And the preferred implementation of the present application is given.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0026] The invention aims to solve the technical problem in the background art that it is too cumbersome and inefficient to use multiple devices when obtaining detection solutions for agricultural and food products.
[0027] Please see Figures 1 to 7 The following embodiment is provided to illustrate an integrated sampling device for detecting pesticide residues in agricultural and food products, comprising a support frame 1, a crushing component 2, an extrusion and filtering component 3, and a collection and drainage component 4, wherein:
[0028] The support frame 1 includes a fixed part 11 and a retractable part 12, the retractable part 12 is connected to the side wall of the crushing component 2, the upper end of the fixed part 11 is connected to the lower end of the retractable part 12, the extrusion filter component 3 is arranged at the upper end of the fixed part 11, the extrusion filter component 3 is located directly below the crushing component 2, and the outer diameter of the crushing component 2 is smaller than the inner diameter of the extrusion filter component 3, the collecting and drainage component 4 is detachably connected to the bottom of the extrusion filter component 3, the crushing component 2 can be raised and lowered between a first position and a second position, when the crushing component 2 is located in the first position, the crushing component 2 is located outside the extrusion filter component 3, when the crushing component 2 is located in the second position, the bottom of the crushing component 2 extends into the extrusion filter component 3 and is extruded and fitted, and the bottom of the crushing component 2 is an openable and closable structure facing the extrusion filter component 3.
[0029] Specifically, the support frame 1, the crushing component 2, the extrusion filter component 3 and the collection and drainage component 4 are sequentially connected according to the manufacturing process. The support frame 1 is symmetrically arranged on both sides of the crushing component 2, the extrusion filter component 3 and the collection and drainage component 4. The cross-sections of the crushing component 2 and the extrusion filter component 3 can be rectangular or circular. In the present embodiment, they are preferably cylindrical structures, and the outer diameter of the crushing component 2 is smaller than the inner diameter of the extrusion filter component 3, so that the crushing component 2 can extend into the extrusion filter component 3. When the crushing component 2 is in the first position, it can crush the agricultural and food products. After crushing, since the bottom of the crushing component 2 is set to an open-close structure, when the bottom of the crushing component 2 is opened, the crushed agricultural and food products can fall into the extrusion filter component 3, and then the bottom of the crushing component 2 is closed. Finally, the retractable part 12 drives the crushing component 2 to move from the first position to the second position. During this process, the bottom of the crushing component 2 is close to the bottom of the pressure filter component, and there is an extrusion force between the two, so that the crushed objects in the extrusion filter component 3 are squeezed and filtered, and the filtered juice is collected in the collection and drainage component 4.
[0030] When in use, when the crushing component 2 is in the first position, the openable and closable structure at the bottom of the crushing component 2 is in a closed state. First, agricultural and food products such as fruits and vegetables are placed in the crushing component 2 and crushed to the desired degree. Next, the openable and closable structure at the bottom of the crushing component 2 is opened, and the crushed objects in the crushing component 2 fall into the extrusion and filtering component 3. Then, the openable and closable structure at the bottom of the crushing component 2 is closed to close it. Next, the retractable part 12 drives the crushing component 2 to move downward. Since the outer diameter of the crushing component 2 is smaller than the inner diameter of the extrusion and filtering component 3, the crushing component 2 enters the extrusion and filtering component 3, and when the bottom of the crushing component 2 approaches the bottom of the extrusion and filtering component, the crushed objects in the extrusion and filtering component 3 are squeezed and filtered, and the filtered juice of fruits and vegetables is collected in the collection and drainage component 4.
[0031] When the device is used to obtain the detection solution of agricultural and food products, the crushing component 2 can not only crush the agricultural and food products, but also the crushed products can fall from the bottom of the crushing component 2 into the extrusion and filtration component 3, and the crushing component 2 and the extrusion and filtration component 3 can cooperate with each other for extrusion and filtration, which has a simple and convenient function. Compared with the prior art, there is no need to prepare crushing devices, extrusion devices, filtration devices, etc. separately. The device provided by the present application takes less time and can improve the efficiency of sampling.
