Description

Technical Field

[0001] The invention relates to the technical field of harvesters, and in particular to a harvester chassis structure and a harvester. Background Art

[0002] A harvester is an agricultural machine that combines mowing, collecting, chopping and throwing, and is mainly used for harvesting crops. In modern agriculture, harvesters have become an important tool for increasing crop yields, reducing production costs and alleviating the labor intensity of farmers. The harvester chassis is an important part of the harvester. It carries the weight of the entire machine and provides it with stable walking and steering capabilities. The general harvester chassis structure includes crawler, wheeled and triangular crawler. The crawler chassis can keep the harvester stable on muddy, slippery or uneven ground, and has excellent off-road capabilities and terrain adaptability. It is more suitable for use in complex terrains such as paddy fields and swamps, as well as farmland that requires high-intensity operations.

[0003] For example, in the prior art, the patent with the authorization announcement number CN211982706U discloses a chassis assembly structure of a miniature harvester, including a chassis frame, a gearbox assembly installed on the chassis frame, the gearbox assembly having a power output device, a driving wheel shaft installed through the power output device, and driving wheels installed at both ends of the driving wheel shaft; a track guide wheel assembly, a track roller assembly and a track tensioning wheel assembly are installed on the chassis frame below the driving wheel, and the driving wheel, the track guide wheel assembly, the track roller assembly and the track tensioning wheel assembly on the same side of the chassis frame are driven by a track; and the installation position of the driving wheel, the track guide wheel assembly, the track roller assembly and the track tensioning wheel assembly enables the track to be supported as a quadrilateral, forming an approach angle in the direction of the track travel. The above device adopts a quadrilateral wide-body integral track, the ground pressure of the whole machine is small, and the approach angle is set, which improves the climbing ability of the whole machine, and can effectively solve the technical problem that the harvester sinks in winter paddy fields and cannot walk.

[0004] However, the above-mentioned harvester chassis structure has certain defects when in use: when using the crawler harvester chassis for operation, once encountering a situation where steering or turning is required in a narrow space, the driver needs to accurately control the movement state of the two tracks and rely on the speed difference between the left and right tracks to achieve the steering action. This steering method often causes sliding between the steering direction and the forward path, and the resistance increases significantly when turning, making it difficult to accurately determine the turning radius, which in turn causes troubles in the harvester's steering operation; at the same time, because this steering mode has high requirements for driving skills, it increases the difficulty of operation for the driver, increases the operating requirements for the driver, and has poor applicability.

[0017] (2) By using the electric push rod and the support block to cooperate with each other, the driver can adjust the stability of the support seat by himself to ensure that the support seat can provide stable support for the harvester during the turning process of the harvester to prevent the harvester from overturning; at the same time, the support block will form a stable contact point with the ground, thereby dispersing and balancing the pressure on the support seat;

[0018] (3) The cooperation between the detection component and the electric push rod realizes the automatic leveling and stabilization of the support seat, which brings convenience to the driver. While ensuring the stability of the harvester when turning, it reduces the driver's operating skills and experience requirements, reduces the difficulty of the driver to get started, and improves the overall practicality and applicability of the harvester;

[0019] (4) The reset mechanism ensures that the sliding rod can be quickly and stably reset after being subjected to external force, thereby maintaining the sensitivity and accuracy of the detection component. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] See also Figures 1 to 11 A harvester chassis structure includes a chassis bracket 2, a connecting shell 3 is fixedly connected to the bottom surface of the chassis bracket 2, a connecting groove 4 is opened in the connecting shell 3, a driven shaft 5 and a driving shaft 6 are rotatably connected in the connecting groove 4, a driven wheel 7 and a driving wheel 8 are fixedly connected in the middle of the driven shaft 5 and the driving shaft 6 respectively, the bottom end of the driving shaft 6 penetrates the bottom surface of the connecting shell 3 and is fixedly connected to a motor 9, the motor 9 is fixedly connected to the bottom surface of the connecting shell 3, the bottom end of the driven shaft 5 penetrates the bottom surface of the connecting shell 3 and is fixedly connected to a lifting cylinder 10, the output end of the lifting cylinder 10 is fixedly connected to a lifting rod 11, the bottom end of the lifting rod 11 is fixedly connected to a support seat 12, and the four corners of the support seat 12 are connected with stabilizing components.

