[0026] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0027] Please refer to the following: Figures 1 to 2The present invention will now describe a corn crusher. The corn crusher includes: a housing 1, a transmission assembly, and a crushing assembly. The outer wall of the housing 1 has a feed inlet 101, and a feed hopper 102 is installed at the feed inlet 101. The transmission assembly includes two transmission rollers arranged parallel to each other in the horizontal direction. The transmission rollers include an outer roller 201 and an inner roller 202 arranged coaxially. The outer roller 201 is rotatably installed inside the housing 1. The two outer rollers 201 are located below the feed inlet 101 and rotate in opposite directions for conveying corn ears. The outer circumferential surface of the outer roller 201 is provided with a piercing knife 203 and a first discharge hole 204. The piercing knife 203 is used to cut the corn husks on the surface of the corn ears. The first discharge hole 204 communicates with the inner cavity of the outer roller 201. One end of the outer roller 201 is provided with a first discharge port 205 for discharging corn husks. The inner roller 202 is rotatably connected to the outer roller 201 and rotates in the opposite direction to the outer roller 201. The inner roller 202 penetrates the inner cavity of the outer roller 201. The outer circumferential surface of the inner roller 202 is provided with a first spiral conveyor 206 and a second discharge hole. The first spiral conveyor 206 is located inside the outer roller 201 and contacts the inner circumferential surface of the outer roller 201. The first spiral conveyor 206 is used to transport corn husks. The second discharge hole 207 is connected to the inner cavity of the inner roller 202 and is located on the outside of the outer roller 201. After peeling, the corn ears enter the inner cavity of the inner roller 202 through the second discharge hole 207. One end of the inner roller 202 is provided with a second discharge port 208 for discharging concentrated feed. The crushing assembly includes a first support frame 301 and a crushing roller 302. The first support frame 301 is rotatably mounted on the inner roller 202. One end of the first support frame 301 extends into the inner cavity of the inner roller 202. The first support frame 301 and the inner roller 202 are coaxially arranged and rotate in opposite directions. The crushing roller 302 is fixedly mounted on the first support frame 301. The crushing roller 302 corresponds to the second discharge hole 207 and is used to crush the peeled corn ears to obtain concentrated feed.

[0028] This embodiment provides a corn crusher, which, compared with the prior art, features a feed inlet 101 on the side wall of the housing 1, with a feed hopper 102 installed at the feed inlet 101. A conveying channel for accommodating corn ears is formed on the upper part of the side of the two outer rollers 201 that are close to each other. The corn ears enter between the two outer rollers 201 from the feed hopper 102. The two outer rollers 201 rotate, driving the corn ears forward. Simultaneously, the piercing blades 203 on the outer rollers 201 cut the corn husks. The cut corn husks enter the interior of the outer rollers 201 through the first discharge hole 204. The inner roller 202 penetrates the inner cavity of the outer roller 201 and rotates in the opposite direction to the outer roller 201. The first spiral conveyor 206 on the outer circumference of the inner roller 202 contacts the inner circumference of the outer roller 201. The inner roller 202 drives the first spiral conveyor 206 to rotate synchronously. The first spiral conveyor 206 transports the corn husks that have entered the outer roller 201 to the first discharge port 205 for discharge, thus completing the peeling of the corn cobs. After peeling, the corn cobs fall into the inner roller 202 from the second discharge hole 207 on the inner roller 202 under the transmission action of the two outer rollers 201. One end of the first support frame 301 is fixedly installed on the outside of the housing 1, and the other end extends into the inner cavity of the inner roller 202. The crushing roller 302 is installed on the first support frame 301 and corresponds to the second discharge port. The crushing roller 302 crushes the peeled corn cobs to obtain concentrated feed, which is discharged through the second discharge port 208 at one end of the inner roller 202. The corn crusher of this application, through the cooperation of the transmission component and the crushing component, has the functions of peeling and crushing corn ears, which greatly improves the processing efficiency of concentrated feed.

