, and the two sets of connecting holes coincide with two sets of through holes respectively.

[0012] As an improved technical solution, the rake body is internally fixedly connected with limiting strips, the limiting strips are in pairs and correspond to each other, the two sides of the connecting plate are provided with limiting grooves that are adapted to the limiting strips, and the rake body is internally provided with grooves, the grooves being located on one side of the limiting strips.

[0013] As an improved technical solution, one side of the rake body is provided with nuts arranged at equal intervals, and one end of the screw extends to the inside of the rake body and is threadedly connected to the nuts. The nuts correspond one-to-one with multiple sets of screws.

[0014] As an improved technical solution, a spring-shaped ring is fixedly connected between the rake teeth and the screw. The two ends of the spring-shaped ring are fixedly connected to the rake teeth and the screw, respectively. An installation groove is provided on one side of the rake body, and the spring-shaped ring is located inside the installation groove and is movably connected to it.

[0015] As an improved technical solution, a hinge seat is installed at one end of the rake body. The hinge seats are arranged at equal intervals. A hinge rod is movably connected inside the hinge seat. A connecting rod is fixed at the end of the hinge rod away from the hinge seat. A connecting rod is movably connected to the connecting rod. The hinge rods are arranged at equal intervals and correspond one-to-one with the hinge seats. A connecting rod is fixedly connected between multiple sets of hinge rods. Multiple sets of hinge rods are connected through the connecting rod.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are:

[0017] 1. This utility model, through the setting of bolts, positioning rods, threaded holes, positioning holes, screws, and nuts, facilitates the replacement of single or multiple sets of damaged rake teeth, thereby reducing resource waste.

[0018] 2. This utility model, through the setting of bolts, positioning rods, positioning holes and threaded holes, can fix the position of the rake teeth to avoid the rake teeth from shifting, thereby ensuring the efficiency of the rake teeth when collecting shrubs normally. Through the setting of screws and nuts, the ends of the rake teeth can be fixed. In combination with the above-mentioned position fixing structure, the stability and mechanical strength of the rake teeth during installation can be ensured.

[0019] 3. This utility model, through the setting of the spring-shaped ring and the mounting groove, enables the rake teeth to have elasticity, thereby enabling the rake teeth to bounce when encountering hard stones, thus reducing the risk of damage to the rake teeth.

[0020] 4. This utility model, through the arrangement of multiple sets of hinge rods, hinge seats and connecting rods, can make the force points of multiple sets of rake teeth more uniform during operation, so as to avoid the phenomenon that the rake teeth are high on one side and low on the other side during operation, thereby improving the efficiency of the rake teeth during operation.

[0036] like Figures 1 to 8 As shown in the figure, this embodiment provides a shrub collection rake, which includes a rake body 1. Rake teeth 2 are installed on one side of the rake body 1. The rake teeth 2 are arranged at equal intervals. A screw 3 is fixedly connected to one end of the rake teeth 2. Positioning holes 8 are provided inside the rake teeth 2. There are two sets of positioning holes 8. The two sets of positioning holes 8 are located on the side close to the screw 3. One end of the screw 3 passes through the rake body 1.

[0037] The rake body 1 has a connecting plate 9 inside. The bottom of the connecting plate 9 is rotatably connected to a bolt 10. The top of the bolt 10 extends to the top of the connecting plate 9. The bottom of the connecting plate 9 is also fixedly connected to a positioning rod 11, which is located on one side of the bolt 10.

[0038] Bolt 10 and positioning rod 11 are located inside the two sets of positioning holes 8 and are movably connected to them, forming a perpendicular shape with the rake teeth 2. The rake body 1 has a threaded hole 12 inside, which is located at the bottom of the rake body 1. One end of bolt 10 passes through the rake teeth 2 through a set of positioning holes 8 and extends to the bottom of the rake body 1 to be threadedly connected to the threaded hole 12. In this way, the position of the rake teeth 2 can be fixed to prevent them from shifting.

[0039] The rake body 1 is internally fixedly connected with a first positioning plate 4 and a second positioning plate 5. The first positioning plate 4 and the second positioning plate 5 correspond to each other and are arranged at equal intervals. They also correspond one-to-one with multiple sets of rake teeth 2, which facilitates the initial positioning of the rake teeth 2.

[0040] Both the inner sides of the first positioning plate 4 and the second positioning plate 5 are provided with arc-shaped grooves 7. The two sets of arc-shaped grooves 7 form a circular groove. The screw 3 is located between the two sets of arc-shaped grooves 7, which facilitates the positioning of the screw 3.

[0041] Both the first positioning plate 4 and the second positioning plate 5 have through holes 6 inside. The through holes 6 are paired up and correspond to each other. When the two sets of through holes 6 coincide with the two sets of positioning holes 8, the bolt 10 and the positioning rod 11 pass through the first positioning plate 4, the second positioning plate 5 and the rake teeth 2 through the two sets of through holes 6 and the two sets of positioning holes 8 respectively. This makes it easy to fix the position of the rake teeth 2, and thus facilitates the installation or disassembly of the rake teeth 2.

