Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer processing technology, and in particular to a compound fertilizer mixing device. Background Technology

[0002] With the development of modern agriculture, higher requirements have been placed on the quality and production efficiency of compound fertilizers. Different crops and soils have different requirements for compound fertilizer formulations, involving the precise proportioning and uniform mixing of various raw materials. Therefore, efficient compound fertilizer mixing equipment is needed.

[0003] In existing technologies, conventional compound fertilizer mixing devices only have a single blade for mixing. The position of this single blade is fixed, and it only mixes in one position during operation. This results in a small contact area with the compound fertilizer, leading to uneven mixing, long mixing time, and the need for multiple mixing operations. Consequently, the quality of the compound fertilizer may not meet the standards, and it may not have the desired effect on crops. This also increases the workload and time cost. Therefore, it is necessary to improve the compound fertilizer mixing device to solve the above problems. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figures 1-6This utility model provides an embodiment: a mixing device for compound fertilizer, including a housing 1 and a sealing cover 4, and also including a gear protection cover 311 and a material pouring mechanism. The sealing cover 4 is disposed on the housing 1, and the gear protection cover 311 is fixedly connected to the housing 1. An inner cylinder 310 is rotatably connected inside the housing 1. A main shaft 35 is rotatably connected to the gear protection cover 311, and the main shaft 35 is rotatably connected to the inner cylinder 310. A blade 39 for mixing compound fertilizer is rotatably connected to the inner cylinder 310. A retainer 42 is fixedly connected to the sealing cover 4, and a handle 41 is fixedly connected to the retainer 42. The blade 39 and the inner cylinder 310 play the role of mixing compound fertilizer. The blade 39 and the inner cylinder 310 rotate together to make the compound fertilizer more evenly mixed. When the blade 39 and the inner cylinder 310 are mixing compound fertilizer, the sealing cover 4 prevents the compound fertilizer from spilling out, and the gear protection cover 311 protects the internal gear set and prevents it from being worn due to direct contact with the outside.

[0021] Please see Figures 1-6 In this embodiment, a motor 31 is fixedly connected to the housing 1, and a drive wheel 32 is fixedly connected to the output end of the motor 31. A driven wheel 34 is fixedly connected to the main shaft 35, and a belt 33 drives the drive wheel 32 and the driven wheel 34. A first gear 36 is fixedly connected to the main shaft 35, and a second gear 37 meshes with the first gear 36. The second gear 37 is fixedly connected to the blade 39, and an internal gear 38 meshes with the second gear 37. The internal gear 38 is fixedly connected to the inner cylinder 310. The belt 33 serves to transmit power and protect the entire machine. When there are hard foreign objects in the compound fertilizer, the blade 39 gets stuck with the foreign objects, and the belt 33 can interrupt the power transmission by slipping or breaking. The motor 31 is fixedly connected to the housing 1, and the motor 31 can rotate with the housing 1 to prevent power loss due to the twisting of the belt 33 during power transmission. The second gear 37 meshes with the inner gear 38, enabling the planetary rotation of the second gear 37. Three blades 39 are provided, symmetrically distributed in a circular array on the inner cylinder 310, and each of the three blades 39 is fixedly connected to the second gear 37. The three blades 39 and the inner cylinder 310 rotate together, making the compound fertilizer more thoroughly and evenly mixed. Several protruding strips are provided inside the inner cylinder 310, evenly distributed in a circular array. The protruding strips provide sufficient friction for the compound fertilizer when it rolls in the inner cylinder 310. The shell 1 has a limiting groove at the corresponding position of the inner cylinder 310, and the inner cylinder 310 rotates inside the limiting groove. The limiting groove limits the inner cylinder 310, supports the rotation of the inner cylinder 310 inside the shell 1, and positions the inner cylinder 310 to prevent it from shifting and shaking.

[0022] Please see Figure 1In this embodiment, the pouring mechanism includes a base 21, which is rotatably connected to the housing 1. A first rotating shaft 22 is fixedly connected to the base 21, and a first rotating block 23 is rotatably connected to the first rotating shaft 22. A second rotating shaft 26 is fixedly connected to the housing 1, and a second rotating block 25 is rotatably connected to the second rotating shaft 26. A hydraulic telescopic rod 24 is fixed between the first rotating block 23 and the second rotating block 25. When there is too much compound fertilizer in the inner cylinder 310, it is difficult to pour out the compound fertilizer by manpower alone. Therefore, a pouring mechanism is needed to replace manpower. The pouring mechanism is implemented by hydraulic transmission. By extending and retracting the hydraulic rod, the opening angle of the inner cylinder 310 can be adjusted within a certain range.

[0023] When mixing compound fertilizer, use handle 41 to remove the sealing cap 4, raise the opening of the inner cylinder 310 using the hydraulic telescopic rod 24, pour the compound fertilizer into the inner cylinder 310, replace the sealing cap 4, start the motor 31, the motor 31 transmits power to the drive wheel 32, the drive wheel 32 transmits power to the driven wheel 34 via belt 33, the driven wheel 34 drives the main shaft 35 to rotate, the main shaft 35 drives the first gear 36 to rotate, the first gear 36 transmits power to the second gear 37, the second gear 37 transmits power to the blades 39 to make them rotate around the center of the inner cylinder 310, the blades 39 transmit force to the inner cylinder 310 to make it rotate, and the compound fertilizer is mixed under the joint drive of the inner cylinder 310 and the blades 39. When the compound fertilizer is fully mixed, remove the sealing cap 4, use the hydraulic telescopic rod 24 to turn the opening of the inner cylinder 310 downwards, and the compound fertilizer is poured out under gravity. Finally, turn off the motor 31.

[0024] Through the above steps, the motor 31 drives the blades 39 and the inner cylinder 310 to rotate, so that the compound fertilizer is stirred by multiple blades 39 and the inner cylinder 310. This solves the problem that a single blade 39 is fixed in position and will only be in one position to stir during operation, resulting in a small contact area with the compound fertilizer. This leads to uneven stirring, long stirring time, and the need for multiple stirrings, which can cause the compound fertilizer to fail to meet the quality standards and not achieve the desired effect on crops, thus increasing the workload and time cost.
