Description

Technical Field

[0001] The invention relates to the technical field of corn peeling, in particular to a corn peeling device of a belt-type press conveyor with adaptive gap adjustment. Background Art

[0002] In my country, corn is generally harvested by harvesting ears. The peeling device is a key device of the corn ear combine harvester. After the corn ears are picked, the corn ear husks need to be peeled off by the peeling device. The peeling device has an important impact on the quality of corn harvest. At the same time, the harvesting of fresh corn and seed corn also adopts the ear harvesting method. The integrity of corn kernels is required to be high during harvesting. The peeling process is the core of harvesting and is the key to affecting the harvesting quality of fresh corn and seed corn.

[0003] The corn cob peeling device is mainly composed of a pressure feeder and a peeling roller group. The friction and mechanical action between the peeling roller surface and the corn cob are generated to effectively grab and peel off the husk of the corn cob. When the corn cob is grabbed by the peeling roller, the corn cob is prone to curling up, which will cause the end of the corn cob to be bitten; after the husk of the corn cob is peeled off, the bare corn cob needs to be quickly separated from the peeling device to avoid the loss of corn kernels caused by long-term contact with the peeling roller; in order to generate sufficient friction between the corn cob and the peeling roller, a pressure feeder is also required to be installed above the peeling roller, which can provide sufficient pressing force to the corn cob and prevent the corn cob from curling up while transporting the corn cob to the discharge port on the peeling roller.

[0004] Existing presses generally adopt the form of star wheels and impellers. The gap between them and the peeling roller group is relatively fixed during operation, and the gap cannot be adjusted in real time. The pressing force will be too large or insufficient due to the corn ear diameter being too large or too small, resulting in a decrease in the corn peeling rate and an increase in the loss rate and damage rate.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below.

[0022] Example 1: Figure 1-3 The corn peeling device of a belt-type press-feeder with adaptive gap adjustment shown in the figure comprises a set of side plates, a peeling assembly 3 and a press-feed assembly 4. The peeling assembly 3 and the press-feed assembly 4 are installed between the side plates, and the press-feed assembly 4 is located above the peeling assembly 3.

[0023] The side plate includes an upper side plate 1 and a lower side plate 2, and the upper and lower edges of the upper side plate 1 and the lower side plate 2 are provided with horizontal bends 104, and 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 by the bolts, wherein the peeling assembly 3 is installed between the lower side plates 2, the pressure feeding assembly 4 is installed between the upper side plates 1, the feed port 5 is fixed at the end of the upper side plate 1, and the throwing wheel 8 is installed between the lower side plates 2.

[0024] The upper side plate 1 is also provided with an inspection port, on which an inspection window 7 is installed. 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, so as to facilitate the maintenance of the peeling device.

[0025] The peeling assembly 3 is fixed to the lower side plate 2 by bolts, and the transmission device, feed port 5 and distribution wheel 501 are installed in front of the peeling assembly 3, and the throwing wheel 8 is installed in the rear. The pressure conveying assembly 4 adopts a belt pressure conveyor, which is installed and fixed on the upper side plate 1, so that the belt pressure conveyor is located above the peeling roller 402 group.

[0026] The feeding end of the gap adaptively adjusted belt press feeder 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 a distribution wheel 501 is transversely arranged in the feeding port 5, and the distribution wheel 501 is located between the feeding plate and the belt press feeder. During operation, corn ears enter the peeling device through the feeding plate, pass through the rotating distribution wheel 501, and evenly enter the rear.

[0027] like Fig. 9As shown, the distribution wheel 501 includes a main shaft 5011, on which a plurality of groups of material-diverting plates 5012 are fixed, each group of material-diverting plates 5012 includes four paddles, which are evenly fixed on the main shaft 5011 with the main shaft 5011 as the center of the circle, and the two ends of the main shaft 5011 extend outward from the side plates, and a pulley is installed on the extension section of the main shaft 5011, and the pulley of the main shaft 5011 is connected to the pulley at the end of the power shaft 6 by transmission. The main shaft 5011 is linked with the power shaft 6 through the pulley, driving the four groups of paddles to rotate evenly, and distributing the corn cobs laterally into the peeling assembly 3. The circumferential distribution of the paddles ensures continuous and even feeding of corn, and avoids local accumulation. The paddle structure avoids corn accumulation and improves the utilization rate of the peeling roller 402.

