Description

Technical Field

[0001] This utility model relates to the field of agricultural product testing technology, specifically to a device for detecting pesticide residues in agricultural products. Background Technology

[0002] The development of agricultural industrialization has made agricultural production increasingly reliant on exogenous substances such as pesticides, antibiotics, and hormones. The amount of pesticides used in agricultural products in my country remains high, and the irrational use of these substances inevitably leads to excessive pesticide residues in agricultural products, affecting consumer safety. Therefore, in order to reduce the damage caused by pesticide residues, detecting pesticide residues in agricultural products has become a top priority in agricultural product quality testing.

[0003] When testing for pesticide residues, the agricultural products must first be crushed and compressed to extract the juice or residue for analysis. Currently, the common practice is to first crush the agricultural products to be tested in a crusher, and then use a compression device to press the crushed residue, collecting the extracted juice or residue for analysis. This pre-testing process requires two separate operations, making the entire testing process complex, reducing efficiency, and increasing costs and intensity.

[0004] Therefore, we propose a device for detecting pesticide residues in agricultural products. Utility Model Content

[0005] In view of the above situation and to overcome the shortcomings of the existing technology, this utility model provides a device for detecting pesticide residues in agricultural products.

[0006] The technical solution adopted by this utility model is as follows: This utility model provides a pesticide residue detection device for agricultural products, including a base, a crushing cylinder, and an extrusion box. Two sets of columns are fixedly installed on the base. The crushing cylinder is rotatably installed between the columns. The extrusion box is fixed to the bottom of the crushing cylinder, and the two are connected. An extrusion discharge pipe is provided at the bottom of the extrusion discharge pipe. A sealing cap is threaded onto the extrusion discharge pipe. A drain pipe is provided on the sealing cap. A detection platform is provided on the base. The drain pipe points to the detection platform. A crushing shaft is rotatably installed on the top of the crushing cylinder through a bearing. A crushing blade is provided on the crushing shaft. A drive assembly is installed on the base. After the crushing shaft is rotated to the bottom with the crushing cylinder, it is connected to the drive assembly for transmission. Sliding rods slide through the inner walls on both sides of the extrusion box. An extrusion plate is fixedly connected to one end of the sliding rod located inside the extrusion box.

[0007] Furthermore, the drive assembly includes a drive shaft and a vertical shaft. A drive groove is provided in the middle of the base. The drive shaft rotates through the inner wall of the front side of the drive groove via a bearing. The bottom end of the vertical shaft is rotatably mounted to the bottom of the drive groove via a bearing. A bevel gear one is fixedly connected to one end of the drive shaft located in the drive groove. A bevel gear two is fixedly connected to the vertical shaft. The bevel gear one meshes with the bevel gear two. A latch is provided at the top of the vertical shaft. A locking block is fixedly connected to one end of the crushing shaft located outside the crushing cylinder. The locking block engages with the latch after rotating to the bottom. A rotating handle one is fixedly connected to one end of the drive shaft located outside the drive groove.

[0008] Furthermore, a limiting plate is fixedly connected to one end of the sliding rod outside the extrusion box, and a spring is slidably sleeved on the sliding rod. The spring abuts against the limiting plate and the side wall of the extrusion box. An extrusion rod slides through the column, with one end of the extrusion rod in contact with the limiting plate and the other end of the extrusion rod fixedly connected to an operating plate.

[0009] Furthermore, horizontal shafts are fixed to both sides of the crushing cylinder, and one end of the horizontal shaft rotates through the column via a bearing. One end of one of the horizontal shafts is fixed to a worm gear, and a worm gear meshing with the worm gear is rotatably mounted on one of the columns. One end of the worm gear is fixed to a rotating handle.

[0010] Furthermore, a fixing rod is fixedly connected to the center of the bottom of the sealing cover, and a filter plate is fixedly connected to the fixing rod. The filter plate extends out of the sealing cover, and the circumferential sidewall of the filter plate slides and rotates in a sealing fit with the inner wall of the extrusion discharge pipe.

[0011] Furthermore, the top of the filter plate is flush with the bottom of the extrusion chamber.

[0012] Furthermore, the crushing shaft is coaxial with the vertical shaft.

[0013] The beneficial effects of this utility model by adopting the above structure are as follows:

[0014] 1. This device integrates the functions of crushing, squeezing and filtration of agricultural products into one unit. The crushing station and the squeezing station can be quickly switched by flipping the crushing cylinder. There is no need to transfer agricultural products between multiple independent devices, which effectively simplifies the pre-treatment process before testing, greatly shortens the overall testing time, and solves the problem of low efficiency in traditional step-by-step operation.

[0015] 2. In the crushing stage, the drive assembly drives the crushing shaft and crushing blades to rotate at high speed, which can efficiently cut and crush agricultural products. In the extrusion stage, the extrusion plates on both sides are brought closer together to apply force. With the filter plate flush with the bottom of the extrusion box, the residual juice in the crushed residue can be fully extracted to ensure sufficient extraction of the test sample (juice).