[0032] In order to crush agricultural and food products, in some specific embodiments, the crushing assembly 2 includes a crushing barrel 21, an upper cover 22 and a rotating rod 222, the crushing barrel 21 is detachably connected to the upper cover 22, a first rotating drive part 221 is provided in the upper cover 22, one end of the rotating rod 222 is drivingly connected to the first rotating drive part 221, and a crushing blade 223 is provided on the rotating rod 222.
[0033] Specifically, the edge of the upper cover 22 has a downward protrusion, and the surface of the protrusion has a thread made of flexible material. When the upper cover 22 is covered on the crushing barrel 21, the protrusion fits tightly against the inner wall of the crushing barrel 21.
[0034] The first rotation driving unit 221 is used to drive the crushing blade 223 to rotate and crush the agricultural and food products in the crushing cylinder 21.
[0035] In some preferred embodiments, the openable and closable structure includes a second rotating drive unit 231 and an opening and closing plate 232, the second rotating drive unit 231 is arranged on the bottom end side of the crushing barrel 21, and the opening and closing plate 232 is connected to the power output shaft of the second rotating drive unit 231, and the second rotating drive unit 231 drives the opening and closing plate 232 to rotate between a third position and a fourth position. In the third position, the opening and closing plate 232 covers and seals the bottom end of the crushing barrel 21, and in the fourth position, the opening and closing plate 232 avoids the bottom end of the crushing barrel 21.
[0036] Among them, the second rotating drive part 231 is used to drive the opening and closing plate 232 to open and close. When the opening and closing plate 232 is in the third position, that is, when the crushing component 2 is crushing agricultural and food products or the crushed objects in the crushing component 2 fall into the extrusion and filtering component 3, the opening and closing plate 232 is closed; when the opening and closing plate 232 is in the fourth position, that is, after the crushing component 2 crushes agricultural and food products, the opening and closing plate 232 is opened, and the crushed objects in the crushing component 2 fall into the extrusion and filtering component 3.
[0037] The advantage of such an arrangement is that there is no need to transfer the crushed materials in the crushing component 2 to the extrusion and filtering component 3 for extrusion, which further improves the efficiency and is more convenient.
[0038] Furthermore, there are two openable and closable structures, which are symmetrically arranged on both sides of the crushing barrel 21, and the two opening and closing structures are opened and closed synchronously. When the two opening and closing plates 232 are both located at the third position, the two opening and closing plates 232 are spliced to cover and seal the bottom end of the crushing barrel 21.
[0039] The two opening and closing plates 232 are symmetrically arranged on both sides of the crushing cylinder 21. When the two opening and closing plates 232 are both located at the third position, that is, after the crushing cylinder 21 crushes the agricultural and food products or the agricultural and food products in the crushing cylinder 21 fall into the extrusion filtering component 3, at this time, the two opening and closing plates 232 are closed and cover the bottom of the crushing cylinder 21; when the crushing cylinder 21 crushes the agricultural and food products, the two opening and closing plates 232 are rotated outward from the bottom of the extrusion filtering cylinder to open, and the crushed products fall into the extrusion filtering component 3.
[0040] Two symmetrical opening and closing plates 232 are provided, which are two semicircles of the same size and shape in this embodiment. The advantage of such a configuration is that it is more stable when opening and closing, and the crushed objects in the crushing assembly 2 can fall out completely.
[0041] To prevent the opening and closing plate 232 from tilting upward when the crushing assembly 2 is in the second position, in some preferred embodiments, a rotation-stopping boss 211 is provided at the lower end of the inner wall of the crushing barrel 21, and the rotation-stopping boss 211 has an inclined surface, and in the direction from the upper end of the crushing barrel 21 to the lower end thereof, the inclined surface extends obliquely from the inner wall of the crushing barrel 21 toward the center of the crushing barrel 21, and the angle between the inclined surface and the inner wall of the crushing barrel 21 is 20° to 40°.
