Description

Technical Field

[0001] This utility model relates to the field of rotary tiller technology, specifically a rotary tiller equipped with a fertilizer applicator. Background Technology

[0002] A rotary tiller is a type of tillage machinery used in conjunction with a tractor to perform tilling and harrowing operations. It is characterized by its strong soil-breaking ability and ability to flatten the soil surface after tilling. It can also chop up stubble buried below the surface, facilitating seeder operations and providing a good seedbed for later sowing. Furthermore, to increase fertilization efficiency, a fertilization mechanism is installed on the rotary tiller to improve its overall performance.

[0003] In existing technology, traditional rotary tillers mainly focus on loosening and leveling the soil, lacking fertilization capabilities. During operation, these machines can only process the soil and cannot simultaneously apply fertilizer, requiring farmers to invest additional manpower and time in fertilization, increasing labor intensity and operating costs. While existing rotary tillers are equipped with corresponding fertilization mechanisms to effectively improve fertilization efficiency, fertilizer tends to clump over time, and the lack of a crushing mechanism inside the fertilizer tank prevents effective discharge of fertilizer and clogs the rear pipes, thus affecting the effectiveness of the rotary tiller's fertilization mechanism.

[0004] Therefore, a rotary tiller with a matching fertilizer applicator is needed to solve the problem that existing fertilizer applicators do not have a corresponding crushing mechanism in their fertilizer tank, which leads to the fertilizer not being effectively discharged and affects the effectiveness of the fertilizer applicator. Utility Model Content

[0005] The purpose of this invention is to provide a rotary tiller with a matching fertilizer applicator to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotary tiller with a matching fertilizer application mechanism, comprising a rotary tiller body, a fertilizer bin, and a rotary tillage mechanism, wherein a rotating shaft is inserted into the middle of the fertilizer bin, and multiple crushing plates are installed on both the upper and lower sides of the rotating shaft, and multiple placement slots are provided inside the fertilizer bin.

[0007] Preferably, a drive wheel is installed on the outer front part of the rotary tillage mechanism, a driven wheel is installed on the outer front part of the rotating shaft, and a transmission belt is sleeved on the outer side of the driven wheel.

[0008] Preferably, the lower part of the drive belt is sleeved on the outside of the drive wheel, and the drive belt is located on the front side of the rotary tiller body.

[0009] Preferably, the upper and lower crushing plates are provided with grooves on opposite sides of their interiors, and connecting plates are installed on the inner walls of the grooves. A support block is installed on one side of the connecting plate, and multiple elastic elements are installed on the other side. Brushes are installed on opposite sides of the support blocks on both the upper and lower sides. Arc-shaped inclined grooves are provided on the front and rear sides of the bottom of the placement groove.

[0010] Preferably, the adjacent sides of the elastic elements on both the upper and lower sides are installed on the inner wall of the slide groove, and the opposite sides of the support blocks on both the upper and lower sides penetrate the crushing plate.

[0011] Preferably, the bottom of the lower brush is attached to the bottom of the placement groove and to the inner wall of the arc-shaped inclined groove, while the top of the upper brush is attached to the cover plate of the fertilizer box.

[0012] Preferably, the rotating shaft passes through the front side of the fertilizer box and through multiple placement slots in the middle, and the crushing plate is disposed on the inner wall of the placement slots.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The rotary tiller with a matching fertilizer applicator proposed in this utility model uses the cooperation between the drive wheel, driven wheel and transmission belt to drive the rotating shaft to rotate on the inner wall of the fertilizer tank when the rotary tiller is tilling the ground. At the same time, it drives multiple sets of crushing plates to crush the fertilizer blocks in the placement trough, thereby reducing the blockage of the fertilizer tank discharge pipe caused by the accumulation of material blocks. In addition, the linkage method reduces the use of the drive source, lowers the operating cost of the rotary tiller's fertilizer applicator, and improves its practicality and overall use effect.

[0024] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1: Please refer to Figures 1-7 This utility model provides a technical solution: a rotary tiller with a matching fertilizer application mechanism, including a rotary tiller body 1, a fertilizer box 2, and a rotary tillage mechanism 4. The fertilizer box 2 is bolted to the rotary tiller body 1, and its right-side discharge pipe is a flexible hose for easy disassembly. A rotating shaft 3 is inserted into the middle of the fertilizer box 2, and multiple crushing plates 8 are installed on both the upper and lower sides of the rotating shaft 3. Multiple placement slots 9 are opened inside the fertilizer box 2. The rotating shaft 3 passes through the front side of the fertilizer box 2 and passes through the multiple placement slots 9 in the middle, so that when the rotary tillage mechanism 4 rotates, it drives the rotating shaft 3 to rotate synchronously, so as to drive the crushing plates 8 to crush the fertilizer blocks on the inner wall of the placement slots 9. The crushing plates 8 are set on the inner wall of the placement slots 9, so as to facilitate the crushing of the fertilizer blocks on the inner wall of the placement slots 9, thereby improving the use effect of the rotary tiller body 1.

[0026] First, start the rotary tiller body 1, which drives the rotary tillage mechanism 4 to till the ground. At the same time, pour fertilizer into the inner wall of the placement trough 9. While the rotary tiller body 1 is tilling the ground, it drives the rotating shaft 3 to rotate on the inner wall of the fertilizer box 2, which in turn drives the multiple sets of crushing plates 8 on its outer side to crush the fertilizer blocks on the inner wall of the placement trough 9, so as to prevent the fertilizer blocks from blocking the discharge pipe, thereby improving the use effect of the fertilizer application mechanism of the rotary tiller body 1 and reducing the cost of use.

