[0035] As described above, when the crops are crushed and juiced, the cutter 7 can be moved up and down while rotating, so as to achieve comprehensive crushing of the crops inside the barrel body 1. In addition, when the bracket 3 is taken out just after the crushing and juicing is completed, the mixed juice inside the barrel body 1 can be automatically sampled, which is convenient and quick.

[0036] Please see attached Figure 1 -Attached Figure 8In a preferred embodiment, the crushing assembly includes: a sleeve 6, which is slidably sleeved on the surface of the hollow column 5 through a spline, and a plurality of evenly distributed cutters 7 are fixed on the opposite surfaces of the outside of the sleeve 6. Two vertically symmetrically arranged first spring rods 16 are also fixed on the surface of the sleeve 6, and a sleeve block 18 is fixedly installed at the end of the telescopic end of each first spring rod 16. A rotating shaft 17 is rotatably installed on the sleeve block 18, and a round roller 8 is fixedly installed at the end of the rotating shaft 17 away from the hollow column 5. The fixed end and the telescopic end of the first spring rod 16 are slidably connected through a spline, and vertical grooves 20 that penetrate into the interior of the hollow column 5 are opened on the opposite sides of the hollow column 5, and the two vertical grooves 20 are both located inside the sleeve 6.

The telescopic end of the third spring rod is fixedly installed at the end of the rotating rod 12. The third spring rod and the corrugated ring 14 cooperate to make the rotating rod 12 reciprocate up and down. The opposite sides of the rotating rod 12 are fixedly installed with connecting plates 19. The two ends of the two connecting plates 19 that are far away pass through the two vertical grooves 20 respectively, and the ends of the two connecting plates 19 that are far away are fixedly installed on the inner wall of the sliding sleeve 6. The top of the rotating rod 12 passes through the top of the hollow column 5, and the top of the rotating rod 12 is fixedly installed with an L-shaped plate 13. The end of the vertical side of the L-shaped plate 13 is provided with a groove. A corrugated ring 14 is horizontally arranged above the bracket 3. When the vertical side of the L-shaped plate 13 contacts the corrugated ring 14, the vertical side of the L-shaped plate 13 slides between the corrugated ring 14. Two fixing frames 15 are fixedly installed at the bottom of the corrugated ring 14. The ends of the two fixing frames 15 are fixedly installed on the top of the bracket 3.

[0037] Specifically, the rotation of the hollow column 5 drives the sliding sleeve 6 and the partition plate 21 to rotate, and the rotation of the sliding sleeve 6 drives the cutter 7, the first spring rod 16 and the round roller 8 to rotate, so as to achieve the crushing and juicing of the crops.

[0038] Please see attached Figure 1 -Attached Figure 8 In a preferred embodiment, the sampling assembly includes: a second spring rod 23, the second spring rod 23 is vertically fixedly installed at the bottom center of the partition plate 21, the fixed end and the telescopic end of the second spring rod 23 are slidably connected by a spline, a sampling barrel 22 is fixedly installed at the bottom of the telescopic end of the second spring rod 23, the sampling barrel 22 slides between the inner wall of the hollow column 5, a piston disc 25 is slidably installed inside the sampling barrel 22, a connecting rod 24 is vertically fixedly installed at the bottom of the partition plate 21, the end of the connecting rod 24 passes through the top of the sampling barrel 22, and the end of the connecting rod 24 is fixedly installed on the top of the piston disc 25, a push rod 26 is vertically fixedly installed at the bottom center of the sampling barrel 22, a discharge pipe 27 and a feed pipe 28 are connected and installed at the bottom of the sampling barrel 22, and a first one-way valve and a second one-way valve are installed on the discharge pipe 27 and the feed pipe 28 respectively;

[0039] Preferably, the first one-way valve on the discharge pipe 27 can be closed and the second one-way valve on the feed pipe 28 can be opened, so that the juice inside the barrel body 1 will enter the sampling barrel 22 from the feed pipe 28, thereby completing the sampling of the crops just after juicing.

