[0021] To further elaborate on the technical means and effects adopted by the present utility model to achieve the intended utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific embodiments, structures, features and their effects according to the present utility model as follows.

[0022] As shown in the attached Figures 1-4 figures, the present utility model discloses a small pneumatic corn husker, which includes a turntable 1, a root-opening device arranged on the bottom surface of the turntable 1 and rotating together with the turntable 1, and a feeding device 8, a clamping device and a peeling device arranged on one side of the turntable 1. The feeding device 8, the clamping device and the peeling device are arranged in sequence. The root-opening device rotates with the turntable 1 and corresponds to the clamping device and the peeling device in position in sequence. The feeding device 8 is used for feeding. When the material is transported to the position between the root-opening device and the clamping device, the clamping device acts to push the corn onto the root-opening device.

[0023] The structure of the feeding device 8 is more reflected in the prior art and can realize the feeding of fresh corn and simple root cutting and tip cutting operations. For example, the material conveying device described in the utility model patent with the publication number CN220197857U.

[0024] Specifically, the root-opening device is arranged along the radial direction of the turntable 1 and includes a sliding sleeve 14 slidably installed on the bottom surface of the turntable 1 through a light bar 13, a root sleeve 15 fixedly arranged on the sliding sleeve 14, and a root-opening drill device arranged at the corresponding position behind the root sleeve 15. The root-opening drill device is also installed on the turntable 1. An upward connecting rod is arranged on the sliding sleeve 14, and a pushing device is installed on the connecting rod. A long groove is arranged along the radial direction on the turntable 1. The connecting rod passes upward through the long groove, and the pushing device is located on the top surface of the turntable 1.

[0025] Preferably, the light bar 13 is fixedly installed on the bottom surface of the turntable 1, and the sliding sleeve 14 is installed on the light bar 13. The root-opening drill device and the root sleeve 15 are on the same axis.

[0026] The pushing device includes a pushing sleeve 16 fixedly installed on the top surface of the turntable 1 and a sliding rod 17 sleeved in the pushing sleeve 16. One end of the sliding rod 17 is fixedly connected with the connecting rod. A first spring 18 is arranged on the sliding rod 17 and between the pushing sleeve 16 and the connecting rod. In the initial state, due to the acting force of the first spring 18, the sliding sleeve 14 is in the outermost state, and there is a certain distance between the root sleeve 15 and the root-opening drill device.

[0027] The root-opening drill device includes a root-opening sleeve 21 fixedly installed on the bottom surface of the turntable 1, a root-opening rotating shaft 22 arranged inside the root-opening sleeve 21, a root-opening drill 23 arranged at the front end of the root-opening rotating shaft 22, and a gear arranged at the end of the root-opening rotating shaft 22. This gear is connected to the driving device as the power input for the rotation of the root-opening rotating shaft 22. The root-opening drill 23 of the present utility model has been more embodied in the prior art. For example, the positioning drill in the utility model patent with the publication number CN219679711U can play a role in positioning corn, and at the same time can cut open the root of the corn to facilitate the peeling operation. The specific structure will not be elaborated here.

[0028] The clamping device includes a clamping fixed frame 2, a clamping cylinder 3 arranged on the clamping fixed frame 2, a clamping sleeve 10 fixed on the piston rod of the clamping cylinder 3, a clamping rod arranged inside the clamping sleeve 10, a tip sleeve 11 fixedly installed at the end of the clamping rod, and a third spring 12 arranged between the clamping sleeve 10 and the tip sleeve 11. The clamping cylinder 3 is installed on the top surface of the fixed frame 2, and the clamping sleeve 10 is located below the fixed frame 2. A long groove is also provided on the fixed frame 2, and the clamping sleeve 10 and the piston rod are connected together through a connecting rod arranged in the long groove. The moving direction of the piston rod of the clamping cylinder 3 is consistent with the radial direction of the turntable 1. When the fresh corn is transported by the feeding device 8 to the position between the root-opening device and the clamping device, the clamping cylinder 3 acts, and the tip sleeve 11 cooperates with one end of the corn, pushing the corn towards the root-opening device side, so that the other end of the corn cooperates with the root sleeve 15. The clamping cylinder 3 continues to move, driving the root sleeve 15 to move towards the root-opening drill 23 together until the root-opening drill 23 passes through the root sleeve 15 and inserts into the corn. After that, the root-opening drill 23 rotates, and the root of the corn can be cut open to facilitate subsequent peeling processing.

[0029] After the corn is in place in cooperation with the root-opening drill 23, in order to prevent the first spring 18 from driving the root sleeve 15 to pull out the corn outward, a limiter is provided on the fixed frame 9 to limit the position of the root sleeve 15. Specifically, a roller 19 is provided at the top of the connecting rod, and the limiter is correspondingly installed on the fixed frame 9. The limiter includes a limit sleeve 25 fixedly installed on the fixed frame 9, a limit rod 20 arranged inside the limit sleeve 25, and a second spring arranged on the limit rod 20. The end of the limit rod 20 is wedge-shaped. When the root sleeve 15 moves inward under the push of the clamping device, the roller 19 comes into contact with the end of the limit rod 20. Under the external force, the limit rod 20 retracts. After the roller 19 passes through the position of the limit rod 20, the limit rod 20 resets to play a limiting role to prevent the root sleeve 15 from moving outward under the action of the pushing device. The radial position of the limiter should correspond to the position of the root-opening drill 23. When the corn moves to the position where it is fully in cooperation with the root-opening drill, the roller 19 just passes through the position of the limit rod 20.

