Further, the blocking mechanism 300 includes a first movable block 310, a first movable block 310 is installed at the top end inside the extension block 125, a blocking plate 311 is installed at one end of the first movable block 310, a sliding groove 312 is formed at one side of the blocking plate 311 close to the transportation crawler 112, a second sliding block 314 is installed at one side inside the first movable block 310 close to the first movable block 310, a sleeve rod 315 is installed at one side of the second sliding block 314, a connecting rod 317 is installed at one side of the sleeve rod 315 close to the blocking plate 311 in a sleeved manner, a sleeve spring 316 is installed inside the sleeve rod 315, one end of the sleeve spring 316 is connected with the connecting rod 317, a movable block 313 is installed at one end of the connecting rod 317 far away from the sleeve spring 316, the movable block 313 extends into the sliding groove 312, a filter screen 318 is installed at one side of the extension block 125 close to the water suction pipe 122 in an inserted manner, and the blocking plate 311 installed at the water outlet of the casing 110 will prevent the water flow inside the extension block 125 from flowing back, thereby lead to inside dust of extension piece 125 will be inside along with rivers backward flow to casing 110, thereby lead to inside there being the dust in the inside water of casing 110, thereby lead to inside unable the condition emergence carrying out effectual cleanness to the seed that the staff put into of casing 110, and install the inside filter screen 318 of fixed block 125, then can be when water pump 121 comes the inside rivers of casing 110 to extract through water pump 122, carry out effectual clearance to the impurity in the aquatic, thereby it does not have impurity in the spun rivers in the sprinkler bead 124 afterwards to prevent, thereby make the clean efficiency of the inside seed of casing 110 obtain improving.

Further, the collecting mechanism 400 includes an auxiliary pipe 410, the auxiliary pipe 410 is installed at the bottom end of the extension block 125, insertion grooves 412 are all opened at two ends of the inside of the auxiliary pipe 410, insertion blocks 413 are slidably installed inside the insertion grooves 412, a collecting box 411 is installed between the two insertion blocks 413, after water flows enter the extension block 125, the installed filter screen 318 inside the extension block 125 can effectively block impurities in the water flows, and the impurities in the water can stay in the fixing block 125 due to the blocking mechanism and gradually settle in the collecting box 411, so that workers can clean the impurities in the collecting box 411 conveniently, the whole water flows inside the shell 110 can be kept clean, and the cleaning efficiency of the seeds poured into the shell 110 by the workers is improved by the clean water flows inside the shell 110.

The working principle is as follows: when cleaning seeds of melons and fruits, a worker pours the seeds from an auxiliary blanking block 127 arranged on the shell 110 into the shell 110, then pours the seeds into a cleaning solution for cleaning the seeds into the shell 110, then starts the device body 100 to start the water pump 121, so that the water pump 121 pumps cleaning water in the shell 110 through the water pumping pipe 122, and then the water pump 121 sprays the water pumped from the shell 110 into the shell 110 through the water outlet pipe 123 from the water spray head 124, so that the water flow in the shell 110 can be recycled, the seeds deposited at the bottom end of the shell 110 are washed by the water flow sprayed from the water spray head 124, and the water sprayed from the water spray head 124 is too large when the deposited seeds are cleaned by the water spray head 124, the seeds are moved towards the transportation track 112, and then the worker rotates the rotation motor 116 to rotate the transportation track 112, so as to transport the seeds inside the housing 110 by the transportation track 112, the mounting block 117 mounted on the outer surface of the transportation track 112 effectively limits the position of the seeds which are flushed onto the transportation track 112 by the water spray head 124 during the transportation of the seeds by the transportation track 112, so as to prevent the seeds from slipping off the transportation track 112 during the transportation of the seeds by the transportation track 112 which is mounted obliquely, the friction roller 111 mounted in front of the transportation track 112 further transports the seeds transported on the transportation track 112, and the storage box 128 disposed on the extension block 125 recovers the seeds transported from the friction roller 111, thereby facilitating the use of the staff afterwards.

The filter screen 318 installed inside the extension block 125 will effectively filter the cleaning liquid to be reused when the water pump 121 pumps the water flow inside the housing 110 through the transportation crawler 112, and during the water flow pumped by the pumping pipe 122, the blocking plate 311 installed inside the extension block 125 will be moved to one side by the pumping pipe 122, so that the water flow inside the housing 110 can enter the inside of the extension block 125, and when the blocking plate 311 is opened by the transportation crawler 112, the auxiliary blocking plate 311 installed at one side of the blocking plate 311 will limit the opened blocking plate 311 during the starting process of the blocking plate 311, so as to avoid the backflow inside the extension block 125, so as to ensure that the water flow with impurities inside the housing 110 will stay inside the extension block 125, and thus the water flow with certain impurities inside the extension block 125, after a certain time of precipitation inside the extension block 125, impurities in the water are finally precipitated in the collection box 411 installed at the bottom end of the extension block 125, thereby facilitating the effective recovery of the impurities in the water flow inside the housing 110 by the staff.

When the worker pours the seeds into the shell 110, the seeds with better quality can be deposited at the bottom end of the shell 110 and then sprayed onto the transportation crawler 112 by the water spraying head 124, the bad seeds poured into the shell 110 can be lighter due to the damage of the seeds and float on the surface of the cleaning solution, and the accommodating mechanism 200 arranged between the installation rods 114 of the worker can enable the water flow inside the shell 110 to circulate when the worker starts the water pump 121, so that the floating bad seeds on the shell 110 can enter the accommodating net 212.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
