The material distribution opening mechanism 2 includes a notched roller 21, a first bearing seat 22, a connecting bearing 23, a protruding sawtooth 24 and a material distribution guide 25. The material distribution guide 25 is arranged at intervals at the discharge position at the bottom of the feed hopper 1. The top of the material distribution guide 25 and the contact part with the water chestnut are wedge-shaped structures, which can divert the disordered water chestnuts into a specified movement path for movement;

The frame 5 includes an opening bracket 51, a shell breaking bracket 52, a material receiving bracket 53 and a column 54; the opening bracket 51, the shell breaking bracket 52, and the material receiving bracket 53 are respectively arranged along the height direction of the column 54, that is, the opening bracket 51 is arranged at the top position of the column 54; the shell breaking bracket 52 and the material receiving bracket 53 are respectively arranged in sequence below the opening bracket 51, and the column 54 provides support for the whole.

The feed hopper 1 is provided with a stabilizing frame, through which the feed hopper 1 is fixedly connected to the opening bracket 51 to ensure the stability of the feed hopper 1.

The connecting bearings 23 are respectively arranged at the two end positions of the notching roller 21, and the first bearing seats 22 are respectively arranged on the opening bracket 51. The opening bracket 51 is provided with an oblong hole. The left and right positions of the first bearing seats 22 are adjusted through the oblong hole, thereby adjusting the distance between the notching roller 21 and the bottom side wall of the feed hopper 1, thereby realizing the opening operation for water chestnuts of different sizes.

The raised serrations 24 are arranged along the circumference of the notching roller 21 to form a raised toothed ring, which is staggered with the material dividing guide 25. When the material dividing guide 25 divides the water chestnuts, the water chestnuts fall into the area where the raised toothed rings are located. The raised toothed rings are driven by an external motor to open the water chestnuts. Then, by adjusting the position of the first bearing seat 22, the distance between the raised toothed rings and the water chestnut falling space is adjusted to achieve opening processing for water chestnuts of different diameters.

The cutting roller 21 is also provided with a transmission gear 211 and a direction-changing gear 212 . The transmission gear 211 and the direction-changing gear 212 are arranged on the cutting roller 21 at intervals, and are linked with the shell breaking mechanism 3 through the transmission gear 211 and the direction-changing gear 212 .

The shell breaking mechanism 3 includes a second bearing seat 31, a knife shaft 32, a threaded knife cylinder 33, a socket cylinder 34 and a fixed knife plate 35; the second bearing seat 31 is arranged on the shell breaking bracket 52; the shell breaking bracket 52 is provided with an oblong hole matching the second bearing seat 31, and the position of the second bearing seat 31 is adjusted by installing the second bearing seat 31 at different positions of the oblong hole;

The two ends of the knife shaft 32 are provided with connecting bearings 23 matching the second bearing seat 31, and the connecting bearings 23 enable the knife shaft 32 to rotate relative to the second bearing seat 31;

The threaded cutter barrel 33 is sleeved on the cutter shaft 32. The rotation of the cutter shaft 32 drives the threaded cutter barrel 33 to rotate. A support column is provided between the cutter shaft 32 and the threaded cutter barrel 33. The threaded cutter barrel 33 is fixedly connected to the cutter shaft 32 through the support column. A threaded blade inclined at 30° is provided on the outer surface of the threaded cutter barrel 33.

The socket drum 34 is coaxially arranged with the threaded knife cylinder 33, and the socket drum 34 is sleeved on the outer side of the threaded knife cylinder 33. A gap is arranged between the socket drum 34 and the threaded knife cylinder 33 for the water chestnuts to pass through and break the shells; the socket drum 34 is evenly provided with penetrating drop-in holes 341, and connecting grooves 342 are arranged between the drop-in holes 341 on the concentric circles of the outer wall of the socket drum 34, and the connecting grooves 342 connect adjacent drop-in holes 341, and the depth of the connecting grooves 342 is not greater than the wall thickness of the socket drum 34.