[0016] 4. This device achieves the tilting adjustment of the crushing cylinder through a worm gear and worm wheel transmission structure. The worm gear and worm wheel transmission has a reverse self-locking function, which can stably fix the crushing cylinder in the crushing or extrusion position without the need for an additional locking mechanism. After extrusion, the extrusion plate can be automatically reset by a spring. The sealing cover is rigidly connected to the filter plate, which is convenient for disassembly and assembly, and facilitates subsequent slag cleaning and equipment maintenance.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] like Figures 1-7 As shown, this utility model discloses a pesticide residue detection device for agricultural products, comprising a base 1, a crushing cylinder 2, and an extrusion box 3. Two sets of columns 4 are fixedly mounted on the base 1, and the crushing cylinder 2 is rotatably installed between the columns 4. The extrusion box 3 is fixed to the bottom of the crushing cylinder 2, and the two are connected. The bottom of the extrusion box 3 is provided with an extrusion discharge pipe 5, and the outer wall of the extrusion discharge pipe 5 is provided with an external thread. A sealing cover 6 is sleeved on the external thread. The sealing cover 6 is provided with a drain pipe 7 with a valve 32. A detection platform 8 is provided on the base 1, and the drain pipe 7 points to the detection platform 8. A crushing shaft 9 is rotatably mounted on the top of the crushing cylinder 2 through a bearing. A crushing blade 10 is provided on the crushing shaft 9. A drive assembly 11 is installed on the base 1. After the crushing shaft 9 is flipped to the bottom with the crushing cylinder 2, it is connected to the drive assembly 11 for transmission. Sliding rods 12 slide through the inner walls on both sides of the extrusion box 3, and an extrusion plate 13 is fixedly connected to one end of the sliding rod 12 located inside the extrusion box 3.

[0029] Working principle: The crushing cylinder 2 is rotatably connected to the column 4. By flipping the crushing cylinder 2, the crushing station (with the extrusion box 3 on top) and the extrusion station (with the extrusion box 3 on the bottom) can be switched to adapt to the needs of different operation stages. When switching to the crushing station, the crushing shaft 9 and the drive component 11 form a transmission connection. The drive component 11 drives the crushing shaft 9 and the crushing blades 10 to rotate, thus completing the crushing of agricultural products. After switching to the extrusion station, the crushing shaft 9 and the drive component 11 separate. The crushed agricultural product residue falls into the extrusion box 3 under the action of gravity. Then, by operating the extrusion plates 13 on both sides to come closer together and extrude the agricultural product residue, the juice in the agricultural product residue is squeezed out.

[0030] like Figures 1-7As shown, the drive assembly 11 includes a drive shaft 14 and a vertical shaft 15. A drive groove 16 is provided in the middle of the base 1. The drive shaft 14 rotates through the inner wall of the front side of the drive groove 16 via a bearing. The bottom end of the vertical shaft 15 is rotated and installed at the bottom of the drive groove 16 via a bearing. A bevel gear 17 is fixedly connected to one end of the drive shaft 14 located in the drive groove 16. A bevel gear 18 is fixedly connected to the vertical shaft 15. The bevel gear 17 and the bevel gear 18 mesh. A latch 19 is provided at the top of the vertical shaft 15. A locking block 20 is fixedly connected to one end of the crushing shaft 9 located outside the crushing cylinder 2. After the locking block 20 rotates to the bottom, it engages with the latch 19. A rotating handle 21 is fixedly connected to one end of the drive shaft 14 located outside the drive groove 16. The crushing shaft 9 and the vertical shaft 15 are coaxial.

[0031] When the crushing cylinder 2 is flipped to the crushing station, the locking block 20 at the outer end of the crushing shaft 9 will rotate downward and lock into the locking slot 19 at the top of the vertical shaft 15. When the vertical shaft 15 rotates under the action of bevel gear transmission, the torque is stably transmitted to the crushing shaft 9 through the square fit structure of the locking slot 19 and the locking block 20, which drives the crushing shaft 9 and the crushing blades 10 on the shaft to rotate at high speed, and finally realizes the cutting and crushing operation of agricultural products in the crushing cylinder 2.

[0032] like Figures 1-7 As shown, one end of the sliding rod 12 located outside the extrusion box 3 is fixedly connected to a limiting plate 22. A spring 23 is slidably sleeved on the sliding rod 12. The spring 23 abuts against the limiting plate 22 and the side wall of the extrusion box 3. An extrusion rod 24 is slidably passed through the column 4. One end of the extrusion rod 24 contacts the limiting plate 22, and the other end of the extrusion rod 24 is fixedly connected to an operating plate 25.

