Description

Technical Field

[0001] This utility model relates to the field of agricultural product inspection technology, and in particular to an inspection device for agricultural product residues. Background Technology

[0002] Agricultural products are items produced in agriculture, such as sorghum, rice, peanuts, corn, wheat, and local specialties. Current technology for detecting residues in agricultural products generally involves rinsing the agricultural products and then testing the wastewater.

[0003] A search revealed Chinese patent CN215339179U, which discloses a device for detecting residues in agricultural products, relating to the field of pesticide detection technology. This utility model includes a collection box with positioning plates fixed to both sides. Positioning rods are fixed to the upper surface of the positioning plates. A washing box is movably connected inside the collection box, with movable plates fixed to both sides. Adjustment grooves are formed on the surface of the movable plates, and a positioning hole is formed on one side of each movable plate. The washing box consists of mesh panels. A fixed plate is fixed to one side of the collection box, and an adjuster is fixed to one side of the fixed plate. The adjuster includes a housing with a tension spring fixed inside. A movable plate is fixed to one end of the tension spring, a locking rod is fixed to the upper surface of the movable plate, and a connecting rod is fixed to the bottom of the movable plate. This utility model utilizes the function of the washing box, which moves within the collection box. This device can flexibly clean agricultural products, and compared to traditional rinsing, it can extract pesticides from the surface of agricultural products with a measured amount of clean water, resulting in more accurate detection results.

[0004] This patent uses a quantitative amount of water to extract residues from the surface of agricultural products, which improves the accuracy of detection. After the agricultural products are tested, the staff needs to remove the agricultural products from the cleaning box. However, in this patent, whether the cleaning box is removed to empty the agricultural products and then reinstalled, or the agricultural products are removed directly without removing the cleaning box, it is time-consuming. This means that unloading the agricultural products after testing is inconvenient, which reduces the efficiency of agricultural product residue detection.

[0005] Therefore, we have made improvements to this and proposed a testing device for residues in agricultural products. Utility Model Content

A linkage plate is fixedly connected to the ends of the two sliding rods away from the spring. A motor is fixedly connected to the upper half of the side wall of the collection box. A drive rod is driven to the output end of the motor. The drive rod rotates through the collection box, and a plurality of cams are fixedly sleeved on the outer circumference of the drive rod. The cams intermittently contact the linkage plate when they rotate.

[0011] As a preferred technical solution of this application, the sealing part includes a sealing plate that slides through the upper half of the discharge pipe. The side wall of the sealing plate is in contact with the side wall of the collection box, and the sealing plate covers the discharge port. Two vertical rods are fixedly connected to the top of the sealing plate, and a driven plate is fixedly connected to the top of the two vertical rods.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of 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.

[0025] Example:

[0026] Reference Figure 1-5 A testing device for agricultural product residues includes a collection box 1 with an open top, a discharge pipe fixed to the bottom of the collection box 1, a valve fixed to the outer periphery of the discharge pipe, a detector 2 fixed to the bottom of the collection box 1, a washing cylinder 3 arranged in the upper part of the collection box 1, a feeding frame 4 fixedly inserted through the top of the washing cylinder 3, a vibration part 5 arranged on the outer side of the washing cylinder 3, a drive part 6 arranged on opposite sides of the collection box 1, a guide arc plate 7 fixedly connected to the lower part of the collection box 1, a discharge pipe 8 fixedly connected to one side of the collection box 1, the guide arc plate 7 is inclined downward towards the side of the discharge pipe 8, and a discharge port 9 is opened on the side wall of the collection box 1 inside the discharge pipe 8, and a sealing part 10 is arranged inside the discharge pipe 8.

[0027] Both the washing cylinder 3 and the guide arc plate 7 have hollowed-out surfaces, preventing agricultural products from passing through them, while allowing water to pass through freely.