[0029] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6One end of the outer roller 201 is located outside the housing 1, and the other end is located inside the housing 1. The first discharge port 205 is located at the end of the outer roller 201 opposite to the direction of corn cob transmission, that is, the corn cob is transmitted to the right on the outer roller 201, and the first discharge port 205 is located at the left end of the outer roller 201. There are multiple piercing knives 203 and first discharge holes 204, which are arranged in a spiral along the axial direction of the outer roller 201. The height of the piercing knives 203 is 5mm-10mm, which ensures that the piercing knives 203 can pierce the corn husks. At the same time, the corn cob moves forward (to the right) under the action of the outer roller 201 and the piercing knives 203. The piercing knives 203 only pierce the corn husks. After being pierced, the free end of the corn husks enters the inner cavity of the outer roller 201. The first spiral conveyor 206 squeezes the corn husks against the inner wall of the outer roller 201 and drives the corn husks to move towards the second discharge port 208, finally separating the corn husks from the corn cob. A first motor 103 is mounted on the outside of the housing 1. The first motor 103 drives the outer roller 201 to rotate around its axis via a belt 104. Both ends of the inner roller 202 pass through the outer roller 201. Both ends of the inner roller 202 extend to the outside of the housing 1. A first screw conveyor 206 corresponds to the first discharge hole 204 and extends towards the first discharge port 205. There are multiple second discharge holes 207, evenly arranged along the circumference of the inner roller 202. The second discharge holes 207 are located on the outer side of the right end of the outer roller 201. Peeled corn ears fall from the outer roller 201 through the second discharge holes 207 into the inner roller 202. A second motor 105 is mounted on the outside of the housing 1. The second motor 105 drives the inner roller 202 to rotate around its axis via gears. The crushing roller 302 includes two crushing drums 303, which rotate in opposite directions. The rotation axis of the crushing drum 303 is parallel to the steering axis of the inner drum 202. A third motor 107 for driving the crushing drum 303 to rotate is mounted on the first support frame 301. The third motor 107 drives the crushing drum 303 to rotate through gear transmission. The peeled corn cobs are crushed into fine particles by the two crushing drums 303. The crushed corn particles fall downwards through the gap between the two crushing drums 303. The crushing roller 302 has two sets, which are arranged vertically. The gap between the two crushing drums 303 located below is smaller than the gap between the two crushing drums 303 located above.

[0030] In some embodiments, please refer to Figures 1 to 2A second spiral conveyor 209 is installed inside the inner drum 202. The second spiral conveyor 209 is fixedly installed on the inner circumferential surface of the inner drum 202 and arranged along the axial direction of the inner drum 202, used to convey the concentrated feed inside the inner drum 202 to the second discharge port 208. In this embodiment, the second spiral conveyor 209 is fixedly installed on the inner circumferential surface of the inner drum 202, and is located between the crushing assembly and the second discharge port 208. After the corn cobs are crushed by the crushing assembly, concentrated feed is obtained. Under the action of the second spiral conveyor 209, the concentrated feed is conveyed to the second discharge port 208 and discharged through the second discharge port 208. The second discharge port 208 is located at the center of the end face of the inner drum 202.

[0031] In some embodiments, please refer to Figure 1 and Figure 2 A filter baffle 210 is installed between the second spiral conveyor 209 and the first support frame 301. The filter baffle 210 is used to filter the concentrate feed. In this embodiment, the filter baffle 210 has a mesh structure and is perpendicular to the axis of the inner roller 202, dividing the inner cavity of the inner roller 202 into a transmission cavity and a crushing cavity. The second spiral conveyor 209 is located in the transmission cavity, and the first support frame 301 and the crushing roller 302 are located in the crushing cavity. The second discharge hole 207 is connected to the crushing cavity. Corn kernels that meet the particle size requirements of concentrate feed can enter the transmission cavity through the filter baffle 210, while corn kernels larger than the particle size requirements of concentrate feed will continue to be crushed in the crushing cavity until they meet the product requirements.

[0032] In some embodiments, please refer to Figure 1 and Figure 2 A heating rod 211 is installed inside the inner drum 202, and the heating rod 211 is arranged along the axial direction of the inner drum 202. In this embodiment, the concentrate feed processed by the existing corn crusher has a high moisture content. In order to facilitate transportation and storage, the concentrate feed needs to be dried again using a dryer, which greatly reduces production efficiency. To solve the above problem, a heating rod 211 is installed inside the inner drum 202, and the heating rod 211 is arranged along the axial direction of the inner drum 202. The second spiral conveyor 209 has a corresponding clearance hole for the heating rod 211 to pass through. The heating rod 211 can dry the concentrate feed inside the inner drum 202, thereby reducing the moisture content of the concentrate feed. During the conveying process of the concentrate feed, the second spiral conveyor 209 can also cause the concentrate feed to tumble, so that the concentrate feed can fully contact the heating rod 211, further improving the drying effect.

[0033] In some embodiments, please refer to Figure 1A tail cover 212 is fixedly installed on the outside of the housing 1. The tail cover 212 is fitted at the first discharge port 205 and rotatably connected to the outer roller 201. A third discharge port 213 is opened at the bottom of the tail cover 212. In this embodiment, the tail cover 212 is fixedly installed on the outer wall of the housing 1 by a connecting plate 214. The tail cover 212 is fitted at the first discharge port 205 of the outer roller 201, and a third discharge port 213 is opened at the bottom of the tail cover 212. Corn husks enter the tail cover 212 through the first discharge port 205 and are then discharged to the outside through the third discharge port 213. Since the third discharge port 213 is fixed relative to the housing 1, the operator can place a collection container below the third discharge port 213 to facilitate the collection and processing of corn husks.

[0034] In some embodiments, please refer to Figure 1 A blower 215 is fixedly installed on the tail cover 212, and the blower 215 creates a negative pressure in the space between the outer roller 201 and the inner roller 202. In this embodiment, the blower 215 is installed on the tail cover 212 and is located outside the first discharge port 205. The blower 215 can be inside or outside the tail cover 212, as long as it can create a negative pressure in the space between the outer roller 201 and the inner roller 202. After the piercing knife 203 pierces the corn husk on the corn cob, the free end of the corn husk will automatically enter the space between the outer roller 201 and the inner roller 202 (i.e., the spiral channel formed by the first spiral conveyor 206) under the action of pressure, so that all the corn husk can smoothly enter the outer roller 201.

