Description

Technical Field

[0001] The utility model relates to the technical field of harvesters, in particular to a harvester adaptable to terrain. Background Art

[0002] The boundary between urbanization and agricultural land in my country will become more obvious, and the number of large farms will gradually increase. However, in my country, there are still some places where agricultural resources are not suitable for growing conventional field crops, and in some mountainous areas, large agricultural machinery cannot be used. Therefore, the mechanization problem of these "special" areas and "niche" varieties has become one of the bottlenecks restricting the improvement of the overall mechanization level of agricultural production in my country.

[0003] In some areas, the terrain is mainly mountainous and hilly, surrounded by mountains on the east, south and west. In many places, rice cannot be planted on a large scale, and large harvesters cannot enter the site for operation. Currently, the market is almost entirely large rice threshing harvesters suitable for large tracts of flat land. Moreover, when a small harvester is harvesting, if most of the rice at the rear of the machine body is missed and not harvested, the machine body needs to be turned around and harvested again, which is very time-consuming and laborious. Moreover, for the ground with large pits, it is difficult for the current harvester to harvest the rice in the pits, which increases people's harvesting process. For this reason, we propose a small harvester suitable for multiple terrains.

[0004] In the prior art, a Chinese patent with publication number CN211702995U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a small harvester suitable for multiple terrains, including a support seat, a body, a cab, a crawler walking mechanism, a fixed seat, a rotating rod, a fixed rod, a support column and a harvesting mechanism. The corresponding two side walls of the support seat are both equipped with crawler walking mechanisms, the top of the support seat is equipped with a body, and the top of the body is rotatably connected to the fixed seat, and a cab is installed at one end of the top of the fixed seat. This small harvester can stably walk on various terrains. The invention has a wide application range and is easy to promote and use. It can harvest the fallen rice without turning the machine body around, and is relatively convenient to use. By arranging a limit block and a cutter at the bottom of the lifting plate, when encountering a larger pit on the ground, the cylinder can be controlled to make the limit block move back and forth along the lifting plate, and the cutter can move back and forth to harvest the rice in the pit. The harvest is relatively clean, reducing the harvesting process for farmers and making it more convenient to use. However, the device still has defects when used in mountainous areas, hills and other areas. It cannot achieve the ideal effect when harvesting crops planted on some slopes, and its effect is limited. Summary of the invention

[0005] The purpose of the utility model is to provide a harvester that adapts to the terrain, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A harvester that adapts to terrain includes a harvester body, a storage tank and a crawler track. A baffle is fixedly connected to one side of the harvester body, a control box and a rotating plate are respectively provided on the side of the baffle away from the harvester body, a first harvesting mechanism and a second harvesting mechanism are provided on the outer side of the rotating plate, a plurality of slide grooves are respectively provided on both sides of the rotating plate, the first harvesting mechanism and the second harvesting mechanism are slidably connected to the rotating plate through the slide grooves, a rotating component for controlling the rotation of the rotating plate is connected in the control box, a control component for controlling the sliding of the first harvesting mechanism and the second harvesting mechanism is connected in the rotating plate, a driving motor is fixedly connected to one side of the control box, a servo motor is fixedly connected to the top of the rotating plate, and a protective shell is fixedly connected to one side of the rotating plate.

[0008] When the harvester is located on uneven ground and there is a height difference between the tracks on both sides, the drive motor starts to rotate, driving the rotating parts to work, so that the first harvesting mechanism and the second harvesting mechanism at one end of the rotating plate are parallel to the ground or the tracks. At this time, the distance between the first harvesting mechanism and the second harvesting mechanism can be adjusted by controlling the control parts, thereby achieving the purpose of maximizing the grain harvesting.

[0009] A further improvement of the technical solution of the utility model is that: the control component includes a driving gear, which is rotatably connected to the rotating plate through a rotating shaft, a gear ring is arranged on the outer side of the driving gear, and the gear ring is fixedly connected to the driving gear through the rotating shaft, a driven gear is symmetrically arranged between the driving gear and the gear ring, the driven gear is rotatably connected to the rotating plate through a supporting shaft, the other end of the supporting shaft is fixedly connected to the rotating gear, a transmission worm is rotatably arranged in the rotating plate, one end of the transmission worm is fixedly connected to the output end of the servo motor, a transmission worm wheel is fixedly connected to the rotating shaft, the transmission worm wheel is meshed with the transmission worm, a plurality of racks are fixedly connected to the first harvesting mechanism and the second harvesting mechanism, the racks are meshed with the rotating gear, and half of the teeth are arranged on the driving gear and the gear ring.

