Description

Technical Field

[0001] This utility model relates to a self-propelled organic fertilizer applicator with a bending and turning function, belonging to the technical field of organic fertilizer applicators. Background Technology

[0002] Currently, there are three main types of attachment methods for fertilizer applicators: towed, suspended, and self-propelled. Towed machines have their own wheels and are pulled by a tractor; suspended machines are directly attached to the tractor's three-point suspension system; and self-propelled machines have their own engine. However, in the hilly areas of Southwest China, farmland is characterized by numerous slopes, ridges, small plots, and irregular shapes. Traditional fertilizer applicators, due to their large overall length and limited turning radius, are difficult to turn around in narrow plots, resulting in poor operational flexibility and severely impacting the efficiency and applicability of fertilization operations. Therefore, there is an urgent need for a fertilizer applicator that can adapt to complex terrain, has a small turning radius, is easy to operate, and is highly stable, in order to improve the level of mechanization in hilly and mountainous agriculture.

[0006] The rear frame unit includes a rear frame, a fertilizer discharge device, a handrail, and rear wheels. The fertilizer discharge device is mounted on the rear frame, the handrail is located on the rear side of the rear frame, and the rear wheels are mounted on both sides of the rear end of the rear frame.

[0007] The front frame has a vertically arranged rotating sleeve at the middle of its rear end, and the rear frame has a vertically arranged pin at the middle of its front end. The pin is rotatably mounted in the rotating sleeve via a bearing.

[0008] In one example, the fertilizer discharge device includes a fertilizer box, a spiral cavity, a discharge hopper, and a spiral auger. The spiral cavity is arranged laterally at the bottom of the fertilizer box, and one end of the spiral cavity extends to the bottom side of the fertilizer box. The discharge hopper is provided at the bottom of the spiral cavity on this side. The spiral auger is rotatably installed in the spiral cavity.

[0009] In one example, an adjustment mechanism is provided at the top of the spiral cavity. The adjustment mechanism includes a baffle, a handle, and a spring. The baffle is telescopically mounted on the top of the spiral cavity. An ear plate is provided on the outer side of the baffle. The threaded post of the handle passes through the ear plate and the side of the fertilizer box. The spring is sleeved on the threaded post. The telescopic position of the baffle is adjusted by the handle to change the size of the opening between the spiral cavity and the fertilizer box.

[0010] In one example, a linkage mechanism is also included, which includes a first sprocket, a second sprocket, a third sprocket, and a chain. The first sprocket is mounted on the axle of the rear wheel, the second sprocket is mounted on the end of the auger that extends out of the spiral cavity, the lower part of the fertilizer box is provided with a stirring shaft, one end of the stirring shaft extends out of the fertilizer box and is provided with a third sprocket, and a chain is installed between the first sprocket, the second sprocket, and the third sprocket.

[0011] In one example, a fixed sleeve is provided on the outer end face of the spiral cavity, the second sprocket is rotatably mounted on the fixed sleeve, and the drive shaft of the spiral auger extends outward beyond the fixed sleeve; a snap-fit ​​mechanism is provided between the second sprocket and the drive shaft.

[0012] In one example, the locking mechanism includes a retaining ring, an operating ring, and an operating lever.

Detailed Implementation

[0038] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0039] Please see Figures 1 to 13 This embodiment describes a self-propelled organic fertilizer applicator with a bending and turning function, comprising a front frame unit and a rear frame unit.

[0040] The front frame unit includes a front frame 11, a gasoline engine 12, a gearbox 13, and front wheels 14. The gasoline engine 12 and the gearbox 13 are both mounted on the front frame 11. The gearbox 13 is located below the motor. A battery 16 is also mounted on the front frame 11. The battery 16 is used to supply power to the gasoline engine 12. The two front wheels 14 are mounted on both sides of the gearbox 13. The gasoline engine 12 drives the two front wheels 14 to rotate through the gearbox 13, thereby providing the driving power for the organic fertilizer applicator.

[0041] The rear frame unit includes a rear frame 21, a fertilizer discharge device 22, a handrail 23, and rear wheels 24. The fertilizer discharge device 22 is mounted on the rear frame 21, the handrail 23 is mounted on the rear side of the rear frame 21, and the two rear wheels 24 are mounted on both sides of the rear end of the rear frame 21, serving as driven wheels.

[0042] A rotating sleeve 15 is vertically mounted at the center of the rear end of the front frame 11, and a pin 25 is vertically mounted at the center of the front end of the rear frame 21. The pin 25 is rotatably mounted inside the rotating sleeve 15 via two bearings 19. A hinge plate 17 is mounted on the upper part of the pin 25 corresponding to the bearings 19, and a nut 18 is mounted on the lower part of the pin 25 corresponding to the bearings 19.