[0035] In some embodiments, please refer to Figure 1 and Figure 3 A cutting blade 216 is installed at the end of the outer roller 201 away from the feed inlet 101. The cutting blade 216 is used to cut the corn cobs. In this embodiment, the cutting blade 216 is fixedly installed at the end of the outer roller 201 away from the feed inlet 101 (i.e., the end of the outer roller 201 near the second discharge hole 207). There are multiple cutting blades 216, evenly arranged along the circumference of the outer roller 201. The cutting blades 216 on the two outer rollers 201 are staggered. When the peeled corn cobs move to the end of the outer roller 201 near the second discharge hole 207, the cutting blade 216 cuts the corn cobs into slices. The sliced ​​corn falls downwards and enters the inner cavity of the inner roller 202 through the second discharge hole 207. After the cutting blade 216 cuts the corn cobs into slices, it is convenient for the crushing component to crush the corn cobs, thereby improving the production efficiency of concentrated feed.

[0036] In some embodiments, please refer to Figure 1 and Figure 4A scraper 217 is fixedly installed on the outer circumferential surface of the inner roller 202. The scraper 217 and the second discharge hole 207 are arranged alternately along the circumference of the inner roller 202. In this embodiment, the scraper 217 is a rectangular plate, and there are multiple scrapers 217 arranged radially on the outer wall of the inner roller 202. The second discharge hole 207 is a rectangular hole, and the length direction of the second discharge hole 207 is parallel to the axial direction of the inner roller 202. The scraper 217 is tangent to the long side of the second discharge hole 207. During the rotation of the inner drum 202, the position of the second discharge hole 207 is constantly changing. Therefore, some of the flaky corn falling from the outer drum 201 will fall directly into the inner cavity of the inner drum 202 through the second discharge hole 207, while some will fall to the outside of the inner drum 202. The crushed corn kernels will also fall to the outside of the inner drum 202 through the second discharge hole 207. The corn that falls to the outside of the inner drum 202 is still in the cavity of the shell 1. Therefore, in order to avoid waste, the scraper 217 will rotate under the drive of the inner drum 202 to collect the corn that falls to the outside of the inner drum 202 and put it back into the inner drum 202 through the second discharge hole 207.

[0037] In some embodiments, please refer to Figure 1 and Figure 3 A support baffle 218 is installed inside the housing 1. The support baffle 218 is perpendicular to the axis of the outer roller 201 and is used to support the outer roller 201. In this embodiment, the support baffle 218 is located at one end of the outer roller 201 near the second discharge hole 207, supporting the outer roller 201 and thus improving its stability. The top surface of the support baffle 218 is on the same horizontal plane as the axis of the outer roller 201. The side wall of the support baffle 218 is tangent to the side wall of the cutting blade 216. The support baffle 218 divides the inner cavity of the housing 1 into two cavities, left and right. The scraper 217 is located in the left cavity of the housing 1, thereby preventing corn falling outside the inner roller 202 from being too far from the scraper 217, so that the scraper 217 can collect as much corn outside the inner roller 202 as possible.

[0038] In some embodiments, please refer to Figure 1 and Figure 2The housing 1 contains a roller assembly located above two conveying rollers. The roller assembly includes a second support frame 401 and a drive wheel 402. The second support frame 401 is vertically fixed to the top of the housing 1, and the drive wheel 402 is rotatably mounted on the bottom of the second support frame 401. The rotation axis of the drive wheel 402 is perpendicular to the rotation axis of the outer roller 201, and the lower end face of the drive wheel 402 contacts the corn cob. In this embodiment, multiple roller assemblies are arranged along the axial direction of the conveying rollers. An elastic element 403, a compression spring, is mounted on the top of the second support frame 401. The upper end of the elastic element 403 is fixed to the top of the housing 1, and the elastic element 403 applies a downward force to the second support frame 401. A fourth motor 404 and a support shaft 405 are also mounted on the second support frame 401. The drive wheel 402 is fixedly mounted on the support shaft 405, and the support shaft 405 is fixedly connected to the output shaft of the fourth motor 404. The fourth motor 404 drives the drive wheel 402 to rotate around its axis. The axis of the drive wheel 402 is perpendicular to the axis of the transmission roller. The drive wheel 402 is located directly above the center line between the two transmission rollers. Under the action of the elastic element 403, the drive wheel 402 applies a downward force to the corn cobs on the transmission roller, thereby ensuring the stability of the corn cobs during the cutting process by the cutter 216. Because the elastic element 403 is installed between the housing 1 and the second support frame 401, corn cobs of different sizes can easily pass under the drive wheel 402. Driven by the fourth motor 404, the drive wheel 402 provides forward motion power for the corn cobs, thereby ensuring the transmission efficiency of the corn cobs on the transmission roller.

[0039] 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, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
