A support 6 is connected to the outer wall of the cylinder 1 near its bottom; it also includes a crushing and filtering assembly 7 and a cleaning assembly 8. The crushing and filtering assembly 7 is arranged at the bottom ends of the cylinder 1 and the screw member 2 and is used for crushing and filtering the dry tung seeds during pressing. The cleaning assembly 8 is arranged between the cylinder 1 and the feed hopper 3 and is used for cleaning the inside of the cylinder 1. A horizontally arranged mounting bracket 4 is installed inside the feed hopper 3. A reduction motor 5 is arranged at the top of the mounting bracket 4. The output shaft of the reduction motor 5 is fixedly connected to the top center position of the screw member 2 through a coupling.

[0021] Furthermore, the crushing and filtering assembly 7 includes a discharge cylinder 71, a secondary filter screen 72 and a primary filter screen 73. The discharge cylinder 71 is detachably installed at the bottom port of the cylinder 1.

The primary filter screen 73 for intercepting dry tung seeds is inlaid at the bottom port of the cylinder 1. The crushing and filtering assembly 7 also includes extension rods 74 and crushing teeth 75. Through the cooperative design of the cylinder 1, the screw member 2 and the crushing and filtering assembly 7, the dry tung seeds can be crushed during the pressing process, reducing the gaps in the dry tung seeds during pressing, thereby improving the oil yield of the equipment. At the same time, the tung oil obtained by pressing can be double-filtered to intercept the residues and impurities in the dry tung seeds, improving the quality of the tung oil. A plurality of horizontally distributed and annularly arrayed extension rods 74 are integrally formed at the bottom end face of the screw member 2. Densely distributed crushing teeth 75 are integrally formed and arrayed at the bottoms of the screw member 2 and the extension rods 74. The cleaning assembly 8 includes a liquid pump 81, a delivery pipe 82 and a spray head member 83. The liquid pump 81 is arranged on the outer wall of the cylinder 1.

[0022] Working principle: Pour dry tung seeds into the cylinder body 1 through the feeding hopper 3, control the start of the reduction motor 5 to drive the screw member 2 to rotate. The screw member 2 cooperates with the cylinder body 1 to send the dry tung seeds to the bottom of the cylinder body 1 and extrude the dry tung seeds downward. The dry tung seeds are pressed under the extrusion of the screw member 2 and the interception of the primary filter screen 73. At the same time, the extension rod 74 and the crushing teeth 75 rotate, and the crushing teeth 75 crush the dry tung seeds. The pressed tung oil flows out from the bottom of the discharge cylinder 71 through the primary filter screen 73 and the secondary filter screen 72; after pressing, the discharge cylinder 71 can be removed to take out the oil cake; Connect the input end of the liquid pump 81 to the external cleaning water through a pipeline, control the start of the liquid pump 81, and spray it into the cylinder body 1 through the delivery pipe 82 by the spray head member 83 to clean the internal components.