[0028] A throwing wheel 8 is provided at the discharge end of the gap adaptively adjusted belt press corn peeling device. Figure 4 As shown, the discharging end of the peeling component 3 is provided with an upper cover 406, and the upper cover 406 is matched and buckled above the peeling roller 402, and the two ends of the upper cover 406 are fixed on the side plates, and the upper side of the throwing wheel 8 is connected to the upper cover 406. The peeled corn cobs are transported from above the upper cover 406 to the throwing wheel 8, and the end of the throwing wheel 8 is connected to the driving device, and the peeled corn cobs are transported out of the peeling device through the throwing wheel 8.

[0029] The throwing wheel 8 includes a transverse axis 801 and a throwing plate 802. Both ends of the transverse axis 801 are installed on the side plates through shaft seats. With the transverse axis 801 as the center, multiple throwing plates 802 are distributed on the circumference of the transverse axis 801. The throwing plate 802 is a whole flat plate, which is horizontally placed between the side plates. The length of the throwing plate 802 is greater than the width of the peeling component 3.

[0030] The peeled corn is guided by the upper cover 406 and falls into the throwing wheel 8. The horizontal shaft 801 drives the multiple throwing plates 802 to rotate at high speed, and uses centrifugal force to throw the corn horizontally away from the device. The length of the throwing plate 802 covers the width of the peeling roller 402 to ensure no residual output. The large coverage of the throwing plate 802 realizes efficient discharge and reduces manual intervention.

[0031] like Figure 3 and Figure 4 As shown, the peeling assembly 3 includes two pairs of peeling rollers 402, a crossbeam 401 is fixed between the side plates, an axle seat is provided on the crossbeam 401, the peeling rollers 402 are mounted between the side plates through the axle seat, a gear 403 is installed at the feed end of the peeling rollers 402, and the gears 403 at the ends of adjacent peeling rollers 402 are meshed.

[0032] A power shaft 6 is also installed between the side plates, and the power shaft 6 is connected to one of the peeling rollers 402 through a bevel gear set 601. The end of the power shaft 6 extends outside the side plate, and a pulley is installed on the extended end. The power shaft 6 is connected to the driving device through the pulley.

[0033] The two ends of the crossbeam 401 are symmetrically mounted with swing rods 404, between the lower ends of the swing rods 404, elastic damping rods 405 are mounted, the upper end of the swing rods 404 is provided with an axle seat, and the end of the outer peeling roller 402 is sleeved in the axle seat at the upper end of the swing rod 404. Since the outer peeling roller 402 will swing in a small range with the swing rod 404, the power shaft 6 is meshed with one of the two middle peeling rollers 402 through the bevel gear set 601 for transmission.

[0034] The four peeling rollers 402 of the peeling assembly 3 are arranged in a V-shaped groove, with the two middle peeling rollers 402 at a lower position and the peeling rollers 402 on both sides installed at a higher position. The four peeling rollers 402 are symmetrical in the middle and are divided into two groups, which are meshed with gears 403 to achieve synchronous reverse rotation. The power shaft 6 drives one of the peeling rollers 402 through the bevel gear set 601, driving the remaining rollers to rotate in coordination. The suspension system composed of the swing rod 404 and the elastic shock-absorbing rod 405 allows the outer peeling rollers 402 to swing within a certain range to adapt to the size changes of the corn cob.

[0035] When the corn cob enters the gap of the peeling roller 402, the larger corn will push the peeling roller 402 outward, and the swing rod 404 will swing accordingly, and the elastic shock-absorbing rod 405 will buffer the impact force by compression or extension. This design makes the gap of the peeling roller 402 adaptive to the diameter of the corn, avoiding hard squeezing and causing kernel damage, while maintaining a stable peeling pressure.

