The Chinese chestnut falls into the roller box inlet, and the roller and the driven roller are both orderly provided with roller teeth and reversely rotate at different speeds, and the Chinese chestnut is torn by utilizing the difference of the rotating speeds of the rollers and is extruded to realize the hair removing and thorn processing of the Chinese chestnut. The space between the roller teeth between two running rollers is as the buffer, can avoid the chinese chestnut too much and to the influence that work caused, drops from the gap between the cutter through the chinese chestnut that the roller teeth was shelled and gets into screw conveyor, takes off the fluffy portion of first order and consolidate and fill up, and in transportation process, the chinese chestnut is through the pitch of equidimension not, accomplishes thoroughly taking off fluffy of chinese chestnut. The chestnut and chestnut bur shells which are thoroughly removed from the burs fall into a vibrating screen from an outlet of a spiral box body. The output end of the bevel gear speed reducing motor is connected with the V-belt wheel 2-E, the connecting rod A is hinged with the V-belt wheel 2-E and the screen to form a crank block structure, and the bevel gear speed reducing motor operates to drive the V-belt wheel 2-E to rotate so as to drive the screen to vibrate. The vibrating screen consists of two layers of screen plates. The first layer of vibrating screen roughly separates burrs from chestnuts, leaves the shells of the burrs of the chestnuts above the sieve plate, and falls into the burr shell collection basket from the sieve plate through vibration. The Chinese chestnuts and some small squeezed burrs fall from the sieve plate holes and enter the second layer of sieve plate for sieving, the second layer of vibrating sieve separates the Chinese chestnuts from the small crushed burrs, the small crushed burrs fall into the burr shell collecting basket, and the Chinese chestnuts are left on the vibrating sieve and fall into the conveying mechanism.

The chestnuts to be shelled enter a conveying mechanism. The motor C works, the V belt wheel 3-A, V belt wheel 3-B, V belt wheel 3-C, V belt wheel 3-D, V belt wheel 3-E is driven to rotate through the V belt, the shaft 3-A is connected with the V belt wheel 3-B, the shaft 3-B is connected with the V belt wheel 3-C, the shaft 3-C is connected with the V belt wheel 3-D, the shaft 3-D is connected with the V belt wheel 3-E, the transmission belt B is sleeved on the shaft 3-A and the shaft 3-B, and the transmission belt C is sleeved on the shaft 3-C and the shaft 3-D, so that the transmission belt B and the transmission belt C run. The chestnuts are conveyed to the outlet of the conveying mechanism from low to high through a conveying belt B and a conveying belt C.

The Chinese chestnut to be shelled enters a Chinese chestnut shelling mechanism. The Chinese chestnut falls into the shunting input structure, is divided into 15 rows by the baffle and enters the Chinese chestnut plate, so that the Chinese chestnut can fall into the Chinese chestnut plate groove better. The V-belt wheel 4-B fixed at one end of the shaking shaft is connected with the V-belt wheel 4-A through a V belt, the Chinese chestnut plate is hinged with a shaking connecting rod A, the shaking connecting rod A is hinged with a shaking connecting rod B, and the shaking connecting rod B is hinged with a shaking crank fixed at the other end of the shaking shaft. And the motor D works to drive the lower pressing shaft, the vibrating screen crank wheel connected with the lower pressing shaft, the vibrating screen driven crank driving wheel and the V-shaped belt wheel 4-A to rotate back and forth, so that the Chinese chestnut plate is driven to vibrate, and the Chinese chestnuts are shaken into the grooves. The vibrating screen driven wheel A, the vibrating screen driven wheel B, the vibrating screen crank wheel and the vibrating screen driven crank driving wheel rotate towards the direction of the grinding structure to drive the pressing plate to press downwards, and the cross knife in the groove of the pressing plate opens the chestnut. The driven wheel A of the vibrating screen, the driven wheel B of the vibrating screen, the crank wheel of the vibrating screen and the driven crank driving wheel of the vibrating screen rotate in the opposite direction to drive the pressing plate to lift. The motor E operates to drive the ejection shaft connected with the output shaft of the motor E to rotate through the coupler, so that the ejection disc rotates and moves up and down, and chestnuts are ejected from the grooves. The motor F operates to drive the chain transmission shaft A to reciprocate, two ends of the chain transmission shaft A are respectively connected with the chain wheel 4-A and the chain wheel 4-C, two ends of the chain transmission shaft B are respectively connected with the chain wheel 4-B and the chain wheel 4-D, so that the chain A and the chain B move simultaneously, the chain transmission shaft A is fixedly connected with the chain A and the chain B and moves along with the chain, and chestnuts are pulled out. The chestnut plate outlet is provided with an outlet A and an outlet B, wherein the outlet A is connected with the millstone funnel, and the two outlets are opened and closed by manually turning the small door. When the Chinese chestnut just falls into the Chinese chestnut plate, the outlet A is closed, the Chinese chestnut which does not enter the groove is pulled out of the Chinese chestnut plate through the outlet B by the pulling structure, the Chinese chestnut plate is manually collected and poured into the Chinese chestnut plate inlet again, and the steps are repeated until all the Chinese chestnuts are opened.

The motor G operates to drive the small V-shaped belt wheel to rotate, and then the grinding shaft connected with the large V-shaped belt wheel is driven to rotate through the V-shaped belt, so that the movable grinding disc is driven to rotate. After entering the device from the hopper, the Chinese chestnuts fall on the movable grinding disc under the action of gravity, change the motion direction under the action of the movable grinding disc to collide with the fixed grinding disc, and then move towards the edge under the action of gravity and centrifugal force, and act with the bulges of the movable grinding disc and the fixed grinding disc in the process to finish shelling.
