Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and in particular to a multi-scenario fertilizer spreader with a feeding mechanism. Background Art

[0002] The fertilizer spreader is fixed to the rear of the agricultural machinery and is used to spread the materials to the fields. The fertilizer spreader needs to spread a lot of organic fertilizer when working, so it is necessary to replenish fertilizer in the middle of the operation. Since the amount of fertilizer is large and the weight is heavy, a bag of chemical fertilizer weighs 100 pounds, so it is more laborious to pour it upwards manually. In the prior art, there are many devices that can lift and load fertilizers, such as screw conveyors, chain-type lifting, and track-type lifting. However, screw conveyors require at least two people to operate, and the screw conveyor equipment needs to be carried separately, and it is not suitable to be integrated into the fertilizer spreading equipment, and the efficiency of screw conveyors is not very high; chain-type lifting equipment and track-type lifting equipment have various forms, which are often used in garbage collection trucks and can achieve lifting and dumping at the same time. For example, the patent application number "202011628672.9" discloses a material lifting device that can automatically turn over the material.

[0003] During fertilizer spreading, loading is intermittent, and a fertilizer spreader only requires one person to operate the tractor in front. Therefore, an ideal loading mechanism for a fertilizer spreader would require only one person to operate independently. Furthermore, to improve efficiency, fertilizer spreaders load more organic fertilizer, resulting in taller fertilizer bins. This makes manual loading difficult and physically demanding for farmers. Secondly, because the fertilizer spreading mechanism is located at the rear of the spreader and requires a tractor connection at the front, the loading mechanism can only be installed on the side of the spreader. This requires minimizing its size and mass to avoid excessively increasing the width and weight of the spreader on one side. Furthermore, unlike garbage collection vehicles, the fertilizer bin of a fertilizer spreader is V-shaped, with a larger top and smaller bottom. Using existing lifting and turning mechanisms requires separate brackets installed on the vehicle frame and the sides of the fertilizer bin. For these reasons, a fertilizer spreader loading device specifically designed for fertilizer spreaders is needed that can be operated by one person. Summary of the Invention

[0004] In order to solve the deficiencies in the prior art, the present invention provides a fertilizer spreading device with simple loading and better fertilizer spreading effect.

[0005] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0006] A multi-scenario fertilizer spreader with a loading mechanism: comprising a frame, a loading mechanism, and a fertilizer storage box disposed above the frame. The loading mechanism is used to lift and dump fertilizer into the fertilizer storage box.

[0007] The feeding mechanism includes a turning push rod, a lifting push rod, and a connecting rod 1, a connecting rod 2, a hinged part 3, and a hinged part 4 which are hinged in sequence from head to tail. The lower ends of the turning push rod and the lifting push rod are hinged to the vehicle frame or the fertilizer storage box. The connecting rod 2 and the hinged part 3 are hinged to the upper fixed hinge point, and the upper fixed hinge point is fixedly connected to the vehicle frame or the fertilizer storage box.

[0008] The upper end of the turning push rod is hinged to the hinge point of the connecting rod 1 and the connecting rod 2, and the upper end of the lifting push rod is hinged to the middle part of the hinge part 3;

[0009] The hinged member 4 is connected to a fertilizer box hanging frame for hanging a fertilizer transport box.

[0010] In order to better achieve flipping, the hinge hole distance at both ends of the second connecting rod is equal to the hinge hole distance at both ends of the fourth hinge, and the hinge hole distance at both ends of the first connecting rod is equal to the hinge hole distance at both ends of the third hinge.

[0011] Specifically, the fertilizer box hanging frame is parallel to the hinge part four and the connecting rod two. When the feeding mechanism is in the loading state and the lifting state, the fertilizer box hanging frame, the hinge part four and the connecting rod two are all in a vertical state. When the feeding mechanism is in the turning state, the turning push rod and the lifting push rod are both in an extended state.

[0012] In order to facilitate the hanging of the fertilizer transport box, the upper end of the fertilizer transport box hanging frame is provided with an upper crossbeam, and the upper end of the upper crossbeam is provided with a claw for connecting with the fertilizer transport box. A lower guard plate for abutting against the fertilizer transport box is also provided below the fertilizer box hanging frame.

[0013] In order to ensure that the discharge port of the fertilizer transport box can extend into the interior of the fertilizer storage box: the middle part of the hinge part three is bent toward the direction of the connecting rod one. When the feeding mechanism is in the turning state, the upper end of the fertilizer box hanging frame extends to the inside of the upper edge of the fertilizer storage box.