[0010] The above technical solution is adopted. In this solution, when there is no height difference between the tracks on both sides, the servo motor starts and drives the transmission worm to rotate. The transmission worm drives the rotating shaft to rotate by driving the transmission worm wheel meshing with it. Because the driving gear and the ring gear are fixedly connected to the rotating shaft, the driving gear and the ring gear will rotate at the same time. Driven gears are symmetrically arranged between the driving gear and the ring gear, so the driven gear will rotate at the same time as the driving gear and the ring gear. Because the driving gear and the ring gear are both provided with half teeth, the rotation directions of the symmetrically arranged driven gears are opposite. The opposite rotation directions of the symmetrically arranged driven gears will make the rotation directions of the rotating gears opposite. At this time, the meshing relationship between the gear and the rack is used to realize the centering of the first harvesting mechanism and the second harvesting mechanism. At the same time, compared with the traditional method, such a setting can greatly improve the working stability of the device and reduce the wear of parts.

[0011] A further improvement of the technical solution of the utility model is that the rotating component includes a rotating worm, which is rotatably connected to the control box. A shaft body is rotatably provided inside the control box, a rotating worm wheel is fixedly connected to the shaft body, the rotating worm wheel is meshed with the rotating worm, and one end of the shaft body is fixedly connected to the rotating plate.

[0012] The above-mentioned technical solution is adopted. In this solution, when there is a height difference between the tracks on both sides, the motor is started at this time. The rotation of the motor will drive the rotating worm to rotate, and the rotating worm will drive the rotating worm wheel engaged with it to rotate. At this time, the rotating plate fixedly connected to the shaft will rotate until it is parallel to the ground, thereby achieving the purpose of the first harvesting mechanism and the second harvesting mechanism being parallel to the ground, thereby improving the working efficiency of the device. The rotating worm and the rotating worm wheel are arranged to cooperate with each other because they have a compact structure, a large transmission ratio and a high load-bearing capacity.

[0013] A further improvement of the technical solution of the utility model is that the directions of the teeth on the driving gear and the teeth on the gear ring are opposite.

[0014] The above technical solution is adopted, in which the teeth on the driving gear and the teeth on the ring gear are arranged in opposite directions in order to ensure that the symmetrically arranged driven gears must have a meshing connection with one of them, so as to ensure that the driven gear can reciprocate normally and prevent the same driven gear from being damaged by being connected to the driving gear and the ring gear at the same time.

[0015] A further improvement of the technical solution of the utility model is that the number of teeth of the driving gear is greater than the number of teeth of the driven gear.

[0016] By adopting the above technical solution, in which the number of teeth of the driving gear is set to be greater than the number of teeth of the driven gear, the stroke of the first harvesting mechanism and the second harvesting mechanism can be increased, thereby increasing the working range of the first harvesting mechanism and the second harvesting mechanism.

[0017] A further improvement of the technical solution of the utility model is that the number of teeth on the gear ring is equal to the number of teeth on the driving gear.

[0018] The above technical solution is adopted. In this solution, the number of teeth on the ring gear and the driving gear is set to be equal because the driving gear and the ring gear rotate unidirectionally when working, so the ring gear and the driving gear need to respectively mesh with the symmetrically arranged driven gears, thereby driving the driven gear to perform reciprocating rotation. If the number of teeth on the ring gear and the driving gear are not equal, the number of reciprocating rotations of the driven gear will be unequal, resulting in damage to the first harvesting mechanism and the second harvesting mechanism due to different reciprocating sliding strokes.

[0019] A further improvement of the technical solution of the utility model is that limiting teeth are fixedly connected to the racks.

[0020] The above technical solution is adopted, in which a limit tooth is fixedly connected to one end of the rack because when the rack and the rotating gear are engaged with each other for work, sometimes the movement overload may cause the rack to accidentally disengage, which will reduce the stability of the device. This setting can prevent the first harvesting mechanism and the second harvesting mechanism from malfunctioning during operation, thereby improving the working efficiency of the device.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model provides a harvester that adapts to terrain. The teeth on the driving gear and the teeth on the gear ring are arranged in opposite directions so that the symmetrically arranged driven gears must be in meshing connection with one of them, so that the driven gears can reciprocate normally and prevent the same driven gear from being damaged by being connected to the driving gear and the gear ring at the same time.