[0027] Example 2: Based on Example 1, in order to achieve synchronous drive of the rotating shaft 3 to drive the crushing plate 8 for crushing, a drive wheel 7 is installed on the outer front part of the rotary tiller mechanism 4, and a driven wheel 5 is installed on the outer front part of the rotating shaft 3. A transmission belt 6 is sleeved on the outer side of the driven wheel 5. The lower part of the transmission belt 6 is sleeved on the outer side of the drive wheel 7. The transmission belt 6 is located on the front side of the rotary tiller body 1, so that the cooperation between the transmission belt 6, the drive wheel 7 and the driven wheel 5 can be used to drive the rotating shaft 3 to rotate synchronously.

[0028] First, start the rotary tiller body 1, which drives the rotary tillage mechanism 4 to till the ground. At the same time, the rotary tillage mechanism 4 drives the drive wheel 7 to rotate, and drives the driven wheel 5 to rotate through the transmission belt 6. This drives the rotating shaft 3 to rotate on the inner wall of the fertilizer box 2, which in turn drives the multiple sets of crushing plates 8 on the outside of it to crush the fertilizer blocks on the inner wall of the placement trough 9, so as to prevent the fertilizer blocks from blocking the discharge pipe. By using the linkage method, the use of the drive source is reduced, thereby improving the use effect of the fertilizer application mechanism of the rotary tiller body 1 and reducing the cost of use.

[0029] Example 3: Based on Example 2, in order to simultaneously move the fertilizer from the arc-shaped inclined chute 10 to the discharge pipe during crushing to assist in feeding, grooves 13 are provided on opposite sides of the interior of the upper and lower crushing plates 8. Connecting plates 15 are installed on the inner walls of the grooves 13, thereby preventing the support blocks 11 from detaching from the crushing plates 8. Support blocks 11 are installed on one side of the connecting plate 15, and multiple elastic elements 14 are installed on the other side. Brushes 12 are installed on opposite sides of the upper and lower support blocks 11. Arc-shaped inclined chute is provided on both the front and rear sides of the bottom of the placement trough 9. 10; The adjacent sides of the upper and lower elastic elements 14 are installed on the inner wall of the chute 13, and the opposite sides of the upper and lower support blocks 11 penetrate the crushing plate 8. Thus, the elastic force of the elastic element 14 is used to push the brush 12 to fit against the bottom wall of the placement trough 9 and to move the fertilizer through the arc-shaped inclined chute 10 to the discharge pipe. The bottom of the lower brush 12 is attached to the bottom of the placement trough 9 and to the inner wall of the arc-shaped inclined chute 10, and the top of the upper brush 12 is attached to the cover plate of the fertilizer box 2. Thus, the setting of the brush 12 can also clean the fertilizer adhering to the side wall of the placement trough 9 to improve the cleaning effect.

[0030] While the crushing plate 8 crushes the fertilizer blocks on the inner wall of the placement trough 9, it drives the brushes 12 on both sides to rotate synchronously. This utilizes the elastic force of the elastic element 14 to push the connecting plate 15 to move backward and drive the support block 11 to extend outward. At the same time, it pushes the brushes 12 to fit against the bottom wall of the placement trough 9, thereby pushing the fertilizer on the inner wall of the placement trough 9 backward. Through the setting of the arc-shaped inclined groove 10, the fertilizer is pushed to the discharge pipe on the right side of the fertilizer box 2 to assist in the discharge. At the same time, it can also clean the side wall of the placement trough 9 and the inner wall of the cover plate of the fertilizer box 2, thereby reducing fertilizer residue and improving the use effect of the fertilization mechanism.

[0031] In actual use, the rotary tiller body 1 is started first, driving the rotary tillage mechanism 4 to till the ground. At the same time, fertilizer is poured into the inner wall of the placement trough 9. At this time, when the rotary tiller body 1 tills the ground, the rotary tillage mechanism 4 drives the drive wheel 7 to rotate, and drives the driven wheel 5 to rotate through the transmission belt 6. This drives the rotating shaft 3 to rotate on the inner wall of the fertilizer box 2, which in turn drives the multiple sets of crushing plates 8 on its outer side to crush the fertilizer blocks on the inner wall of the placement trough 9 to prevent the fertilizer blocks from blocking the discharge pipe. By using the linkage method, the use of the drive source is reduced, thereby improving the use effect of the fertilizer application mechanism of the rotary tiller body 1 and reducing the cost of use.

[0032] While the crushing plate 8 crushes the fertilizer blocks on the inner wall of the placement trough 9, it drives the brushes 12 on both sides to rotate synchronously. This utilizes the elastic force of the elastic element 14 to push the connecting plate 15 to move backward and drive the support block 11 to extend outward. At the same time, it pushes the brushes 12 to fit against the bottom wall of the placement trough 9, thereby pushing the fertilizer on the inner wall of the placement trough 9 backward. Through the setting of the arc-shaped inclined groove 10, the fertilizer is pushed to the discharge pipe on the right side of the fertilizer box 2 to assist in the discharge. At the same time, it can also clean the side wall of the placement trough 9 and the inner wall of the cover plate of the fertilizer box 2, thereby reducing fertilizer residue and improving the use effect of the fertilization mechanism.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