[0014] Furthermore, a feeding mechanism is provided at the bottom of the fertilizer storage box, and a fertilizer spreading plate is provided behind the feeding mechanism. The fertilizer spreading plate is provided with at least three main blades, and a rib is provided on the upper edge of the main blade. A secondary blade is provided below the rib, and the rib and the secondary blade are both arranged on one side of the rotation direction of the main blade.

[0015] In order to control the spreading width: the angle of the auxiliary blades relative to the spreading disc can be adjusted, and the angle of the main blades along the circumference of the spreading disc relative to the diameter of the spreading disc can be adjusted.

[0016] Furthermore, a guard plate is provided on the outer edge of the fertilizer spreading plate. The guard plate includes a fixed guard plate and a telescopic guard plate that can be telescoped relative to the fixed guard plate. The telescopic direction of the telescopic guard plate is along the outer edge of the fertilizer spreading plate.

[0017] The frame is also provided with a transfer case connected to the power output end of the hooking machine. The transfer case is provided with an oil pump and drives the fertilizer spreading disc to rotate through the transmission shaft. The feeding mechanism is driven by a hydraulic motor, and the hydraulic motor is driven to rotate by the hydraulic pressure of the oil pump.

[0018] The beneficial effects achieved by the present invention are as follows: First, the loading process can be easily completed by one person. During loading, the loading device performs the main lifting movement, which consumes physical energy, while the person mainly performs the horizontal shoveling of organic fertilizer, which is relatively energy-saving. Second, the entire loading mechanism is small in size and does not significantly increase the horizontal width of the vehicle body. Third, the structure is relatively simple and not prone to failure, and can be used in high-dust environments.

[0019] The angles of the main blades and the auxiliary blades of the present invention can be adjusted to different spreading widths and forms according to actual needs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0036] like Figures 1 to 5 As shown in the figure, this embodiment discloses a multi-purpose fertilizer spreader with a feeding mechanism. The device comprises a frame 1, a feeding mechanism 4, and a fertilizer storage tank 2 disposed above the frame. The feeding mechanism 4 is used to lift and dump fertilizer into the fertilizer storage tank 2. The feeding mechanism 4 includes a turning push rod 41, a lifting push rod 42, and a connecting rod 1 43, a connecting rod 2 44, a hinge 3 46, and a hinge 4 47, which are hinged end to end. The lower ends of the turning push rod 41 and the lifting push rod 42 are hinged to the frame 1 or the fertilizer storage tank 2. In actual use, the lower ends of the turning push rod 41 and the lifting push rod 42 are preferably hinged to the frame 1. Connecting rod 2 44 and hinge 3 46 are both hinged to an upper fixed hinge point 45, which is fixedly connected to vehicle frame 1 or fertilizer storage box 2. Preferably, upper fixed hinge point 45 is fixedly connected to fertilizer storage box 2. Fertilizer storage box 2 has a V-shaped cross-section, with a larger opening at the top and a smaller opening at the bottom. In this embodiment, the turning push rod 41 and the lifting push rod 42 are preferably hydraulic cylinders.

[0037] The upper end of the material turning push rod 41 is hinged to the hinge points of the connecting rod 1 43 and the connecting rod 2 44 , and the upper end of the lifting push rod 42 is hinged to the middle part of the hinge part 3 46 .

[0038] Hinge member 29 47 connects to the fertilizer box mounting bracket 3, which is used to mount the fertilizer transport box. An upper crossbeam 31 is provided at the upper end of the fertilizer box mounting bracket 3. A claw 311 is provided at the upper end of the upper crossbeam 31 for connecting with the fertilizer transport box 8. The claw 311 is tapered, allowing for easy insertion into the bottom of the upper flange of the fertilizer transport box 8 for mounting. A lower guard plate 32 is also provided below the fertilizer box mounting bracket 3, for abutting against the fertilizer transport box 8.

[0039] Among them, the connecting rod 1 43, the connecting rod 2 44, the hinge 3 46, and the hinge 4 47 can form a parallelogram, that is, the hinge hole spacing at both ends of the connecting rod 2 44 is equal to the hinge hole spacing at both ends of the hinge 4 47, and the hinge hole spacing at both ends of the connecting rod 1 43 is equal to the hinge hole spacing at both ends of the hinge 3 46. Figure 4 and Figure 9 , CDEF in the figure is a parallelogram.

[0040] For the convenience of description, the present embodiment divides the feeding mechanism 4 into three states, namely, the state to be loaded ( Figure 1 、 Figure 2 and Figure 7 Status), Improve Status ( Figure 4 and Figure 8 ) and turning state ( Figure 5 and Figure 9 ), in actual use, the three states also occur in chronological order.

