A sorting machine convenient for pesticide residue detection

Abstract

This invention discloses a sorting machine for easy pesticide residue detection. It includes a base with an internal drive shaft and a driven shaft on one side of the drive shaft, connected to the driven shaft via a conveyor belt. In this sorting machine, operators can control the synchronous extension and retraction of a first and second electric telescopic rod to adjust the tilt direction of the diversion seat, i.e., the diversion direction. Vegetables of different sizes falling from the gaps in the screening cylinder are guided into the hopper. The vegetables inside the hopper fall into a storage bin. Simultaneously, a crushing frame, driven by a chain drive structure, rotates along with the driven shaft. The rotating crushing frame drives the crushing blades to stir and crush the vegetables in the storage bin. The resulting juice is filtered through a screen and discharged through a discharge port into a storage box containing a detection reagent. When the reagent changes color, it indicates the presence of pesticide residues in the vegetables. The detection process is convenient and quick.

Description

Technical Field

[0001] This invention relates to the field of vegetable sorting machine technology, specifically a sorting machine that facilitates pesticide residue detection. Background Technology

[0002] A vegetable sorting machine, as the name suggests, is an auxiliary device used to sort vegetables. It is widely used for sorting potatoes, head vegetables, and other round vegetables. A search revealed that a typical existing vegetable sorting machine is disclosed in CN214235092U, a novel vegetable sorting machine, which includes a support base. A conveying mechanism is installed on the inner wall of one opposite side of the support base. A fixed seat is bolted to the top side of the support base. A spraying mechanism is installed on the outer wall of the opposite side of the fixed seat. A connecting seat is bolted to the outer wall of the top side of the support base. Three fans are bolted to the outer wall of the bottom side of the connecting seat. A sorting mechanism is installed on the outer wall of the top side of the support base near the connecting seat. Two slide rails are welded to one outer wall of the support base, and two collection boxes are slidably connected to the outer walls of the two slide rails. Two material troughs are bolted to the outer wall of the top side of the support base. A controller is bolted to the outer wall of one outer wall of the support base. Its main feature is that by starting the water pump, the water pump delivers the liquid in the water tank to the connecting pipe through the delivery pipe. The connecting pipe then delivers the liquid to the nozzle through the spray pipe, spraying it out to wash the vegetables and remove residue from the surface of the vegetables.

[0003] In summary, most existing vegetable sorting machines are equipped with spraying mechanisms to pre-wash vegetables. However, these spraying mechanisms typically rinse the vegetables from top to bottom, resulting in significant blind spots and inadequate cleaning. Furthermore, most existing vegetable sorting machines lack pesticide residue detection capabilities, requiring manual sampling and transfer to other equipment for crushing and juice extraction, which is inconvenient. To address these issues, improvements to the existing equipment are necessary. Summary of the Invention

[0004] The purpose of this invention is to provide a sorting machine that facilitates pesticide residue detection, in order to solve the problems mentioned in the background art. Most existing vegetable sorting machines are equipped with spraying mechanisms to pre-wash vegetables, but these spraying mechanisms mostly rinse the vegetables from top to bottom, resulting in large cleaning dead zones and thus easily leading to insufficient cleaning. On the other hand, most existing vegetable sorting machines do not have pesticide residue detection functions, that is, they require manual sampling and then transferring the samples to other equipment for crushing and juice extraction, which is not convenient to operate.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sorting machine for easy pesticide residue detection, comprising a base and a diverting seat.

[0006] The base is equipped with a drive shaft inside, and a driven shaft is provided on one side of the drive shaft. The drive shaft is connected to the driven shaft via a conveyor belt. The drive shaft is connected to the driven mechanism and the output end of the motor. A cleaning hood is provided above the conveyor belt and is fixedly connected to the top of the base. A screening cylinder is provided on the side of the driven shaft away from the drive shaft.