[0034] The chassis structure of the harvester in the present invention is that when the harvester needs to turn in a narrow area, the driver starts the lifting cylinder 10, and the lifting cylinder 10 will drive the support seat 12 to move downward through the lifting rod 11. When the support seat 12 contacts the ground, the lifting cylinder 10 will reversely push the chassis bracket 2 and the harvester connected thereto to rise, so that the crawler connected to the chassis bracket 2 is separated from the ground. Then the driver controls the motor 9 to rotate, and the motor 9 will drive the driving wheel 8 to rotate through the driving shaft 6, thereby driving the driven wheel 7 and the driven shaft 5 to rotate. Due to the gravity of the harvester and the friction force of the ground, the support seat 12 and the lifting cylinder 10 cannot rotate, which causes the driven wheel 7 and the driven shaft 5 to be unable to rotate. Driven by the motor 9, the driving wheel 8 will rotate around the outer wall of the driven wheel 7, thereby driving the connecting shell 3 and the chassis bracket 2 thereon and the harvester to rotate. The rotation angle of the harvester is adjusted by controlling the rotation angle of the motor 9. When the harvester rotates to the required angle, the lifting cylinder 10 retracts the lifting cylinder 10. The rod 11 is lowered, and the crawler track gradually descends to contact the ground, and then the support seat 12 is separated from the ground, so that the harvester can complete the on-the-spot turning; the motor 9 and the lifting cylinder 10 cooperate with each other, so that the driver can realize the on-the-spot turning of the harvester, and by accurately controlling the rotation angle of the motor 9, the driver can realize the precise control of the rotation angle and the steering position of the harvester. The on-the-spot turning ability enables the harvester to adapt to the complex working environment more quickly, reduces the turning time and path adjustment, and thus improves the working efficiency. Compared with the existing method of steering by crawler speed difference, the present invention reduces the requirements for the driver's operating skills, reduces the operating difficulty, reduces the difficulty of the driver's use, and improves the overall practicality and applicability of the harvester. At the same time, turning on the spot means that the turning radius is almost zero, so that the harvester can operate freely in a narrow or confined space, without worrying about the problem of insufficient space due to an excessively large turning radius, and reduces the turning time and path adjustment, thereby significantly improving the working efficiency.

[0035] As a preferred technical solution of the present invention, the stabilizing component includes a support block 13, an electric push rod 15, and a support rod 16. The four corners of the surface of the support seat 12 are fixedly connected with the electric push rods 15, and the output end of each electric push rod 15 is fixedly connected with the support rod 16. The support rod 16 is slidably connected to the support seat 12. The bottom end of the support rod 16 penetrates the support seat 12 and is fixedly connected with the support block 13. The middle part of the support seat 12 is connected with a detection component.

[0036] Specifically, if the ground is obviously uneven, such as in the presence of puddles, ditches, etc., when the support seat 12 contacts the ground, the support force may be uneven due to the uneven distribution of contact points. This uneven support force may cause the harvester to tilt or shake when turning or stationary, affecting the stability and safety of the operation. At this time, the driver can control the extension and retraction of the four electric push rods 15 through the control system. The four electric push rods 15 are respectively located at the four corners of the support seat 12. Through their coordinated work, the height of each support rod 16 can be adjusted independently. As the electric push rod 15 extends, the support rod 16 will drive the support block 13 to gradually move downward until it is in close contact with the ground. When the four support blocks 13 form a stable support with the ground, they jointly provide a more stable and balanced support surface for the harvester. This not only helps to reduce the tilt and shaking of the harvester when turning or stationary, but also improves its operating stability and safety on uneven ground; by using the electric push rod 15 and the support block 13 to cooperate with each other, the driver can adjust the stability of the support seat 12 by himself to ensure that during the turning process of the harvester, the support seat 12 can provide stable support for the harvester to prevent the harvester from overturning; at the same time, the support block 13 will form a stable contact point with the ground, thereby dispersing and balancing the pressure on the support seat 12.

