A transmission plate 205 is fixedly welded on the pillar 207 directly above the crushing mechanism 3, and the transmission plate 205 is inclined from top to bottom toward the meshing center of the first crushing roller 302 and the second crushing roller 306. The top of the transmission plate 205 is located on the lower side of the bottom surface of the support push plate 209, and buffer spring rods 206 are fixedly installed on both sides of the top surface of the transmission plate 205, and a contact switch is embedded in the center of the buffer spring rod 206;

[0040] When in use, the oil cake is first placed into the extrusion barrel 105, and then the extrusion cylinder 103 is started, so that the extrusion cylinder 103 pushes the extrusion plate 104 to move into the extrusion barrel 105, and the oil contained in the oil cake is squeezed out by the extrusion plate 104 and the support push plate 209, and is discharged from the oil outlet hole on the side of the extrusion barrel 105, dripping into the drainage groove 106, and along the drainage groove 106 through the oil discharge hole 107 to the top surface of the oil collecting plate 108, and finally flows into the oil storage barrel 203 for collection, thereby improving the oil yield. Avoid waste of oil; then start the supporting cylinder 204 to contract downward to transfer the extruded oil cake downward to separate from the inside of the extrusion cylinder 105. At the same time, the bottom surface of the supporting push plate 209 will gradually approach the buffer spring rod 206 during the movement, until the buffer spring rod 206 is squeezed and the contact switch inside it is pressed, so that the side push cylinder 208 starts to push the oil cake on the top surface of the supporting push plate 209, so that it separates from the surface of the supporting push plate 209, slides along the surface of the transmission disk 205 to the top of the crushing mechanism 3, and enters the crushing mechanism 3 to be crushed.

[0041] In order to crush the compressed oil cake, the crushing mechanism 3 includes a crushing bin 301, which is fixedly installed on the top surface of the support base 201 away from the side of the pillar 207 through a bracket, and the first crushing roller 302 and the second crushing roller 306 are rotatably embedded in the top of the crushing bin 301, and the first crushing roller 302 and the second crushing roller 306 are meshed. The rotating shaft of the first crushing roller 302 passes through the crushing bin 301 and is rotatably sleeved with a driven wheel 307. The support base 201 is fixedly installed with a driving motor 308 on the bottom surface of the crushing bin 301, and the power output end of the driving motor 308 is rotatably sleeved with a driving wheel 309, which is connected to the driven wheel 307 through a belt, and the first crushing roller 302 and the second crushing roller 306 are connected through gear transmission. A discharge barrel 303 is protruded from the center of the side of the crushing bin 301, and the discharge barrel 303 is connected with the bottom end of the crushing bin 301.

[0042] When the oil meal cake enters between the first crushing roller 302 and the second crushing roller 306, the driving motor 308 starts, driving the driving wheel 309 to rotate, and then driving the first crushing roller 302 to rotate through the driven wheel 307. The first crushing roller 302 and the second crushing roller 306 are meshed through gears so that the first crushing roller 302 and the second crushing roller 306 rotate in opposite directions to crush the oil meal cake, and after the oil meal cake is crushed, it enters the crushing bin 301.

[0043] In order to perform secondary crushing of the oil meal, a cutting blade 312 is rotatably connected to the center of the bottom surface of the crushing bin 301 through a driving shaft 311, and the cutting edge of the cutting blade 312 is tilted upward. There are four cutting blades 312, and the four cutting blades 312 are evenly surrounded by the top of the driving shaft 311. The driving shaft 311 passes through the center of the bottom surface of the crushing bin 301 and is rotatably sleeved with a driven bevel gear 314. The driving motor 308 is a double-shaft motor, and the power output end on the other side of the driving motor 308 is rotatably sleeved with an active bevel gear 310, and the active bevel gear 310 is meshed with the driven bevel gear 314. A cleaning plate 313 is vertically welded to the bottom surface of the cutting blade 312, and the bottom surface of the cleaning plate 313 is tangent to the inner bottom surface of the crushing bin 301.

[0044] When the driving motor 308 is working, it will also drive the active bevel gear 310 to rotate. The active bevel gear 310 and the driven bevel gear 314 are meshed, so that the horizontal rotation force can be converted into a vertical rotation force, and then the cutting blade 312 can be driven to perform secondary crushing on the oil meal after the initial crushing. At the same time, the cleaning plate 313 can push the oil meal deposited on the bottom surface of the crushing bin 301 to facilitate its transmission to the outside.

[0045] In order to facilitate the transmission of the crushed oil cake, a rotating motor 305 is fixedly installed on the top surface of the end of the support base 201 through a bracket, and a spiral discharge rod 304 is rotatably connected to the power output end of the rotating motor 305. The spiral discharge rod 304 penetrates the inner center of the discharge barrel 303 and extends to the inner side wall of the crushing bin 301. The side of the spiral discharge rod 304 is tangent to the inner wall of the discharge barrel 303. The length of the spiral discharge rod 304 is greater than that of the discharge barrel 303, so that the spiral discharge rod 304 is exposed outside the discharge barrel 303, which is convenient for the discharge of the oil cake.

[0046] After being crushed, the oil meal enters the discharge barrel 303 under the push of the cleaning plate 313. At the same time, the spiral discharge rod 304 is driven by the rotating motor 305 to rotate inside the spiral discharge rod 304, so that the oil meal can be quickly discharged from the crushing bin 301, avoiding the accumulation of oil meal in the crushing bin 301 and improving the crushing efficiency of the crushing mechanism 3.

