Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, specifically to a harvester adaptable to various terrains. Background Technology
[0002] Harvesters are essential machines in modern agriculture for harvesting crops. Existing harvesters typically consist of a frame, harvesting mechanism, conveyor system, and hopper. During operation, especially on uneven terrain such as hills and mountains, the traditional harvester's frame structure struggles to adapt to the undulating ground, resulting in poor machine stability, affecting harvesting efficiency, and even posing a risk of tipping over. Furthermore, when the machine is tilted, material tends to accumulate on one side of the hopper, affecting loading capacity and potentially causing unloading difficulties. Therefore, there is an urgent need for a harvester that can better adapt to complex terrain, maintain operational stability, and ensure even material distribution.
[0003] Existing harvesters are difficult to adapt to various complex terrains, and the stability of material storage in the hopper is poor. This solution addresses this technical problem. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a harvester adaptable to various terrains. By setting up a movable front frame, a rear frame, and an automatic leveling system for the hopper, the harvester can maintain stability on complex terrains while ensuring that the hopper is basically level and the material is evenly distributed, thus improving operational safety and efficiency. The tilt angle of the hopper can be adaptive or actively adjusted by an electric cylinder for unloading operations. The harvester has strong adaptability to different terrains.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a harvester adaptable to various terrains, including a front frame, a conveyor belt inclinedly arranged on the front frame, and a harvester head arranged on the front frame. The harvester head is connected to one end of the conveyor belt. The harvester head also includes a rear frame movably connected to the front frame. A hopper is arranged on the rear frame. The other end of the conveyor belt is arranged towards the hopper. A front drive wheel is arranged on the bottom side of the front frame, and a rear drive wheel is arranged on the bottom side of the rear frame.
[0006] The rear frame is equipped with a support platform, and support plates are vertically installed on the left and right sides of the support platform. Both support plates have through arc-shaped holes. Several guide wheels are installed on both sides of the bottom of the hopper, and the guide wheels are rolled in the arc-shaped holes.
[0007] One end of each of the two support plates is hinged to the support platform, and an electric cylinder is hinged to the top side of the support platform. The telescopic end of the electric cylinder is hinged to the other end of the support plate.
[0008] The hopper is provided with a front limiting plate and a rear limiting plate on its front and rear sides, respectively. Both the front and rear limiting plates are provided with flexible buffer plates, and the front and rear sides of the hopper are in separable contact with the flexible buffer plates.
[0009] A rear box plate is hinged to the top rear side of the hopper, and a pin for locking the rear box plate is provided on the side of the hopper. The rear box plate and the pin are detachably connected.
[0010] A front crossbeam is fixedly mounted on the bottom side of the front frame, and a rear crossbeam is rotatably mounted on the rear frame. A longitudinal beam is provided between the front crossbeam and the rear crossbeam, with one end of the longitudinal beam hinged to the front crossbeam and the other end of the longitudinal beam hinged to the rear crossbeam.
[0011] Both the front drive wheel and the rear drive wheel are tracked drive wheels.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] (1) By setting up the automatic leveling of the front frame, rear frame and hopper with active connection, the harvester can maintain the stability of the machine body on complex terrain, while ensuring that the hopper is basically level and the material is evenly distributed, thus improving the safety and efficiency of operation. The tilt angle of the hopper can be adaptive or actively adjusted by electric cylinder, and then unloading operation can be carried out. The harvester has strong adaptability to different terrains.
[0014] (2) The front frame and the rear frame are connected by multiple hinge points and are equipped with tracked drive wheels, which gives the whole machine excellent contouring ability and passability. It can effectively cope with harvesting operations on irregular plots such as hills and mountains, and further improves the adaptability to different terrains. Attached Figure Description

[0023] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.
[0024] See Figures 1-7 A harvester adaptable to various terrains includes a front frame 1, a conveyor belt 2 inclinedly mounted on the front frame 1, a harvester head 3 mounted on the front frame 1, the harvester head 3 being connected to one end of the conveyor belt 2, and a rear frame 4 movably connected to the front frame 1. A hopper 5 is mounted on the rear frame 4, and the other end of the conveyor belt 2 is positioned toward the hopper 5. A front drive wheel 6 is mounted on the bottom side of the front frame 1, and a rear drive wheel 7 is mounted on the bottom side of the rear frame 4.
[0025] Specifically, a rear crossbeam 41 is rotatably mounted on the rear frame 4 (e.g., via a bearing housing), and the two ends of the longitudinal beam 12 are hinged to the front crossbeam 11 and the rear crossbeam 41 respectively via hinges (or hinge seats). This allows relative pitching and torsional movements between the front frame 1 and the rear frame 4, enabling the vehicle to better conform to uneven terrain. Track wheels, serving as rear drive wheels 7, are also mounted on the underside of the rear frame 4.
