Description
Technical Field
[0001] This utility model relates to the field of fertilization equipment technology, specifically a solid fertilizer sprayer. Background Technology
[0002] A solid fertilizer spreader is an agricultural machine specifically designed to spread solid fertilizer evenly on farmland or soil surface. Compared with manual fertilization, a solid fertilizer spreader can quickly complete large-area fertilization work, greatly improving fertilization efficiency and saving manpower and time.
[0003] When using existing solid fertilizer spreaders, the drive unit usually drives the spiral blades to rotate, and then the solid fertilizer falls through the discharge port onto the top of the spreading plate. Then the drive unit drives the spreading plate to rotate through the spreading plate. At this time, the spreading plate will throw out the solid fertilizer and spread it onto the soil surface through the action of centrifugal force.
[0004] In existing solid fertilizer spreaders, solid fertilizer tends to accumulate and stagnate in certain parts of the discharge pipe (such as near the inlet or in certain corners of the conveying trough) during the transport process. This accumulation of solid fertilizer occupies part of the pipe's space, reducing its effective cross-sectional area and slowing down the transport speed. Consequently, it prolongs the time it takes for the solid fertilizer to be transported from the storage tank to the field, reducing the overall efficiency of the fertilization operation. To address this issue, we propose a new solid fertilizer spreader. Utility Model Content

An adjustment groove is provided at the right end of the connecting plate 56. The middle of the upper end of the connecting plate 56 is rotatably connected to the inner wall of the protective cover 53. The conveying mechanism 5 is equipped with a drive bearing. The end of the fixed rod 55 away from the center of the storage box 2 is fixedly connected to the inner ring surface of the drive bearing. The conveying mechanism 5 also includes a connecting rod 57, a bevel gear 58, and an adjusting rod 59.

The two bevel gears 58 are meshed together. The left end of the connecting rod 57 is provided with an adjusting rod 59. The left end of the adjusting rod 59 is located inside the adjusting groove. Through the cooperation between the connecting plate 56 and the adjusting rod 59, it can perform vertical reciprocating motion while the spiral blade 52 is rotating. This can prevent solid fertilizer from stagnating and accumulating, increase the fluidity of solid fertilizer, and solve the problem of affecting fertilization efficiency due to some solid fertilizer accumulating inside the feed pipe 7.
[0024] It also includes a control switch group 3, which is located at the top of the storage box 2. The input terminal of the control switch group 3 is electrically connected to an external power supply and can regulate the electrical components inside the equipment.
[0025] Among them: a motor 6 is provided in the middle of the upper end of the protective cover 53. The lower end of the output shaft of the motor 6 is fixedly connected to the upper end of the mounting cylinder 54. The input end of the motor 6 is electrically connected to the output end of the control switch group 3. The motor 6 starts to run through the control switch group 3. The output shaft of the motor 6 drives the mounting cylinder 54 to rotate. The mounting cylinder 54 will drive the mounting rod 51 to rotate through the fixed rod 55.
[0026] The mounting frame 1 has a connecting frame 8 on its lower left side. The upper right side of the connecting frame 8 is rotatably connected to an output rod 9. A spraying plate 10 is located in the middle of the outer arc surface of the output rod 9. The ends of the four spraying plates 11 near the center of the mounting frame 1 are fixedly connected to the outer arc surface of the output rod 9. A drive motor 12 is located on the lower right side of the connecting frame 8. The upper end of the output shaft of the drive motor 12 is fixedly connected to the lower end of the output rod 9. The input end of the drive motor 12 is electrically connected to the output end of the control switch group 3. By controlling the control switch group 3, the drive motor 12 starts to run. The output shaft of the drive motor 12 drives the output rod 9 to rotate. The output rod 9 then drives the spraying plates 11 to rotate through the spraying plate 10. The spraying plates 11 use centrifugal force to throw out and spread solid fertilizer onto the soil surface.
[0027] Among them, a baffle 13 is provided on the left side of the upper end of the connecting frame 8. The baffle 13 can effectively limit the width of the solid fertilizer scattering and prevent the solid fertilizer from being scattered into areas where fertilization is not required.
[0028] The working principle of the solid fertilizer spreader provided by this utility model is as follows: Before use, connect the connecting frame 8 to the external tractor, then open the box door 4 and pour the solid fertilizer into the storage box 2. After the solid fertilizer is added, close the box door 4 again. During the operation of the solid fertilizer spreader, the motor 6 starts running through the control switch group 3. The output shaft of the motor 6 drives the mounting cylinder 54 to rotate, and the mounting cylinder 54 drives the mounting rod 51 to rotate through the fixed rod 55. The mounting cylinder 54 and the mounting rod... With the central axis of 51 aligned, mounting rod 51 drives spiral blade 52 to rotate. Pushed by spiral blade 52, the solid fertilizer moves downwards through the feed pipe 7 and finally falls onto the upper end of the spreading disc 10 via the discharge port. At this point, the drive motor 12 starts operating via control switch group 3. The output shaft of drive motor 12 drives output rod 9 to rotate, which in turn drives spreading plate 11 to rotate via spreading disc 10. Spreading plate 11 uses centrifugal force to throw and spread the solid fertilizer onto the soil surface. Then, an external tractor drives the solid fertilizer spreader to move, thereby achieving the spreading of solid fertilizer. During the rotation of the mounting rod 54, the mounting rod 54 can drive the connecting rod 57 to rotate through the meshing connection between the bevel gears 58. The connecting rod 57 drives the adjusting rod 59 to rotate. At this time, the left end of the adjusting rod 59 moves in a circle around the connecting rod 57. When the adjusting rod 59 rotates, the left end of the adjusting rod 59 will slide inside the adjusting groove and rotate relative to the adjusting groove, which allows the adjusting rod 59 to drive the connecting rod 57 to rotate. The connecting plate 56 performs a vertical reciprocating motion. The connecting plate 56 can drive the mounting rod 51 to perform a vertical reciprocating motion through the fixed rod 55. The mounting rod 51 will drive the spiral blade 52 to perform a vertical reciprocating motion inside the feed pipe 7. When the spiral blade 7 moves upward, it will generate a pushing force opposite to the normal conveying direction. This reverse pushing force will cause disturbance of the solid fertilizer, causing the originally tightly packed or stationary solid fertilizer to loosen. This disturbance will increase the fluidity of the solid fertilizer, thereby reducing the retention and accumulation of solid fertilizer.
[0029] It is worth noting that the motor 6 disclosed in the above embodiments can be a 5IK200A-AF, the drive motor 12 can be an ECMA-C20604RS, and the control switch group 3 is provided with control buttons corresponding to the motor 6 and the drive motor 12 for controlling their switching.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
