Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer technology, specifically to a compound fertilizer anti-caking device. Background Technology

[0002] Compound fertilizers have advantages such as high nutrient content, few by-products, and good physical properties. They play a very important role in balanced fertilization, improving fertilizer utilization, and promoting high and stable crop yields. However, they also have some disadvantages. For example, their nutrient ratio is always fixed, while the types, quantities, and ratios of nutrients required by different soils and crops vary. Therefore, it is best to conduct soil testing before use to understand the texture and nutrient status of the field soil. In addition, it is also important to pay attention to using them in combination with single-component fertilizers to achieve better results.

[0003] According to the search, CN222535092U discloses a compound fertilizer anti-caking device, which includes a connecting plate, a cylinder is fixedly embedded on the upper surface of the connecting plate, a sluice plate is fixedly connected to the inner wall of the cylinder, and two sets of support rods are fixedly connected to the bottom surface of the connecting plate, with a base plate fixedly connected to the bottom ends of the two sets of support rods. The aforementioned device, equipped with a motor, a drive gear, a secondary drive gear, a crushing plate, and a rotating plate, utilizes the cooperation of the motor and the drive gear to facilitate the secondary drive gear's rotation, which in turn drives the connecting rod to rotate within the bearing. The rotation of the connecting rod then facilitates the mixing of the compound fertilizer by the crushing plate and the rotating plate, and also allows the compound fertilizer to collide with the baffle for crushing. The crushed compound fertilizer then easily falls through a perforated plate into the collection box. This crushing method is simple to operate and prevents blockages during later conveying, while also accelerating the processing speed of the compound fertilizer and being beneficial for current use. However, in actual use, relying solely on the collision between the crushing plate and the baffle has limited effectiveness in crushing high-humidity or high-viscosity compound fertilizers. When the crushing effect is limited, if the perforation diameter of the perforated plate is larger than the minimum size of uncrushed clumps, some insufficiently dispersed clumps will leak out directly, requiring secondary processing and increasing production costs. Conversely, if the perforation diameter is too small, although it can intercept clumps, it is easily blocked by normal particles or powder, leading to decreased discharge efficiency and requiring frequent shutdowns for cleaning.

[0004] Therefore, it is of great importance to design a compound fertilizer anti-caking device to solve the above-mentioned defects. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model designs a compound fertilizer anti-caking device, which aims to solve the technical problem of limited crushing effect under existing technologies.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A compound fertilizer anti-caking device includes a frame, a crushing cylinder is fixedly installed at the rear end of the top of the frame, a collecting hopper is fixedly connected to the bottom end inside the crushing cylinder, a filter cylinder is installed on the inner side of the front end of the frame, a guide hopper is fixedly installed at the bottom end of the collecting hopper and the bottom end of the guide hopper extends to the inner side of the filter cylinder, and a discharge hopper is fixedly installed on the inner side of the frame and below the filter cylinder. Support frames are fixedly installed on the inner side of the frame and at both the front and rear ends of the filter cartridge. Rollers are rotatably connected to both the left and right ends of the support frames. Guide rails are fixedly connected to the front and rear ends of the filter cartridge at positions corresponding to the rollers. A first motor is fixedly installed on the inner side of the rear end of the frame. A drive shaft is fixedly installed on the drive end of the first motor. A drive sprocket is fixedly installed at the front end of the drive shaft. A transmission sprocket is fixedly installed at the rear end of the filter cartridge at a position corresponding to the drive sprocket. The transmission sprocket is connected to the drive sprocket via a chain.

[0007] As a preferred embodiment of this utility model, the bottom of the first motor is fixedly connected to the frame via a mounting base, and the front end of the drive shaft is rotatably connected to the frame via a bearing seat.

[0008] As a preferred embodiment of this utility model, a feed pipe is fixedly connected to one end of the top of the crushing cylinder, and a conical feed hopper is fixedly connected to the top end of the feed pipe.

[0009] As a preferred embodiment of this utility model, a second motor is fixedly installed at the center of the top of the crushing cylinder, a rotating shaft is fixedly installed at the drive end of the second motor, multiple sets of crushing shafts are fixedly connected to the outer side of the rotating shaft, and multiple sets of collision shafts are fixedly connected to the inner side wall of the crushing cylinder.

[0010] As a preferred embodiment of this utility model, a filter plate is fixedly installed at the connection between the inside of the crushing cylinder and the collecting hopper. Both the filter plate and the filter cylinder have multiple sets of filter holes inside, and the diameter of the filter holes inside the filter plate is larger than the diameter of the filter holes inside the filter cylinder.

[0011] As a preferred embodiment of this utility model, a connecting sleeve is fixedly installed on the outer side of the bottom end of the crushing shaft, and two sets of sweeping plates are fixedly connected to the outer side of the connecting sleeve.

[0012] As a preferred embodiment of this utility model, a sealing plate is fixedly connected to the back of the filter cylinder, and a material guide port is formed between the top of the sealing plate and the filter cylinder, with the bottom of the material guide hopper located inside the material guide port.

