Description

Technical Field

[0001] This utility model relates to the field of fertilizer pretreatment technology, specifically to a pretreatment device for fertilizers used in agricultural production. Background Technology

[0002] Fertilizers are substances that provide one or more essential nutrients for plants, improve soil properties, and enhance soil fertility. They are one of the material foundations of agricultural production. They mainly include ammonium phosphate fertilizers, water-soluble fertilizers containing macronutrients, fertilizers containing micronutrients, bio-fertilizers, organic fertilizers, and multi-dimensional energy-concentrated organic fertilizers. In order to improve fertilizer utilization, nutrient enhancers need to be sprayed on the fertilizers before fertilization to ensure they are fully mixed with the fertilizers and thus promote crop absorption.

[0003] Chinese Patent Publication No. CN219663493U discloses a fertilizer pretreatment device for agricultural production, comprising a frame and a rotating drum. The upper wall of the frame is connected to a tilting plate via a driving component. The driving component allows one end of the tilting plate to tilt. The tilting plate is provided with a pair of limiting grooves. The outer wall of the rotating drum is provided with a pair of annular slide rails that are slidably connected to the limiting grooves. A motor is provided on the tilting plate, and a gear is installed on the drive end of the motor. This utility model relates to the technical field. The device has a compact structure. By setting multiple partitions inside the rotating drum to form a storage trough, the fertilizer can be lifted to a high position in batches and then fall back down when the drum rotates, thus making the fertilizer more dispersed. The liquid supply component can deliver liquids such as synergists to a fixed pipe and spray them out from the spray head, allowing them to fully contact the dispersed fertilizer. This reduces the workload of workers, improves the spraying and mixing efficiency, ensures the subsequent use effect, and brings convenience to people.

[0004] The aforementioned device mixes fertilizer and nutrient enhancer by adding them into the inside of a rotating drum. However, since the fertilizer has a fixed shape and is prone to clumping together, the rotating drum makes it difficult to quickly disperse the clumped fertilizer, resulting in uneven mixing of the fertilizer and nutrient enhancer. Utility Model Content

[0005] To address the aforementioned problems, a pretreatment device for fertilizers in agricultural production is provided. By starting a drive motor, a drive rod rotates, which in turn rotates the drive wheel, rotating block, crushing rod, and stirring rod outside the drive rod. The crushing rod breaks down clumps of fertilizer, dispersing it into fine particles for thorough mixing with nutrient enhancers. Simultaneously, the drive wheel rotates the driven wheel and screw shaft, allowing the nutrient enhancers inside the storage tank to fall into the pretreatment chamber for easy mixing with the fertilizer.

[0006] To address the problems of existing technologies, this utility model provides a pretreatment device for fertilizers used in agricultural production, including a pretreatment box. A protective plate is provided on the top of the pretreatment box, and a drive motor is provided on the top of the protective plate. The output shaft of the drive motor is connected to a drive rod via a coupling. One end of the drive rod extends into the interior of the pretreatment box, and a drive wheel is provided on the outside of the drive rod. A crushing rod for crushing lumpy fertilizers is also provided on the outside of the drive rod, and a stirring rod for mixing fertilizers and nutrient enhancers is also provided on the outside of the drive rod.

[0007] Preferably, the pretreatment box has storage tanks for storing nutrient enhancers on both sides inside. The storage tanks are equipped with a rotating helical shaft inside, and one end of the helical shaft extends to the outside of the pretreatment box and is equipped with a driven wheel that meshes with the driving wheel.

[0008] Preferably, the drive rod is provided with a sealing plate on its exterior for sealing the outlet of the storage tank.

[0009] Preferably, the inner walls on both sides of the pretreatment box are provided with support plates, and the top two sides of the support plates are provided with spring telescopic rods, and the telescopic ends of the spring telescopic rods are provided with filter plates for filtering large-particle fertilizers.

[0010] Preferably, the drive rod is provided with symmetrical rotating blocks on its exterior, the top of the rotating blocks is provided with an abutting rod, and the bottom of the filter plate is provided with an abutting block that abuts against the abutting rod.

[0011] Preferably, the bottom of the pretreatment box is connected to a discharge pipe for discharging materials, and the discharge pipe is equipped with a valve for controlling its closure.

[0012] The advantages of this utility model compared to the prior art are:

[0013] 1. By starting the drive motor, the drive rod is rotated, which in turn drives the drive wheel, rotating block, crushing rod, and stirring rod outside the drive rod to rotate. The crushing rod can crush the fertilizer that has clumped together, dispersing it into fine particles that are easy to mix with the nutrient enhancer. At the same time, the drive wheel drives the driven wheel and the screw shaft to rotate, allowing the nutrient enhancer inside the storage tank to fall into the pretreatment tank for easy mixing with the fertilizer.