[0023] 2. The utility model provides a harvester that adapts to terrain. By setting the number of teeth of the driving gear to be greater than the number of teeth of the driven gear, the stroke of the first harvesting mechanism and the second harvesting mechanism can be increased, thereby increasing the working range of the first harvesting mechanism and the second harvesting mechanism.

[0024] 3. The utility model provides a harvester that adapts to terrain. The reason why the number of teeth on the ring gear and the driving gear is equal is that the driving gear and the ring gear rotate unidirectionally when working, so the ring gear and the driving gear need to respectively mesh with the symmetrically arranged driven gears, thereby driving the driven gears to perform reciprocating rotation. If the number of teeth on the ring gear and the driving gear are not equal, the number of reciprocating rotations of the driven gear will be unequal, resulting in damage to the first harvesting mechanism and the second harvesting mechanism due to different reciprocating sliding strokes.

[0025] 4. The utility model provides a harvester that adapts to the terrain. A limit tooth is fixedly connected to one end of the rack because when the rack and the rotating gear are engaged with each other for work, sometimes the movement overload may cause the rack to accidentally disengage, which will reduce the working stability of the device. This arrangement can prevent the first harvesting mechanism and the second harvesting mechanism from malfunctioning during operation, thereby improving the working efficiency of the device.

DETAILED DESCRIPTION

[0033] The present invention is further described in detail below in conjunction with the embodiments:

[0034] Example 1

[0035] like Figure 1As shown, the utility model provides a harvester that adapts to terrain, including a harvester body 1, a storage tank 2 and a crawler 3, a baffle is fixedly connected to one side of the harvester body 1, a control box 4 and a rotating plate 5 are respectively provided on the side of the baffle away from the harvester body 1, a first harvesting mechanism 6 and a second harvesting mechanism 7 are provided on the outer side of the rotating plate 5, a plurality of slide grooves 8 are respectively opened on both sides of the rotating plate 5, the first harvesting mechanism 6 and the second harvesting mechanism 7 are slidably connected to the rotating plate 5 through the slide grooves 8, a rotating component for controlling the rotation of the rotating plate 5 is connected in the control box 4, a control component for controlling the sliding of the first harvesting mechanism 6 and the second harvesting mechanism 7 is connected in the rotating plate 5, a driving motor 9 is fixedly connected to one side of the control box 4, a servo motor 10 is fixedly connected to the top of the rotating plate 5, and a protective shell 11 is fixedly connected to one side of the rotating plate 5.

[0036] In this embodiment, when the harvester is located on uneven ground and there is a height difference between the tracks 3 on both sides, the drive motor 9 starts to rotate, driving the rotating parts to work, so that the first harvesting mechanism 6 and the second harvesting mechanism 7 at one end of the rotating plate 5 are parallel to the ground or the tracks 3. At this time, the distance between the first harvesting mechanism 6 and the second harvesting mechanism 7 can be adjusted by controlling the control parts, so as to achieve the purpose of maximizing the grain harvesting.

[0037] like Figure 4 As shown, in the present embodiment, preferably, the control component includes a driving gear 12, which is rotatably connected to the rotating plate 5 through a rotating shaft 13, a ring gear 14 is provided on the outer side of the driving gear 12, and the ring gear 14 is fixedly connected to the driving gear 12 through the rotating shaft 13, a driven gear 15 is symmetrically provided between the driving gear 12 and the ring gear 14, the driven gear 15 is rotatably connected to the rotating plate 5 through a supporting shaft, a rotating gear 18 is fixedly connected to the other end of the supporting shaft, a transmission worm 17 is rotatably provided in the rotating plate 5, one end of the transmission worm 17 is fixedly connected to the output end of the servo motor 10, a transmission worm wheel 16 is fixedly provided on the rotating shaft 13, and the transmission worm wheel 16 is meshed with the transmission worm 17, a plurality of racks 19 are fixedly provided on the first harvesting mechanism 6 and the second harvesting mechanism 7, the racks 19 are meshed with the rotating gear 18, and half of the teeth are provided on the driving gear 12 and the ring gear 14.