[0028] In the initial state, the feed frame 4 is located directly above the washing cylinder 3, and the valve is closed. When detecting agricultural product residues, the agricultural products are poured into the washing cylinder 3 through the feed frame 4, and then water is added to the collection box 1. The water surface covers the agricultural products in the washing cylinder 3, so that pesticide and other residues on the surface of the agricultural products dissolve into the water. Then the valve is opened, and the water enters the detector 2 through the discharge pipe, thereby detecting the residues on the surface of the agricultural products.

[0029] like Figure 4As shown, in a preferred embodiment, based on the above method, the drive unit 6 further includes two rotating drums 61 that are rotatably disposed on opposite sides of the collection box 1. Square rods 62 are fixedly connected to opposite sides of the washing drum 3. The square rods 62 are partially slidably inserted into the corresponding rotating drums 61. A drive member 63 is provided on one side of the collection box 1. The drive member 63 is used to drive the corresponding rotating drums 61 to rotate.

[0030] The drive unit 63 includes a servo motor fixedly connected to the side wall of the collection box 1. The servo motor is connected to a rotating drum 61 through a pair of gears. When the servo motor works, it drives the rotating drum 61 to rotate. The rotating drum 61 drives the corresponding square rod 62 and the cleaning drum 3 to rotate. The cleaning drum 3 drives another square rod 62 and the rotating drum 61 to rotate. Therefore, when the drive unit 63 works, the two rotating drums 61, the two square rods 62 and the cleaning drum 3 rotate synchronously, and the drive unit 63 drives the cleaning drum 3 to rotate half a turn once.

[0031] like Figure 2-5 As shown, in a preferred embodiment, based on the above method, the vibration unit 5 further includes two sliding grooves 51 opened on the inner walls of opposite sides of the collection box 1. A turntable 52 is rotatably sleeved on the outer circumferential surface of the washing cylinder 3. A sliding rod 58 is slidably connected in the sliding groove 51. Both turntables 52 are fixedly connected to the sliding rods 58. A spring 53 is fixedly connected between one of the turntables 52 and the inner side wall of the sliding groove 51. The ends of the two sliding rods 58 away from the spring 53 are jointly fixedly connected to a linkage plate 54. A motor 55 is fixedly connected to the upper half of the side wall of the collection box 1. A drive rod 56 is drivenly connected to the output end of the motor 55. The drive rod 56 rotates through the collection box 1, and a plurality of cams 57 are fixedly sleeved on the outer circumferential surface of the drive rod 56. When the cams 57 rotate, they intermittently contact the linkage plate 54.

[0032] Since the two turntables 52 are fixedly connected to the two sliding rods 58, and the sliding rods 58 are slidably connected in the corresponding grooves 51, the two turntables 52 can only move horizontally. When the turntables 52 move horizontally, they drive the cleaning cylinder 3 to move horizontally. The cleaning cylinder 3 drives the two square rods 62 to slide in the corresponding turntable 61.

[0033] When motor 55 is working, it drives drive rod 56 to rotate, and drive rod 56 drives cam 57 to rotate. When cam 57 rotates, it contacts linkage plate 54 and pushes linkage plate 54 to move. When cam 57 disengages from linkage plate 54, linkage plate 54 moves in the opposite direction under the restoring force of spring 53. Therefore, linkage plate 54 will move horizontally back and forth, driving sliding rod 58, turntable 52 and washing cylinder 3 to move horizontally back and forth. This causes relative motion between agricultural products and water when the agricultural products are soaked in water, allowing residues to dissolve better in the water, thereby improving detection accuracy.

