Description

Multifunctional Nut Sheller

technical field

The invention belongs to the field of machinery, and in particular relates to a multifunctional nut shell breaking machine.

Background technique

At present, cracking of almond shells and apricot cores is entirely dependent on simple nut shelling machines. The operation is inefficient, labor-intensive, prone to fatigue, time-consuming, and has a single function. The low-efficiency cracking of almonds and apricot cores has plagued the development of the almond industry. Therefore, there is an urgent need for a high-efficiency mechanized processing equipment in the almond and apricot industries.

The present invention is improved on the basis of utility model patents (ZL200720183102.7, ZL201020218891.5 and ZL201620720926.2). Patents ZL200720183102.7 and ZL201020218891.5 have the problem of continuous cracking of shells. Patent ZL200720183102.7 has the problem that the shell-breaking roller is a smooth roller, and the effect of breaking the almond kernels is better. Because the apricot kernels are relatively brittle and easy to break the shells, but the almond kernels are flexible, the shell-breaking effect of this shell-breaking mechanism is not ideal, the shell breaking rate is low, the vibrating screen is noisy and easy to break, and the broken almonds cannot completely fall from the sieve holes into the lower sieve.

Contents of the invention

The object of the present invention is to provide a multifunctional nut shell breaking machine, which not only has good shell breaking effect, but also has high working efficiency.

The object of the present invention is achieved in the following way: a multifunctional nut shell breaking machine, comprising a frame, the front and rear parts of the frame are respectively provided with a scraper conveyor and a lifting screw, the front of the frame is provided with a vibrating feeder, and a circulating feeding trough is arranged obliquely above the frame, the inlet end of the circulating feeding trough is connected with the top of the lifting screw, the outlet end of the circulating feeding trough is located above the vibrating feeder, and the front, middle and rear three sets of shell breaking mechanisms are arranged on the frame from the front to the rear in order to form a high and low level; The shell mechanism is composed of a horizontal conveyor belt, a horizontal shell breaking roller, a roller shaft height adjustment mechanism installed at both ends of the shell breaking roller, and a trommel. The trommel is driven by a motor to rotate. The front and rear parts of each trommel are respectively equipped with a feed inlet and a discharge outlet. In the material trough, scrapers are arranged on the central axis of the rotating shaft of each trommel, and the scrapers are arranged along the axial direction of the trommel, and the above-mentioned shell breaking rollers are arranged horizontally and laterally above the idler rollers at the end of each horizontal conveyor belt.

The roller shaft height adjustment mechanism includes bearing housings arranged at both ends of the roller shaft. The two sides of the frame are respectively fixed vertically to the slideway with the lead screw inside. A hand wheel is arranged at the top of one side of the screw, and the top of the bearing housing is connected to the lower end of the screw respectively.

When the present invention works, the almond or apricot core is transported to the vibrating feeder through the scraper conveyor, and the vibrating feeder evenly feeds the almond or apricot core into the feeding port through vibration, and the almond or apricot core falls evenly onto the horizontal conveyor belt through the feeding port. Apricot kernels, shelled almonds or apricot kernels enter the drum through the feed port of the drum, and the broken cores are discharged from the discharge port through the screen holes on the drum. The almonds and almonds are discharged through the diamond-shaped screen holes. The sieve holes on the drum are discharged from the discharge port, and the almonds or apricot kernels of the first grade enter the third-stage conveyor belt through the discharge port, and are transported to the third-stage shell breaking mechanism. Uncracked almond or apricot kernels are transported to the discharge port, and then transported to the vibrating feeder through the discharge port, and then continue to crack the shell, and the cycle is repeated to achieve the purpose of complete shell cracking.

The technical solution of the present invention: 1. The shell breaking of almond kernels with different sizes can be completed at one time, and the shell breaking rate is high; the material transported by the food conveyor belt in the middle of the shell breaking mechanism plays a profiling role, reducing the broken rate of kernels. 2. A trommel screen is added to the first-stage shell breaking device, the second-stage shell breaking device and the third-stage shell breaking device, which avoids the secondary crushing of the almond kernels and improves the integrity rate of the kernels; 3. The shell breaking machine is equipped with a vertical elevator to transport the unbroken almonds to the vibrating feeder for continuous shell breaking, which improves the shell breaking rate and reduces the labor intensity. 4. The roller grading machine solves the problem of unsatisfactory grading of nuts with grids for commonly used rollers through the combination of screens. It has a simple structure, is easy to manufacture, has low noise, and works reliably. 5. Not only the cracking speed is fast, but also the work efficiency is high. It also solves the problems of inconvenient adjustment of the cracking gap of the nut shelling machine and uneven gap between the cracking rollers. 6. The shell cracking machine is designed with a synchronous adjustment mechanism to adjust the cracking gap according to the thickness of the nuts. It solves the inconvenient and uneven problem of adjusting the cracking gap of the simple cracking machine, and also designs a tension wheel adjustment mechanism with a simple structure, which is more convenient to adjust.