[0033] When squeezing agricultural products, the operator presses the operating plates 25 on both sides of the squeezing box 3 with both hands simultaneously. The operating plates 25 transmit the axial force applied manually to the squeezing rod 24, causing the squeezing rod 24 to slide along the through hole of the column 4 towards the squeezing box 3. During the sliding process, the end of the squeezing rod 24 abuts against the limiting plate 22 and pushes the limiting plate 22 to move synchronously. The limiting plate 22 transmits the axial thrust to the sliding rod 12, causing the sliding rod 12 to slide along the through hole of the squeezing box 3 into the box, thereby driving the squeezing plate 13 inside the squeezing box 3 to move towards the center. The two squeezing plates 13 on both sides move closer together, applying pressure to the agricultural product residue on the filter plate 31 inside the squeezing box 3, fully squeezing out the residual juice in the residue. After squeezing is completed, the operator releases the operating plates 25, and the originally compressed spring 23 releases its elastic potential energy, generating a reverse thrust to push the limiting plate 22 away from the squeezing box 3, thereby driving the squeezing plate 13 to reset through the sliding rod 12. When the squeezing box 3 is flipped, the squeezing rod 24 does not interfere with the flipping of the squeezing box 3.

[0034] like Figures 1-7As shown, horizontal shafts 26 are fixed to both sides of the crushing cylinder 2. One end of the horizontal shaft 26 rotates through the column 4 via a bearing. One end of one of the horizontal shafts 26 is fixed to a worm gear 27. A worm 28 that meshes with the worm gear 27 is rotatably installed on the column 4. A rotating handle 29 is fixed to one end of the worm 28.

[0035] The worm gear 27 and worm 28 transmission have a reverse self-locking function, which allows the crushing cylinder 2 to be flipped to the target position and then stably maintained at the current position without the need for an additional locking mechanism.

[0036] like Figures 1-7 As shown, a fixing rod 30 is fixedly connected to the center of the bottom of the sealing cover 6. A filter plate 31 is fixedly connected to the fixing rod 30. The filter plate 31 extends out of the sealing cover 6. The fixing rod 30 achieves a rigid connection between the filter plate 31 and the sealing cover 6, ensuring that the two are disassembled and assembled synchronously. The circumferential side wall of the filter plate 31 slides and rotates in a sealing fit with the inner wall of the extrusion discharge pipe 5. The filter plate 31 is a rigid plate, and its top is flush with the bottom of the extrusion box 3, ensuring that the extrusion plate 13 slides against the top of the filter plate 31. The bottom of the filter plate 31 is also equipped with filter gauze for fine filtration of the juice.

[0037] In practical use, first turn the handle 29 to rotate the worm gear 28, which in turn rotates the worm wheel 27, which in turn rotates the horizontal shaft 26 and the crushing cylinder 2. This positions the extrusion box 3 above the crushing cylinder 2, and moves the locking block 20 on the crushing shaft 9 into the locking slot 19 on the vertical shaft 15. At this point, the vertical shaft 15 and the crushing shaft 9 are connected. Then, the agricultural product to be tested is fed into the extrusion box 3 through the extrusion discharge pipe 5. The agricultural product passes through the extrusion box 3 and enters the crushing cylinder 2, where it interacts with the crushing blades. 10. After contact, tighten the sealing cover 6 onto the extrusion discharge pipe 5. At this time, the filter plate 31 is flush with the bottom of the extrusion box 3. Then, by rotating the first rotating handle 21, the drive shaft 14 is rotated. Through the meshing transmission of the first bevel gear 17 and the second bevel gear 18, the vertical shaft 15 is rotated. Since the clamping block 20 is square, the rotation of the vertical shaft 15 will drive the crushing shaft 9 to rotate, which in turn drives the crushing blade 10 to crush the agricultural product to be tested. After crushing, rotate the second rotating handle 29 again to make the extrusion box 3 position in the powder position. Below the crushing cylinder 2, the vertical shaft 15 separates from the crushing shaft 9. The crushed agricultural product residue inside the crushing cylinder 2 falls onto the filter plate 31, while the juice flows downwards into the sealing cover 6. Simultaneously, the operator presses the operating plates 25 on both sides, causing the extrusion rod 24 to move the limiting plate 22 and the sliding rod 12 towards one side of the extrusion box 3. This causes the extrusion plate 13 inside the extrusion box 3 to move relative to each other, thereby extruding the agricultural product residue on the filter plate 31. This causes the residual juice within the agricultural product residue to flow downwards, and the filter plate 31... A filter gauze (not shown in the figure) is also fixed to the bottom. The filter gauze covers the entire bottom of the filter plate 31 to finely filter the flowing agricultural product juice. Open the valve 32 on the drain pipe 7 to discharge the filtered agricultural product juice through the drain pipe 7 to the testing table 8. The testing table 8 is equipped with a pesticide residue test card to test the agricultural product juice for pesticide residues. After the test is completed, remove the sealing cover 6 from the extrusion pipe 5 and remove the filter plate 31 from the extrusion pipe 5 together, so that the agricultural product residue in the extrusion box 3 can be discharged.
