Detailed Description

The oil tea fruit is broken by using the characteristics of natural cracks of the shells and weak shearing resistance, and the shells can be broken under a small extrusion acting force by adopting a rubbing method, so that the damage of internal tea seeds is reduced, and the processing quality is improved. Referring to fig. 1 and 2, the rubbing type camellia oleifera fruit hull breaking machine comprises a frame 1, and a feed hopper 2, a conveying belt unit, a rubbing unit and a discharge port 14 which are arranged on the frame 1. The conveying belt unit comprises a driving roller 3, a conveying belt 4, a carrier roller frame 5, an adjusting spring 6, a plurality of carrier rollers 7 and a driven roller 13; the kneading unit comprises a top plate 8, a kneading motor 9, a driving crank 10, a kneading plate 11 and a driven crank 12.

As shown in fig. 1, the driving roller 3, the idler roller 7 and the driven roller 13 of the conveyor belt unit are provided with rectangular grooves. The conveyor belt 4 is made of a textile material and has flexibility, the front surface is provided with textures, and the bottom surface is provided with rectangular guide strips. The guide strips of the conveyor belt 4 are embedded in the rectangular grooves of the rollers. A plurality of carrier rollers 7 are arranged on the bottom surface of the belt right below the kneading plate 11, and the carrier rollers 7 are arranged on the carrier roller frame 3. The roller frame 5 is fixed on the frame 1 through an adjusting spring 6 and is used for adjusting the extrusion force applied on the oil tea fruits. In the real-time fruit of kneading, the horizontal effort that the conveyer belt bore transmits each roller through the gib block, prevents that the conveyer belt from horizontal migration on the roller, the phenomenon of "off tracking" appears.

As shown in fig. 1 and 2, the top plate 8 of the kneading unit is fixed to a support column on the frame 1. The kneading motor 9 fixed on the top plate 8 is connected with the optical axis of the driving crank 10. The kneading plate 11 has three fixed vertical optical axes, which are uniformly arranged on an equilateral triangle, and the top plate 7 also has shaft sleeves with completely identical positions. The length dimensions of the driving crank 11 and the two driven cranks 12 are equal. One end of the three cranks is an optical axis, and the other end is provided with a shaft sleeve. The optical axis ends of the three cranks are connected with the shaft sleeves of the top plate 8, and the shaft sleeve ends are connected with the optical axis on the kneading plate 11, so that a space link mechanism is formed. When the kneading motor 9 rotates, the driving crank 10 drives the driven crank 12 to rotate together, so as to ensure that the kneading plate 11 always moves longitudinally and transversely on a plane parallel to the conveyor belt 4 as shown in fig. 3, and the motion trail of any point on the kneading plate is a circle.

During operation, the sorted oil tea fruits with the diameter within a certain range uniformly enter the hopper 2, automatically fall onto the conveyor belt 4, and move together with the conveyor belt 4 to enter the lower part of the kneading plate 11. When the kneading plate 11 is driven by the

cranks

10 and 12 to do kneading movement, the acting force born by the shell comprises: 1) the pressing force between the kneading plate 11 and the conveyor belt 4; 2) friction at the contact of the conveyor belt 4; 3) friction at the contact of the kneading plate 11. The three forces generate squeezing effect and shearing effect on the shells, so that the shells are broken, the shells are separated from the tea seeds in the shells, the broken shells and the tea seeds continuously move together along with the conveyor belt 4 and are discharged from the discharge port 14, and the shell breaking process is completed. In the kneading process, a small amount of firm husks are not broken, at the moment, the husks enable the compression force applied to the adjusting spring 6 to exceed the preset spring compression force, the gap between the conveyor belt 4 and the kneading plate 11 is increased, fruits penetrate through the kneading plate 11 and are discharged from the discharge hole 14 along with the conveyor belt 4, and the condition that the fruits which are not broken are not accumulated at the inlet of the kneading plate 11 is ensured.
