Description

Technical Field

[0001] This utility model belongs to the field of fertilizer spreading technology, specifically relating to a uniform spreader for compound fertilizer spreading. Background Technology

[0002] Compound fertilizers are chemical fertilizers containing two or more of the essential nutrients nitrogen, phosphorus, and potassium. They have advantages such as high nutrient content, few byproducts, and good physical properties. They play a vital role in balanced fertilization, improving fertilizer utilization, and promoting high and stable crop yields. Compound fertilizers can be applied directly by broadcasting or dissolved. When broadcasting, the fertilizer can be spread on the ground first, and then, depending on the specific crop and soil conditions, methods such as tilling, land preparation, watering, or covering with soil should be adopted to maximize fertilizer efficiency and avoid negative impacts on crops or soil. When spreading compound fertilizer, the simple equipment usually consists of a movable cart and a hopper mounted on the cart. A spreading port connected to the hopper is located at the bottom or front of the cart, allowing the compound fertilizer to be spread while the cart is moving. However, in actual use, this equipment cannot spread fertilizer on both sides of the cart simultaneously, resulting in a limited spreading range per trip. Furthermore, the fertilizer spread through the spreading port is too concentrated and not evenly distributed, leading to low overall spreading efficiency and hindering the compound fertilizer from achieving its full effect. Therefore, this equipment needs improvement. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a uniform spreader for compound fertilizer spreading, which can simultaneously spread compound fertilizer evenly on the front and left and right sides of a moving trolley, so as to solve the above problems.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a uniform spreader for compound fertilizer distribution, comprising a mobile trolley and a hopper fixedly mounted on the mobile trolley. The top of the hopper is open, and its bottom is connected to the upper port of a four-way pipe. The upper port of the four-way pipe is equipped with a valve, and the other three lower ports face the front and left and right sides of the mobile trolley, respectively. Screw conveyors are fixedly mounted on the mobile trolleys on the front and left and right sides of the hopper. The feed inlet of the screw conveyor is close to the direction of the hopper, and the feed is discharged at an angle. The pipe is fixedly connected to the lower end of the four-way pipe on the same side. The discharge ports of the three sets of screw conveyors are located on the front and left and right sides of the moving trolley and are rotatably connected to the rotating pipe. The upper side of the rotating pipe is fixedly sleeved with a driven gear. A motor is fixedly installed on the bottom of the casing of the screw conveyor on the side of the driven gear. The output shaft of the motor faces downward and is fixedly sleeved with a driving gear that meshes with the corresponding driven gear. The bottom end of the rotating pipe is detachably connected to the upper end of an inverted Y-shaped three-way pipe. Several material discharge holes are opened at the bottom of the two inclined parts of the three-way pipe.

[0005] Preferably, a support plate is fixedly connected to the lower side of the rotating tube. A through groove is formed on the support plate from top to bottom. A positioning blind hole is formed at the bottom and an internally threaded blind hole is formed at the top of the support plate on the side of the through groove away from the rotating tube. A mounting plate is fixedly connected to the upper side of the tee tube. The top of the tee tube abuts against the bottom of the rotating tube, and the top of the mounting plate abuts against the bottom of the corresponding support plate. A positioning post is fixedly provided on the top of the mounting plate corresponding to the positioning blind hole. The positioning post is inserted into the corresponding positioning blind hole. A rotating shaft is rotatably provided on the top of the mounting plate corresponding to the through groove. A fixing plate is fixedly sleeved on the upper part of the rotating shaft, and a handle is fixedly provided on the top. The rotating shaft, the fixing plate, and the handle all pass through the corresponding through groove, and the bottom surface of the fixing plate is flush with the top surface of the support plate. After the rotating shaft rotates 90 degrees, the fixing plate abuts against the top surface of the corresponding support plate, and an internally threaded through hole is formed at the position corresponding to the internally threaded blind hole. The same wing bolt is screwed onto the internally threaded through hole and the corresponding internally threaded blind hole.

[0006] Preferably, the positioning post is adapted to the corresponding positioning blind hole.

[0007] Preferably, the mobile trolley consists of a base and casters mounted at the four corners of the base.

[0008] Preferably, the mobile trolley is equipped with a vehicle-mounted mobile power supply and a controller, and the screw conveyor and motor are both electrically connected to the vehicle-mounted mobile power supply through the controller.

