Description

Technical Field

[0001] This application relates to the field of pesticide residue pretreatment, and more specifically, to an apparatus for pretreatment of organochlorine pesticide residues in agricultural products. Background Technology

[0002] With the continuous advancement of cultivation techniques, the growth period of agricultural products has become shorter and shorter. However, with the aggravation of environmental pollution, the pests and diseases affecting agricultural products are becoming more and more severe. Most agricultural products need to be treated with pesticides multiple times before they can mature and be sold on the market. Therefore, existing technologies often require testing the pesticide residue levels on the surface of agricultural products before they are put into the market, in order to prevent excessive pesticide content on the surface of agricultural products from harming the health of consumers.

[0003] In existing technologies, water rinsing can be used to pre-treat agricultural products for pesticide residues. However, in existing technologies, such as for corn products, the whole product is rinsed before the next batch is replaced, which reduces work efficiency.

[0004] An apparatus for pretreatment of organochlorine pesticide residues in agricultural products is now provided. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] To address the technical problems mentioned in the background section, some embodiments of this application provide an apparatus for pretreatment of organochlorine pesticide residues in agricultural products, comprising: two mounting frames; two support rods fixedly connected to the bottom ends of the mounting frames; two rotating shafts rotatably mounted between the two mounting frames; a conveyor belt driven between the two rotating shafts; a dual-shaft motor fixedly connected to the mounting frames, with the output shaft of the drive motor fixedly connected to one of the rotating shafts; multiple permeable holes evenly distributed on the conveyor belt; a mounting plate fixedly connected to one of the mounting frames; and an inlet... Multiple water pipes are fixedly attached to the mounting plate; an outlet pipe is connected to the inlet pipe and corresponds to the conveyor belt; multiple outlet holes are evenly distributed at the bottom of the outlet pipes; a receiving box is located at the bottom of the conveyor belt, with a screen-like bottom and one open end; a hinge plate is hinged to the receiving box and located at the open end; a fixing component is located between the hinge plate and the receiving box to fix the hinge plate vibration component, which is mounted on the support rod for the back-and-forth vibration of the receiving box; and a conveyor plate is fixedly attached to the mounting frame and is inclined.

[0007] When pre-treating corn for pesticide residues, the dual-shaft motor can be started first, causing its output shaft to drive the rotating shaft. Simultaneously, external water is supplied to the inlet pipe, then flows into the outlet pipe and is sprayed onto the conveyor belt through the outlet holes. Corn is then placed onto the conveyor belt in sequence, and the conveyor belt transports the corn. Under the rinsing action of the water, pesticide residues are removed. The treated water passes through the permeable holes, allowing some smaller impurities to pass through as well. These impurities are then conveyed out through the conveyor plate. By placing corn onto the conveyor belt in sequence during transport, the processing efficiency is improved. To improve efficiency, the corn falls into the receiving box under gravity. Simultaneously, when the dual-shaft motor starts, the second worm and second worm wheel cause the rotating bar to rotate, and the first worm and first worm wheel cause the rotating rod to rotate, which in turn causes the extrusion plate to rotate. This causes the extrusion plate to press against the disc, compressing the shaking spring. When the extrusion plate detaches from the disc, the spring causes the receiving box to shake, which in turn causes the corn to shake, thus allowing for screening. Furthermore, the mesh structure at the bottom of the receiving box further filters out impurities, improving overall quality. After screening, the fixing bolts can be rotated to open the hinge plate for unloading.

[0008] In some embodiments, the shaking assembly includes a shaking spring, two slide rods are fixedly connected to both ends of the receiving box, and the corresponding slide rods pass through the support rod and are slidably installed with the support rod. The shaking spring is fixed between the support rod and the receiving box and is sleeved on the slide rod. A disc is fixedly connected to the slide rod, and an extrusion assembly is provided on the support rod.

[0009] In some embodiments, the extrusion assembly includes a connecting seat fixed to a support rod, a rotating rod rotatably mounted on the connecting seat, an extrusion plate fixed to the rotating rod, and the extrusion plate corresponding to the disc, and a drive assembly is provided on the mounting frame.