[0037] As a preferred technical solution of the present invention, the detection component includes a connecting block 17, a balancing ball 19, a sliding rod 21, a connecting rod 22, a resistor plate 23, a current collection module 26, a battery module 27 and a conductive wire 28. The middle of the bottom surface of the support seat 12 is fixedly connected to the connecting block 17, and a moving groove 18 is opened in the middle of the connecting block 17. The balancing ball 19 is slidably connected in the moving groove 18. Four sliding grooves 20 are equidistantly opened on the inner wall of the moving groove 18. A sliding rod 21 is slidably connected in each sliding groove 20. One end of the sliding rod 21 is in contact with the outer wall of the balancing ball 19, and the other end is fixedly connected to the outer wall of the balancing ball 19. A connecting rod 22 is connected, and a plurality of mounting grooves 31 corresponding to the position of the connecting rod 22 are opened in the connecting block 17. The connecting rod 22 and the connecting block 17 are vertically arranged. The resistor plate 23 is fixedly connected in the mounting groove 31. One end of the connecting rod 22 is in contact with the surface of the resistor plate 23. The current acquisition module 26 and the battery module 27 are fixedly connected in the mounting groove 31. The connecting rod 22 and the current acquisition module 26, the current acquisition module 26 and the battery module 27, and the battery module 27 and the resistor plate 23 are all electrically connected through a conductive wire 28. A reset component is connected to the outer wall of the sliding rod 21.

[0038] Specifically, when the driver uses the lifting cylinder 10 to lower the support seat 12, the detection component will automatically detect the horizontal condition of the support seat 12, so that the electric push rod 15 can automatically move the support block 13 to stabilize the harvester; when the support seat 12 is lowered, the support block 13 will contact the ground. If there are puddles or ditches on the ground, the support seat 12 will tilt. At this time, under the action of gravity, the balancing ball 19 will tilt toward the side with the puddle or ditch, and will squeeze the two sliding rods 21 on this side, so that the sliding rod 21 moves in the sliding groove 20, thereby driving the connecting rod 22 to slide. During the sliding process of the connecting rod 22, the connecting rod 22 contacts the resistor plate 23. The position of the resistor plate 23 will change. Since the connecting rod 22 and the current acquisition module 26, the current acquisition module 26 and the battery module 27, and the battery module 27 and the resistor plate 23 are electrically connected through the conductive wire 28, as the contact position of the connecting rod 22 and the resistor plate 23 changes, the resistance value of the resistor plate 23 connected to the circuit will also change. Since the battery module 27 provides a stable power supply for the entire circuit, according to Ohm's law, when the resistance changes, the current in the circuit will change synchronously. The current acquisition module 26 will accurately measure this current change and transmit the measurement result to the control module. After receiving the data from the current acquisition module 26, the control module will immediately perform analysis and processing. By judging the increase or decrease of the current, the control module can accurately infer the tilt direction and tilt degree of the balancing ball 19, and then the control module will automatically adjust the electric push rod 15 located on the tilt path of the balancing ball 19 according to this information. After receiving the command of the control module, the electric push rod 15 will start to extend and retract, thereby driving the support rod 16 and the support block 13 to rise and fall. By accurately controlling the extension and retraction amount of the electric push rod 15, the tilt angle of the support seat 12 can be gradually adjusted until it returns to a horizontal state. When the support seat 12 reaches a predetermined horizontal position, the current in the circuit will also return to a predetermined range. At this time, the current acquisition module 26 will measure the current value again and feed the result back to the control module for verification. If the current value meets the preset standard, it indicates that the support seat 12 has stabilized, and the coordinated work of the detection component and the electric push rod 15 is completed.

[0039] By utilizing the cooperation between the detection component and the electric push rod 15, the support seat 12 is automatically leveled and stabilized, which brings convenience to the driver. While ensuring the stability of the harvester when turning, it reduces the driver's operating skills and experience requirements, reduces the driver's difficulty in getting started, and improves the overall practicality and applicability of the harvester.

