[0002] Field efficacy trials are tests that verify and evaluate the effectiveness of pesticides under actual field conditions in natural environments or artificially simulated natural environments. The purpose is to evaluate the control effects of pesticides in real environments and provide a scientific basis for pesticide registration, use and promotion.

[0003] During field efficacy tests, in order to ensure the safety of pesticide use, the pesticide residues in crops will be tested after the crops mature. Before the test, the agricultural products need to be crushed, and the crop solution needs to be extracted for sampling and testing. However, the existing extraction device can only extract one crop at a time during use. When it is necessary to extract multiple different types of crops, it takes a lot of time, resulting in low extraction efficiency, which is inconvenient for people to use. Utility Model Content

The top of the workbench is provided with a plurality of square grooves arranged corresponding to the crushing mechanisms, and a crushing barrel is placed in each of the plurality of square grooves.

[0007] As a further optimization solution of the present invention, the top inner wall of the working box is rotatably connected to a driving wheel, the outside of each of the multiple fixed columns is equipped with a driven wheel that engages with the driving wheel, and the top of the working box is equipped with a rotating motor that drives the driving wheel to rotate.

[0008] As a further optimization solution of the present invention, a mounting opening is provided at the bottom of the crushing cylinder, a filter screen is installed inside the mounting opening, and the bottom of the crushing cylinder is a square structure and is used in conjunction with a square groove.

[0009] As a further optimization solution of the present invention, the top of the base is provided with a plurality of placement grooves arranged corresponding to the square grooves, a material receiving barrel is placed inside the plurality of placement grooves, and a drainage pipe connected to the placement groove is installed at the bottom of the plurality of placement grooves.

[0010] As a further optimization solution of the present invention, a mounting hole is provided at the bottom of the fixing column, an internal thread is provided inside the mounting hole, and an external thread is provided at the end of the rotating rod for use with the internal thread.

[0011] As a further optimization solution of the present invention, a baffle is installed on the outside of the rotating rod, which is located above the multiple crushing knives and is used to seal the top of the crushing barrel.

DETAILED DESCRIPTION

[0020] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] like Figure 1 - Figure 6 As shown, a portable extraction device for field efficacy testing includes a base 1, a support column 2 installed on the top of the base 1, and a workbench 3 installed on the top of the support column 2. A pneumatic cylinder 4 is installed at the top center of the workbench 3, and a working box 5 is installed at the output end of the pneumatic cylinder 4. A plurality of crushing mechanisms are installed at the bottom of the working box 5. The crushing mechanisms include a fixed column 17 rotatably connected to the inner wall of the top of the working box 5 and extending to the bottom of the working box 5, a rotating rod 19 detachably installed at the bottom of the fixed column 17, and a plurality of crushing knives 7 installed on the outside of the rotating rod 19. The top inner wall of the working box 5 is rotatably connected to the driving wheel 13 , the outside of multiple fixed columns 17 are equipped with driven wheels 14 that mesh with the driving wheel 13, and the top of the working box 5 is equipped with a rotating motor 6 that drives the driving wheel 13 to rotate. The top of the workbench 3 is provided with multiple square grooves 12 corresponding to the crushing mechanism. Crushing barrels 8 are placed in the multiple square grooves 12. When the residue inside the crushing barrel 8 needs to be taken out, the crushing barrel 8 can be directly taken out from the square grooves 12, and it is convenient to clean the crushing barrel 8. The outside of the rotating rod 19 is equipped with a baffle 18 located above the multiple crushing knives 7 and used to block the top of the crushing barrel 8. When the crushing mechanism is fully moved to When the crushing drum 8 is inside, the baffle 18 will block the top of the crushing drum 8 to prevent the crushed particles from splashing out from the top of the crushing drum 18 during the crushing of crops. The top of the crushing drum 8 and the bottom of the baffle 18 are both provided with a sliding layer, thereby reducing the friction generated between the top of the crushing drum 8 and the bottom of the baffle 18, thereby extending the service life of the crushing drum 8 and the baffle 18. The bottom of the crushing drum 8 is provided with a mounting port 15, and a filter screen 16 is installed inside the mounting port 15. The bottom of the crushing drum 8 is a square structure and is used in conjunction with the square groove 12, so as to prevent the crushing mechanism from rotating and driving the crushing drum 8. The top of the base 1 is provided with a plurality of placement grooves 11 corresponding to the square grooves 12, and a material receiving barrel 10 is placed inside the plurality of placement grooves 11. The bottom of the plurality of placement grooves 11 is provided with a drainage pipe 9 connected with the placement groove 11. A mounting hole is provided at the bottom of the fixed column 17, and an internal thread is provided inside the mounting hole. An external thread used in conjunction with the internal thread is provided at the end of the rotating rod 19 and on the side close to the fixed column 17. When the crushing mechanism needs to be cleaned, the rotating rod 19 can be rotated and the rotating rod 19 can be unscrewed and removed from the inside of the mounting hole. At this time, the crushing knife 7 can be directly cleaned.

[0022] It should be noted that this portable extraction device for field efficacy tests, when in use, places different kinds of crops inside a plurality of crushing barrels 8, and then places the crushing barrels 8 into square grooves 12. When the crushing barrels 8 are placed in the plurality of placement grooves 12, the pneumatic cylinder 4 will drive the working box 5 to move downward. At this time, the plurality of crushing mechanisms will move into the plurality of crushing barrels 8, and then start the rotating motor 6. The rotating motor 6 will drive the driving wheel 13 to rotate. With the cooperation of the driving wheel 13 and the plurality of driven wheels 14, the plurality of fixed columns 17 will rotate. Driven by the fixed columns 17, the rotating rod 19 will drive the plurality of crushing knives 7 to rotate, thereby crushing the crops inside the crushing barrel 8. The juice produced after crushing will be filtered through the filter net 16. The filtered juice will enter the receiving barrel 10 through the drainage pipe 9, thereby completing the extraction of the juice.

[0023] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