[0007] The diversion seat is located below one side of the screening cylinder, and a hopper is provided on one side of the diversion seat. A cleaning pipe network is connected to the hopper, and both the cleaning pipe network and the cleaning hood are connected to an external water supply device. A material barrel is connected to the bottom of the hopper, and a crushing rack is provided inside the material barrel. A crushing blade is connected to the crushing rack, and a filter screen is provided below the crushing blade. The filter screen is fixedly installed inside the material barrel and is rotatably connected to the crushing rack. A discharge port is connected to the bottom of the material barrel, and a storage box is provided below the discharge port. The storage box is slidably connected to a bracket, and the bracket is fixedly connected to the bottom of the material barrel. A cleaning door is rotatably connected to the front outer wall of the material barrel.

[0008] Preferably, the conveyor belt has uniformly spaced mesh openings, and the conveyor belt is disposed inside the base.

[0009] Preferably, the driven mechanism includes a first driven rod, a cam, a gear plate, and a second driven rod, and both the first driven rod and the second driven rod are provided with cams, while the first driven rod is connected to a gear plate.

[0010] Preferably, the first driven rod is evenly distributed between the drive shaft and the driven shaft, and the first driven rod is connected to the drive shaft through a belt drive structure.

[0011] Preferably, the first driven rods are connected by a gear plate, and the rotation directions of adjacent sets of first driven rods are opposite.

[0012] Preferably, the second driven rod is disposed below the diverter seat, and the second driven rod is connected to one end of the driven shaft through a bevel gear transmission structure. At the same time, the diverter seat is connected to the base through the first electric telescopic rod and the second electric telescopic rod.

[0013] Preferably, the cam on the second driven rod and the cam on the first driven rod respectively contact the bottom of the conveyor belt and the diverter seat.

[0014] Preferably, the cleaning hood has an arc-shaped cross-section, and the inner wall of the cleaning hood is evenly distributed with nozzles, while a monitoring probe is set at the center of the cleaning hood.

[0015] Preferably, the diverter seat and the screening cylinder are alternately arranged inside the base, and the screening cylinders are connected by a belt drive structure. Meanwhile, the width of the diverter seat increases from left to right, the screening cylinder is connected to the driven shaft by a belt drive structure, and the spacing between the screening cylinders increases from left to right.

[0016] Preferably, the crushing rack is connected to the drive shaft via a chain drive structure, and the drive shaft is fixedly connected to the outer wall of the base via a fixed seat. At the same time, the drive shaft is connected to the other end of the driven shaft via a bevel gear drive structure.

[0017] Compared with the prior art, the beneficial effects of the present invention are: this sorting machine facilitates pesticide residue detection.

[0018] (1) The present invention can effectively solve the problem that most existing vegetable sorting machines are equipped with a spray mechanism to pre-clean the vegetables by using the cleaning hood, base and first driven rod. However, most of their spray mechanisms are used to rinse the vegetables from top to bottom, resulting in a large cleaning dead angle and thus the problem of insufficient cleaning. Driven by the motor, the drive shaft and driven shaft rotate to drive the conveyor belt and the vegetables above it to move from left to right. At the same time, with the cooperation of the belt drive, the first driven rod will drive the cam to rotate with the rotation of the drive shaft. When the convex point on the rotating cam rotates to the bottom of the conveyor belt, it will push the conveyor belt upward, so that the vegetables on the conveyor belt will rotate, making it easier for the spray nozzle on the cleaning hood to spray and rinse them. At the same time, the arc-shaped cleaning hood can rinse the vegetables from the front, back and sides and the top in multiple directions, thereby ensuring the cleaning quality and cleaning efficiency of the vegetables. Meanwhile, the wastewater generated by rinsing will be discharged into the interior of the base through the mesh on the conveyor belt for storage, thereby avoiding the wastewater from flowing and polluting the working environment.