[0047] In order to facilitate the transportation of the oil meal, a collecting mechanism 4 is also included. The collecting mechanism 4 includes a collecting box 401. The collecting box 401 is fixedly installed on the top surface of the support base 201 close to the rotating motor 305. The collecting box 401 is located directly below the discharge barrel 303. The collecting box 401 is a rectangular box body. A notch is opened on one side of the top surface of the collecting box 401. The notch is located directly below the exposed part of the spiral discharge rod 304. A discharging movable door 402 is rotatably embedded on the side of the collecting box 401 away from the notch. A torsion spring is connected to the rotating shaft sleeve between the movable door 402 and the collection box 401, and a push plate 403 is embedded in the collection box 401 on the surface of one side of the notch in a tangent manner; a driving cylinder 404 is fixedly installed on the top surface of the end of the support base 201 just below the rotating motor 305, and the power output end of the driving cylinder 404 passes through the push plate 403 and is fixedly welded with the push plate 403, and the push plate 403 is slidably embedded in the collection box 401 and tangent to the inner wall of the collection box 401, and the top of the push plate 403 is cut into an arc surface;

[0048] When the oil meal is crushed by the crushing mechanism 3 and falls into the collecting box 401 through the notch, the top of the push plate 403 is cut into an arc shape to facilitate the oil meal to fall and avoid accumulation on the top of the push plate 403. Then, the driving cylinder 404 is driven to push the push plate 403 in a cycle under a predetermined program, and the crushing mechanism 3 stops working at the same time to prevent the oil meal from falling to the rear side of the push plate 403, so that the push plate 403 can push the oil meal to accumulate and move to the side of the discharge movable door 402 until the oil meal is discharged. The pushing plate 403 and the discharge movable door 402 squeeze the oil meal therebetween until the extrusion thrust is greater than the reverse elastic force of the torsion spring between the collecting box 401 and the discharge movable door 402, and then the oil meal squeezed into blocks can be pushed out of the collecting box 401 from one end of the discharge movable door 402 for easy storage and transportation. At the same time, the pushing plate 403 returns, and the discharge movable door 402 re-seals the side of the collecting box 401 under the action of the torsion spring, so as to facilitate the oil meal to be shaped and extruded again.

[0049] When the present invention is used, the oil cake is first placed in the extrusion cylinder 105, and then the extrusion cylinder 103 is started, so that the extrusion cylinder 103 pushes the extrusion plate 104 to move into the extrusion cylinder 105, and the extrusion plate 104 and the support push plate 209 are squeezed against each other, so that the oil contained in the oil cake is squeezed out and discharged from the oil outlet hole on the side of the extrusion cylinder 105, dripping into the drainage groove 106, and along the drainage groove 106, through the oil discharge hole 107, it is collected to the top surface of the oil collecting plate 108, and finally flows into the oil collecting plate 108. The oil is collected inside the oil storage barrel 203 to improve the oil yield and avoid oil waste; then the support cylinder 204 is started to contract downward to transfer the oil cake extruded in the form of a cake downward to separate from the inside of the extrusion cylinder 105, and at the same time, the bottom surface of the support push plate 209 gradually approaches the buffer spring rod 206 during the movement, until the buffer spring rod 206 is squeezed and the contact switch inside is pressed, so that the side push cylinder 208 is started to push the oil cake on the top surface of the support push plate 209 to separate from the surface of the support push plate 209;

[0050] Secondly, when the oil cake enters between the first crushing roller 302 and the second crushing roller 306, the driving motor 308 is started, driving the driving wheel 309 to rotate, and then driving the first crushing roller 302 to rotate through the driven wheel 307, and the first crushing roller 302 and the second crushing roller 306 are meshed through gears, so that the first crushing roller 302 and the second crushing roller 306 rotate in opposite directions to crush the oil cake, and the crushed oil cake enters the crushing bin 301; immediately when the driving motor 308 is working, it will also drive the driving bevel gear 310 to rotate, and the driving bevel gear 310 and the driven bevel gear 314 are meshed, so that the horizontal rotation force can be converted into a vertical rotation force, and then the cutting blade 312 can be driven to perform a secondary crushing of the oil cake after the initial crushing, and at the same time, the cleaning plate 313 can push the oil cake deposited on the bottom surface of the crushing bin 301 to facilitate its transmission to the outside;

[0051] Finally, after the crushing, the oil meal enters the discharge barrel 303 under the push of the cleaning plate 313, and at the same time, the spiral discharge rod 304 is driven by the rotating motor 305 to rotate inside the spiral discharge rod 304, so that the oil meal can be quickly discharged from the crushing bin 301 to avoid the oil meal accumulation inside the crushing bin 301. Then, the oil meal falls into the collecting box 401 through the notch therein, and the top of the push plate 403 is cut into an arc shape to facilitate the falling of the oil meal to avoid accumulation on the top of the push plate 403. Then, the driving cylinder 404 circulates and pushes the push plate 403 under a predetermined program, and at the same time, the crushing mechanism 3 stops working to avoid oil meal accumulation. The meal falls to the rear side of the push plate 403, so that the push plate 403 can push the oil-meal to be piled together and move toward the side of the discharge movable door 402, until the push plate 403 and the discharge movable door 402 squeeze the oil-meal between them, until the squeezing thrust is greater than the reverse elastic force of the torsion spring between the collection box 401 and the discharge movable door 402, and then the oil-meal squeezed into blocks can be pushed out of the collection box 401 from one end of the discharge movable door 402 for easy storage and transportation. At the same time, the push plate 403 returns, and the discharge movable door 402 re-seals the side of the collection box 401 under the action of the torsion spring, so as to facilitate the shaping and squeezing of the oil-meal again.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