[0030] The peeling device includes a peeling roller 5 disposed below the turntable 1. There are two peeling rollers 5 arranged side by side. A blowing device 4 is provided outside the two peeling rollers 5. The peeling roller 5 is connected to the peeling motor through a chain. The peeling motor drives the two peeling rollers 5 to rotate simultaneously to tear off the corn husks or corn whiskers. The blowing device 4 applies a high-speed air flow to the corn to blow open or blow off the corn husks.

[0031] Preferably, a first slide rail 6 is provided on the fixed frame 9 at a position between the clamping device and the peeling device. The first slide rail 6 is arc-shaped, and the center of the arc coincides with the rotation center of the turntable 1. A second slide rail 7 is provided behind the peeling device. The first slide rail 6 and the second slide rail 7 are smoothly connected in a transitional manner. The second slide rail 7 gradually offsets outward. The roller 19 is located inside the first slide rail 6 and the second slide rail 7. When the turntable 1 rotates, the slide rail and the roller 19 cooperate to play a limiting role. Preferably, a third slide rail is provided inside the second slide rail 7. The shape of the third slide rail corresponds to that of the second slide rail. The roller 19 is located between the second and third slide rails. After the corn passes through the peeling device, under the guiding action of the second and third slide rails, the root sleeve 15 gradually moves outward to pull out the corn from the root drilling tool 23 to achieve blanking.

[0032] The stopper is located at the initial position of the first slide rail 6 and there is a certain gap between them. When the roller 19 is forced to move inward, it moves to a position between the initial position of the first slide rail 6 and the limiting rod 20, compresses the second spring on the limiting rod 20, and causes the limiting rod 20 to retract. Thus, the roller 19 passes through the position between the first slide rail 6 and the stopper. After removing the external force applied to the sleeve 14, under the action of the first spring 18, the roller 19 has a tendency to move outward, but cannot pass through the position between the limiting rod 20 and the first slide rail 6. Thus, the cooperation between the roller 19 and the first slide rail 6 is achieved, so that when the turntable 1 rotates subsequently, the roller 19 moves along the first slide rail 6.

[0033] Generally speaking, according to the processing procedure, the present utility model can be divided into four stations, which are the feeding station where the feeding device 8 is located, the root-opening station where the clamping device is located, the peeling station where the peeling device is located, and the final blanking station. The feeding device 8, the clamping device, and the peeling device are sequentially arranged outside the turntable 1. A root-opening device is provided on the turntable 1, which not only plays a role in root-opening, but also drives the corn to flow between different stations until blanking at the blanking station.

[0034] Preferably, a driving structure for driving the root-opening rotating shaft 22 to rotate should also be provided on the fixing frame. The driving structure includes two driving gears. Both driving gears are located below the turntable 1 and are rotationally connected to the motor through a chain. The two driving gears are respectively located at positions corresponding to the clamping device and the peeling device. When the root-opening device moves to the corresponding position with the turntable 1, the gear at the end of the root-opening rotating shaft 22 is in transmission with the driving gear at the corresponding position, thereby driving the root-opening rotating shaft 22 to rotate for root-opening or skin-throwing operations.

[0035] The processing flow of the present utility model is as follows:

[0036] Place the corn on the feeding device 8. The feeding device 8 transports the corn forward, and preliminary processing of the corn can be carried out during the transportation process, cutting off its roots and tips. As Figure 1 shown in the direction, the tip of the corn needs to be placed facing outward. At this time, the root-opening device corresponds to the clamping device, and the sliding sleeve 14 is in the outermost position;

[0037] When the corn is transported to the position between the root-opening device and the clamping device, the clamping cylinder 3 acts, pushing the tip sleeve 11 towards the corn side until the corn is pushed to the position of the root sleeve 15, and the corn is clamped by the root sleeve 15 and the tip sleeve 11. The tip sleeve 11 continues to move, pushing the root sleeve 15 towards the root drill 23, so that the root drill 23 is inserted into the corn. When the roller 19 passes through the position of the limit rod 20 and stops, the root drill 23 is completely inserted into the corn. Then the root drill 23 rotates to perform a root-opening operation on the corn, cutting open the corn skin at the root of the corn for subsequent peeling operations, and then the tip sleeve 11 retracts to the initial position.

[0038] After the root-opening operation is completed, the turntable 1 drives the root-opening device to rotate, and at the same time transports the corn to the peeling device position. After reaching the peeling device position, the air-blowing device 4 works to blow the corn skin off the corn, and at the same time the two peeling rollers 5 act to clamp the corn skin and tear it off the corn. During the rotation of the turntable 1, the roller 19 disengages from the limit rod 20 and cooperates with the first slide rail 6. Under the action of the first slide rail 6, the sliding sleeve 14 is prevented from moving outwards.

[0039] After the peeling operation is completed, the turntable 1 continues to drive the corn to rotate. The roller 19 disengages from the first slide rail 6 and starts to cooperate with the second and third slide rails. Under the guiding action of the second and third slide rails, the sliding sleeve 14 gradually moves outwards, pushing the corn out of the root drill 23 gradually to complete automatic blanking.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
