Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of corn peeling, in particular to a corn peeling device with a belt type pressure feeder and self-adaptive gap adjustment. BACKGROUND

[0002] In China, corn is generally harvested by harvesting the ear, and the peeling device is a key device of the corn ear combine harvester. After the corn ear is picked, the peeling device is needed to peel the bract of the corn ear. The peeling device has an important influence on the quality of corn harvesting. At the same time, the fresh corn and the seed corn are also harvested by the ear harvesting method, and the integrity of the corn kernel is required to be high during harvesting. The peeling process is the core during harvesting and is the key to affect the harvesting quality of fresh corn and seed corn.

[0003] The corn ear peeling device mainly consists of a pressure feeder and a peeling roller group. The friction and mechanical action between the peeling roller surface and the corn ear make the bract of the corn ear be effectively grabbed and peeled. When the corn ear is grabbed by the peeling roller, the corn ear is prone to be upturned, which will cause the end of the corn ear to be bitten. After the bract is peeled, the naked ear needs to be quickly separated from the peeling device to avoid the corn kernel from being in contact with the peeling roller for a long time and causing loss. In order to generate enough friction between the corn ear and the peeling roller, a pressure feeder needs to be installed above the peeling roller to provide enough pressure to the corn ear, avoid the corn ear from being upturned, and make the corn ear transported on the peeling roller to the discharge port.

[0004] The existing pressure feeder generally adopts the form of a star wheel and an impeller. The gap between the pressure feeder and the peeling roller group is relatively fixed during operation, and the gap cannot be adjusted in real time. When the diameter of the corn ear is too large or too small, the pressure will be too large or insufficient, which will cause the peeling rate of the corn to decrease and the loss rate and damage rate to increase.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below.

[0030] Example 1: As Figures 1-3 The diagram shows a belt conveyor corn peeling device with adaptive gap adjustment, which includes a set of side plates, a peeling assembly 3 and a conveying assembly 4. The peeling assembly 3 and the conveying assembly 4 are installed between the side plates, and the conveying assembly 4 is located above the peeling assembly 3.

[0031] The side plate includes an upper side plate 1 and a lower side plate 2. The upper and lower edges of the upper side plate 1 and the lower side plate 2 are provided with horizontal bends 104. The upper and lower side plates 2 are fixedly connected by adjacent horizontal bends 104. Specifically, corresponding through holes are provided on the horizontal bends 104, and bolts are inserted into the through holes to fix the upper and lower side plates 2 together.

[0032] The upper side plate 1 is also provided with an inspection port, and an inspection window 7 is installed on the inspection port. The lower side of the inspection window 7 is connected to the side plate by a hinge, and the upper end of the inspection window 7 is connected to the side plate by a fastener. The inspection window 7 can be closed and opened by the fastener, which facilitates the maintenance of the peeling device.

[0033] The peeling assembly 3 is fixed on the lower side plate 2 by bolts, the front of the peeling assembly 3 is provided with a transmission device, a feeding port 5 and a distribution wheel 501, and the rear is provided with a throwing wheel 8. The pressing assembly 4 adopts a belt presser and is fixed on the upper side plate 1, so that the belt presser is located above the peeling roller 402 group.

[0034] The feeding end of the gap self-adaptive adjusting belt presser corn peeling device is provided with a feeding port 5, the feeding port 5 is provided with an inclined feeding plate, the feeding port 5 is located above the peeling assembly 3, and the distribution wheel 501 is transversely arranged in the feeding port 5, and the position of the distribution wheel 501 is between the feeding plate and the belt presser. During operation, the corn ears enter the peeling device through the feeding plate, pass through the rotating distribution wheel 501 and enter the rear uniformly.