[0040] Please refer to the attached Figure 1 -Attached Figure 3 In a preferred embodiment, the driving assembly includes: a first pulley 10, the first pulley 10 is fixedly sleeved on the top of the surface of the hollow column 5, a driving motor is vertically installed on the top of the bracket 3, a second pulley 11 is fixedly installed on the output end of the driving motor, and a belt 9 is sleeved on the surface of the first pulley 10 and the second pulley 11;

[0041] Furthermore, the driving motor is used to drive the hollow column 5 to rotate, so as to achieve the crushing and sampling of crops.

[0042] The working principle of the present invention is as follows: first, the bracket 3 is installed on the barrel body 1, and the claw is installed inside the card slot 4 during installation. It should be noted that when the top rod 26 contacts the bottom of the barrel body 1, the sampling barrel 22 does not move, and the hollow column 5 continues to move downward, which will cause the sampling barrel 22 to enter the hollow column 5 and cause the second spring rod 23 to generate elastic force. The hollow column 5 continues to move to drive the partition plate 21, the connecting rod 24 and the piston plate 25 to move downward. At this time, the first one-way valve on the discharge pipe 27 is opened, and the second one-way valve on the feed pipe 28 is closed to discharge the gas inside the sampling barrel 22. When the round roller 8 contacts the bottom of the barrel body 1, the first spring rod 16 generates elastic force, so that the round roller 8 and the bottom of the barrel body 1 have a certain friction force to assist the round roller 8 to rotate, and then the crops to be tested are added to the barrel body 1.

[0043] Then, the driving motor is started to drive the second pulley 11 to rotate, the second pulley 11 rotates to drive the belt 9 to rotate, the belt 9 rotates to drive the first pulley 10 to rotate, the first pulley 10 rotates to drive the hollow column 5 to rotate, the hollow column 5 rotates to drive the sliding sleeve 6 and the partition plate 21 to rotate, the sliding sleeve 6 rotates to drive the cutter 7, the first spring rod 16 and the round roller 8 to rotate, so as to achieve the crushing and juicing of the crops, and the sliding sleeve 6 and the partition plate 21 rotate to drive the connecting plate 19, the connecting rod 24, the second spring rod 23 and the third spring rod to rotate, and the connecting plate 19 The rotation of the third spring rod drives the rotating rod 12 to rotate, and the rotation of the rotating rod 12 drives the L-shaped plate 13 to rotate. Due to the setting of the corrugated ring 14, the L-shaped plate 13 will reciprocate up and down while rotating. The up and down movement of the L-shaped plate 13 drives the rotating rod 12 to move up and down. The up and down movement of the rotating rod 12 drives the connecting plate 19 to move up and down. The up and down movement of the connecting plate 19 drives the sliding sleeve 6 and the cutter 7 to move up and down, so as to achieve comprehensive crushing of the crops inside the barrel body 1, and avoid the situation that the crops in the gaps between the cutters 7 cannot be completely crushed.

[0044] When the crops inside the barrel body 1 are crushed and juiced, it is necessary to remove the cutter 7, the round roller 8 and other parts for cleaning. When the bracket 3 moves upward, it will drive the hollow column 5 to move upward, and the elastic force generated by the second spring rod 23 will keep the sampling barrel 22 and its connecting parts in place when the hollow column 5 initially moves. In addition, the upward movement of the hollow column 5 drives the partition plate 21 to move upward, the upward movement of the partition plate 21 drives the connecting rod 24 to move upward, and the upward movement of the connecting rod 24 drives the piston plate 25 to move upward. Thereby, the first one-way valve on the discharge pipe 27 can be closed and the second one-way valve on the feed pipe 28 can be opened, and the juice inside the barrel body 1 will enter the sampling barrel 22 from the feed pipe 28, thereby completing the sampling of the crops just after juicing, ensuring the accuracy and convenience of sampling. Finally, the bracket 3 and its connecting parts are separated from the barrel body 1, and the push rod 26 is pressed to make the sampling barrel 22 enter the hollow column 5 to release the sampled juice for testing, which is convenient and quick, thereby improving the use effect of the equipment.

[0045] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