[0038] When there is no height difference between the crawlers 3 on both sides, the servo motor 10 is started to drive the transmission worm 17 to rotate. The transmission worm 17 drives the rotating shaft 13 to rotate by driving the transmission worm wheel 16 meshing therewith. Because the driving gear 12 and the ring gear 14 are fixedly connected to the rotating shaft 13, the driving gear 12 and the ring gear 14 will rotate at the same time. A driven gear 15 is symmetrically arranged between the driving gear 12 and the ring gear 14, so the driven gear 15 will rotate at the same time as the driving gear 12 and the ring gear 14. Because the driving gear 12 and the ring gear 14 are both provided with half teeth, the rotation directions of the symmetrically arranged driven gears 15 are opposite, and the opposite rotation directions of the symmetrically arranged driven gears 15 will make the rotation directions of the rotating gear 18 opposite. At this time, the first harvesting mechanism 6 and the second harvesting mechanism 7 are aligned through the meshing relationship between the gear and the rack 19. At the same time, such an arrangement can greatly improve the working stability of the device compared with the traditional method, and can also reduce the wear of parts.

[0039] like Figure 3 As shown, preferably, the rotating component includes a rotating worm 20, which is rotatably connected to the control box 4. A shaft 22 is rotatably provided inside the control box 4, and a rotating worm wheel 21 is fixedly connected to the shaft 22. The rotating worm wheel 21 is meshed with the rotating worm 20, and one end of the shaft 22 is fixedly connected to the rotating plate 5.

[0040] When there is a height difference between the tracks 3 on both sides, the motor is started at this time. The rotation of the motor will drive the rotating worm 20 to rotate, and the rotating worm 20 will drive the rotating worm wheel 21 meshing with it to rotate. At this time, the rotating plate 5 fixedly connected to the shaft 22 will rotate until it is parallel to the ground, thereby achieving the purpose of the first harvesting mechanism 6 and the second harvesting mechanism 7 being parallel to the ground, thereby improving the working efficiency of the device. The rotating worm 20 and the rotating worm wheel 21 are arranged to cooperate with each other because they have a compact structure, a large transmission ratio and a high load-bearing capacity.

[0041] Example 2

[0042] like Figure 4 As shown, based on Example 1, the utility model provides a technical solution: preferably, the teeth on the driving gear 12 and the teeth on the ring gear 14 are in opposite directions.

[0043] In this embodiment, the teeth on the driving gear 12 and the teeth on the ring gear 14 are arranged in opposite directions so that the symmetrically arranged driven gears 15 must be in meshing connection with one of them, thereby ensuring that the driven gear 15 can reciprocate normally and preventing the same driven gear 15 from being damaged by being connected to both the driving gear 12 and the ring gear 14 at the same time.

[0044] like Figure 4As shown, preferably, the number of teeth of the driving gear 12 is greater than the number of teeth of the driven gear 15 .

[0045] By setting the number of teeth of the driving gear 12 to be greater than the number of teeth of the driven gear 15 , the stroke of the first harvesting mechanism 6 and the second harvesting mechanism 7 can be increased, thereby increasing the working range of the first harvesting mechanism 6 and the second harvesting mechanism 7 .

[0046] Example 3

[0047] like Figure 4 As shown, based on Example 2, the utility model provides a technical solution: preferably, the number of teeth on the ring gear 14 is equal to the number of teeth on the driving gear 12.

[0048] In this embodiment, the number of teeth on the ring gear 14 and the driving gear 12 is equal because the driving gear 12 and the ring gear 14 rotate unidirectionally during operation, so the ring gear 14 and the driving gear 12 need to respectively mesh with the symmetrically arranged driven gear 15, thereby driving the driven gear 15 to perform reciprocating rotation. If the number of teeth on the ring gear 14 and the driving gear 12 are not equal, the number of reciprocating rotations of the driven gear 15 will be unequal, resulting in damage to the first harvesting mechanism 6 and the second harvesting mechanism 7 due to different reciprocating sliding strokes.

[0049] Example 4

[0050] like Figure 5 As shown, based on Example 3, the utility model provides a technical solution: preferably, the rack 19 is fixedly connected with limiting teeth 23.

