Background technique

Dried fruit is a major oil crop. Dried fruit has high nutritional value and can also be made into many people's favorite foods. However, dried fruit such as peanuts, walnuts, almonds, etc. must go through a shelling process before deep processing or making food. Traditional manual shelling Shelling is labor-intensive and inefficient. Most of the existing shelling machines adopt a drum-type or flat-grinding-type structure, which has low production efficiency and unreasonable shelling structure, which leads to unsatisfactory shelling results and even serious damage to dried nuts. The phenomenon. Therefore need to invent a kind of shelling efficiency height, shelling quality is stable, the shelling device of dried nut damage rate is low.

The purpose of the present invention is achieved through the following technical solutions:

A device for shelling dried fruits with conical grinding discs, comprising a rotating grinding disc and a fixed grinding disc, the fixed grinding disc is fixed on a frame, and the rotating grinding disc is mounted on the fixed grinding disc through a vertical transmission shaft, so that the rotating grinding disc passes through The transmission shaft drives to rotate relative to the fixed grinding disc. A gap larger than the outer diameter of the dried fruit is provided between the rotating grinding disc and the fixed grinding disc to form a shelling space. The middle part of the rotating grinding disc is provided with a feed port and the shelling The shell space is connected, and the opposite surface of the rotating grinding table and the fixed grinding table is a downwardly inclined conical surface so that a downward passage is formed around the shelling space, and the rotating grinding table and the fixed grinding table are on the opposite surface. The radial extension of the fixed grinding disc covers the sliding channel of the entire shelling space, and the gap between the ribs on the rotating grinding disc and the opposite surface of the fixed grinding disc is smaller than the outer diameter of the dried fruit and larger than the outer diameter of the dried nut kernel.

A shaft end fixing device, a fixed grinding disc, an adjusting washer, a rotating grinding disc and a rotating grinding disc adaptive device are sequentially installed on the transmission shaft from bottom to top, and the rotating grinding disc adaptive device includes a washer, a spring and The positioning nut, the washer is arranged under the positioning nut, the spring is arranged between the rotating grinding disc and the washer, and the spring pressure is adjusted by locking the position of the positioning nut on the transmission shaft.

The ribs on the rotating grinding table and the fixed grinding table are curved, and the bending direction of the rib curve is the same as the rotating direction of the rotating grinding table.

The raised heights of the ribs on the rotating grinding disc and the fixed grinding disc are the same.

The rotating grinding disc and the fixed grinding disc are respectively provided with eight ribs.

Due to the adoption of the above technical scheme, the dried fruit is fed from the feeding port and falls into the shelling space, and then the dried fruit slides down along the conical surface of the fixed grinding table under the action of gravity, and produces relative motion through the protruding ribs arranged on the rotating grinding table and the fixed grinding table , to produce shearing and squeezing action on the dried fruit sliding down the inclined surface of the grinding disc to complete the shelling of the dried fruit. Since the gap between the rotating millstone and the fixed millstone is greater than the outer diameter of the dried fruit, and the gap between the ribs on the rotating millstone and the opposite surface of the fixed millstone is smaller than the outer diameter of the dried fruit and greater than the outer diameter of the dried kernel, the dried fruit can be guaranteed The smooth sliding also ensures the shearing and squeezing of the dried fruit, achieving the effect of breaking the shell of the dried fruit and separating the shell and kernel without breaking the dried kernel. Since the curved direction of the curves of the rotating grinding disc and the ribs on the fixed grinding disc is the same as the rotating direction of the rotating grinding disc, the ribs produce extrapolation when the rotating grinding disc rotates to ensure smooth discharge. Due to the adoption of the self-adaptive device of the rotating grinding disc, the device can also automatically adapt to the shelling process of batches of dried fruits with different particle sizes and different degrees of hardness.

To sum up, the device has high shelling efficiency, good shelling quality, low damage rate of dried nuts and stable output.

detailed description

A specific embodiment of a cone-type grinding disc dried fruit shelling device will be described below in conjunction with the accompanying drawings.

As shown in Figures 1 to 3, a dried fruit shelling device with a conical grinding disc includes: a rotating grinding disc 1, a fixed grinding disc 2, a transmission shaft 3, a positioning nut 4, a spring 5, a washer 6, a flat key 7, a washer 8, Adjust the washer 9, the upper tapered roller bearing 10, the lower tapered roller bearing 11, the fastening nut 12, and the upper rib 13 fixed on the rotating grinding disc 1 and the lower rib 14 fixed on the fixed grinding disc 2. The transmission shaft 3 is designed with two threads and two keyways; the transmission shaft 3 is sequentially installed with two fastening nuts 12, washers 8, and a fixed grinding disc 2, and an upper tapered roller is installed in the bearing hole of the fixed grinding disc 2. Sub-bearing 10 and lower tapered roller bearing 11, adjusting washer 9, rotating grinding disc 1 and rotating grinding disc adaptive device, said rotating grinding disc adaptive device includes washer 6, spring 5 and two positioning nuts 4, and said spring 5 sets Between the rotating grinding disc 1 and the washer 6, the positioning nut 4 is a pair of nuts, and the spring pressure is adjusted by locking the position of the positioning nut on the transmission shaft, so as to achieve the shelling process of dried fruit suitable for batches of different sizes and hardness the goal of. After the fastening nut 12 is locked, the axial positioning of the fixed grinding disc 2 is realized, and the tapered roller bearing is adopted to bear axial and radial forces.

The transmission shaft 3 rotates in the forward direction and drives the rotating grinding disc 1 to rotate forward through the flat key 7. The fixed grinding disc 2 is installed on the frame through four bolt holes 15 and remains still. The opposing surfaces of the rotating grinding disc 1 and the fixed grinding disc 2 are designed to Outwardly inclined conical surface, while the gap between the rotating millstone 1 and the opposite surface of the fixed millstone 2 is greater than the outer diameter of the dried fruit, the gap between the top surface of the upper rib 13 and the cone surface of the fixed millstone 2 is smaller than the outer diameter of the dried fruit and It is larger than the outer diameter of the dried nuts, so as to ensure that the dried fruits are sheared and squeezed without damaging the dried nuts. The transmission shaft must rotate in the forward direction. At the same time, in order to facilitate the discharge, the bending direction of the rib is designed to be consistent with the direction of rotation. In this way, when rotating in the forward direction, the rib can produce an external push effect, thus ensuring the smooth outward sliding of the dried fruit.
