[0002] The compound fertilizer is a kind of high-efficiency, convenient agricultural fertilizer, and plays an important role in improving crop yield and quality. The compound fertilizer needs batching equipment in the production process. The current batching equipment is batched by auger conveying. When the material is given, the auger conveying cannot stop immediately, and the material will continue to flow for a period of time, resulting in that the actual batching amount exceeds the set value, thereby affecting the accuracy of batching. At present, the feeding is ended in advance according to the conveying amount of the auger, but the advance time setting is not easy to control. If the time of ending feeding in advance is set too early, the material conveying amount will be insufficient, so that the batching result is lower than the preset value. On the contrary, if it is set too late, the material conveying amount will be excessive, and the batching result will be higher than the preset value. These two cases will lead to inaccurate batching and affect product quality. SUMMARY

Specific implementation

[0023] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, and those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0024] Any element quantity in the drawings is used for example but not limitation, and any naming is only used for distinction, without any limiting meaning.

[0025] The principle and spirit of the utility model will be explained in detail below by referring to several representative embodiments of the utility model.

[0026] The embodiments of the composite fertilizer accurate batching equipment provided by the utility model:

[0027] As shown in the figure, Figures 1 to 4

[0028] It comprises a weighing box body 1, the bottom surface of the weighing box body 1 is provided with a weighing plate 11, the weighing box body 1 is slidably arranged on a loading platform 2, the loading platform 2 is provided with a telescopic mechanism 3 for driving the weighing box body 1 to slide left and right, one end of the weighing box body 1 is provided with a feed pipe 12, a material conveying pipe 4 is slidably arranged in the feed pipe 12, the end of the material conveying pipe 4 away from the weighing box body 1 extends out of the feed pipe 12, and a conveying auger is arranged in the material conveying pipe 4.

[0029] The outer wall of the material conveying pipe 4 is attached to the inner wall of the feed pipe 12, and the feed pipe 12 can slide left and right relative to the material conveying pipe 4.

[0030] ​The material is conveyed into the weighing box 1 for batching and weighing by the conveying auger. When the batching reaches the required weight as determined by the weighing plate 11, the conveying auger is stopped. Since the conveying auger cannot stop immediately, the weighing box 1 can be moved away from the material conveying pipe 4 by the telescopic mechanism 3. The relative extension between the feeding pipe 12 and the material conveying pipe 4 forms a temporary storage area for the material, improving the accuracy of batching and reducing the complexity and error rate of manual operation.

[0031] In this embodiment, the weighing box 1 is provided with a connecting lug 14 on the side of the feeding pipe 12. The connecting lug 14 is transversely penetrated by a connecting rod 15. The telescopic mechanism 3 is distributed on both sides of the weighing box 1, and the telescopic rods of the two telescopic mechanisms 3 are connected to the two ends of the connecting rod 15.

[0032] The telescopic rods of the two telescopic mechanisms 3 are connected together by the connecting rod 15, forming a stable support structure. This structure makes the weighing box 1 more stable when moving, reducing the possibility of shaking and deviation. Specifically, the telescopic mechanism in this embodiment is a pneumatic cylinder.

[0033] The carrier 2 is provided with a guide assembly 21 distributed on both sides of the weighing box 1.

[0034] Specifically, the guide assembly 21 includes a shaft 211 fixedly arranged on the carrier 2 and a guide wheel 212 rotatably arranged at the top end of the shaft 211. The guide wheel 212 abuts against the side surface of the weighing box 1.

[0035] The guide wheel 212 abuts against the side surface of the weighing box 1, providing stable guidance for the movement of the weighing box 1 on the carrier 2. This helps to reduce the shaking and deviation of the weighing box 1 during movement. The guide wheel 212 is designed to rotate. When the weighing box 1 moves on the carrier 2, the guide wheel 212 will rotate accordingly, thereby reducing direct contact and friction with the side surface of the weighing box 1. This helps to reduce the degree of wear of the equipment and prolong the service life.