[0034] like Figure 1 and Figure 4As shown, in a preferred embodiment, based on the above method, the sealing part 10 further includes a sealing plate 101 that slides through the upper half of the discharge pipe 8. The side wall of the sealing plate 101 is in contact with the side wall of the collection box 1, and the sealing plate 101 covers the discharge port 9. Two vertical rods 102 are fixedly connected to the top of the sealing plate 101, and a driven plate 103 is fixedly connected to the top of the two vertical rods 102. Two side plates 104 are fixedly connected to the side wall of the collection box 1. The vertical rods 102 slide through the corresponding side plates 104, and a spring 105 is fixedly connected between the top of the sealing plate 101 and the corresponding side plate 104. An elliptical wheel 106 is fixedly sleeved on the outer circumferential surface of the rotating drum 61, and the elliptical wheel 106 is located below the driven plate 103.

[0035] In the initial state, the sealing plate 101 covers the discharge port 9, and the water flow cannot pass through the discharge port 9. When the rotating drum 1 rotates, it drives the elliptical wheel 106 to rotate. The elliptical wheel 106 drives the driven plate 103 to move upward, thereby driving the vertical rod 102 and the sealing plate 101 to move upward, so that the discharge port 9 is exposed and agricultural products can pass through the discharge port 9.

[0036] like Figure 4-5 As shown, in a preferred embodiment, based on the above method, a screw 11 is rotatably inserted through one side of the collection box 1. The screw 11 is located inside the guide arc plate 7. A motor 12 is fixedly connected to one side of the collection box 1. The output end of the motor 12 is connected to the screw 11 for transmission. A push plate 13 is threadedly connected to the outer circumference of the screw 11. The bottom surface of the push plate 13 is in contact with the top surface of the guide arc plate 7. A limiting part is provided on the outer side of the push plate 13.

[0037] The limiting part includes two limiting grooves 14 respectively opened on the lower half of the inner wall of opposite sides of the collection box 1. The push plate 13 is fixedly connected to the limiting blocks 15 on opposite sides. The limiting blocks 15 are slidably connected in the corresponding limiting grooves 14. The cooperation between the limiting blocks 15 and the limiting grooves 14 is used to limit the push plate 13, so that the push plate 13 can only move linearly along the extension direction of the limiting grooves 14, and will not rotate with the screw 11.

[0038] After the agricultural products in the washing drum 3 are completely poured out, the motor 12 is started to drive the push plate 13 to move toward the discharge pipe 8, thereby pushing the agricultural products on the guide plate 7 into the discharge pipe 8.

[0039] Specifically, when the equipment for testing residues in this agricultural product is in operation:

[0040] When detecting residues in agricultural products, the agricultural products are poured into the washing cylinder 3 through the feeding frame 4, and then water is added to the collection box 1. The water surface covers the agricultural products in the washing cylinder 3. The motor 55 works, driving the washing cylinder 3 to move horizontally back and forth, so that the agricultural products and water are in relative motion, and the residues in the agricultural products are better dissolved in the water. Then the valve is opened, and the water enters the detector 2 through the discharge pipe, thereby detecting the residues on the surface of the agricultural products.

[0041] After the water is discharged from the collection box 1, the drive unit 63 is started, driving the two rotating drums 61, the two square rods 62 and the washing drum 3 to rotate synchronously until the washing drum 3 rotates half a turn. Under the action of gravity, the agricultural products in the washing drum 3 pass through the feeding frame 4 and fall onto the guide arc plate 7, and move towards the discharge pipe 8 under the action of gravity. When the rotating drum 61 rotates, it drives the sealing plate 101 to move upward through the elliptical wheel 106, thereby exposing the discharge port 9. The agricultural products on the guide arc plate 7 can pass through the discharge port 9 and the discharge pipe 8, thereby discharging the agricultural products. When the agricultural products in the washing drum 3 are completely poured out, the motor 12 is started, driving the push plate 13 to move towards the discharge pipe 8, thereby fully pushing the agricultural products on the guide arc plate 7 into the discharge pipe 8, improving the discharge effect.

[0042] After the material is discharged, motor 12 reverses to adjust push plate 13 to its initial position, and drive component 63 reverses to restore cleaning cylinder 3 and sealing plate 101 to their initial positions.

[0043] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