[0041] Therefore, the fertilizer box mounting frame 3 is parallel to the hinge 47 and the second connecting rod 44. When the feeding mechanism 4 is in the loading state and the lifting state, the fertilizer box mounting frame 3, the hinge 47 and the second connecting rod 44 are all in a vertical position, ensuring that the fertilizer transport box can be lifted in a vertical position. When the feeding mechanism 4 is in the feeding state, the feeding push rod 41 and the lifting push rod 42 are both in an extended state.

[0042] To ensure that the upper edge of the fertilizer transport box 8 can be tilted into the interior of the fertilizer storage box after being lifted, the middle portion of the hinge member 3 46 is bent toward the connecting rod 1 43. This has the advantage that the bent portion can match the upper edge of the fertilizer storage box. When the feeding mechanism 4 is in the feeding state, the upper end of the fertilizer box hanging frame 3 extends into the interior of the upper edge of the fertilizer storage box 2.

[0043] Combine Figure 2 and Figure 6The fertilizer storage box 2 also has a feed mechanism 6 at its bottom. Behind this mechanism is a fertilizer spreader 5, typically with a high center and low outer edges. The spreader 5 has at least three main blades 51. Each main blade 51 has a rib 511 at its top edge, and auxiliary blades 512 below it. Both the rib 511 and the auxiliary blades 512 are located on the side of the main blades 51 that rotates, that is, the side on which the main blades 51 propel the fertilizer. There are typically three auxiliary blades 512, which guide the fertilizer ejected by the centrifuge. The angle of the auxiliary blades 512 relative to the spreader 5 is adjustable. The auxiliary blade 512 is connected to the main blade 51 at one end away from the center of the fertilizer spreading disc 5 by screws or rivets, and this connection point serves as a hinge point. There is a fan-shaped through hole 513 on the side of the main blade 51 close to the rotation center. The other end of the auxiliary blade 512 is connected to the fan-shaped through hole 513. The sliding of the connecting screw inside the fan-shaped through hole 513 enables the adjustment of the angle of the auxiliary blade 512 relative to the fertilizer spreading disc 5. The distance between adjacent auxiliary blades 512 increases from the center to the outer edge of the fertilizer spreading disc 5. The advantage of this is that the fertilizer is guided by the auxiliary blades 512 to improve the uniformity of fertilizer spreading and the coverage area. Figure 11 As shown, the conveying mechanism 6 includes a chain 61, a base plate 62, and a scraper 63. The base plate 62 is located between two parallel chains 61, and the scraper 63 is mounted on the two chains. The chains 61 drive the scraper 63 to move relative to the base plate 62. The base plate 62 is located at the bottom of the fertilizer storage box 2. Fertilizer poured into the fertilizer storage box 2 falls on the upper surface of the base plate 62. The chain 61 drives the scraper 63 to scrape the fertilizer into the working range of the fertilizer spreading pan 5.

[0044] Furthermore, the angle of the main blade 51 along the circumference of the fertilizer spreading disc 5 relative to the diameter of the fertilizer spreading disc 5 can be adjusted, as shown in FIG. Figure 6 As shown, there are multiple groups of main blade mounting holes 52 on the fertilizer spreading disc 5, and the multiple groups of main blade mounting holes 52 are distributed at different angles along the direction of the fertilizer spreading disc 5. Figure 6 The line Q in the figure represents the diameter of the spreading disc 5. Figure 6 and Figure 12 The angle P represents the angle of the main blade 51 relative to the diameter of the spreading disc 5 within the plane of the spreading disc 5. The main blade 51 can be adjusted relative to the diameter of the spreading disc 5 by installing the main blade mounting holes 52 at different positions. The purpose of such adjustment is to control the spreading range of the fertilizer in accordance with the rotation speed of the spreading disc 5.

[0045] There are two fertilizer spreading discs 5 in this embodiment. The two fertilizer spreading discs 5 are arranged side by side on both sides of the discharge port of the feeding mechanism 6. The rotation directions of the two fertilizer spreading discs 5 are opposite. Figure 6 The bold arrow in FIG. 1 indicates that the fertilizer is thrown outward from the middle direction of the two spreading discs 5.

