Description

Technical Field

[0001] This utility model relates to the field of corn harvesters, specifically to a quick-repair structure for a peeling machine and a corn harvester. Background Technology

[0002] As a key component of corn harvesters, the performance of the hulling machine directly affects the overall harvesting efficiency, husk removal rate, and kernel loss rate. Currently, the mainstream hulling machine configuration is fixed, with a fixed position within the machine that cannot be moved. Because the hulling machine is located in the center of the machine, the space in front is limited, making it inaccessible for personnel to perform maintenance. Repairing the hulling machine requires complete disassembly, consuming significant manpower and resources.

[0003] To ensure ease of maintenance of the peeling machine and reduce maintenance time, the installation structure of the peeling machine needs to be improved. Utility Model Content

[0004] The technical problem to be solved by this utility model is how to facilitate the maintenance of peeling machines.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a quick repair structure for a peeling machine, including a peeling machine, a frame and a guide wheel assembly, wherein the peeling machine and the frame are detachably connected, the guide wheel assembly is installed on the frame and slides with the bottom of the peeling machine.

[0006] The beneficial effects of this invention are: after disconnecting the peeling machine from the frame, the peeling machine can be pushed backward under the guidance of the guide wheel assembly, thus creating space in front for maintenance and adjustment of the front rocker arm tension spring. This saves time in disassembling the peeling machine, improves maintenance efficiency, and enhances product competitiveness and user satisfaction.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the guide wheel assembly includes at least one swing arm and a connecting rod. The middle part of the swing arm is hinged to the frame via a swing arm pin. A guide wheel is rotatably mounted on one end of the swing arm, and the other end of the swing arm is hinged to the connecting rod. The guide wheel is in sliding engagement with the bottom of the peeling machine.

[0009] The beneficial effects of adopting the above-mentioned further solution are: by synchronously driving the other end of at least one swing arm through the connecting rod, the swing arm uses the lever principle to lift the peeling machine through the guide wheel, so that the peeling machine is separated from the frame, thereby allowing the peeling machine to slide on the guide wheel under the action of external force, realizing the independent movement of the peeling machine with low movement resistance.

[0010] Furthermore, the guide wheel assembly also includes a pull rod and a limiting nut. One end of the pull rod is hinged to the connecting rod or the other end of one of the swing arms. A limiting plate is fixed on the frame. The other end of the pull rod passes through the limiting plate. The limiting nut is provided on at least one side of the limiting plate. The limiting nut is threadedly connected to the pull rod.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the limiting nut, in conjunction with the limiting plate, achieves axial limiting of the pull rod. When it is necessary to lift the peeling machine, pull the pull rod to lift the peeling machine, and finally tighten the limiting nut to prevent the peeling machine from falling, allowing the peeling machine to move laterally. After maintenance, push the peeling machine back to its original position, loosen the limiting nut, and the weight of the peeling machine will push the swing arm to rotate back to its original position. Then tighten the limiting nut again to limit the pull rod.

[0012] Furthermore, the distance from the axis of the swing arm pin to the bottom of the peeling machine is less than the distance from the axis of the swing arm pin to the upper end of the corresponding guide wheel.

[0013] The beneficial effect of adopting the above-mentioned further solution is that when the swing arm swings, the peeling machine can be lifted up by utilizing the difference between the length of one end of the swing arm and the distance from the axis of the swing arm pin to the bottom of the peeling machine.

[0014] Furthermore, the other end of the pull rod is threadedly connected to a limiting nut, which abuts against one side of the limiting plate, and there is a movable gap between the other side of the limiting plate and one end of the pull rod.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, under the action of gravity of the peeling machine, the limiting nut always abuts against one side of the limiting plate, so only one limiting nut needs to be set, which is simple in structure and convenient to use.

[0016] Furthermore, the bottom sidewall of the peeling machine has a groove extending in the front-to-back direction, and the guide wheel is located in the groove.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the peeling machine and the guide wheel are guided by a sliding groove, ensuring a stable and smooth sliding process.

[0018] Furthermore, the guide wheel assembly includes two swing arms spaced apart front to back; the included angle between the two ends of the swing arms is an obtuse angle.

[0019] Furthermore, the guide wheel assembly is provided in two sets, and the two sets of guide wheel assemblies are respectively installed on the left and right sides of the frame.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the peeling machine is supported from both the left and right sides, resulting in a balanced force.