[0036] like Figure 5 As shown, the pressing assembly 4 includes 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 both ends of the upper side of the side plate, an annular belt 301 is mounted on the driving shaft 302 and the driven shaft 303, and a downwardly extending tensioning shaft 304 is installed between the annular belts 301, and the belt 301 is pressed by the tensioning shaft 304 to make the belt 301 approach the peeling assembly 3.

[0037] The end of the driving shaft 302 extends outward from the side plate, and a pulley is installed at the extended end, through which the driving shaft 302 is connected to the pulley on the power shaft 6.

[0038] Vertical flat holes 101 are set on the side plates at both ends of the driving shaft 302, and the two ends of the driving shaft 302 are inserted into the vertical flat holes 101. A lifting plate 3021 is set on the outer side of the side plate, and an axle seat is set on the lifting plate 3021. The two ends of the driving shaft 302 are inserted into the axle seats of the lifting plate 3021. A horizontal hanging plate 3022 is horizontally extended on the upper side of the lifting plate 3021. The horizontal hanging plate 3022 is provided with a through hole, and a hanging rod 103 is inserted into the through hole. The upper end of the hanging rod 103 is fixed on the side plate, and the lower end of the hanging rod 103 is provided with an external thread. Nuts are set on the hanging rod 103 on the upper and lower sides of the horizontal hanging plate 3022, and the horizontal hanging plate 3022 is clamped and fixed by the upper and lower nuts, so that the position of the lifting plate 3021 is fixed.

[0039] like Figure 3 and Figure 7 As shown, the side plates at both ends of the driven shaft 303 are provided with transverse flat holes 102, and the two ends of the driven shaft 303 are inserted into the transverse flat holes 102. The two sides of the transverse flat holes 102 are provided with card slots 3031, and the transverse carrier plate 3032 is inserted into the card slots 3031. The transverse carrier plate 3032 is provided with an axle seat at the position corresponding to the transverse flat hole 102. The two ends of the driven shaft 303 are sleeved in the axle seats on the transverse carrier plate 3032. The left side or the left side of the transverse carrier plate 3032 A longitudinal push plate 3033 is longitudinally extended on the right side, a guide rod 3034 is fixed on the longitudinal push plate 3033, a guide seat 3036 is arranged on the side plate, a guide hole is arranged on the guide seat 3036, the guide rod 3034 is inserted into the guide hole, a 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 is moved in the transverse flat hole 102 by the expansion and contraction of the spring 3035.

[0040] like Figure 6 As shown, a fixed support plate 305 is installed between the side plates, and the support plate 305 passes through the annular belt 301 horizontally. A group of vertical perforations are provided on the support plate 305, and a vertical shaft 306 is sleeved in the perforations. A shaft seat is provided at the lower end of the vertical shaft 306, and a tension shaft 304 is installed between the shaft seats. A stopper is provided at the end of the vertical shaft 306 located on the upper side of the support plate 305, and a tension spring 309 is installed between the stopper and the support plate 305. The vertical shaft 306 is pushed downward by the tension spring 309, so that the tension shaft 304 can press the inner side of the belt 301 below, so that the belt 301 is close to the peeling assembly 3, and the corn cob is flexibly squeezed. A synchronization rod 307 is also installed between the vertical shafts 306, and the synchronization rod 307 is located between the support plate 305 and the tension shaft 304, and the two ends of the synchronization rod 307 are fixedly connected to the vertical shaft 306.

[0041] A pair of upwardly extending guide columns are also provided on the support plates 305 on both sides of the vertical axis 306. The stopper at the upper end of the vertical axis 306 is a plate-type spring upper cover 308. The spring upper cover 308 is provided with positioning holes corresponding to the guide columns. The guide columns are inserted into the positioning holes, and the moving direction of the vertical axis 306 is further limited by the guide columns.

[0042] During operation, the tensioning shaft 304 moves up and down due to the different sizes of corn ears. When the tensioning shaft 304 moves upward, its supporting force on 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 for the contraction caused by the upward movement of the tensioning shaft 304, ensuring that the belt 301 always remains in a tensioned state during operation, avoiding the problem of the belt 301 becoming loose and unable to rotate effectively due to the upward movement of the tensioning shaft 304.