[0035] As shown in Figure 9 The distribution wheel 501 includes a main shaft 5011, a plurality of groups of material shifting plates 5012 are fixed on the main shaft 5011, each group of material shifting plates 5012 includes four shifting pieces, the shifting pieces are uniformly fixed on the main shaft 5011 with the main shaft 5011 as the center, the two ends of the main shaft 5011 extend outwardly from the side plate, a belt pulley is arranged on the extension of the main shaft 5011, and the belt pulley of the main shaft 5011 is in transmission connection with the belt pulley at the end of the power shaft 6. The main shaft 5011 is connected with the power shaft 6 through the belt pulley, and drives the four groups of shifting pieces to rotate uniformly, so that the corn cobs are dispersed transversely into the peeling assembly 3. The circumferential distribution of the shifting pieces ensures continuous and uniform feeding of the corn, and avoids local accumulation. The structure of the shifting pieces avoids accumulation of the corn and improves the utilization rate of the peeling roller 402.

[0036] The throwing wheel 8 is arranged at the discharging end of the gap self-adaptive adjusting belt presser corn peeling device. Figure 4 As shown in The discharging end of the peeling assembly 3 is provided with an upper cover 406, the upper cover 406 is matched and buckled above the peeling roller 402, the two ends of the upper cover 406 are fixed on the side plate, the upper side of the throwing wheel 8 is in butt joint with the upper cover 406, the peeled corn cobs are conveyed from above the upper cover 406 to the throwing wheel 8, the end of the throwing wheel 8 is in transmission connection with the driving device, and the peeled corn cobs are conveyed out of the peeling device through the throwing wheel 8.

[0037] The throwing wheel 8 includes a horizontal shaft 801 and a throwing plate 802, the two ends of the horizontal shaft 801 are installed on the side plate through shaft seats, a plurality of throwing plates 802 are circumferentially distributed on the horizontal shaft 801 with the horizontal shaft 801 as the center, the throwing plate 802 is an integral flat plate, the throwing plate 802 is transversely arranged between the side plates, and the length of the throwing plate 802 is greater than the width of the peeling assembly 3.

[0038] The peeled corn is guided to fall into the throwing wheel 8 through the upper cover 406. The horizontal shaft 801 drives the multiple throwing plates 802 to rotate at high speed. The throwing plates 802 are used to throw the corn transversely away from the device by using the centrifugal force. The length of the throwing plates 802 covers the width of the peeling roller 402, so as to ensure that there is no residual output. The wide coverage of the throwing plates 802 realizes efficient discharging and reduces manual intervention.

[0039] As shown in Figure 3 and Figure 4 The peeling assembly 3 includes two pairs of peeling rollers 402. A cross beam 401 is fixed between the side plates. The shaft seats are arranged on the cross beam 401. The peeling rollers 402 are arranged between the side plates through the shaft seats. The gear 403 is installed at the feeding end of the peeling roller 402. The gears 403 at the ends of the adjacent peeling rollers 402 are engaged.

[0040] The power shaft 6 is also installed between the side plates. The power shaft 6 is in transmission connection with one of the peeling rollers 402 through the bevel gear set 601. The end of the power shaft 6 extends outwardly from the side plate. The belt pulley is installed on the extended end. The power shaft 6 is in transmission connection with the driving device through the belt pulley.

[0041] The swing rods 404 are also symmetrically installed at the two ends of the cross beam 401. The elastic shock rods 405 are installed between the lower ends of the swing rods 404. The shaft seats are arranged at the upper ends of the swing rods 404. The ends of the outer side peeling rollers 402 are sleeved in the shaft seats at the upper ends of the swing rods 404. Since the outer side peeling rollers 402 will swing slightly with the swing rods 404, the power shaft 6 is in meshing transmission with one of the middle two peeling rollers 402 through the bevel gear set 601.

[0042] The four peeling rollers 402 of the peeling assembly 3 are arranged in a V-shaped groove. The middle two peeling rollers 402 are arranged at a lower position. The peeling rollers 402 on the two sides are arranged at a higher position. The four peeling rollers 402 are symmetrically arranged around the middle. The four peeling rollers 402 are divided into two groups. The synchronous reverse rotation is realized through the meshing of the gears 403. The power shaft 6 drives one of the peeling rollers 402 through the bevel gear set 601. The remaining rollers are driven to rotate cooperatively. The suspension system composed of the swing rods 404 and the elastic shock rods 405 allows the outer side peeling rollers 402 to swing within a certain range, so as to adapt to the size change of the corn cobs.