[0009] Preferably, a handrail is installed on the rear side of the mobile trolley.

[0010] The beneficial effects of this utility model are as follows: When spreading compound fertilizer, the compound fertilizer can be poured into the hopper first, and then the moving trolley can be pushed forward. During the process, the valve is opened and the screw conveyor and motor are run. Through the cooperation of the four-way pipe and the corresponding discharge pipe, the compound fertilizer in the hopper is first diverted to three sets of screw conveyors. Then, under the conveying of each set of screw conveyors, each set of compound fertilizer is transported and unloaded into the rotating pipe. Then, through the rotating pipe, the compound fertilizer falls into the three-way pipe, and finally is discharged onto the ground through the discharge hole on the three-way pipe. In this way, compound fertilizer can be spread simultaneously from the front and left and right sides of the moving trolley, and the single-pass spreading range is wider. At the same time, the operation of the motor, combined with gear transmission, can drive the corresponding rotating pipe and the three-way pipe of the same group to rotate as a whole, so that the compound fertilizer can be more evenly dispersed and spread on the ground, avoiding overly concentrated spreading, further increasing the spreading coverage area, thereby greatly improving the overall spreading efficiency, and making it more conducive to the effectiveness of compound fertilizer, resulting in higher spreading quality and greater practicality.

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0020] like Figures 1 to 7As shown, a compound fertilizer spreader includes a mobile trolley 1 and a hopper 2 fixedly mounted on the mobile trolley 1. The top of the hopper 2 is open, and its bottom is connected to the upper port of a four-way pipe 3. A valve 4 is provided on the upper port of the four-way pipe 3, and the other three lower ports face the front and left / right sides of the mobile trolley 1, respectively. Screw conveyors 5 are fixedly mounted on the mobile trolley 1 on the front and left / right sides of the hopper 2. The feed inlets of the screw conveyors 5 are close to the direction of the hopper 2 and are fixedly connected to the lower ports of the four-way pipe 3 on the same side via inclined discharge pipes 6. The discharge ports of the three sets of screw conveyors 5 are located on the front and left / right sides of the mobile trolley 1, respectively, and are rotatably connected to rotating pipes 7. A driven gear 8 is fixedly sleeved on the upper side of the rotating pipe 7. A motor 9 is fixedly mounted on the bottom of the casing of the screw conveyor 5 on one side of the driven gear 8. The output shaft of the motor 9 faces downward and is fixedly sleeved with a driving gear 10 that meshes with the corresponding driven gear 8. The bottom end of the rotating pipe 7 is detachably connected to the upper end of an inverted Y-shaped tee pipe 11. Several material discharge holes 12 are provided at the bottom of the two inclined parts of the tee pipe 11.

[0021] When spreading compound fertilizer, first pour the compound fertilizer into the hopper 2, then push the moving trolley 1 to move. During the process, open the valve 4 and run the screw conveyor 5 and motor 9. Through the cooperation of the four-way pipe 3 and the corresponding discharge pipe 6, the compound fertilizer in the hopper 2 is first diverted to the three sets of screw conveyors 5. Then, under the conveying of each set of screw conveyors 5, each set of compound fertilizer is conveyed and unloaded into the transfer pipe 7. Then, through the transfer pipe 7, the compound fertilizer falls into the three-way pipe 11. Finally, it is discharged onto the ground through the discharge hole 12 on the three-way pipe 11. In this way, compound fertilizer can be spread from the front and left and right sides of the moving trolley 1 at the same time, and the single-trip spreading range is wider. Simultaneously, the operation of motor 9, in conjunction with gear transmission, drives the corresponding rotating pipe 7 and the three-way pipe 11 in the same group to rotate as a whole. This allows the compound fertilizer to be more evenly dispersed and spread across the ground, avoiding overly concentrated spreading and further increasing the spreading coverage area. This significantly improves the overall spreading efficiency and makes it more effective for the compound fertilizer, resulting in higher spreading quality and greater practicality. The screw conveyor 5 can utilize existing technology; its specific structure and working principle will not be detailed here.