[0042] After the crushing barrel 21 crushes the agricultural and food products, the bottom of the crushing barrel 21 opens so that the crushed products fall into the extrusion and filtering assembly 3. After the crushed products fall, the bottom of the crushing barrel 21 closes. Next, the telescopic part 12 adjusts the crushing barrel 21 to move downward. There is a certain extrusion force between the bottom of the crushing barrel 21 and the bottom of the extrusion and filtering assembly 3, so the crushed products can be squeezed. Since the bottom of the crushing barrel 21 is composed of two parts, in this process, considering that during extrusion, the middle part of the bottom surface of the crushing barrel 21 will slightly tilt upward, resulting in insufficient extrusion, a rotation-stopping boss 211 is provided on the inner wall of the crushing barrel 21 to limit the upward tilting of the bottom surface of the crushing barrel 21 after being subjected to force.
[0043] In order to adjust the up and down movement of the crushing assembly 2. In this embodiment, the telescopic part 12 includes a third rotation driving part 121, a fixing plate 122 and a screw rod 123, wherein the third rotation driving part 121 is arranged at the upper end of the fixing part 11, the fixing plate 122 is arranged on the side wall of the crushing assembly 2, and the screw rod 123 is connected to the third rotation driving part 121 and is threadedly matched with the fixing plate 122.
[0044] There are two retractable parts 12, which are symmetrically arranged on both sides of the side wall of the crushing cylinder 21. The screw rod 123 and the fixing plate 122 are used in threaded cooperation, and the third rotation driving part 121 drives the screw rod 123 to rotate, and the fixing plate 122 threadedly cooperated with the screw rod 123 rises and falls, thereby driving the crushing assembly 2 to move between the first position and the second position.
[0045] In order to solve the problem in the prior art that it is too cumbersome to extrude the crushed object using a separate extrusion device, in this embodiment, the extrusion filter assembly 3 includes an extrusion cylinder 31, which is located below the crushing assembly 2 and fixedly connected to the upper end of the fixing portion 11, and the bottom of the extrusion cylinder 31 is set as a filter screen 32.
[0046] The cross-section of the extrusion cylinder 31 can be circular or rectangular, but it must correspond to the shape of the crushing component 2. In the present embodiment, it is preferred that the extrusion cylinder 31 is cylindrical, and the inner diameter of the extrusion cylinder 31 is larger than the outer diameter of the crushing component 2. The mesh size of the filter screen 32 is the minimum specification, which can be selected according to actual conditions. Furthermore, the filter screen 32 can also be set to a detachable structure, and filter screens 32 of different specifications can be selected for replacement according to actual conditions.
[0047] The filter net 32 can cooperate with the bottom of the crushing component 2 to squeeze the crushed objects, and during the squeezing process, the filter net 32 can also filter the juice of the agricultural and food products and collect it into the drainage component 4.
[0048] In some preferred embodiments, the collection and drainage component 4 includes a funnel 41 and a metering dropper 42 , the inlet end of the funnel 41 is detachably connected to the bottom of the extrusion filtration component 3 , and the outlet end of the funnel 41 is connected to the inlet end of the metering dropper 42 .
[0049] Specifically, the diameter of the inlet end of the funnel 41 is preferably larger than the outer diameter of the squeeze filter assembly 3, and the shapes are preferably the same. In this way, the agricultural product juice in the squeeze filter assembly 3 can be completely collected. In order to facilitate the subsequent use of the juice for pesticide residue detection, a metering dropper 42 is provided on the outlet end of the funnel 41.
[0050] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or substitutions within the technical scope disclosed by the present invention, and these modifications or substitutions should be included in the protection scope of the present invention.