[0043] When the corn cobs enter the gap between the peeling rollers 402, the larger corn will push the peeling rollers 402 outward. The swing rods 404 will swing. The elastic shock rods 405 will buffer the impact force through compression or stretching. This design makes the gap between the peeling rollers 402 self-adapt to the diameter of the corn, avoids the hard extrusion to cause the damage of the kernels, and maintains the stable peeling pressure.

[0044] As shown in Figure 5As shown, the pressure feeding assembly 4 comprises a driving shaft 302, a driven shaft 303, a tensioning shaft 304 and a belt 301, wherein the driving shaft 302 and the driven shaft 303 are respectively installed at two ends of the side plate on the upper side, the annular belt 301 is sleeved on the driving shaft 302 and the driven shaft 303, the downward extending tensioning shaft 304 is installed between the annular belt 301, and the belt 301 is pressed towards the peeling assembly 3 by the tensioning shaft 304.

[0047] As shown in Figure 3 and Figure 7 The horizontal flat hole 102 is arranged on the side plate at both ends of the driven shaft 303, the two ends of the driven shaft 303 are sleeved in the horizontal flat hole 102, the clamping groove 3031 is arranged on both sides of the horizontal flat hole 102, the horizontal sliding carrier plate 3032 is inserted in the clamping groove 3031, the shaft seat is arranged on the horizontal sliding carrier plate 3032 corresponding to the position of the horizontal flat hole 102, the two ends of the driven shaft 303 are sleeved in the shaft seat on the horizontal sliding carrier plate 3032, the longitudinal push plate 3033 longitudinally extends on the left side or the right side of the horizontal sliding carrier plate 3032, the guide rod 3034 is fixed on the longitudinal push plate 3033, the guide seat 3036 is arranged on the side plate, the guide hole is arranged on the guide seat 3036, the guide rod 3034 is sleeved in the guide hole, the spring 3035 is sleeved on the guide rod 3034 between the guide seat 3036 and the longitudinal push plate 3033, and the driven shaft 303 moves in the horizontal flat hole 102 by the expansion and contraction of the spring 3035.

[0048] As shown in Figure 6As shown, the fixed support plate 305 is installed between the side plates, the support plate 305 transversely passes through the annular belt 301, a group of vertical perforations are arranged on the support plate 305, the vertical shaft 306 is sleeved in the perforation, the lower end of the vertical shaft 306 is provided with a shaft seat, the tension shaft 304 is installed between the shaft seats, the end of the vertical shaft 306 located on the upper side of the support plate 305 is provided with a stop table, the stop table and the support plate 305 are installed with the tension spring 309, the vertical shaft 306 is pushed downward through the tension spring 309, so that the tension shaft 304 can press the inner side of the belt 301 below, the belt 301 is close to the peeling assembly 3, and flexible extrusion of the corn cob is realized. The synchronous rod 307 is further installed between the vertical shaft 306 and the support plate 305, and the two ends of the synchronous rod 307 are fixedly connected with the vertical shaft 306.

[0049] The support plate 305 on the two sides of the vertical shaft 306 is further provided with a pair of upward extending guide columns, and the stop table of the vertical shaft 306 on the upper end is a plate type spring upper cover 308, the spring upper cover 308 is provided with a positioning hole corresponding to the guide column, and the guide column is sleeved in the positioning hole. The guide column further limits the movement direction of the vertical shaft 306.

[0050] During the working process, the tension shaft 304 moves up and down due to the different sizes of the corn ears, when the tension shaft 304 moves up, the supporting force of the belt 301 is reduced, at this time, the spring 3035 pushes the longitudinal push plate 3033 to drive the driven shaft 303 to move outward, thereby compensating the contraction caused by the upward movement of the tension shaft 304, ensuring that the belt 301 is always in a tension state during operation, and avoiding the problem that the belt 301 cannot effectively rotate due to the upward movement of the tension shaft 304.