[0014] 2. By using the filter plate, larger particles that are difficult to mix can be filtered, while smaller particles will fall to the bottom of the pretreatment box after passing through the filter plate. They will then be mixed by the stirring rod for later use. As the rotating block rotates, it also drives the abutment rod to rotate. The abutment rod reciprocates to squeeze the abutment block at the bottom of the filter plate, so that the filter plate is constantly vibrating under the action of the spring telescopic rod. This prevents larger particles from clogging the filter holes inside the filter plate and affecting the mixing of fertilizer. Attached Figure Description

Detailed Implementation

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 6 As shown, this utility model provides:

[0024] A pretreatment device for fertilizer in agricultural production includes a pretreatment box 1, a protective plate 2 on the top of the pretreatment box 1, a drive motor 3 on the top of the protective plate 2, a drive rod 6 connected to the output shaft of the drive motor 3 via a coupling, one end of the drive rod 6 extending into the interior of the pretreatment box 1, a drive wheel 4 on the outside of the drive rod 6, a crushing rod 7 for crushing lumpy fertilizer on the outside of the drive rod 6, and a stirring rod 12 for mixing fertilizer and nutrient enhancer on the outside of the drive rod 6.

[0025] When fertilizer and nutrient enhancer need to be mixed and pretreated, the fertilizer and nutrient enhancer are first put into the pretreatment tank 1 and storage tank 5 respectively. Then, the drive motor 3 is started to drive the drive rod 6 to rotate, which in turn drives the drive wheel 4, rotating block 15, crushing rod 7 and stirring rod 12 outside the drive rod 6 to rotate. The crushing rod 7 can be used to crush the fertilizer that has clumped together.

[0026] like Figure 3 As shown, storage tanks 5 for storing nutrient enhancers are provided on both sides of the interior of the pretreatment box 1. A spiral shaft 9 is rotatably provided inside the storage tank 5. One end of the spiral shaft 9 extends to the outside of the pretreatment box 1 and is provided with a driven wheel 10 that meshes with the driving wheel 4.

[0027] The driving wheel 4 drives the driven wheel 10 and the screw shaft 9 to rotate, so that the nutrient enhancer inside the storage tank 5 can fall into the pretreatment box 1, which is convenient for mixing with the fertilizer.

[0028] like Figure 3 As shown, a sealing plate 11 for sealing the outlet of the storage tank 5 is provided on the outside of the drive rod 6.

[0029] The sealing plate 11 allows for intermittent feeding of the nutrient enhancer, resulting in a more uniform mixing of fertilizer and nutrient enhancer.

[0030] like Figure 5 As shown, support plates 13 are provided on both inner walls of the pretreatment box 1, and spring telescopic rods 14 are provided on both sides of the top of the support plates 13. The telescopic ends of the spring telescopic rods 14 are provided with filter plates 8 for filtering large-particle fertilizers.

[0031] The filter plate 8 can be used to filter some larger particles that are not easy to mix, while smaller particles will fall to the bottom of the pretreatment box 1 after passing through the filter plate 8 and be mixed by the stirring rod 12 for easy use later.

[0032] like Figure 6 As shown, symmetrical rotating blocks 15 are provided on the outside of the drive rod 6, and an abutting rod 16 is provided on the top of the rotating block 15. An abutting block 17 that abuts against the abutting rod 16 is provided on the bottom of the filter plate 8.

[0033] The rotating block 15 drives the abutment rod 16 to rotate, and the abutment rod 16 reciprocates to press the abutment block 17 at the bottom of the filter plate 8, so that the filter plate 8 can be in a state of vibration under the action of the spring telescopic rod 14, preventing larger particles from clogging the filter holes inside the filter plate 8 and affecting the mixing of fertilizer.

[0034] like Figure 1 As shown, the bottom of the pretreatment box 1 is connected to a discharge pipe 18 for discharging materials, and the discharge pipe 18 is equipped with a valve for controlling its closure.

[0035] The mixed fertilizer can be discharged by controlling the opening and closing of the discharge pipe 18 through the valve.

[0036] Working principle: When fertilizer and nutrient enhancer need to be mixed and pretreated, the fertilizer and nutrient enhancer are first added to the pretreatment tank 1 and storage tank 5 respectively. Then, the drive motor 3 is started to drive the drive rod 6 to rotate, which in turn drives the drive wheel 4, rotating block 15, crushing rod 7 and stirring rod 12 outside the drive rod 6 to rotate. The crushing rod 7 can break up the clumps of fertilizer, dispersing it into fine particles for thorough mixing with the nutrient enhancer. At the same time, the drive wheel 4 drives the driven wheel 10 and the screw shaft 9 to rotate, allowing the nutrient enhancer inside the storage tank 5 to fall into the pretreatment tank 1 for easy mixing with the fertilizer. The nutrient enhancer can be intermittently fed using the sealing plate 11, making the fertilizer and nutrient enhancer mix more evenly. Then, the filter plate 8 can filter out some larger particles that are difficult to mix, while smaller particles will fall to the bottom of the pretreatment box 1 through the filter plate 8 and be mixed by the stirring rod 12 for later use. While the rotating block 15 is rotating, it will also drive the abutment rod 16 to rotate. The abutment rod 16 reciprocates to squeeze the abutment block 17 at the bottom of the filter plate 8, so that the filter plate 8 can be kept in a state of vibration under the action of the spring telescopic rod 14, preventing larger particles from clogging the filter holes inside the filter plate 8 and affecting the mixing of fertilizer.