[0021] Furthermore, a positioning plate is fixed to the front end of the frame, and the front end of the peeling machine abuts against or separates from the positioning plate.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the positioning plate is used to determine the position of the front end of the peeling machine, which facilitates resetting after maintenance.

[0023] This utility model also provides a corn harvester, including the aforementioned quick-repair structure for the peeling machine. Attached Figure Description

[0025] The attached diagram lists the components represented by each number as follows: 1. Peeling machine; 2. Frame; 3. Swing arm; 4. Connecting rod; 5. Guide wheel; 6. Pull rod; 7. Limit nut; 8. Limit plate; 9. Swing arm pin; 10. Rocker arm tension spring; 11. Washer; 12. Channel steel. Detailed Implementation

[0026] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0027] Example 1 like Figures 1-8 As shown, this embodiment provides a quick repair structure for a peeling machine, including a peeling machine 1, a frame 2, and a guide wheel assembly. The peeling machine 1 and the frame 2 are detachably connected. The guide wheel assembly is installed on the frame 2 and slides with the bottom of the peeling machine 1.

[0028] After disconnecting the peeling machine 1 from the frame 2, the peeling machine 1 can be pushed backward under the guidance of the guide wheel assembly, thus creating space in front for maintenance and adjustment of the front rocker arm tension spring 10. This saves time in disassembling the peeling machine 1, improves maintenance efficiency, and enhances product competitiveness and user satisfaction.

[0029] Specifically, the peeling machine 1 and the frame 2 are detachably connected by multiple sets of bolt assemblies. The bolt assemblies include bolts passing through the peeling machine 1 and the frame 2, washers 11 fitted onto the bolts, and nuts threaded into the bolts. For example... Figure 3 and Figure 6 As shown, when the peeling machine 1 is working normally, the washer 11 is installed between the nut and the peeling machine 1 and is locked by the nut. When it is necessary to move the peeling machine 1, all bolt assemblies are removed; or, a portion of the bolt assemblies are removed, leaving a portion. For the remaining portion of the bolt assemblies, only the washer 11 is removed, and the nut is loosened. The bolt thread slides into the slot (opened in the front-back direction) on the peeling machine 1, so that the bolt can guide the peeling machine 1 to move back and forth, and the nut can limit the peeling machine 1 to move upward.

[0030] In one specific example, such as Figure 7 As shown, the peeling machine 1 can move 500mm along the guide wheel assembly to the rear of the machine, leaving enough space at the front for maintenance operations.

[0031] One embodiment of the guide wheel assembly is as follows: a linear drive mechanism is mounted on the frame 2, and the guide wheel 5 is rotatably mounted on the upward-facing telescopic end of the linear drive mechanism. The peeling machine 1 is lifted and lowered by the extension and retraction of the linear drive mechanism. The linear drive mechanism can be a hydraulic cylinder, a pneumatic cylinder, or an electric telescopic rod, etc.

[0032] Another implementation of the guide wheel assembly is as follows: Figure 1 and Figure 2 As shown, the guide wheel assembly includes at least one swing arm 3 and a connecting rod 4. The middle part of the swing arm 3 is hinged to the frame 2 through a swing arm pin 9. A guide wheel 5 is rotatably mounted on one end of the swing arm 3, and the other end of the swing arm 3 is hinged to the connecting rod 4. The guide wheel 5 is slidably engaged with the bottom of the peeling machine 1.

[0033] The connecting rod 4 synchronously drives the other end of at least one swing arm 3. The swing arm 3 uses the lever principle to lift the peeling machine 1 through the guide wheel 5, so that the peeling machine 1 is separated from the frame 2. This allows the peeling machine 1 to slide on the guide wheel 5 under the action of external force, realizing the independent movement of the peeling machine 1 with low movement resistance.

[0034] When there are multiple swing arms 3, the multiple swing arms 3 are parallel to each other.

[0035] The lengths of the swing arms 3 on the upper and lower sides of the swing arm pin 9 may be equal or unequal. In order to save the driving force acting on the swing arms 3, the length of the swing arm 3 on the lower side of the swing arm pin 9 is greater than the length of the swing arm 3 on the upper side of the swing arm pin 9.

[0036] Specifically, the peeling machine 1 is pushed manually. Of course, a hydraulic cylinder or other drive mechanism can also be set up to move the peeling machine.

