Detailed Implementation

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0018] See attached document Figures 1-4 This utility model provides a cold-pressing extraction device for pecan oil, including a support 100. A crushing mechanism for crushing wild pecans is provided on one side of the top of the outer wall of the support 100. The crushing mechanism includes a feeding box 210, and a crushing box 200 is integrally fixed to the top of the outer wall of the feeding box 210. A hopper is provided above the crushing roller 230 in the crushing box 200, which can collect pecans and allow them to fall onto the crushing roller 230. Crushing rollers 230 are rotatably connected to the front and rear ends of the inner wall of the crushing box 200 via bearing seats. A transmission gear set 220 is rotatably connected to the front end of the outer wall of the support 100 at a position corresponding to one of the crushing rollers 230. The two transmission gear sets 220 mesh with each other. The rear ends of the transmission gear sets 220 pass through the front end of the inner wall of the support 100 and are fixed to the front end of the crushing roller 230. A servo motor 231 is fixed to the rear end of the outer wall of the support 100 at a position corresponding to any one of the crushing rollers 230. The output shaft of the servo motor 231 is fixedly connected to the rear end of the outer wall of the crushing roller 230. Specifically, after being powered on, the servo motor 231 can drive the crushing roller 230 connected to it to rotate. When the crushing roller 230 rotates, it can drive another crushing roller 230 to rotate simultaneously through the meshing transmission gear set 220, so that the two crushing rollers 230 rotate simultaneously to crush the walnuts. The driving principle of the servo motor 231 is that the operator or control system sends an on / off or speed adjustment control signal, and then the control signal enters the driver (such as a frequency converter, starter, servo driver or contactor control circuit). The controller adjusts the current, voltage and frequency of the motor according to the instruction, thereby controlling the speed of the motor. The sensor on the motor provides real-time position and speed feedback to the controller, and the controller adjusts the output to achieve precise control. The controller model of the motor can be selected from the Siemens V20 or V20S series. A crushing box 200 is installed at the center of the top of the outer wall of the support 100. Inside the crushing box 200 is an oil pressing mechanism for pressing oil from wild walnuts. The oil pressing mechanism includes a support plate 320, which is slidably connected to the inner wall of the press 300. A hydraulic rod system 310 is installed at the top of the outer wall of the press 300 to drive the support plate 320 to move up and down. The hydraulic rod system 310 includes a hydraulic pump, hydraulic rods, control valves, oil lines, a support, and guide rails. During operation, the hydraulic pump provides pressure, and the directional control valve adjusts the oil flow. The hydraulic cylinder pushes the piston and hydraulic rod in the oil cylinder, thereby moving the workpiece up and down. The operator can switch the control valve to realize the extension and retraction of the hydraulic rod through manual buttons or remote PLC control circuit. The circuit control principle is to use the on and off of the solenoid valve coil to control the oil flow. Combined with button switches, relays and limit switches, the hydraulic rod can be raised and lowered automatically or manually to ensure safe and efficient operation. The specific extension and retraction control principle is as follows: When the operator presses the "raise" button, the control circuit activates the corresponding solenoid valve coil, switches the hydraulic oil flow to one port of the oil cylinder, the oil cylinder extends, and moves the workpiece upward. Press the "Lower" button to switch the direction of the solenoid valve, the oil flows to the opposite end, the cylinder retracts, and the workpiece moves downward.

[0019] Release the button, the solenoid valve returns to its original state, stops the flow of hydraulic oil, and the hydraulic rod maintains its current position; the bottom output shaft of the hydraulic rod system 310 passes through the top of the inner wall of the press 300 and is fixed to the top of the outer wall of the support plate 320. The bottom of the outer wall of the support plate 320 is integrally fixed with a pressing head 321 for pressing wild walnuts. A weight-increasing water tank 330 is placed above the top of the outer wall of the support plate 320 and outside the hydraulic rod system 310. The hydraulic rod system 310 can drive the support plate 320 to move up and down under the action of the hydraulic cylinder, so that the pressing head 321 can move down to press the walnuts in the pressing storage box 240 for oil extraction. The weight-increasing water tank 330 is an overall ring structure, and its inner circle can be set outside the hydraulic rod. After the pressing head 321 extends into the pressing storage box 240, the weight-increasing water tank 330 can increase the weight of the support plate 320 by supplying water, thereby improving the oil extraction effect of the pressing head 321 on the walnuts. A water storage tank 400 is installed on one side of the outer wall of the support 100. A water pump 410 is installed at both the inlet and outlet of the top of the outer wall of the water storage tank 400. The water delivery ends of the water pumps 410 are connected to both sides of the top of the outer wall of the weight-adding water tank 330 via inlet and outlet pipes. The water storage tank 400 can be replenished and pumped from the weight-adding water tank 330 by the water pumps 410. The inlet and outlet pipes can be flexible, allowing for vertical movement of the weight-adding water tank 330. The support plate 320 and the crusher... Below each box 200 is a pressing and storage box 240 for holding wild walnuts. The top of the outer wall of the pressing and storage box 240 has a concave pressing groove. The outer front end of the support 100 and the position in front of the pressing and storage box 240 are all equipped with a limiting plate 500. The rear end of the outer wall of the limiting plate 500 is fixed with a clamping block. The limiting plate 500 can be fixed to the front end of the outer wall of the press 300 by bolts. It can limit the position of the pressing and storage box 240 during oil pressing.

[0020] The usage process of this utility model is as follows: Those skilled in the art can first assemble the device according to the above description, then connect all electrical equipment to an external power supply, and control the operation of the device through an external controller. The control programs of all electrical equipment are edited by the production personnel in advance before production. This utility model does not make any technical improvements here, but only assumes that it can normally meet the needs of personnel. First, the operator can take out the pressing storage box 240 and insert it into the feeding box 210. Then, the operator can turn on the servo motor 231 to drive the crushing roller 230 to rotate. At this time, the operator can pour the pecans into the crushing box 200. The crushing box 200 is equipped with a material gathering hopper located above the crushing roller 230. The material gathering hopper can ensure that the pecans fall evenly between the crushing rollers 230. The rotating crushing roller 230 can crush the pecans. The crushed pecans can then fall into the concave pressing groove on the pressing storage box 240. After completion, the operator can insert the pressing storage box 240 into the press 300, then remove the limiting plate 500 and fix the limiting plate 500 to the front end of the outer wall of the press 300 with bolts, so that the limiting plate 500 can limit the position of the pressing storage box 240. After completion, the operator can use the hydraulic cylinder to control the hydraulic rod to drive the bearing plate 320 to move downward, so that the pressing head 321 can press against the walnuts on the pressing storage box 240. At the same time, the water pump 410 can deliver water in the water storage tank 400 to the weight-increasing water tank 330, thereby increasing the weight on the top of the bearing plate 320. With the hydraulic rod system 310, the oil pressing effect of the walnuts can be improved, and the pressed walnut oil can be discharged through the oil discharge end at the bottom of the support 100. After the oil pressing is completed, another water pump 410 can draw the water in the weight-adding water tank 330 back to the storage tank 400. Then the hydraulic rod system 310 can retract to pull the bearing plate 320 upward, and the personnel can then pull out the pressing storage box 240 and place a new pressing storage box 240.