[0046] It can be seen from the above description that the angle of the main blade 51 and the angle of the auxiliary blade 512 are both adjustable. The two blades are used in conjunction with each other to control the spreading width of the fertilizer. Figure 2 The P1 and P2 areas in the diagram represent the spreading ranges of the two fertilizer spreading discs 5, respectively. The angle of the auxiliary blade 512 determines the elevation angle of the fertilizer when it leaves the fertilizer spreading disc 5 relative to the horizontal plane. Adjusting the appropriate elevation angle can increase the fertilizer distribution area on the ground. The angle of the main blade 51 determines the initial velocity direction of the fertilizer when it leaves the fertilizer spreading disc 5. Figure 6 As shown, within a certain range, Figure 6 When the angle P in the middle is reduced, the rotation angle of the fertilizer from entering the working area of ​​the fertilizer spreading disc 5 to leaving the fertilizer spreading disc 5 is relatively large, and vice versa. Figure 6 As angle P increases, the rotation angle of fertilizer from entering the working area of ​​the spreader 5 to exiting it becomes relatively small. The angle of the main blade 51 and the speed of the spreader 5 effectively control the fertilizer spread width. This, combined with the angle of the secondary blade 512, further improves uniformity. Furthermore, the spread widths corresponding to the two main blades 51 (areas P1 and P2) can be adjusted independently, accommodating single-sided sweeping of the field.

[0047] like Figure 10 As shown: The power system of this embodiment is as follows. The frame 1 is also equipped with a transfer case 11 connected to the power output end of the hitch. The transfer case 11 is equipped with an oil pump 12, which drives the fertilizer spreader 5 to rotate via the transmission shaft 7. The feeding mechanism 6 is driven by a hydraulic motor 9, which is hydraulically driven by the oil pump 12. At the same time, the oil pump 12 can also drive the turning push rod 41 and the lifting push rod 42 to perform telescopic movement. The specific control device and principle are related to the existing technology and will not be repeated in this embodiment.

[0048] Combine Figures 7 to 9 As shown: when the fertilizer spreader is in the normal fertilizer spreading state, the feeding mechanism 4 is retracted under the side of the fertilizer storage box 2. Since the cross-section of the fertilizer storage box 2 is a V-shaped structure, the feeding mechanism 4 hardly increases the width of the fertilizer spreader, and the fertilizer box mounting frame 3 is also in a vertical state. Therefore, the increase in the vehicle width is small and can usually be controlled at about 10 inches.

[0049] When it is necessary to add fertilizer to the fertilizer storage box 2, it is only necessary to move the fertilizer transport box 8 to the side of the fertilizer box hanging frame 3 and insert the claw 311 into the bottom of the upper flange of the fertilizer transport box 8. By controlling the extension of the lifting push rod 42, the fertilizer box hanging frame 3 can be moved upward in a vertical state. When the fertilizer transport box 8 moves to a certain height above the upper edge of the fertilizer storage box 2, that is, Figure 8state, and then operate the material turning push rod 41 to extend, driving the above-mentioned parallelogram CDEF to move. During this process, point F rotates upward with point C as the center to a height higher than point C, so that the fertilizer inside the fertilizer transport box 8 can be dumped into the inside of the fertilizer storage box 2.

[0050] like Figure 11 and Figure 12 As shown, two fertilizer spreading discs 5 are arranged side by side on either side of the discharge port of the feeding mechanism 6. Guards are also provided on the outer edges of the fertilizer spreading discs 5 to prevent fertilizer from spilling outside the discs 5 and to guide the fertilizer. These guards include a fixed guard 53 and a telescopic guard 54 that can extend relative to the fixed guard 53. The telescopic guard 54 extends along the outer edge of the fertilizer spreading disc 5. The telescopic guard 54 is rotatable relative to the fixed guard 53 to adjust the fertilizer outlet and spreading range. Figure 13 and Figure 14 This is an example of adjusting the spreading width and range by controlling the opening size of the telescopic guard plate 54. In actual application, the fully open state of the guard plate is the normal working state suitable for large fields. Closing some guard plates can reduce the size and convert the centrifugal fertilizer spreader into a side-throwing fertilizer spreader. By adjusting the speed, row spreading ( Figure 14 ), or side-throwing, this mode is suitable for orchards and facility agriculture.

[0051] Compared to the prior art, this embodiment has the following advantages: First, the loading process can be easily completed by one person. During loading, the loading device performs the main lifting movement, and the person mainly performs the horizontal shoveling of organic fertilizer (relatively less physically demanding). Second, the entire loading mechanism 4 is small in size and does not significantly increase the lateral width of the vehicle body. Third, the structure is relatively simple and not prone to failure, and can be used in high-dust environments.

[0052] The angles of the main blades 51 and the auxiliary blades 512 of the present invention can be adjusted to different spreading widths and forms according to actual needs.

[0053] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
