Optionally, the tail removing machine comprises an anti-blocking device, the anti-blocking device comprises two first steel brush rolls 40 arranged in parallel with the rotary screen 10, the first steel brush rolls 40 are rotatably connected between the two upright posts 6 on the two sides of the frame 5, steel brushes are uniformly arranged on the first steel brush rolls 40, the end parts of the steel brushes are in abutting connection with the rotary screen 10 close to the first steel brush rolls, the sieve pores of the rotary screen 10 on the two outer sides can be cleaned conveniently by arranging the first steel brush rolls 40, so that the spiral shells in the sieve pores are pushed back into the rotary screen 10 by the steel brushes, the sieve pores of the rotary screen 10 are vacant to carry out the tail removing operation of the next round, the phenomenon that the sieve pores are blocked is reduced, and the smooth tail removing operation is ensured; still rotate between fixing base 35 and the last horizontal pole 7 and be connected with second steel brush roll 41, second steel brush roll 41 also with drum sieve 10 parallel arrangement, second steel brush roll 41 is located the top of first cutter 36, the tip of also fixedly connected with steel brush and steel brush on the second steel brush roll 41 is contradicted with the drum sieve 10 that is located in the middle and is connected, second steel brush roll 41 is all installed to drum sieve 10 both sides that are located in the middle, second steel brush roll 41 is to the sieve mesh on the drum sieve 10 that is located in the middle of clearing up the operation, prevent that the sieve mesh from appearing blockking up, guarantee going on smoothly of the operation of removing the tail.

Optionally, the tail removing machine further comprises a tail collecting device, the tail collecting device comprises a collecting frame 42 installed at the bottom of the box body 1, the collecting frame 42 is placed on the end portion of the bottom of the box body 1, and handles are fixedly connected to the outer side walls of the two ends of the collecting frame 42. Correspondingly, the lower parts of the two side plates of the box body are provided with openings matched with the collecting frame 42, so that the collecting frame 42 can be conveniently moved out of the box body. The feeding box 12 is located above the rotating shaft 9, the feeding box 12 is obliquely arranged, the lower end of the feeding box 12 faces the rotary screen 10, the lower end of the feeding box 12 is arranged in an open mode, spiral shells in the feeding box 12 can conveniently fall into the corresponding rotary screen 10, a supporting plate is fixedly connected to the bottom of the feeding box 12 in a communicating mode, and the supporting plate 44 is fixedly connected to the lower cross rod 8.

The using method comprises the following steps: by starting the driving motor 30 and the variable speed motor 22, the output shaft of the variable speed motor 22 drives the eccentric wheel 23 to rotate, the eccentric wheel 23 drives the transmission rod 24 to eccentrically rotate, so that the separation box 15 is driven to vibrate by the connecting rod 25, and the driving motor 30 drives the three rotating shafts 9 to rotate by the first belt 31, the second belt 32 and the third belt 33, so that the rotation of the rotary screen 10 is realized; spiral shells to be subjected to tail removal are added into a feed hopper 13, then the spiral shells reach a sorting plate 16 through the feed hopper 13, under the vibration of a sorting box 15, the spiral shells fall from different positions of sorting holes 17 to enter corresponding cavities according to the sizes of the spiral shells, so that the size classification of the spiral shells is realized, the sorted spiral shells enter corresponding feed boxes 12 through material collecting boxes 21 and are screened into corresponding rotary screens 10, the rotary screens 10 enable the tail portions of the spiral shells to be clamped into the screen holes in the rotating process, the first cutters 36 perform cutting and tail removal operation on the tail portions of the spiral shells leaking outside the rotary screens 10, the second cutters 39 perform secondary cutting operation on the tail portions of the spiral shells, the occurrence of the missing cutting phenomenon is reduced, and the tail removal efficiency is improved; the snail subjected to tail removing operation is subjected to mesh cleaning operation under the action of the steel brushes on the first steel brush roll 40 or the second steel brush roll 41, so that the blockage of meshes is reduced; and the tail part of the spiral shell cut off by the first cutter 36 or the second cutter 39 falls into the collection frame 42.

The above embodiments are not intended to limit the shape, material, structure, etc. of the present invention in any way, and any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention are within the scope of the technical solution of the present invention.