[0019] (2) This invention effectively solves the problem that most existing vegetable sorting machines do not have pesticide residue detection functions, i.e., they require manual sampling and then transfer to other equipment for crushing and juice extraction, which is inconvenient to operate. The second driven rod, with the cooperation of the bevel gear transmission structure, will rotate along with the driven shaft to convey the work. When the second driven rod rotates, it synchronously drives the cam to rotate. When the cam's convex point rotates and contacts the multi-group diverter seat, it will cause the diverter seat to vibrate, thereby promoting the rapid feeding of the diverter seat. At the same time, when sampling vegetables for testing, the operator can control the first and second electric telescopic rods to extend and retract synchronously, which can adjust the tilt direction of the diverter seat, i.e., the diversion direction, from the screening. Vegetables of different sizes, sorted out through the gaps in the cylinder, are guided into the hopper. The vegetables inside the hopper then fall into a storage bin. Simultaneously, the crushing rack, driven by a chain drive structure, rotates along the drive shaft and driven shaft. The rotating crushing rack drives the crushing blades to stir and crush the vegetables in the storage bin. The resulting juice is filtered through a screen and discharged through the outlet into a storage box containing a detection reagent. When the reagent changes color, it indicates the presence of pesticide residues on the vegetables. The specific pesticide residue level can also be detected using testing equipment. The detection process is convenient and quick. Compared to existing methods that spray pesticides onto the vegetable surface, the detection data from this application is more accurate. Furthermore, the aforementioned detection method can only detect pesticide residues on the vegetable surface and requires secondary washing after testing, making it cumbersome to operate.

[0020] This invention effectively solves the problem that existing crushing mechanisms for testing are prone to affecting the accuracy of test data due to internal residues by using a combined cleaning pipeline and monitoring probe. Driven by an external water supply device, the cleaning pipeline and cleaning hood can be used to wash vegetables and feed buckets respectively, thereby avoiding the influence of vegetable juice left from the previous test on subsequent test data due to residues inside the feed bucket, thus ensuring the accuracy of the test data. At the same time, it can enrich the functionality of the device. Staff can remotely and irregularly check the cleaning effect of the cleaning hood through the images captured by the monitoring probe, thereby improving the intelligence level of the device, realizing the purpose of remote control and monitoring, and further enriching the functionality of the device.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-6 This invention provides a technical solution: a sorting machine that facilitates pesticide residue detection.

[0030] Example 1

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a drive shaft 2 is provided inside the base 1, and a driven shaft 3 is provided on one side of the drive shaft 2. The drive shaft 2 is connected to the driven shaft 3 via a conveyor belt 4. The drive shaft 2 is connected to the driven mechanism 6 and the output end of the motor 7. A cleaning hood 8 is provided above the conveyor belt 4 and is fixedly connected to the top of the base 1. A screening cylinder 14 is provided on the side of the driven shaft 3 away from the drive shaft 2.

[0032] In a further embodiment, the conveyor belt 4 is provided with uniformly distributed mesh holes 5, and the conveyor belt 4 is disposed inside the base 1.

[0033] In a further embodiment, the cleaning hood 8 has an arc-shaped cross-section, and nozzles 12 are evenly distributed on the inner wall of the cleaning hood 8. At the same time, a monitoring probe 11 is provided at the center of the cleaning hood 8.

[0034] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the diversion seat 10 is located below one side of the screening cylinder 14, and a hopper 15 is provided on one side of the diversion seat 10. A cleaning pipe network 25 is connected to the hopper 15, and both the cleaning pipe network 25 and the cleaning hood 8 are connected to an external water supply device. A material barrel 16 is connected to the bottom of the hopper 15, and a crushing rack 19 is provided inside the material barrel 16. A crushing blade 20 is connected to the crushing rack 19, and a filter screen 21 is provided below the crushing blade 20. The filter screen 21 is fixedly installed inside the material barrel 16 and is rotatably connected to the crushing rack 19. A discharge port 22 is connected to the bottom of the material barrel 16, and a storage box 23 is provided below the discharge port 22. The storage box 23 is slidably connected to the bracket 24, and the bracket 24 is fixedly connected to the bottom of the material barrel 16. A cleaning door is rotatably connected to the front outer wall of the material barrel 16.

[0035] In a further embodiment, the diverter seat 10 and the screening cylinder 14 are alternately arranged inside the base 1, and the screening cylinders 14 are connected by a belt drive structure. Meanwhile, the width of the diverter seat 10 increases from left to right, the screening cylinder 14 is connected to the driven shaft 3 by a belt drive structure, and the spacing between the screening cylinders 14 increases from left to right.