[0051] As shown in the figure, Figure 5 The outer surface of the belt 301 is uniformly provided with a series of connecting convex teeth 3011, the V-shaped pressing plate is installed on the connecting convex teeth 3011, and the V-shaped pressing plate and the V-shaped groove formed by the peeling roller 402 are matched in shape. The outer V-shaped pressing plate 3012 of the belt 301 and the V-shaped groove of the peeling roller 402 form a closed guide channel, the corn cob is continuously rubbed during the conveying process, the peeling and conveying are completed synchronously, and the efficiency is improved by more than 30%.

[0052] The working process of the present application: during operation, the power shaft 6 is connected to the driving device, power is transmitted to the gear 403 group in front of the peeling assembly 3 through the power shaft 6, and is transmitted to the distribution wheel 501 and the driving shaft 302 through the belt 301 or chain transmission.

[0053] The corn ear enters the stripping device through the feeding plate, and is uniformly distributed to the rear through the rotating distribution wheel 501. When the corn ear enters the stripping roller 402 group, the paired and oppositely rotating stripping rollers 402 generate friction on the bracts of the corn ear. When the friction between the stripping roller 402 and the bracts is greater than the connection force between the leaf sheath and the ear stalk or the connection force between the corn ear and the ear stalk, the bracts are stripped.

[0054] By setting a specific inclination angle of the stripping roller 402 and a wavy concave-convex friction pattern on the surface of the stripping roller 402, the corn ear is subjected to different friction forces and directions from the two stripping rollers 402, so that the corn ear rotates around its own axis during stripping, facilitating the layer-by-layer stripping of the bracts of the corn ear.

[0055] At the same time, the pressure feeder is driven by the driving shaft 302, so that the entire pressure belt 301 starts to rotate, and the three sets of self-adaptive adjusting devices also rotate with the driven shaft 303, and are supported and compressed by the spring. The pressure belt 301 compresses the corn ear while conveying the corn, and uses the floating characteristics of the belt pressure feeder itself to realize self-adaptive adjustment of corn ears of different diameters. When the corn reaches the self-adaptive adjusting device, the rotating tensioning shaft 304 also rises upward, appropriately reducing the damage to the ear and the loss of grain. During the lifting and lowering of the tensioning shaft 304 of the self-adaptive adjusting device, the total length of the pressure belt 301 remains unchanged, so a driven tensioning device is provided at the driven shaft 303 to tension the pressure belt, so as to avoid the loosening of the pressure belt affecting the pressure conveying effect.

[0056] The device replaces the traditional rigid pressure conveying with a mechanical self-adaptive structure, significantly reduces the corn breakage rate (which can be controlled below 2%), and the stripping rate reaches 98%. The modular design and dynamic adjustment function are suitable for large-scale agricultural processing scenes, and take into account efficient production and equipment durability, providing a new solution for corn primary processing.

[0057] In actual application, part of the corn ear and the pressure belt 301 have too large friction, which causes the stripping roller 402 to be unable to drive the corn ear to rotate, resulting in incomplete stripping of the corn ear during the stripping process.

[0058] Based on the situation, the invention further sets the protruding convex rod on the vertical shaft 306 of the installation tension shaft 304, sets the connecting rod 311 on the convex rod of the three vertical shafts 306, and the connecting rod 311 connects the three vertical shafts 306 at the same time, sets the eccentric cam 312 on the lower side of the connecting rod 311, and the eccentric cam 312 rotates by the motor drive, and the connecting rod 311 is lifted by the eccentric cam 312 gap, so that the tension shaft 304 moves intermittently, and in the moving process, the pressure of the belt 301 on the corn rod is reduced, and the corn rod is convenient to turn over with the peeling roller 402.

[0059] Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope protected by the present application.