[0013] Compared with the prior art, the beneficial effects of this utility model are: In this invention, through the coordinated design of the frame, crushing cylinder, collecting hopper, filter cylinder, guide hopper, and discharge hopper, the compound fertilizer first enters the crushing cylinder for preliminary crushing. The crushed compound fertilizer and the insufficiently dispersed lumps are then introduced into the collecting hopper, and subsequently into the filter cylinder through the guide hopper. A first motor drives the drive shaft to rotate, and the drive sprocket at the front end of the drive shaft drives the transmission sprocket to rotate synchronously via a chain. The transmission sprocket drives the entire filter cylinder to rotate, and the rollers roll smoothly along the guide rail to ensure the stability of the filter cylinder during rotation. After the compound fertilizer enters the rotating filter cylinder through the guide hopper, the compound fertilizer inside the filter cylinder is subjected to centrifugal force and continuously collides with the filter cylinder wall during rotation, thereby further crushing the residual lumps. At the same time, the compound fertilizer inside the filter cylinder can fully contact the outside air, accelerating the dissipation of moisture. The fully crushed compound fertilizer is finally discharged through the discharge hopper. While ensuring the crushing effect, this design significantly improves the drying performance of the compound fertilizer, making it particularly suitable for the continuous production needs of high-humidity compound fertilizer.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Example: Please refer to Figures 1-3 This utility model provides a technical solution: A compound fertilizer anti-caking device includes a frame 1, a crushing cylinder 2 fixedly installed at the rear end of the top of the frame 1, a collecting hopper 3 fixedly connected to the bottom end inside the crushing cylinder 2, a filter cylinder 4 installed on the inner side of the front end of the frame 1, a guide hopper 5 fixedly installed at the bottom end of the collecting hopper 3, and the bottom end of the guide hopper 5 extending to the inner side of the filter cylinder 4, and a discharge hopper 6 fixedly installed on the inner side of the frame 1 and below the filter cylinder 4.

[0018] First, support frames 401 are fixedly installed on the inner side of the frame 1 at both the front and rear ends of the filter cylinder 4. Rollers 402 are rotatably connected to both ends of the support frames 401. Guide rails 403 are fixedly connected to the front and rear ends of the filter cylinder 4 at positions corresponding to the rollers 402. A first motor 404 is fixedly installed on the inner side of the rear end of the frame 1. A drive shaft 405 is fixedly installed on the drive end of the first motor 404. A drive sprocket 406 is fixedly installed at the front end of the drive shaft 405. A transmission sprocket 407 is fixedly installed at the rear end of the filter cylinder 4 at a position corresponding to the drive sprocket 406. The transmission sprocket 407 is connected to the drive sprocket 406 via a chain 408. The compound fertilizer is first crushed in the crushing cylinder 2. The crushed compound fertilizer and the insufficiently dispersed lumps are fed into the inside of the collection hopper 3, and then fed through the guide hopper. The compound fertilizer is introduced into the filter cylinder 4. The first motor 404 drives the drive shaft 405 to rotate. The drive sprocket 406 at the front end of the drive shaft 405 drives the transmission sprocket 407 to rotate synchronously through the chain 408. The transmission sprocket 407 drives the filter cylinder 4 to rotate as a whole. The roller 402 rolls smoothly along the guide rail 403 to ensure the stability of the filter cylinder 4 during rotation. After the compound fertilizer enters the rotating filter cylinder 4 through the guide hopper 5, the compound fertilizer inside the filter cylinder 4 is subjected to centrifugal force and continuously collides with the cylinder wall of the filter cylinder 4, thereby further breaking up the residual lumps. At the same time, the compound fertilizer inside the filter cylinder 4 can fully contact the outside air, accelerating the dissipation of moisture. The fully broken compound fertilizer is finally discharged through the discharge hopper 6. While ensuring the crushing effect, the drying performance of the compound fertilizer is significantly improved, which is particularly suitable for the continuous production needs of high-humidity compound fertilizer.

[0019] Furthermore, the bottom of the first motor 404 is fixedly connected to the frame 1 via the mounting base 409, and the front end of the drive shaft 405 is rotatably connected to the frame 1 via the bearing seat 410. The first motor 404 is rigidly fixed to the frame 1 via the mounting base 409 to ensure the stability of power output. The front end of the drive shaft 405 is rotatably connected to the frame 1 via the bearing seat 410 to achieve a smooth transition of power transmission.

[0020] Then, a feed pipe 201 is fixedly connected to one end of the top of the crushing cylinder 2, and a conical feed hopper 202 is fixedly connected to the top of the feed pipe 201. The compound fertilizer is naturally discharged through the flared design of the conical feed hopper 202, and then introduced into the interior of the crushing cylinder 2 through the feed pipe 201.