[0043] When a turn is required, the operator manipulates the handle 23 to push the entire rear frame unit (including the fertilizer discharge device 22, handle 23, and rear wheels 24) to the left or right. At this time, the rear frame unit rotates relative to the front frame unit in the horizontal plane, with its front pin 25 as the center. The front wheels 14, driven by the gasoline engine 12, maintain forward movement or provide steering thrust, while the rear wheels 24 follow the passive steering, thus enabling the machine to complete flexible steering with a minimal turning radius. When the machine needs to turn around in an extremely narrow space, the operator first stops the machine's forward movement. The operator then uses the handle 23 to lift the entire rear frame unit off the ground. At this time, the entire weight of the machine is supported by the front wheels 14. While keeping the rear wheels 24 off the ground, the operator pushes the handle 23 laterally in the target direction. At this point, since the rear wheel 24 is off the ground, the rear frame unit can rotate freely 360 degrees in the horizontal plane with the pivot 25 as the center, occupying almost no additional lateral space. After the rear frame unit rotates to the desired direction, the operator slowly lowers the rear frame unit, allowing the rear wheel 24 to re-contact the ground, thus restoring normal driving. This device enables the machine to easily adapt to small, irregular plots of land in hilly and mountainous areas, making operation labor-saving and stable.

[0044] To facilitate fertilization, the fertilizer discharge device 22 includes a fertilizer box 221, a spiral cavity 222, a discharge hopper 223, and a spiral auger 224. The fertilizer box 221 has a box-like structure that is wider at the top and narrower at the bottom. The spiral cavity 222 is horizontally positioned at the bottom of the fertilizer box 221, with one end extending to the bottom side of the fertilizer box 221. The discharge hopper 223 is located at the bottom of the spiral cavity 222 on this side. The spiral auger 224 is rotatably installed inside the spiral cavity 222. The fertilizer in the fertilizer box 221 is conveyed to the discharge hopper 223 and discharged through the rotation of the spiral auger 224. The spiral auger 224 can evenly discharge the fertilizer in the fertilizer box 221, ensuring uniform fertilization.

[0045] For ease of operation, an adjustment mechanism 26 is provided at the top of the spiral cavity 222. The adjustment mechanism 26 includes a baffle 261, a handle 262, and a spring 263. The baffle 261 is telescopically mounted on the top of the spiral cavity 222. An ear plate 264 is provided on the outer side of the baffle 261. The threaded post of the handle 262 passes through the ear plate 264 and the side of the fertilizer box 221. The spring 263 is sleeved on the threaded post. By rotating the handle 262 to change the extension length of the spiral post, the telescopic position of the baffle 261 in the spiral cavity 222 can be changed simultaneously, thereby changing the opening size between the spiral cavity 222 and the fertilizer box 221, and realizing the adjustment of the fertilizer discharge rate.

[0046] For ease of operation, a linkage mechanism 27 is also included, which includes a first sprocket 271, a second sprocket 272, a third sprocket 273, and a chain 274. The first sprocket 271 is mounted on the shaft of the rear wheel 24. One end of the auger 224 extends out of the auger cavity 222 and is fitted with the second sprocket 272. A stirring shaft 225 is mounted on the lower part of the fertilizer tank 221, and one end of the stirring shaft 225 extends out of the fertilizer tank 221 and is fitted with the third sprocket 273. A chain 274 is installed between the first sprocket 271, the second sprocket 272, and the third sprocket 273. Thus, when the rear wheel 24 rotates, it can synchronously drive the rotation of the first sprocket 271, the second sprocket 272, and the third sprocket 273, thereby driving the discharge operation of the auger 224 and the stirring operation of the stirring shaft 225, preventing the organic fertilizer from "bridging" in the fertilizer tank.

[0047] For ease of operation, a fixed sleeve 275 is provided on the outer end face of the spiral cavity 222. The second sprocket 272 is rotatably mounted on the fixed sleeve 275. The drive shaft 276 of the spiral auger 224 extends outward beyond the fixed sleeve 275. A locking mechanism 28 is provided between the second sprocket 272 and the drive shaft 276. The locking mechanism 28 includes a retaining ring 281, an operating ring 282, and an operating lever 283. The outer side of the second sprocket 272 is provided with a retaining groove 284. The drive shaft 276 is provided with a key block 285. The outer side of the retaining ring 281 is rotatably mounted on the operating ring 282. The outer ring surface of the retaining ring 281 is provided with a retaining block 286 corresponding to the retaining groove 284. The inner ring surface of the retaining ring 281 is provided with a keyway 287 corresponding to the key block 285. One end of the operating lever 283 is connected to the operating ring 282, and the other end extends backward to the position of the handrail 23 for easy operation. The operating ring 282 can be controlled by the operating lever 283, which in turn controls the axial movement of the retaining ring 281 on the drive shaft 276. When the retaining block 286 on it is engaged in the retaining groove 284, the second sprocket 272 is connected to the drive shaft 276, so that the second sprocket 272 can drive the drive shaft 276 to rotate. When the retaining block 286 on it is disengaged from the retaining groove 284, the second sprocket 272 rotates while the drive shaft 276 does not rotate, so that it can be used in scenarios where the rear wheel 24 moves without the need for fertilizer discharge operation.

[0048] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