[0036] In a further embodiment, the crushing rack 19 is connected to the drive shaft 17 via the chain drive structure 18, and the drive shaft 17 is fixedly connected to the outer wall of the base 1 via the fixed seat 13. At the same time, the drive shaft 17 is connected to the other end of the driven shaft 3 via the bevel gear drive structure 9.

[0037] Specifically, in actual operation, motor 7 drives the drive shaft 2 to rotate. The drive shaft 2 drives the driven shaft 3 and the driven mechanism 6 to rotate via the conveyor belt 4, thereby enabling the conveyor belt 4 to move the vegetables to the right into the cleaning hood 8. The staff can remotely check the cleaning quality inside the cleaning hood 8 by capturing images through the monitoring probe 11. Driven by the external water supply equipment, water will enter the cleaning hood 8 and be sprayed onto the vegetables passing through it through the multi-directionally distributed nozzles 12. At the same time, the driven mechanism 6 will promote the rotation of the vegetables to assist in cleaning. After cleaning, the vegetables will be moved to the screening cylinder 14 by the conveyor belt 4. The screening cylinder 14 will rotate to transport the vegetables with the help of the belt drive structure. During the movement, the vegetables will fall from the gap between the two sets of screening cylinders 14 onto different diversion seats 10 and be diverted to the appropriate storage device by the diversion seats 10.

[0038] When pesticide residue testing is required, staff can control the first electric telescopic rod 26 and the second electric telescopic rod 27 to extend and retract synchronously, thereby guiding the vegetables that have fallen onto the diversion seat 10 into the hopper 15. The vegetables that enter the hopper 15 will fall into the material barrel 16 through the bottom through hole. At the same time, the crushing frame 19 will rotate along the driven shaft 3 with the drive shaft 17 under the drive of the chain drive structure 18. The rotating crushing frame 19 will drive the crushing blades 20 to stir and crush the vegetables in the material barrel 16. The juice produced by crushing will be filtered through the filter screen 21 and discharged through the discharge port 22 into the storage box 23 containing the detection reagent. The storage box 23 can then be pulled out from the bracket 24 for testing.

[0039] Example 2

[0040] This embodiment is a further description of the above embodiments. It should be understood that this embodiment includes all the aforementioned technical features and is further described in detail.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, in a further embodiment, the driven mechanism 6 includes a first driven rod 601, a cam 602, a gear 603, and a second driven rod 604. The first driven rod 601 and the second driven rod 604 are both provided with cams 602, and the first driven rod 601 is connected to a gear 603.

[0042] In a further embodiment, the first driven rod 601 is evenly distributed between the drive shaft 2 and the driven shaft 3, and the first driven rod 601 is connected to the drive shaft 2 through a belt drive structure.

[0043] In a further embodiment, the first driven rods 601 are connected by a gear 603, and the rotation directions of two adjacent sets of first driven rods 601 are opposite.

[0044] In a further embodiment, the second driven rod 604 is disposed below the diverter seat 10, and the second driven rod 604 is connected to one end of the driven shaft 3 through the bevel gear transmission structure 9. Meanwhile, the diverter seat 10 is connected to the base 1 through the first electric telescopic rod 26 and the second electric telescopic rod 27.

[0045] In a further embodiment, the cam 602 on the second driven rod 604 and the cam 602 on the first driven rod 601 respectively contact the bottom of the conveyor belt 4 and the diverter seat 10.

[0046] Specifically, the first driven rod 601 and the second driven rod 604 rotate synchronously in cooperation with the belt drive structure and the bevel gear drive structure 9, respectively. The first driven rod 601 drives the cam 602 to rotate. When the cam 602's protrusion rotates to the bottom of the conveyor belt 4, it will lift the conveyor belt 4 upward. When the protrusion moves away from the bottom of the conveyor belt 4, the conveyor belt 4 moves downward and resets. This allows the vegetables on the conveyor belt 4 to rotate during the up-and-down movement, which facilitates the spray nozzles 12 on the cleaning hood 8 to spray and wash them in multiple directions. When the second driven rod 604 rotates, it synchronously drives the cam 602 to rotate. When the cam 602's protrusion rotates and contacts the multi-group diverter seat 10, it will cause the diverter seat 10 to vibrate, thereby promoting the rapid feeding of the diverter seat 10.

[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