[0042] The rake body 1 has a connecting hole 13 inside. There are two sets of connecting holes 13, which correspond to each other. The two sets of connecting holes 13 coincide with the two sets of through holes 6, so that the bolt 10 and the positioning rod 11 can pass through the rake teeth 2, and the bolt 10 can be threadedly connected to the threaded hole 12.

[0043] The rake body 1 is internally fixedly connected with limit strips 14. The limit strips 14 are in pairs and correspond to each other. The two sides of the connecting plate 9 are provided with limit grooves 15 that are adapted to the limit strips 14, which can make the lifting and lowering of the connecting plate 9 more stable, thereby ensuring the accuracy of the bolts 10 and the positioning rods 11.

[0044] The rake body 1 has a groove 16 inside, which is located on one side of the limiting strip 14 to facilitate the rotation of the bolt 10 and thus prevent the rotation force of the bolt 10 from being blocked by the rake body 1.

[0045] Nuts 17 are arranged at equal intervals on one side of the rake body 1. One end of the screw 3 extends to the inside of the rake body 1 and is threadedly connected to the nut 17. The nut 17 corresponds to multiple sets of screws 3 one by one, which facilitates the locking operation of the screw 3, and in turn facilitates the fixing of the end of the rake teeth 2, so as to enhance the stability and mechanical strength of the rake teeth 2 during installation.

[0046] A spring-shaped ring 18 is fixedly connected between the rake teeth 2 and the screw 3. The two ends of the spring-shaped ring 18 are fixedly connected to the rake teeth 2 and the screw 3, respectively. An installation groove 19 is provided on one side of the rake body 1. The spring-shaped ring 18 is located inside the installation groove 19 and is movably connected to it. The spring-shaped ring 18 can give the rake teeth 2 a little elasticity, so that when the rake teeth 2 encounter hard stones during operation, they can automatically bounce up, thereby reducing the risk of damage to the rake teeth 2. The installation groove 19 can prevent the spring-shaped ring 18 from shifting, thereby preventing the spacing between multiple sets of rake teeth 2 from being inconsistent.

[0047] A hinge seat 20 is installed at one end of the rake body 1. The hinge seats 20 are arranged at equal intervals. A hinge rod 21 is movably connected inside the hinge seat 20. A connecting rod 23 is fixed at the end of the hinge rod 21 away from the hinge seat 20. A connecting rod 24 is movably connected to the connecting rod 23. The equidistant arrangement of the hinge seats 20 can make the force points of the rake body 1 evenly distributed, thereby avoiding the phenomenon of one side of the rake teeth 2 lifting up. The connecting rod 24 is used to connect to the drive equipment.

[0048] The hinge rods 21 are arranged at equal intervals and correspond one-to-one with the hinge seat 20. Multiple sets of hinge rods 21 are fixedly connected by connecting rods 22. The multiple sets of hinge rods 21 are connected by connecting rods 22, which can make the force points of the rake body 1 evenly distributed.

[0049] When one or more sets of rake teeth 2 are damaged and need to be replaced, the corresponding nut 17 can be found and rotated in the opposite direction to separate it from the screw 3. Then, the corresponding bolt 10 can be rotated in the opposite direction to separate it from the threaded hole 12 and pulled out, so that the connecting plate 9 and the positioning rod 11 rise synchronously and separate from the through hole 6 in the second positioning plate 5, the positioning hole 8 in the rake tooth 2, the through hole 6 in the first positioning plate 4 and the connecting hole 13 in sequence. Then, the rake tooth 2 can be directly pulled out of the rake body 1 to complete the disassembly of a single set of rake teeth 2. When installing a new rake tooth 2, the operation is reversed. When replacing other sets of rake teeth 2, the operation is the same.

[0050] When the rake teeth 2 encounter a rock with high hardness, the impact force is transmitted to the spring-shaped ring 18. Since the spring-shaped ring 18 is located in the mounting groove 19, it can be ensured that the spring-shaped ring 18 and the rake teeth 2 will not be misaligned. At the same time, when the spring-shaped ring 18 is subjected to the impact force, it will press tightly against the mounting groove 19 and deform, which will cause the rake teeth 2 to bounce up, thus reducing the risk of damage to the rake teeth 2.

[0051] In addition, by setting up three sets of hinge seats 20 and three sets of hinge rods 21, the force points of the rake body 1 can be evenly distributed and transmitted to the connecting rod 23. Furthermore, by connecting the three sets of hinge rods 21 through the connecting rod 22, the phenomenon of one side of the rake teeth 2 being lower than the other side can be avoided, thereby improving the working efficiency of the rake body 1 and the rake teeth 2.

[0052] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