[0022] In this embodiment, a support plate 13 is fixedly connected to the lower side of the rotating tube 7. A through groove 14 is provided on the support plate 13 in a vertically penetrating manner. A positioning blind hole 15 is provided at the bottom of the support plate 13 on the side of the through groove 14 away from the rotating tube 7, and an internal thread blind hole 16 is provided at the top. A mounting plate 17 is fixedly connected to one side of the upper end of the tee pipe 11. The top end of the tee pipe 11 abuts against the bottom end of the rotating pipe 7, and the top of the mounting plate 17 abuts against the bottom of the corresponding support plate 13. A positioning post 18 is fixedly provided on the top of the mounting plate 17 corresponding to the positioning blind hole 15. The positioning post 18 is inserted into the corresponding positioning blind hole 15. A rotating shaft 19 is rotatably provided on the top of the mounting plate 17 corresponding to the through groove 14. A fixing plate 20 is fixedly sleeved on the upper part of the rotating shaft 19, and a handle 21 is fixedly provided on the top end. The rotating shaft 19, the fixing plate 20 and the handle 21 all pass through the corresponding through groove 14, and the bottom surface of the fixing plate 20 is flush with the top surface of the support plate 13. After the rotating shaft 19 rotates 90 degrees, the fixing plate 20 abuts against the top surface of the corresponding support plate 13, and an internal thread through hole 22 is opened at the position corresponding to the internal thread blind hole 16. The same wing bolt 23 is screwed onto the internal thread through hole 22 and the corresponding internal thread blind hole 16.

[0023] In long-term practical use, due to factors such as mud splashing and fertilizer clumping, the T-pipe 11 may experience blockages or damage. When these problems occur, the T-pipe 11 can be quickly disassembled and reassembled to meet the needs of cleaning, maintenance or replacement. Specifically, when disassembling, in the stopped state, first unscrew the wing bolt 23 to release the lock on the fixing plate 20, then control the rotating shaft 19 to rotate 90 degrees through the handle 21 so that the fixing plate 20 is aligned with the corresponding through groove 14. Then, move the T-pipe 11 down until the handle 21 is completely removed from the through groove 14, and the original T-pipe 11 can be disassembled, which facilitates the cleaning and maintenance of the original T-pipe 11. When reinstalling or replacing the tee pipe 11 after maintenance, simply align the tee pipe 11 with the rotating pipe 7 and abut it in place, align the mounting plate 17 with the support plate 13 and abut it in place, and align the positioning pin 18 with the corresponding positioning blind hole 15 and insert it in place. This will achieve the initial positioning and installation of the tee pipe 11. At this time, the rotating shaft 19, the fixing plate 20, and the handle 21 can all pass through the corresponding through groove 14, and the bottom surface of the fixing plate 20 is flush with the top surface of the support plate 13. Then, control the rotating shaft 19 to rotate 90 degrees, so that the fixing plate 20 presses against the top surface of the support plate 13. At this time, the internal thread through hole 22 can be aligned with the corresponding internal thread blind hole 16. Then, tighten the wing bolt 23 to lock the fixing plate 20 in place, thus completing the fixed installation of the tee pipe 11. The installation is stable and does not affect the subsequent synchronous rotation with the corresponding rotating pipe 7. The overall disassembly and assembly are more flexible, convenient, and practical. The wing bolt 23 can be made using existing technology. It is easy to tighten by hand, which can effectively reduce the difficulty of disassembling and assembling the tee pipe and make it more practical.

[0024] In this embodiment, the positioning post 18 is adapted to the corresponding positioning blind hole 15 to ensure that the positioning post 18 is smoothly inserted into place, so as to achieve the positioning and installation of the tee pipe 11.

[0025] In this embodiment, the mobile trolley 1 consists of a base 24 and casters 25 installed at the four corners of the bottom of the base 24 to meet the overall movement needs of the equipment.

[0026] In this embodiment, the mobile trolley 1 is equipped with an on-board mobile power supply 26 and a controller 27. The screw conveyor 5 and the motor 9 are both electrically connected to the on-board mobile power supply 26 via the controller 27, so that the controller 27 can control the operation of the corresponding components and the on-board mobile power supply 26 can provide energy to the corresponding components. The on-board mobile power supply 26 and the controller 27 can both adopt existing technologies, and their specific models can be selected according to the actual situation, without being specifically limited here.

[0027] In this embodiment, a handrail 28 is installed on the rear side of the mobile trolley 1 to facilitate the movement of the equipment.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
