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

With the adjustment of Xinjiang's agricultural industrial structure, almonds and apricots have become the characteristic economic crops of Xinjiang's rural economic development. At present, almond shelling and apricot core shelling are completely dependent on simple nut shelling machines, and the operating efficiency is low. High labor intensity, easy fatigue, long time-consuming, single function, low-efficiency almond and apricot kernel cracking operations have plagued the development of the almond industry, so there is an urgent need for a high-efficiency mechanized processing in the almond and apricot industry operations equipment.

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 shell breaking, and the kernels after breaking the shell are easy to be used twice The damage leads to a high rate of broken kernels. The patent ZL200720183102.7 has the problem that the shell breaking roller is a smooth roll, and the effect of breaking the apricot core is better. Because the apricot core is relatively brittle, it is easy to break the shell, while the almond core is 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 it is easy to break, and the almond wood kernels after the shell breaking can not fall into the lower sieve from the sieve hole completely.

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 like this: a kind of multi-functional nut breaking machine, comprises frame, and the front and rear part of frame is provided with scraper conveyor and lifting screw respectively, and the front part of frame is provided with vibrating feeder, A circulating feeding trough is arranged obliquely above the frame, the inlet end of the circulating feeding trough is connected to the top of the lifting screw, the outlet end of the circulating feeding trough is located above the vibrating feeder, and the frame is connected from front to back in order to form a high and low The front, middle and rear three groups of shell breaking mechanisms are arranged horizontally; each set of shell breaking mechanisms consists of a horizontal conveyor belt, a horizontally placed shell breaking roller, roller shaft height adjustment mechanisms at both ends of the shell breaking roller, and a trommel screen. The trommel screen is driven by a motor to rotate. The front and rear parts of each trommel screen are respectively equipped with a feed inlet and a discharge port. The back half of the cylinder wall of the trommel screen at the feed port is densely covered with diamond-shaped screen holes, and the corresponding discharge troughs are respectively set under the square screen holes and the diamond-shaped screen holes. A scraper is installed on the central axis of the rotating shaft of each drum screen. The plates are arranged along the axial direction of the trommel screen, and above the idler roller at the discharge end of each horizontal conveyor belt, the shell breaking rollers are arranged horizontally and transversely.

The roller shaft height adjustment mechanism includes bearing seats respectively arranged at both ends of the roller shaft, and the two sides of the frame are respectively fixed vertically to the slideway with the lead screw inside, wherein a handwheel is arranged at the top of one side of the lead screw, and the top of the bearing seat They are respectively connected to the lower end of the lead screw, and the bearing seat slides up and down along the slideway. The upper parts of the lead screw in the slideways on both sides are respectively equipped with sprockets horizontally. The sprockets are driven by chains. When the handwheel is turned, the sprockets on both sides rotate synchronously. , so as to drive the screw to drive the bearing seat and the roller shaft to adjust the height synchronously.

When the present invention worked, the almond or apricot stones were transported to the vibrating feeder by a scraper conveyor, and the vibrating feeder evenly fed the almonds or apricot stones into the feeding port through vibration, and the almonds or apricot stones The kernels fall evenly onto the horizontal conveyor belt through the feeding port. When the almonds or apricot kernels on the conveyor belt pass through the shell breaking mechanism, the shell breaking rollers, supporting rollers and conveyor belt will squeeze the almonds or apricot kernels. Kneading (the synchronous adjustment mechanism evenly adjusts the gap according to the thickness of the nuts) first breaks the large almond or apricot core, after the shell is broken, the almond or apricot core enters the drum through the feeding port of the drum, and the core debris passes through the sieve holes on the drum The almonds and almonds are discharged from the outlet, and the almonds and almonds are discharged through the diamond-shaped sieve holes. The almonds or almonds that have not been shelled (intermediate almonds or apricot kernels) are transported to the conveyor belt through the roller outlet, and passed through the conveyor belt. After entering the secondary shell-breaking mechanism, the almond or apricot kernel after shelling enters the middle drum screen through the drum feed port, and the core debris is discharged from the discharge port through the sieve holes on the drum. The wood or apricot core enters the third-stage conveyor belt through the discharge port, and is transported to the third-stage shell breaking mechanism. After the shell is broken, the almond wood or apricot core enters the drum screen through the drum feed port, and the core debris The almonds and almonds are discharged from the outlet through the sieve holes on the drum, and the almonds and almonds are discharged through the diamond-shaped sieve holes. The unbroken almonds or apricot kernels fall into the feed port of the vertical elevator, and the vertical elevator conveys the blades through the screw. The almonds or apricot kernels that have not been cracked 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 completely cracking the shell.

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. The drum 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 of the kernels; 3. The shell breaking machine A vertical hoist is added to transport the uncracked almonds to the vibrating feeder again for continuous cracking, which increases the cracking 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 shell breaking speed is fast, but also the work efficiency is high. It also solves the problems of inconvenient adjustment of the shell breaking gap of the nut shelling machine and uneven gap between the shell breaking 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.