When the water chestnuts enter the socket roller 34 and the threaded cutter cylinder 33 axis from the drop hole 341, the water chestnuts are squeezed and rolled between the inner wall of the socket roller 34 and the outer wall of the threaded cutter cylinder 33 by rotating;

The two sides of the socket drum 34 are respectively provided with a left end cover (not shown) and a right end cover (not shown), and the socket drum 34 is respectively mortised with the left end cover and the right end cover, and the left end cover and the right end cover are respectively provided with a connecting bearing 23, and the left end cover and the right end cover are rotatably connected to the knife shaft 32 through the connecting bearing 23;

The knife shaft 32 is provided with a driven gear 343 that matches the position of the transmission gear 211 of the cutting roller 21. The driven gear 343 is connected to the transmission gear 211 through a chain, and is driven by an external motor through the transmission gear 211 to achieve synchronous rotation of the knife shaft 32 and the cutting roller 21. The left end cover or the right end cover is provided with a reverse gear 344, and the reverse gear 344 matches the position of the direction-changing gear 212, and the reverse gear 344 meshes with the direction-changing gear 212.

When the external driving motor drives the knife shaft 32 and the cutting roller 21 to rotate forward, since the direction of rotation of the changing gear 212 and the reverse gear 344 are opposite, the reverse gear 344 drives the socket roller 34 to reverse. At this time, the water chestnuts that fall into the inner wall of the socket roller 34 and the outer wall of the threaded knife cylinder 33 are subjected to force to break the shell.

The fixed blade plate 35 is coaxially arranged with the socket drum 34, and the fixed blade plate 35 is arranged at the outer side of the socket drum 34. The fixed blade plate 35 is fixedly connected with the shell breaking bracket 52 by bolts. The top of the fixed blade plate 35 is opened to contact the bottom of the feed hopper 1. After the material is divided and opened, the water chestnuts enter the shell breaking mechanism 3 from the top of the fixed blade plate 35.

Double-edged rolling cutters 351 are arranged at intervals on the inner wall of the fixed blade plate 35. The arrangement position of the double-edged rolling cutters 351 matches the position arrangement of the connecting grooves 342 on the outer wall of the socket roller 34. The double-edged rolling cutters 351 are arranged obliquely at the inlet, so that the contact space between the double-edged rolling cutters 351 and the water chestnuts at the inlet is gradually reduced, and the water chestnuts are rolled and cut step by step.

A drop groove 352 is provided between the adjacent double-edged rolling cutters 351; the crushed water chestnuts fall into the receiving hopper 4 through the drop groove 352; in this scheme, the minimum distance between the socket roller 34 and the fixed knife plate 35 can be adjusted by adjusting the fixed position of the second bearing seat 31, and finally the water chestnuts of different particle sizes can be shelled.

Working principle: after the power is turned on and the external motor is started, the motor transmits power to the transmission gear 211 through the synchronous belt, driving the cutting roller 21 and the knife shaft 32 to rotate forward. At this time, the water chestnuts in the hopper are diverted by the material dividing guide 25 in the hopper under the action of gravity and fall down. The water chestnuts are cut while the cutting roller 21 is rotating. The cut sizes of water chestnuts with different diameters are different, and the cut depth can be freely adjusted according to the thickness of the water chestnut peel; the cut water chestnuts fall into the sockets on the socket roller 34 under the action of gravity. At this time, the socket roller The cylinder 34 is reversed due to the action of a pair of gears, and enters the fixed knife plate 35 driven by the socket roller 34. At this time, because the gap between the fixed knife plate 35 and the 30° threaded knife is smaller than the diameter of the water chestnut, the water chestnut rolls along the direction of the fixed knife due to the extrusion force and the socket roller 34. While rolling, the 30° threaded knife gives the water chestnut an axial force to break the outer shell of the water chestnut (the gap between the fixed knife plate 35 and the 30° threaded knife is adjustable); the broken water chestnut and kernel fall into the receiving hopper 4 and are discharged from the discharge port.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
