Description

Technical Field

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

[0002] Countries around the world attach great importance to the issue of pesticide residues and have set increasingly strict limits on pesticide residues in various agricultural and sideline products. Agricultural products need to be tested for pesticide residues before use. The agricultural products are placed in a sampling device, and the surface of the agricultural products is washed and soaked with water. After obtaining the sample solution, the components in the sample are tested.

[0003] In existing technologies, pesticide residues in the surface or interior moisture of agricultural products need to be tested during the production process. However, the traditional testing method involves manually removing moisture from the surface of agricultural products for testing. This rudimentary sampling method results in poor testing results and low accuracy. Furthermore, it has limitations when dealing with broken, lumpy agricultural product samples. For example, some agricultural products have little juice, and after initial crushing, they are easily pushed to the edge of the crushing device, resulting in a large number of lumpy agricultural product samples not being fully crushed into a slurry, which affects the subsequent slurry testing data. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a sampling device for detecting pesticide residues in agricultural products. This device solves the problem that in existing agricultural product pesticide extraction equipment, after initial crushing, the samples are easily pushed to the edge of the crushing device, resulting in a large number of lumpy agricultural product samples not being fully crushed into a slurry, which affects the subsequent slurry detection data.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sampling device for detecting pesticide residues in agricultural products, comprising:

[0006] The main connecting and fixing mechanism is used to provide support and assembly for other mechanisms;

[0007] An impact extraction mechanism is installed on top of the main connecting and fixing mechanism to separate the solid-liquid composition of the agricultural product to be tested and extract the liquid. The impact extraction mechanism for separation is installed on top of and above the main connecting and fixing mechanism.

[0008] The swinging hybrid mechanism includes two sets, which are arranged in a left-right relative position inside the main connecting and fixing mechanism to provide swinging output force for the impact extraction mechanism.

[0009] The impact extraction mechanism includes a first working tank, a second working tank, a central fixing sleeve, a sliding handle, impact blocks, a barrier mesh, and an ultrasonic generating ring. The second working tank is fixedly connected to the top of the first working tank. The central fixing sleeve is fixedly connected to the center of the second working tank. The sliding handle is slidably fitted inside the central fixing sleeve. Impact blocks are fixedly connected to the opposite ends of the sliding handle. A barrier mesh is provided at the connection between the first working tank and the second working tank. An ultrasonic generating ring is provided at the center of the first working tank.

[0010] Preferably, the main connecting and fixing mechanism includes a main connecting shell, an outer connecting shell, an observation window and a supporting base, and the outer connecting shell is slidably sleeved on the upper part of the outer side wall of the main connecting shell.

[0011] Preferably, the swing mixing mechanism includes a linkage output shaft, a first rotating shaft seat, a bidirectional rotating frame, a second rotating shaft seat, an auxiliary rotating frame, a drive frame, a limiting slide rail, a linkage slide table, an output motor, an output screw, a central shaft frame, an observation level, and an impact damping ring. The first rotating shaft seat is rotatably connected to the bidirectional rotating frame, the second rotating shaft seat is rotatably connected to the auxiliary rotating frame, and the other end of the auxiliary rotating frame is rotatably connected to the middle of the bidirectional rotating frame. The drive frame is fixedly connected to the top of the main connecting shell and located inside the second rotating shaft seat. The limiting slide rail is fixedly connected to the middle of the inner wall of the drive frame.

[0012] Preferably, the output motor is fixedly connected to the side wall of a set of drive frames, the output screw is rotatably connected inside the set of drive frames, and the output end of the output screw is fixedly connected to the output end of the output motor.

[0013] Preferably, a linkage output shaft is slidably sleeved on the side wall between the drive frames, and the two ends of the linkage output shaft are respectively fixedly connected to the side wall of the linkage slide table. An impact damping ring is provided in the middle of the linkage output shaft.

[0014] Preferably, the central axis frame is fixedly connected to the top of the inner wall of the outer casing, and an observation level is connected to the middle of the central axis frame.