[0040] As a preferred technical solution of the present invention, the reset assembly includes a reset plate 29 and a reset spring 30. The reset plate 29 is fixedly connected to the outer wall of the sliding rod 21. A reset groove 32 corresponding to the position of the reset plate 29 is opened in the connecting block 17. The reset spring 30 is fixedly connected between the reset plate 29 and the inner wall of the reset groove 32.

[0041] Specifically, when the sliding rod 21 is squeezed by the balancing ball 19 and moves, the reset spring 30 will be compressed and store energy. Once the squeezing force of the balancing ball 19 disappears or decreases, the reset spring 30 will quickly release the stored energy and push the reset plate 29 and the sliding rod 21 back to their original positions along the path of the reset groove 32. The reset mechanism ensures that the sliding rod 21 can be quickly and stably reset after being subjected to external force, thereby maintaining the sensitivity and accuracy of the detection component.

[0042] As a preferred technical solution of the present invention, a protective shell 14 is fixedly connected to the outer wall of the motor 9 , and the protective shell 14 is fixedly connected to the bottom surface of the connecting shell 3 .

[0043] Specifically, the protective shell 14 can effectively prevent external factors such as dust, moisture, and debris from invading the motor 9, thereby extending the service life of the motor 9 and improving its working reliability.

[0044] As a preferred technical solution of the present invention, a conductive ball 24 is fixedly connected to one end of the connecting rod 22 , and a sliding groove 25 corresponding to the position of the conductive ball 24 is opened on the surface of the resistor plate 23 .

[0045] Specifically, the conductive ball 24 and the slide groove 25 can improve the stability of the electrical connection between the connecting rod 22 and the resistor plate 23 and ensure circuit connectivity. The spherical design of the conductive ball 24 makes its contact area with the slide groove 25 larger and the contact closer, thereby reducing the current fluctuation and failure risk caused by poor contact.

[0046] As a preferred technical solution of the present invention, one end of the sliding rod 21 close to the balancing ball 19 is spherical.

[0047] Specifically, since the spherical surface design has good guiding and adaptability, it can ensure that the balancing ball 19 always maintains stable contact with the sliding rod 21 during the rolling process, thereby reducing errors and failures caused by poor contact.

[0048] As a preferred technical solution of the present invention, a wear-resistant layer 33 is fixedly connected to the bottom surface of the support block 13 .

[0049] Specifically, the wear-resistant layer 33 is made of a material with high hardness and high wear resistance, such as high-strength alloys, ceramics or special composite materials. These materials have excellent wear resistance, corrosion resistance and impact resistance, and can effectively resist friction and wear from the ground, thereby extending the service life of the support block 13. At the same time, in complex terrains, such as muddy, rugged or sandy roads, the wear-resistant layer 33 not only provides sufficient hardness to resist ground wear, but also increases the friction with the ground through the special texture or structure on its surface, thereby improving the grip and stability of the support block 13.

[0050] The present invention further provides a harvester, comprising a harvester body 1 , wherein the harvester body 1 comprises any of the above-mentioned harvester chassis structures, and a control module is installed in the harvester body 1 .

[0051] Specifically, since the harvester chassis structure according to the embodiment of the present invention has the above-mentioned technical effects, the harvester body 1 according to the embodiment of the present invention should also have corresponding technical effects, that is, the harvester body 1 of the present invention adopts the harvester chassis structure, so that the driver can steer the harvester more conveniently, which reduces the requirements for the driver's operating skills, reduces the difficulty of operation, reduces the difficulty of the driver's getting started, and improves the overall practicality and applicability of the harvester; a switch and a processing system are installed on the control module, and the control module is used to control the lifting cylinder 10 and the electric push rod 15, as well as information processing of the detection component. A display module can also be added to the control module, and an image is constructed by processing the current information to display the tilt state of the excavator in real time, so that the driver can observe and judge it easily.

[0052] Of course, for those skilled in the art, other structures of the harvester body 1 and its working principle can be understood and implemented, and will not be described in detail in the present invention.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