[0026] The rear frame 4 is equipped with a support platform 8, and support plates 81 are vertically arranged on the left and right sides of the support platform 8. Both support plates 81 are provided with arc-shaped holes 811. Several guide wheels 51 are provided on both sides of the bottom of the hopper 5. The guide wheels 51 are rolled in the arc-shaped holes 811.
[0027] Two support plates 81 are hinged at one end to a support platform 8, and an electric cylinder 82 is hinged on the top side of the support platform 8. The telescopic end of the electric cylinder 82 is hinged to the other end of the support plate 81.
[0028] Specifically, one end of each of the two support plates 81 is connected to the support platform 8 via a hinge, allowing the support plates 81 to swing around the hinge point. An electric cylinder 82 is also hinged to the top surface of the support platform 8, with the end of its extension rod hinged to the other end of the support plate 81. Therefore, by controlling the extension and retraction of the electric cylinder 82, the two support plates 81 can be driven to tilt forward or backward synchronously at a certain angle. The operator can actively change the angle of the support plates 81 by controlling the electric cylinder 82, thereby adjusting the tilt angle of the hopper 5, for example, tilting it backward during unloading.
[0029] When the support plate 81 is upright, the hopper 5 is basically in a horizontal receiving state. When the harvester operates on a slope and causes the rear frame 4 to tilt, the guide wheel 51 of the hopper 5 will roll along the arc-shaped hole 811 under the action of gravity, automatically adjusting to a new balance position (approximately horizontal), thereby preventing all the material from sliding to one side.
[0030] The front and rear sides of the hopper 5 are respectively provided with a front limiting plate 83 and a rear limiting plate 84. Both the front limiting plate 83 and the rear limiting plate 84 are provided with flexible buffer plates 85. The front and rear sides of the hopper 5 are in separable contact with the flexible buffer plates 85.
[0031] Specifically, in order to limit the swing range of the hopper 5 and buffer the impact, a front limiting plate 83 and a rear limiting plate 84 are respectively installed on the support platform 8 in the front and rear directions of the hopper 5. Flexible buffer plates 85 made of rubber or other materials are attached to the limiting plates. The hopper 5 will come into contact with these flexible buffer plates 85 during the swinging process, so as to achieve soft limiting.
[0032] A rear box plate 52 is hinged to the top rear side of the hopper 5, and a pin 53 for locking the rear box plate 52 is provided on the side of the hopper 5. The rear box plate 52 and the pin 53 are detachably connected.
[0033] A front crossbeam 11 is fixedly installed on the bottom side of the front frame 1, and a rear crossbeam 41 is rotatably installed on the rear frame 4. A longitudinal beam 12 is provided between the front crossbeam 11 and the rear crossbeam 41. One end of the longitudinal beam 12 is hinged to the front crossbeam 11, and the other end of the longitudinal beam 12 is hinged to the rear crossbeam 41.
[0034] Both the front drive wheel 6 and the rear drive wheel 7 are tracked drive wheels.
[0035] A rear panel 52 is hinged to the top rear side of the hopper 5, and a movable latch 53 is installed on the side wall of the hopper 5. During normal operation, the latch 53 locks the rear panel 52 closed. When unloading is required, the latch 53 is pulled out, and the rear panel 52 flips downward and opens under the weight of the material or under external force, completing the unloading.
[0036] During operation, the harvested crops from the harvester head 3 are sent to the conveyor belt 2, where they are lifted and thrown into the hopper 5. Thanks to the relative mobility of the front and rear frames 4 and the adaptive leveling function of the hopper 5, the machine can travel and operate stably even in uneven fields. The material in the hopper 5 is kept evenly distributed and finally unloaded by opening the rear panel 52.
[0037] By setting up automatic leveling of the front and rear frames 4 and the hopper 5 with active connection, the harvester can maintain the stability of the machine body on complex terrain, while ensuring that the hopper 5 is basically level and the material is evenly distributed, which improves the safety and efficiency of operation. The tilt angle of the hopper 5 can be adaptive or actively adjusted by the electric cylinder 82, so as to carry out the unloading operation. The harvester has strong adaptability to different terrains.
[0038] The front frame 1 and the rear frame 4 are connected by multiple hinge points, and with the tracked drive wheels, the whole machine has excellent contour-following ability and passability, which can effectively cope with harvesting operations in irregular plots such as hills and mountains, and further improve the adaptability to different terrains.
[0039] Technical features not described in detail in this solution are based on conventional operations and general understanding of those skilled in the art, and are therefore not elaborated upon here. Technical features not described in this utility model can be implemented using existing technology, and will not be repeated here. Of course, the above description is not intended to limit this utility model, nor is it limited to the examples given above. Any changes, modifications, additions, or substitutions made by those skilled in the art within the scope of this utility model should also fall within the protection scope of this utility model.