[0021] Furthermore, a second motor 203 is fixedly installed at the center of the top of the crushing cylinder 2. A rotating shaft 204 is fixedly installed at the drive end of the second motor 203. Multiple sets of crushing shafts 205 are fixedly connected to the outer side of the rotating shaft 204. Multiple sets of collision shafts 206 are fixedly connected to the inner wall of the crushing cylinder 2. When the compound fertilizer is introduced into the crushing cylinder 2, the second motor 203 is started and drives the rotating shaft 204 to rotate at a preset speed. The crushing shafts 205 on the outer side of the rotating shaft 204 rotate at high speed, generating shear force on the compound fertilizer to achieve primary crushing. The crushed material flies towards the cylinder wall under the action of centrifugal force and collides with the fixedly installed collision shafts 206 to complete secondary crushing.

[0022] A filter plate 207 is fixedly installed at the connection between the crushing cylinder 2 and the collecting hopper 3. Both the filter plate 207 and the filter cylinder 4 have multiple sets of filter holes 208. The diameter of the filter holes 208 inside the filter plate 207 is larger than that inside the filter cylinder 4. The compound fertilizer that has been initially crushed inside the crushing cylinder 2 leaks out through the larger diameter filter holes 208 on the upper part of the filter plate 207. The compound fertilizer and the insufficiently dispersed lumps are introduced into the collecting hopper 3 together. Then, it is introduced into the filter cylinder 4 through the guide hopper 5 for further crushing. The fully crushed compound fertilizer leaks out through the smaller diameter filter holes 208 inside the filter cylinder 4. Finally, it is discharged through the discharge hopper 6, thus ensuring the crushing effect of the compound fertilizer.

[0023] Secondly, a connecting sleeve 209 is fixedly installed on the outer side of the bottom end of the crushing shaft 205. Two sets of sweeping plates 210 are fixedly connected to the outer side of the connecting sleeve 209. The two sets of sweeping plates 210 are fixedly installed on the connecting sleeve 209 at the bottom end of the crushing shaft 205 and rotate synchronously with the crushing shaft 205. The sweeping plates 210 push the crushed material to the inner wall of the crushing cylinder 2 to prevent the compound fertilizer from accumulating at the bottom. At the same time, the rotation of the sweeping plates 210 can promote the material to enter the next process through the filter plate 207.

[0024] Finally, a sealing plate 501 is fixedly connected to the back of the filter cylinder 4. The top of the sealing plate 501 and the filter cylinder 4 form a guide port 502. The bottom of the guide hopper 5 is located inside the guide port 502. The sealing plate 501 is fixed to the back of the filter cylinder 4 and forms a guide port 502 with the filter cylinder 4 to prevent compound fertilizer from leaking out. The bottom of the guide hopper 5 extends into the guide port 502 to ensure that the compound fertilizer falls accurately into the interior of the filter cylinder 4, reducing dust and waste.

[0025] In this embodiment, the specific implementation scenario is as follows: Compound fertilizer is naturally discharged through the flared design of the conical feed hopper 202, and then introduced into the interior of the crushing cylinder 2 through the feed pipe 201. At this time, the second motor 203 has been started and drives the rotating shaft 204 to rotate at a preset speed. The crushing shaft 205 on the outside of the rotating shaft 204 rotates at high speed, generating shear force on the compound fertilizer to achieve primary crushing. The crushed material flies towards the cylinder wall under the action of centrifugal force and collides with the fixedly installed collision shaft 206 to complete secondary crushing. Two sets of sweeping plates 210 are fixedly installed on the connecting sleeve 209 at the bottom of the crushing shaft 205 and rotate synchronously with the crushing shaft 205. The sweeping plates 210 push the crushed material towards the inner wall of the crushing cylinder 2 to prevent the compound fertilizer from accumulating at the bottom. At the same time, the rotation of the sweeping plates 210 can promote the material to enter the next process through the filter plate 207. The compound fertilizer that has been initially crushed inside the crushing cylinder 2 leaks out through the larger diameter filter hole 208 on the upper part of the filter plate 207. The compound fertilizer and the insufficiently dispersed clumps are introduced into the collection. The compound fertilizer is fed into the hopper 3 and then guided into the filter cylinder 4 through the guide hopper 5 for further crushing. The first motor 404 drives the drive shaft 405 to rotate. The drive sprocket 406 at the front end of the drive shaft 405 drives the transmission sprocket 407 to rotate synchronously through the chain 408. The transmission sprocket 407 drives the filter cylinder 4 to rotate as a whole. The roller 402 rolls smoothly along the guide rail 403 to ensure the stability of the filter cylinder 4 during rotation. After the compound fertilizer enters the rotating filter cylinder 4 through the guide hopper 5, the compound fertilizer inside the filter cylinder 4 is subjected to centrifugal force and continuously collides with the cylinder wall, thereby further crushing the residual lumps. At the same time, the compound fertilizer inside the filter cylinder 4 can fully contact the outside air, accelerating the dissipation of moisture. The fully crushed compound fertilizer leaks out through the small diameter filter hole 208 inside the filter cylinder 4 and is finally discharged through the discharge hopper 6. The whole operation process is simple and convenient. This utility model significantly improves the drying performance of compound fertilizer while ensuring the crushing effect, and is particularly suitable for the continuous production needs of high-humidity compound fertilizer.