[0010] In some embodiments, the drive assembly includes a first worm and a first worm wheel, a fixed bar is fixedly connected to the support rod, and a rotating bar is rotatably mounted on the fixed bar. The first worm is fixedly connected to the rotating bar, the first worm wheel is fixedly connected to the rotating rod, and the first worm meshes with the first worm wheel. A linkage assembly is provided between the rotating bar and the output shaft of the dual-axis motor.

[0011] In some embodiments, the linkage assembly includes a second worm and a second worm wheel, the second worm being fixed to the output shaft of the dual-axis motor, the second worm wheel being fixed to the rotating bar, and the second worm meshing with the second worm wheel.

[0012] In some embodiments, the fixing component includes a fixing bolt that is threadedly connected to the hinge plate and to the receiving box.

[0013] In some implementations, two fixing bolts are provided.

[0014] In some implementations, a handle is fixed to the hinge plate.

[0015] In some implementations, the handle is U-shaped.

[0016] In some implementations, an overlap plate is fixed to the support rod, and the overlap plate is located at the bottom of the receiving box.

[0017] The beneficial effects of this application are as follows: By setting up a conveyor belt and a receiving box, when pre-treatment of corn for pesticide residues is required, the dual-shaft motor can be started first, causing the output shaft of the dual-shaft motor to drive the rotating shaft to rotate. At the same time, external water can be supplied to the water inlet pipe, then the water enters the water outlet pipe, and finally sprayed onto the conveyor belt through the water outlet holes. Then, corn can be placed onto the conveyor belt in sequence. The conveyor belt transports the corn, and under the action of water rinsing, pesticide residues can be removed. Under the action of water permeability holes, the treated water can pass through, and some smaller impurities can also pass through. Then, they are conveyed out through the conveyor plate. When transporting corn, corn can be placed onto the conveyor belt in sequence. The process is streamlined, improving efficiency. The corn falls onto the receiving box under gravity. Simultaneously, when the dual-shaft motor starts, the second worm and second worm wheel cause the rotating bar to rotate, while the first worm and first worm wheel cause the rotating rod to rotate, which in turn causes the extrusion plate to rotate. This causes the extrusion plate to press against the disc, compressing the shaking spring. When the extrusion plate disengages from the disc, the spring causes the receiving box to shake, which in turn causes the corn to shake, allowing for screening. Furthermore, the mesh structure at the bottom of the receiving box further filters out impurities, improving overall quality. After screening, the fixing bolts can be rotated to open the hinge plate for unloading. Attached Figure Description

[0033] Working process: When pre-treatment of corn for pesticide residues is required, the dual-shaft motor 17 can be started first, causing the output shaft of the dual-shaft motor 17 to drive the rotating shaft 3 to rotate. At the same time, external water can be supplied to the inlet pipe 5, then the water enters the outlet pipe 4, and finally sprayed onto the conveyor belt 9 through the outlet hole 15.

Under the action of water permeability holes 7, the treated water can pass through, and some smaller impurities can also pass through. Then, it is transported out through the conveyor plate 16. When transporting corn, the corn can be placed onto the conveyor belt in sequence, thereby improving the processing efficiency. Under the influence of gravity, the material falls onto the receiving box 14. Simultaneously, when the dual-shaft motor 17 starts, the rotating bar 23 rotates under the action of the second worm 25 and the second worm wheel 24. Under the action of the first worm 18 and the first worm wheel 21, the rotating rod 27 rotates, causing the extrusion plate 20 to rotate.

When the extrusion plate 20 disengages from the disc 19, the spring causes the receiving box 14 to shake, which in turn causes the corn to shake, thus enabling screening. Furthermore, since the bottom of the receiving box 14 has a mesh structure, impurities are further screened out, improving the overall quality. After screening, the fixing bolts can be rotated to open the hinge plate 10 for unloading.