[0051] In this embodiment, a limit tooth 23 is fixedly connected to one end of the rack 19 because when the rack 19 and the rotating gear 18 are engaged with each other for operation, sometimes the movement overload may cause the rack 19 to accidentally disengage, which will reduce the stability of the device. This arrangement can prevent the first harvesting mechanism 6 and the second harvesting mechanism 7 from malfunctioning during operation, thereby improving the working efficiency of the device.

[0052] The following is a detailed description of the working principle of the terrain-adaptable harvester.

[0053] like Figure 1-5As shown, when the harvester is located on an uneven ground and there is a height difference between the tracks 3 on both sides, the drive motor 9 starts to rotate, driving the rotating parts to work, so that the first harvesting mechanism 6 and the second harvesting mechanism 7 at one end of the rotating plate 5 are parallel to the ground or the tracks 3. At this time, the distance between the first harvesting mechanism 6 and the second harvesting mechanism 7 can be adjusted by controlling the control parts, so as to achieve the purpose of maximizing the grain harvesting. When there is no height difference between the crawlers 3 on both sides, the servo motor 10 is started to drive the transmission worm 17 to rotate. The transmission worm 17 drives the rotating shaft 13 to rotate by driving the transmission worm wheel 16 meshing therewith. Because the driving gear 12 and the ring gear 14 are fixedly connected to the rotating shaft 13, the driving gear 12 and the ring gear 14 will rotate at the same time. A driven gear 15 is symmetrically arranged between the driving gear 12 and the ring gear 14, so the driven gear 15 will rotate at the same time as the driving gear 12 and the ring gear 14. Because the driving gear 12 and the ring gear 14 are both provided with half teeth, the rotation directions of the symmetrically arranged driven gears 15 are opposite, and the opposite rotation directions of the symmetrically arranged driven gears 15 will make the rotation directions of the rotating gear 18 opposite. At this time, the first harvesting mechanism 6 and the second harvesting mechanism 7 are aligned through the meshing relationship between the gear and the rack 19. At the same time, such an arrangement can greatly improve the working stability of the device compared with the traditional method, and can also reduce the wear of parts. When there is a height difference between the two tracks 3, the motor is started at this time, and the rotation of the motor will drive the rotating worm 20 to rotate, and the rotating worm 20 will drive the rotating worm wheel 21 meshed with it to rotate. At this time, the rotating plate 5 fixedly connected to the shaft body 22 will rotate until it is parallel to the ground, thereby achieving the purpose of the first harvesting mechanism 6 and the second harvesting mechanism 7 being parallel to the ground, thereby improving the working efficiency of the device. The rotating worm 20 and the rotating worm wheel 21 are arranged to cooperate with each other because they have a compact structure, a large transmission ratio and a high load-bearing capacity. The teeth on the driving gear 12 are arranged in opposite directions to the teeth on the ring gear 14 so that the symmetrically arranged driven gear 15 must have a meshing connection relationship with one of them, so that the driven gear 15 can be ensured to reciprocate normally, and the same driven gear 15 is prevented from being damaged by being connected to the driving gear 12 and the ring gear 14 at the same time. Setting the number of teeth of the driving gear 12 to be greater than the number of teeth of the driven gear 15 can increase the stroke of the first harvesting mechanism 6 and the second harvesting mechanism 7, thereby increasing the working range of the first harvesting mechanism 6 and the second harvesting mechanism 7.The reason why the number of teeth on the ring gear 14 and the driving gear 12 is equal is that the driving gear 12 and the ring gear 14 rotate in one direction when working, so the ring gear 14 and the driving gear 12 need to mesh with the symmetrically arranged driven gear 15 respectively, so as to drive the driven gear 15 to perform reciprocating rotation. If the number of teeth on the ring gear 14 and the driving gear 12 are not equal, the number of reciprocating rotations of the driven gear 15 will be unequal, resulting in damage to the first harvesting mechanism 6 and the second harvesting mechanism 7 due to different reciprocating sliding strokes. The reason why the limited position teeth 23 are fixedly connected at one end of the rack 19 is that when the rack 19 and the rotating gear 18 mesh with each other for work, sometimes the overload of movement will cause the rack 19 to accidentally disengage, which will reduce the stability of the device. Such a setting can prevent the first harvesting mechanism 6 and the second harvesting mechanism 7 from malfunctioning during work, thereby improving the working efficiency of the device.

[0054] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