[0043] like Figure 5 As shown, the outer surface of the belt 301 is evenly provided with a series of connecting convex teeth 3011, and a V-shaped pressure plate is installed on the connecting convex teeth 3011, and the V-shaped pressure plate matches the V-shaped groove formed by the peeling roller 402. The external V-shaped pressure plate 3012 of the belt 301 and the V-shaped groove of the peeling roller 402 form a closed guide channel, and the corn cobs are continuously kneaded during the conveying process, and the peeling and conveying are completed synchronously, and the efficiency is improved by more than 30%.

[0044] The working process of the present invention is as follows: during operation, the power shaft 6 is connected to the driving device, and the power is transmitted by the power shaft 6 to the gear 403 group in front of the peeling component 3, and is transmitted to the distribution wheel 501 and the driving shaft 302 through the belt 301 or chain drive. The driving shaft 302 has the same rotation direction as the distribution wheel 501.

[0045] Corn ears enter the peeling device through the feeding plate, and evenly enter the rear through the rotating distribution wheel 501. When the corn ears enter the peeling roller 402 group, the paired peeling rollers 402 rotating in opposite directions will generate friction on the husks of the corn ears. When the friction between the peeling rollers 402 and the husks is greater than the coupling force between the leaf sheath and the ear stalk or the coupling force between the corn ears and the ear stalk, the husks are peeled off.

[0046] By setting a specific inclination angle of the peeling roller 402 and the wavy concave-convex friction pattern on the surface of the peeling roller 402, the friction forces exerted on the corn cobs by the two peeling rollers 402 are different in magnitude and direction. Therefore, the corn cobs will rotate around their own axis when peeling, which facilitates the layer-by-layer peeling of the corn cob bracts.

[0047] At the same time, driven by the driving shaft 302, the entire conveying belt 301 will start to rotate, and the tensioning shafts 304 and driven shafts 303 of the three sets of adaptive adjustment devices will also rotate accordingly, and the conveying belt 301 will be supported and compressed under the action of the spring. The conveying belt 301 conveys corn while applying compression force to the corn cobs, and uses the floating characteristics of the belt conveyor itself to achieve adaptive adjustment of corn cobs of different diameters. When the corn reaches the adaptive adjustment device, the rotating tensioning shaft 304 will also lift upward to appropriately reduce the loss of cobs and grains. During the lifting or lowering of the tensioning shaft 304 of the adaptive adjustment device, the total length of the conveying belt 301 remains unchanged, so a driven tensioning device is provided at the driven shaft 303 to tension the conveying belt to prevent the loosening of the conveying belt from affecting the conveying effect.

[0048] The device replaces the traditional rigid pressure delivery with a mechanical adaptive structure, significantly reducing the corn breakage rate (can be controlled below 2%), while the peeling rate reaches 98%. Its modular design and dynamic adjustment function are suitable for large-scale agricultural processing scenarios, taking into account both efficient production and equipment durability, and providing a new solution for corn primary processing.

[0049] Embodiment 2: The belt 301 itself has strong elasticity. In actual application, the friction between some corn ears and the belt 301 is too large, resulting in that the peeling roller 402 cannot drive the corn ears to rotate, causing incomplete peeling of the corn ears during the peeling process.

[0050] Based on this situation, the present invention further provides a laterally extending protruding rod on the vertical shaft 306 on which the tensioning shaft 304 is installed, and a connecting rod 311 is installed on the protruding rods of the three vertical shafts 306. The connecting rod 311 simultaneously connects the three vertical shafts 306, and an eccentric cam 312 is installed on the lower side of the connecting rod 311. The eccentric cam 312 is driven to rotate by a motor, and the connecting rod 311 is intermittently lifted by the eccentric cam 312, so that the tensioning shaft 304 is intermittently moved up. During the upward movement, the pressure of the belt 301 on the corn cob is reduced, so that the corn cob is convenient to flip over with the peeling roller 402.

[0051] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
