DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figures 1 to 8The present invention provides a technical solution: an agricultural product pesticide residue detection device, comprising a bottom plate 1, a crushing barrel 2 is fixedly installed on the top of the bottom plate 1, a cleaning barrel 3 is fixedly installed on the top of the crushing barrel 2, a first arc-shaped cover that can be vertically moved and adjusted is installed inside the cleaning barrel 3, the first arc-shaped cover is composed of two cleaning covers 6 that can be rotated to open or close, and a plurality of cleaning nozzles 11 connected to an external water supply part are installed on the inner wall of the cleaning cover 6, a second arc-shaped cover that can be vertically moved and adjusted is installed inside the crushing barrel 2, the second arc-shaped cover is composed of two crushing covers 7 that can be rotated to open or close, and both the cleaning cover 6 and the crushing cover 7 are in the shape of a quarter sphere; When the openings of the first arc-shaped cover and the second arc-shaped cover face each other, the two together form a cleaning chamber; When the first arc-shaped cover is embedded in the second arc-shaped cover, the two together form a crushing chamber.

[0021] See also Figure 2 as well as Figure 4 When the device is used, the openings of the cleaning cover 6 and the crushing cover 7 are directed upwards through the driving part (this is the first state), the cover on the top of the crushing barrel 2 is opened, the crops to be detected are placed in the first arc-shaped cover formed by the two cleaning covers 6, and the cover is reset to prevent water splashing during the subsequent cleaning process, the external water supply component is started, and the water flows through the cleaning nozzle 11 to clean the crops, and preliminarily clean the pesticides adhering to the surface of the crops. When the flushing reaches the preset time, the two cleaning covers 6 are relatively rotated and opened (this is the second state), so that the crops fall into the crushing cover 7, and the crops in the crushing cover 7 continue to be cleaned by the cleaning nozzle 11. When the crops are in the cleaning cover 6, the cleaning nozzle 11 is below the crops, and the bottom of the crops can be cleaned. When the crops fall into the crushing cover 7, since the two cleaning covers 6 are flipped upwards, the cleaning nozzle 11 is above the crops, thereby The top of the crops is cleaned, and then all aspects of the crops are cleaned. At this time, the external water supply component stops supplying water, and the two cleaning covers 6 rotate to return to the initial state, so that the arc surface faces downward, and the cleaning cover 6 is driven downward by the external driving part, and at the same time, the crushing cover 7 keeps the existing state and moves upward, so that the cleaning cover 6 enters the crushing cover 7 (this is the third state), thereby squeezing the crops to complete the purpose of crushing them. The crops are squeezed and crushed by the reciprocating movement of the cleaning cover 6 and the crushing cover 7. The crushed crops and the juice of the crops remain in the crushing cover 7. The subsequent staff will take out the crushing cover 7 and perform pesticide detection on the juice through existing means, such as using biological materials (such as antibodies, enzymes) to react specifically with pesticides, and detecting the reaction signals through sensors to achieve rapid and sensitive detection to ensure that agricultural products meet safety standards before consumption, avoid consumers from ingesting harmful substances, and protect public health.

[0022] In this way, through the mutual cooperation between the two cleaning covers 6 and the two crushing covers 7, the cleaning nozzle 11 in the cleaning cover 6 cleans the pesticide residues on the surface of the crops to ensure that the internal pesticide residues are not affected by the surface residues when testing, avoid external pesticides interfering with the test results, and ensure accurate internal residue data, thereby more truly reflecting the pesticide content inside the crops, more accurately evaluating the permeability and migration behavior of pesticides in crops, and helping to study the distribution law of pesticides inside crops.

[0023] Among them, it is worth noting that when the device is in the second state to clean the top of the crops, the two crushing covers 7 are in an open state and will not allow the crops therein to fall, so as to prevent the pesticides washed on the surface of the crops from accumulating inside the crushing covers 7, and in the process of the cleaning nozzle 11 cleaning the top of the crops, the inside of the crushing cover 7 will be continuously cleaned to prevent the pesticides from adhering to the inner wall of the crushing cover 7. When the cleaning is completed and switched to the third state, the two crushing covers 7 will be closed again to prevent the loss of the crushed juice. This can avoid the mixing of the crushed juice with the pesticides remaining on the surface of the crops, affecting the detection results, and can more accurately evaluate the internal pesticide residue level and better evaluate whether the pesticides have penetrated into the crops, which is very important for understanding the migration characteristics of pesticides and their effects on plant tissues.

[0024] Furthermore, a first gear 8 is integrally formed on the outer wall of the cleaning cover 6, a second rack 5 that can mesh with the first gear 8 is installed on the inner wall of the cleaning barrel 3, a second gear 9 is integrally formed on the outer wall of the crushing cover 7, and a first rack 4 that can mesh with the second gear 9 is fixedly connected to the inner wall of the crushing barrel 2.