[0015] Preferably, the second rotating shaft seat is fixedly connected to the main connecting shell, and the first rotating shaft seat is fixedly connected to the outer side of the top wall of the outer connecting shell.

[0016] Preferably, the limiting slide rail is laterally slidably connected to the linkage slide table, and the side wall of the linkage slide table is rotatably connected to the other end of the bidirectional rotating frame.

[0017] Working Principle: First, by opening the sealed door at the top of the second working tank, place the crops to be tested on the left and right sides of the second working tank. Activate the two sets of oscillating mixing mechanisms. The corresponding output motors start, generating rotational torque that drives the output screw to rotate. The rotation of the output screw pushes the corresponding linkage slide of one set of oscillating mixing mechanisms outwards. The linkage slide then slides laterally along the limiting slide rail fixed inside the drive frame. The sliding of this linkage slide causes the added bidirectional rotating frame to rotate. The auxiliary rotating frame added in the middle of this bidirectional rotating frame also rotates and supports the rotating auxiliary rotating frame. The rotation of this bidirectional rotating frame causes one end of the outer sleeve connecting shell, which is rotated through a rotating shaft seat, to sink. Meanwhile, the other set of oscillating mixing mechanisms causes the outer sleeve connecting... The other end of the shell rises, causing the two sets of oscillating mixing mechanisms to work in a cycle, generating a surge-type output oscillating force. This causes the sliding handle connected to the shaft fixed sleeve inside the second working tank and the impact blocks installed at both ends of the sliding handle to oscillate laterally along the shaft fixed sleeve. The impact blocks on both sides of the sliding handle continuously impact and squeeze the crop under test through the surge oscillation force, causing the crop's own liquid to be squeezed out. With continuous impact, the solid-liquid separation of the crop is completed. The solid is blocked by the barrier separating net set between the first and second working tanks, while the liquid flows into the first working tank through the barrier separating net. At the same time, the ultrasonic generating ring inside the first working tank is activated. The ultrasonic generating ring generates ultrasonic impact, separating the pesticide liquid components contained in the separated liquid and suspending them above the mixture.

[0018] This invention provides a sampling device for detecting pesticide residues in agricultural products. It has the following beneficial effects:

[0019] 1. This invention activates two sets of oscillating mixing mechanisms. After the output motor starts, it generates rotational torque to drive the output screw to rotate. The rotation of the output screw pushes the linkage slide corresponding to one set of oscillating mixing mechanisms outward. The linkage slide then slides laterally along the limiting slide rail fixed inside the drive frame. The sliding of the linkage slide causes the bidirectional rotating frame installed on it to rotate. The auxiliary rotating frame installed in the middle of the bidirectional rotating frame also rotates and supports the rotating auxiliary rotating frame. The rotation of the bidirectional rotating frame causes one end of the outer sleeve connecting shell installed through the rotating shaft seat to sink, while the other set of oscillating mixing mechanisms causes the other end of the outer sleeve connecting shell to rise. This causes the two sets of oscillating mixing mechanisms to work in a cycle, generating a surge-like output oscillating force.

[0020] This invention utilizes a sliding handle connected to a central fixed sleeve inside the second working tank, along with impact blocks at both ends of the sliding handle, to reciprocate laterally along the central fixed sleeve. The impact blocks on both sides of the sliding handle continuously impact and squeeze the crop under test through surging oscillation force, causing the crop's own liquid to be squeezed out. With continuous impact, solid-liquid separation of the crop is completed. The solid is blocked by a barrier separating net set between the first and second working tanks, while the liquid flows into the first working tank through the barrier separating net. At the same time, the ultrasonic generating ring inside the first working tank is activated, and the ultrasonic generating ring generates ultrasonic impact, separating the pesticide liquid components contained in the separated liquid and suspending them above the mixture. The extraction and separation process is carried out simultaneously through surging driving force. Attached Figure Description