[0037] Based on the above technical solution, the guide wheel assembly also includes a pull rod 6 and a limiting nut 7. One end of the pull rod 6 is hinged to the other end of the connecting rod 4 or one of the swing arms 3. A limiting plate 8 is fixed on the frame 2. The other end of the pull rod 6 passes through the limiting plate 8. The limiting nut 7 is provided on at least one side of the limiting plate 8. The limiting nut 7 is threadedly connected to the pull rod 6.

[0038] The limiting nut 7, in conjunction with the limiting plate 8, axially limits the pull rod 6. When it is necessary to lift the peeling machine 1, pull the pull rod 6 to lift the peeling machine 1, and finally tighten the limiting nut 7 to prevent the peeling machine 1 from falling, allowing the peeling machine 1 to move laterally. After maintenance, push the peeling machine 1 back to its original position, loosen the limiting nut 7, and the gravity of the peeling machine 1 will push the swing arm 3 to rotate back to its original position. Then tighten the limiting nut 7 again to limit the pull rod 6.

[0039] Based on the above technical solution, the distance from the axis of the swing arm pin 9 to the bottom of the peeling machine 1 is less than the distance from the axis of the swing arm pin 9 to the upper end of the corresponding guide wheel 5.

[0040] When the swing arm 3 swings, the peeling machine 1 can be lifted up by using the difference between the length of one end of the swing arm 3 and the distance from the axis of the swing arm pin 9 to the bottom of the peeling machine 1.

[0041] Based on the above technical solution, a limiting nut 7 is threadedly connected to the other end of the pull rod 6. The limiting nut 7 abuts against one side of the limiting plate 8, and there is an movable gap between the other side of the limiting plate 8 and one end of the pull rod 6.

[0042] Under the gravity of the peeling machine 1, the limiting nut 7 always abuts against one side of the limiting plate 8, so only one limiting nut 7 needs to be set, which is simple in structure and easy to use.

[0043] Specifically, such as Figure 2As shown, under the gravity of the peeling machine 1, the guide wheel 5 rotates to the rear side of the swing arm pin 9. At this time, the connecting rod 4 tends to move to the left. The limiting plate 8 and the pull rod 6 are installed at the rear end of the connecting rod 4, and the limiting nut 7 abuts against the rear side of the limiting plate 8. When it is necessary to lift the peeling machine 1, rotate the limiting nut 7 to move it to the left relative to the pull rod 6, thereby pulling the pull rod 6 to swing to the right relative to the frame 2, and driving the swing arm 3 to rotate counterclockwise. The guide wheel 5 at the upper end of the swing arm 3 lifts the peeling machine 1. When lowering the peeling machine 1, simply rotate the limiting nut 7 in the opposite direction to move it to the right relative to the pull rod 6.

[0044] Based on the above technical solution, the bottom side wall of the peeling machine 1 has a sliding groove extending in the front-back direction, and the guide wheel 5 is located in the sliding groove.

[0045] The peeling machine 1 and the guide wheel 5 are guided by a groove to ensure a stable and smooth sliding process.

[0046] Specifically, such as Figure 5 and Figure 8 As shown, a channel steel 12 is fixed to the bottom of the peeling machine 1. The channel steel 12 has a groove extending in the front-to-back direction, which forms the aforementioned sliding groove. More specifically, a channel steel 12 is provided on each of the left and right sides of the peeling machine 1, and the sliding groove is provided on the opposite side of the two channel steels 12. The guide wheel 5 is a special pulley for channel steel.

[0047] Based on the above technical solution, the guide wheel assembly includes two swing arms 3 arranged at a distance from each other; the included angle between the two ends of the swing arms 3 is an obtuse angle.

[0048] In one specific example, the connecting rod 4 has U-shaped connecting forks at both ends, and the two connecting forks are respectively hinged to the lower ends of the two swing arms 3. The corresponding swing arms 3 are inserted into the U-shaped connecting forks and connected by pins.

[0049] Based on the above technical solution, the guide wheel assembly is provided in two sets, and the two sets of guide wheel assemblies are respectively installed on the left and right sides of the frame 2.

[0050] The peeling machine 1 is supported from both the left and right sides, and the force is balanced.

[0051] Based on the above technical solution, a positioning plate is fixed at the front end of the frame 2, and the front end of the peeling machine 1 abuts against or separates from the positioning plate.

[0052] The positioning plate is used to determine the position of the front end of the peeling machine 1, which facilitates resetting after maintenance.