[0025] See also Figure 4 At this time, it is the initial state (i.e., the first state), and the bottom of the crop is cleaned by the cleaning nozzle 11. After the cleaning time is set, the external driving unit drives the cleaning cover 6 to move downward. Under the cooperation of the first gear 8 and the cleaning cover 6, the two cleaning covers 6 move downward and flip upward at the same time (to switch to the second state, which can be specifically referred to in FIG. Figure 7 ), and then the crops inside the cleaning cover 6 fall into the crushing cover 7, so that the cleaning cover 6 and the crushing cover 7 directly form a cleaning chamber. At this time, the two crushing covers 7 are moved downward by the driving part to adjust a distance, and under the cooperation of the second gear 9 and the first rack 4, the bottom of the second arc cover is opened to form a water leakage channel, so that the cleaning nozzle 11 inside the cleaning cover 6 after flipping cleans the top of the crops, and at the same time cleans the inside of the crushing cover 7, so as to provide a basis for the subsequent crushing link.

[0026] When cleaning is finished, the external water supply unit stops supplying water, and the two cleaning covers 6 are driven by the external structure to continue to move downward, and the two crushing covers 7 are moved upward to close. When the cleaning covers 6 continue to move downward until the first gear 8 is disengaged from the second rack 5, the two cleaning covers 6 have no supporting force and will rotate under the action of gravity, so that the two cleaning covers 6 are reunited from below and form a crushing chamber with the crushing cover 7. The two crushing covers 7 are driven upward by the external driving unit until the second gear 9 is disengaged from the first rack 4, so that the cleaning covers 6 enter the inside of the crushing cover 7 (i.e. the third state, which can be specifically referred to in Figure 8 ), by adjusting the crushing cover 7 to reciprocate up and down, the crops inside the crushing cover 7 are continuously squeezed by the cleaning cover 6 and the crushing cover 7.

[0027] It is worth mentioning that when the crops are crushed in the third state, the first gear 8 on the outer wall of the cleaning cover 6 will increase the contact surface and the bite force, so that a more uniform and powerful force is applied to the crops, thereby improving the crushing efficiency and helping to crush the crops into smaller and more uniform particles, which is beneficial to the subsequent juice extraction and pesticide residue detection.

[0028] Furthermore, two slide grooves 13 are symmetrically provided on the inner wall of the cleaning barrel 3, and electric sliders 14 are slidably installed on the inner walls of the two slide grooves 13, and first central shafts 15 are fixedly installed on the outer walls of the two electric sliders 14, and the two cleaning covers 6 are rotatably installed on the outer walls of the two first central shafts 15 through the rotating ring 24; A lifting frame 18 is slidably installed inside the crushing barrel 2, and the second central axis 16 is fixedly installed on the inner walls on both sides of the lifting frame 18. The two crushing covers 7 are rotatably installed on the outer walls of the two second central axes 16. A cylinder 20 is fixedly installed at the bottom of the crushing barrel 2, and the output shaft of the cylinder 20 is fixedly connected to the bottom of the lifting frame 18.

[0029] See also Figure 2 , Figure 3 as well as Figure 6When the cleaning cover 6 needs to be moved, the electric slider 14 is driven up and down by an external power supply to achieve the purpose of adjusting the cleaning cover 6 up and down. When it is converted from the first state to the second state, the electric slider 14 slides downward in the slide groove 13, thereby driving the cleaning cover 6 to move downward. Under the cooperation of the first gear 8 and the second rack 5, the two cleaning covers 6 will rotate about the axis of the first central axis 15, and at the same time, the output shaft is retracted by the lifting frame 18, so that the bottom of the crushing cover 7 is opened to form a water leakage channel, thereby completing the state switching; when switching from the second state to the third state, the electric slider 14 is driven to continue to move downward, so that the first gear 8 is disengaged from the second rack 5, and the two cleaning covers 6 will be closed again under the action of gravity. At the same time, the lifting frame 18 is driven to extend by the cylinder 20, so that the two crushing covers 7 are completely closed, the second gear 9 is disengaged from the first rack 4, and the cleaning cover 6 enters the crushing cover 7, and the crushing cover 7 is driven to move up and down reciprocatingly by the cylinder 20, so as to achieve the purpose of crushing the crops inside the crushing cover 7.

[0030] Furthermore, a driven gear 19 is rotatably mounted at the bottom of the crushing barrel 2, and the driven gear 19 is slidably connected to the output shaft of the cylinder 20 via a flat key. A rotatable transmission gear 21 is mounted at the bottom of the crushing barrel 2, and the transmission gear 21 is meshed with the driven gear 19. A rotating ring 23 that can be rotatably adjusted is installed on the inner wall of the cleaning barrel 3 , and the two second racks 5 are fixedly installed on the inner wall of the rotating ring 23 .

[0031] As can be seen from the above, in the third state, the cleaning cover 6 and the crushing cover 7 simultaneously form a crushing chamber, and the output shaft is driven by the cylinder 20 to extend and retract to drive the crushing cover 7 to move up and down to complete the crushing of the crops. On this basis, the transmission gear 21 is driven by the motor fixed at the bottom of the crushing barrel 2 to rotate, thereby driving the driven gear 19 to rotate, and then driving the driven gear 19 to rotate, that is, the crushing cover 7 can continue to rotate while driving the crops therein to move up and down for crushing. By moving up and down and rotating at the same time, it can ensure that the crops are subjected to uniform force in different directions, making the crushing more uniform and avoiding insufficient crushing of some areas. In the process, the first gear 8 can be brought into contact with different parts of the crops, and can act more efficiently on various parts of the crops, thereby accelerating the crushing speed and improving the crushing efficiency.