[0036] In this embodiment, the bottom surface of the weighing box 1 is provided with a discharge port 13 distributed on one side of the weighing plate 11. The bottom of the weighing box 1 is provided with a discharge hopper 5, which is in communication with the feeding port of the mixing tank through a pipeline.

[0037] During actual use, when the required material reaches the weight as detected by the weighing plate 11, the conveying is stopped, and the quantified material on the weighing plate 11 is discharged from the discharge port 13 and enters the mixing tank through the discharge hopper 5.

[0038] The material frame 16 is provided with a pull rod 162 on the side away from the feeding pipe 12, and the pull rod 162 is connected with the driving end of the telescopic member 17 after sliding through the side wall of the weighing box body 1.

[0039] The material frame 16 is provided with a pull rod 162 on the side away from the feeding pipe 12, and the pull rod 162 is connected with the driving end of the telescopic member 17 after sliding through the side wall of the weighing box body 1.

[0040] The telescopic member 17 is a gas cylinder, and the telescopic rod of the gas cylinder drives the pull rod 162 to move, thereby driving the material frame 16 to move.

[0041] In specific use, in the initial state, when the material needs to be fed to the weighing plate 11, the material frame 16 is on the weighing plate, and the discharge opening of the feeding pipe 12 corresponds to the upper side of the material frame 16, so as to make the material fall in the central area of the weighing plate 11 as much as possible. The design of the material frame 16 makes the material more evenly distributed on the weighing plate 11, thereby improving the accuracy of weighing. When the material falls into the material frame 16 through the feeding pipe 12, the material frame 16 can receive the material and make it dispersed in the central area of the weighing plate, thereby avoiding the weighing error caused by the accumulation of the material on one side or corner.

[0042] When the weighing is completed, the material frame 16 is pulled by the telescopic member 17, so that the material frame 16 moves with the material. When the material frame 16 is above the discharge opening 13, the material is unloaded from the discharge opening 13, thereby realizing automatic unloading.

[0043] The bottom surface of the material frame 16 and the upper surface of the weighing plate 11 are provided with a gap, which can avoid the contact between the material frame 16 and the weighing plate 11 to affect the weighing, and ensure that the material on the material frame 16 is completely transferred when the material frame 16 moves.

[0044] Specifically, the front and rear sides of the material frame 16 are provided with sliding blocks 161, the inner wall of the weighing box body 1 is provided with U-shaped guide grooves 18 corresponding to the sliding blocks 161, and the free ends of the sliding blocks 161 are slidingly provided in the U-shaped guide grooves 18. Through the cooperation of the sliding blocks 161 and the U-shaped guide grooves 18, the material frame 16 is guided to move, and the vertical support of the material frame 16 is realized.

[0045] The composite fertilizer accurate batching equipment in the embodiment is used in the specific use, the initial state is that the weighing box 1 is at the left side, and the right end of the material conveying pipe 4 is in the right end in the feeding pipe 12, in addition, the material frame 16 is at the middle position on the weighing plate 11, then the feeding is started through the material conveying pipe 4, and the material is gradually accumulated in the material frame 16 on the weighing plate 11.When the feeding meets the batching requirement, the material conveying is stopped, and the weighing box 1 is moved to the right side, so that the relative length between the material conveying pipe 4 and the feeding pipe 12 is extended, and the material temporary storage area is formed, in addition, the material frame 16 is moved to the right side, which assists in transferring the material to the discharging port 13, so that the material is discharged from the discharging port 13.

[0046] According to the above description of the present specification, those skilled in the art can also understand that the terms used, such as "upper", "lower", "front", "rear", "left", "right", "width", "horizontal", "top", "bottom", "inner", "outer" and the like, which indicate the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings of the present specification, and are only for the purpose of facilitating the description of the scheme of the present application and simplifying the description, and are not explicitly or implicitly indicated or implied that the devices or elements involved must have the described specific orientation, be constructed and operated in a specific orientation, therefore the above orientation or positional relationship terms cannot be understood or interpreted as a limitation on the scheme of the present application.

[0047] In addition, in the description of the present specification, the meaning of "a plurality of" is at least two, such as two, three or more, etc., unless otherwise explicitly and specifically limited.
