detailed description

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

The utility model provides a walnut sheller, as shown in Figure 1 and Figure 2, comprising a body 1, the outer top wall of the body 1 is fixed with a feed box 2, and the inside of the body 1 is fixed with an extrusion mechanism and a feeding plate 3 and the separation mechanism, the extrusion mechanism is located below the feed box 2, the feeding plate 3 is facing the bottom of the extrusion mechanism, the feeding plate 3 is inclined downward and extends to the top of the separation mechanism, and the side wall of the body 1 corresponds to the separation mechanism A discharge port 4 is provided.

The extrusion mechanism includes two extrusion rollers 5 arranged horizontally side by side. The two extrusion rollers 5 are connected between the opposite inner walls of the machine body 1 through bearings. The outer walls of the two extrusion rollers 5 are uniformly provided with a number of gaps along the circumferential direction. Groove 6, one end of one of the squeeze rollers 5 is also fixed with a pulley 7, the pulley 7 is connected with a first motor 8 through a transmission belt, and the ends of the two squeeze rollers 5 away from the pulley 7 are fixedly fitted with a gear 9, The two gears 9 mesh with each other, and the feeding plate 3 is located below the two squeezing rollers 5 .

The radii of the two squeeze rollers 5 are both 40mm, and the distance between the centers of the two squeeze rollers 5 is 105mm.

As shown in Figure 3 and Figure 4, the separation mechanism includes a separation barrel 10, the top of the separation barrel 10 is fixed with a material guide plate 11, the material guide plate 11 is an inverted conical shape with an opening at the bottom, and the upper part of the side wall of the separation barrel 10 is provided with a communication port 12 , the side wall of the separation barrel 10 is also fixed with a discharge box 13, the communication port 12 is connected with the discharge port 4 through the discharge box 13, the separation barrel 10 is provided with a rotary screen bucket 14, and the bottom of the rotary screen bucket 14 is axially A rotating shaft 15 is fixed, and the rotating shaft 15 passes through the bottom of the separation barrel 10 and is connected with a second motor 16. The rotating shaft 15 is connected to the output shaft of the second motor 16 through a coupling 17, and the top height of the rotary screen barrel 15 is not high. In the communication port 12.

The top opening of the rotary sieve bucket 15 is not smaller than the bottom opening of the guiding pan 11 .

The discharge box 13 is inclined downward along the direction from the communication port 2 to the discharge port 4 .

The shell breaking method of the double-roller walnut sheller is mainly completed by the relative reverse rotation of two equal-sized extrusion rollers 5. The gap between the two extrusion rollers 5 should be smaller than the average diameter of the walnut, which is essential for the walnut. Size statistics and calculate the average diameter d of the walnut is about 33mm, the amount of compression deformation δ is 8mm, and the relative extrusion angle of the twin rollers is θ is 22°, according to the formula Draw the radius R of extruding roller 5 to be 40mm; Then according to formula The center-to-center distance A of the two extrusion rollers is obtained to be 105mm. When the walnut passes through the gap groove 6 between the rough surfaces of the two extrusion rollers 5, the walnut shell is broken under the action of the friction and shear force of the extrusion roller 5; It utilizes the difference in physical properties between walnut shells and kernels, such as the difference in particle size and density between the shells and kernels, and realizes the relative movement between the shells and kernels through the low-speed rotation of the rotary sieve barrel 14, so as to achieve the layering and harmony between the shells and kernels. Through the sieve. Leading tray 11 is designed to be inverted conical and fixed on the upper shell of separation bucket 10, and the opening of rotary sieve barrel 15 is greater than the bottom opening of feeding tray 11, which can prevent shell kernels from flying out during the separation process of shell kernels. The rotary screening type shell and kernel separation method is low in cost, easy to operate, and has no toxic and side effects on walnuts, which is beneficial to the batch processing of walnuts.

During use, walnuts are dropped into the feed box 2, and then the walnuts fall into the gap formed by the two extrusion rollers 5, and the first motor 8 drives the pulley 7 through the transmission belt and then drives one of the extrusion rollers 5 to rotate automatically, and then passes The gear 9 fitted on the other end of the two squeeze rollers is meshed and driven, so the two squeeze rollers 5 move towards each other, and the rotation direction of the pulley is adjusted so that the two squeeze rollers 5 rotate from top to bottom in the middle of the two squeeze rollers.