[0032] When the crushing work is completed, the second rack 5 is disengaged from the first gear 8 by driving the rotating ring 23 to rotate (specifically, it can be driven by a motor, not shown in the figure), so that the electric slider 14 is driven to move upward to complete the resetting of the cleaning cover 6. In this process, water can be supplied through the external water supply part to clean the inside of the cleaning cover 6. When the cleaning cover 6 moves to the initial position, the second rack 5 is rotated to the initial position by driving the rotating ring 23 to rotate, so as to facilitate the next cleaning and crushing.

[0033] Furthermore, a cleaning liner 10 is fixedly installed on the inner wall of the cleaning hood 6, and a plurality of circular holes for the cleaning nozzle 11 to spray water are opened on the outer wall of the cleaning liner 10, a cavity connected with the cleaning nozzle 11 is provided inside the cleaning hood 6, an annular groove is opened on the inner wall of the rotating circle 24, and the annular groove is connected with the internal cavity of the cleaning hood 6, and a water inlet pipe 12 that can connect the external water supply part with the rotating circle 24 is installed inside the first central axis 15.

[0034] See also Figure 3 as well as Figure 7 When the cleaning cover 6 and the crushing cover 7 are in the second state, the two together form a cleaning chamber, and the external water supply part sends water into the internal cavity of the cleaning cover 6 through the water inlet pipe 12, so that the water is discharged from the cleaning nozzle 11, so as to facilitate the above-mentioned process of cleaning crops.

[0035] It is worth noting that an annular groove is provided on the inner wall of the rotating circle 24 to ensure that when the cleaning cover 6 rotates, water can still stably enter the cavity inside the cleaning cover 6 to ensure that the surface of the crops can be stably cleaned in both the first state and the second state.

[0036] It is worth mentioning that a cleaning liner 10 is installed in the cleaning cover 6. On the basis of the above-mentioned second state cleaning process, further improvements are made. In the second state, the top of the crop is sprayed and cleaned by the cleaning nozzle 11 in the initial stage. At this time, the bottom of the crushing cover 7 is in an open state. After cleaning for a period of time, the two crushing covers 7 are closed by the cylinder 20, that is, all the water sprayed by the cleaning nozzle 11 falls into the crushing cover 7. When the water inside the crushing cover 7 accumulates to a certain extent, the crops in the crushing cover 7 will float upward. At this time, the top of the crop can contact the cleaning liner 10, and the crushing cover 7 can be driven to rotate by the motor to wipe the crops in all aspects, thereby further cleaning the surface of the crops, and as Figure 7 As shown by the middle dotted line, the height of the cleaning liner 10 can be increased so as to make it easier to contact with the crops.

[0037] Furthermore, a heating module 17 is installed inside the crushing cover 7 , and a drying cover 25 is fixedly installed on the top of the crushing cover 7 .

[0038] When the second state is switched to the third state after cleaning the surface of the crops, the crops inside the crushing cover 7 are first heated and dried by the heating module 17, which can remove moisture from the surface of the crops, avoid excessive wetness during the crushing process, and improve the crushing efficiency. In addition, for subsequent pesticide residue detection, the drying process can reduce the interference of moisture on the detection results, making the detection more accurate.

[0039] It is worth mentioning that by providing the drying hood 25, the drying hood 25, the crushing hood 7 and the cleaning hood 6 can surround the crops together during drying to prevent heat dissipation, thereby increasing the drying rate.

[0040] Furthermore, magnets are fixedly connected to the closed bottom ends of the cleaning cover 6 and the crushing cover 7.

[0041] The magnets provided at the closed bottom of the cleaning cover 6 and the crushing cover 7 can increase the stability during the third stage of crushing and prevent the two from opening during the crushing process to affect subsequent work.

[0042] Furthermore, a water outlet 22 connected to an external water outlet pipe is provided on the inner wall below the crushing barrel 2.

[0043] The cleaned sewage can enter the water outlet pipe from the water outlet 22 and be discharged through the water outlet pipe, thereby preventing the sewage from continuously accumulating in the crushing barrel 2.

[0044] Furthermore, the cleaning liner 10 is made of silicone material, and the surface is configured as a wiping surface.

[0045] Silicone is soft and has a certain degree of elasticity, so it will not scratch the surface of crops. Silicone is also non-absorbent and will not absorb too much water during the cleaning process, thus maintaining the cleaning effect.

[0046] Furthermore, the crushing barrel 2 is detachable.

[0047] When the crops in the crushing cover 7 are crushed in the third stage, the crushing barrel 2 can be opened, and the crushing cover 7 can be completely taken out from the inside. The juice in the crushing cover 7 can be tested by a subsequent detection device to determine the pesticide residues in the crops.

[0048] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
