Description

Equipment for breaking walnut shells

technical field

The present invention relates to a device for shelling walnuts.

Background technique

Walnut shells are wrinkled and hard, and it is difficult to break walnut shells manually. To improve the efficiency of shell breaking, mechanical breaking of walnut shells is the best solution. However, in the prior art, shell breaking machines generally adopt three methods of impact breaking, shear breaking, and extrusion breaking. Disclosed name as Chinese Patent No. 102652576A is called "centrifugal walnut shell breaking machine" and adopts a kind of equipment of impacting broken shells. This kind of shell breaker is equipped with a moving knife set under the material inlet of the shell, and the moving knife set is fixed on the transmission shaft vertically placed below it through a locking sleeve. The transmission shaft is connected with the upper wall of the body through a bearing, and the A support plate is provided on the outside of the body, and a material guide plate with an outlet is provided above the tilting and rotating body. In the process of cracking walnut shells in this kind of shell breaking machine, the walnuts enter the shell breaking area from the feed port and are thrown out by the high-speed rotating moving knife group, so that they hit the guide plate to achieve shell breaking. Although this kind of shell breaking machine can break walnut shells, due to the different hardness of walnut shells, in the process of breaking walnut shells, walnut shells with high hardness are not easy to be damaged, and walnut shells with low hardness are easy to damage walnut kernels, so Also propose secondary cracking shell and walnut kernel grinding damage etc. in this cracking machine.

Chinese patent No. 102669797A discloses the name "volute walnut shell breaking machine with pumping drum" which also adopts the mode of impact breaking shell. The turntable and pumping drum are synchronously linked. When the feeding trough on the feeding turntable passes under the feeding hopper, a single walnut falls into the feeding trough through the inlet of the feeding turntable and rotates together with the feeding turntable. When the trough passes through When the feeding turntable exits, the walnuts are freely dropped to the pumping chamber below through the connecting channel in the connecting pipe to complete the feeding; at the same time, the pumping drum drives the pumping blades to rotate to the bottom of the connecting pipe at a certain speed during the falling process of the material. With the help of the pumping protrusions on the surface of the whipping blade, the walnut is smashed for the first time with a certain impact force; after the first pumping and shelling, the walnut flies into the collision chamber by virtue of its inertia, and then collides with the second impacting tooth. Then, under the action of the inclination angle of the second impact tooth plate, most of the walnut nuts and broken shells are discharged through the discharge port below the collision chamber after the second impact, and a very small amount It will enter the pumping chamber and be discharged from the discharge port below the pumping chamber to complete a shell breaking cycle. It can be seen that this kind of cracking machine also has problems such as secondary cracking and grinding damage to walnut kernels, which cannot be achieved once cracking shells and not damaging walnut kernels.

In addition, since there are two types of walnut shells, thin shells and thick shells, and the hardness of the same type of thin shells and thick shells is not exactly the same, it is easy to damage walnut kernels if shearing equipment is used. Cutting the shell can't achieve the desired effect.

The most ideal effect of extruding walnut shell breaking equipment is to solve the problem of secondary shell breaking. For example, the name of the Chinese patent No. 203087473U announcement is "gear type walnut sheller", which is a kind of extrusion walnut shell breaking machine. equipment. This kind of peeling machine is composed of a transmission mechanism, a shell breaking mechanism, a center distance fine-tuning mechanism and a motor. The transmission mechanism is composed of a motor, a pulley, and a belt; , external gear drive roller, gear teeth and discharge parts; the center distance fine-tuning mechanism is composed of adjusting bolts, limit slots, and rotary shaft positioning devices. In the process of cracking walnut shells, walnuts are input from the feeding hopper into the inner tooth fixed cylinder, and driven by the transmission mechanism, the walnut shells are squeezed and broken by two gear teeth. Although this device can break the walnut shell at one time, for larger walnuts, the walnut kernel is easily damaged in the process of breaking the walnut shell. Contents of the invention
