Detailed Description

The present invention will be further explained with reference to the drawings and the embodiments.

First embodiment

The first embodiment is the basic solution of all embodiments of the present invention, and in this embodiment, the problem to be solved is how to propose a new walnut shell crushing solution, which can realize the continuous crushing of walnut shells.

Referring to fig. 3-8, the core of the walnut shell crushing device provided by this embodiment lies in how to periodically complete the processes of feeding, extruding and discharging. Therefore, the rotating disc type rotating device is adopted in the embodiment, the rotating extrusion device periodically rotates relative to the blocking device, and the processes of feeding, extruding and discharging are achieved one by one through the periodic change of the positions of the rotating extrusion device and the blocking device.

Therefore, the rotary extrusion device and the blocking device of the embodiment are connected through the rotating shaft to form a rotating pair. The rotary extrusion device and the blocking device periodically form a extrusion chamber when the rotary extrusion device rotates relative to the blocking device. The extrusion cabin is provided with a feeding port, a discharging port and an extrusion component. The squeezing component in the embodiment is a squeezing block and a blocking block which are arranged in the squeezing cabin, and the space in the squeezing cabin is compressed through the opposite movement of the squeezing block and the blocking block, so that the walnut shell is stressed and crushed under the squeezing action.

Referring to fig. 2 to 8, in the present embodiment, the rotary extrusion device is composed of an upper extrusion plate (7), a middle extrusion plate (4), and a lower extrusion plate (9); and the blocking device is a rack upper panel (6). As shown in the figure, the middle extrusion disk (4) is provided with an annular side plate with certain width and thickness; on the other hand, a circular rotary extrusion device mounting cavity is formed in the upper panel (6) of the rack, and an arc-shaped groove is formed in the edge of the circular mounting cavity, so that the mounting cavity is in a plum blossom shape. The edge of the plum blossom-shaped cavity is also provided with a side plate corresponding to the middle extrusion plate. On the basis, a rotary extrusion device consisting of an upper extrusion disc (7), a middle extrusion disc (4) and a lower extrusion disc (9) is combined with the upper panel (6) of the frame, so that the rotary extrusion device can freely rotate in a circular cavity of the upper panel (6) of the frame, and the inner wall of the extrusion chamber is formed at the arc-shaped groove by the upper extrusion disc (7), the middle extrusion disc (4), the lower extrusion disc (9) and the upper panel (6) of the frame.

For the extrusion chamber, as the rotating extrusion device rotates relative to the blocking device continuously, the extrusion chamber also completes the process of extrusion chamber formation-disappearance continuously and periodically. The extrusion blocks of the embodiment are arranged on the lower surface of the upper extrusion disc (5) and the outer side surface of the middle extrusion disc (4) and also rotate periodically with the rotation of the rotary extrusion device. The corresponding stop block is an end face of the arc-shaped groove of the upper panel (6) of the rack in the embodiment, when the extrusion block pushes the walnut to be crushed to move to the end part of the arc-shaped groove, the end face of the upper panel (6) of the rack is compressed relative to the extrusion block, and inward extrusion force is provided for crushing the walnut.

To the pan feeding of material in the extrusion cabin, ejection of compact problem, the scheme that this embodiment adopted is with the pan feeding mouth setting at the extrusion cabin front end, and with the discharge gate setting at extrusion cabin rear end. In the extrusion process, the walnut to be crushed firstly enters the extrusion chamber from the feeding port at the head part, then the shell is damaged under the action of the extrusion block and the stop block, and finally the walnut is discharged from the discharge port at the tail part of the extrusion chamber, so that the purpose of the embodiment is realized.

Furthermore, one of the solutions provided in this embodiment is to automatically complete the feeding and discharging steps by using gravity. For this reason, the scheme adopted by this embodiment is: the feeding port is arranged at the upper part of the upper extrusion disc (5), the discharging port is arranged at the lower part of the lower extrusion disc (9), the feeding section of the feeding port is not overlapped with the discharging section of the discharging port, and the extrusion block is arranged between the feeding port and the discharging port. In this technical scheme, the material can fall into the extrusion under-deck automatically based on gravity to accomplish behind the extrusion action in the under-deck, fall out from the discharge gate automatically based on gravity.

Furthermore, the extrusion block in the embodiment adopts a gradual-change extrusion mode, the blocking degree of the extrusion block is gradually increased, and the walnut shell is gradually clamped through a smoother transition mode.

It should be understood by those skilled in the art that the above description is only one of the preferred embodiments of the present invention, and the above components are simply replaced, for example, the position of the extrusion block on the upper, middle and lower extrusion plates (5, 4, 9) is adjusted, or the component parts of the rotary extrusion device and the blocking device are exchanged, and the same operation principle is adopted, and the protection scope of the present invention falls into, and the present invention is not repeated.

Second embodiment

This example, as a variation of the first example, is aimed at improving the walnut shell breaking efficiency and realizing the continuous breaking of a plurality of walnut shells.

In the first embodiment, the number and the position of the ballast are not limited. Because the extrusion cabin of single walnut does not need the arc wall space of overlength, can set up a plurality of extrusion cabins according to the rotation axis array ground of rotatory extrusion device. Thereby realizing the industrial continuous production and improving the production efficiency.

For the arrangement of the extrusion chambers, it is preferable to arrange an even number of extrusion chambers on a circumference, and to distribute each pair of extrusion chambers axially symmetrically about the axis of rotation. The benefit that the axisymmetric formula distributes lies in the order the utility model discloses an extrusion device provides the atress by the extrusion cabin of a pair of symmetry simultaneously when extrudeing the breakage, and the eccentric force that produces when avoiding single extrusion cabin atress alone destroys the rotation axis.

However, in the above solution, the multiple pairs of symmetrically distributed ballast chambers result in an increase in the energy required at the moment of crushing, and the requirements on the drive means are high. Therefore, one of the available schemes is to adjust the extrusion positions or the forming time of the extrusion chambers of different groups (each pair of extrusion chambers is a group), so that the extrusion chambers of different groups complete the extrusion action in sequence, only one pair of walnuts are extruded during each extrusion, and the power requirement on the driving device is reduced.
