Description

Technical Field

[0001] The utility model relates to a double-output agricultural operation machine. Background Art

[0002] A double-output agricultural operation machine is a tillage device in which a walking system and an operation system are distributed along a direction parallel to the tillage advancing direction. According to different tillage requirements, it can be specifically divided into two types: one tillage type is that when tilling forward normally, the operation system is in front of the walking system; the other tillage type is that when tilling forward normally, the operation system is behind the walking system. In order to improve the use safety of the double-output agricultural operation machine, when the walking system switches to reverse gear, it is necessary to control the operation system to stop working.

[0003] Chinese patent document CN219583953U discloses a double-output agricultural operation machine, including a transmission case, wherein a walking transmission mechanism and an operation transmission mechanism are arranged inside the transmission case; the walking transmission mechanism includes a walking control mechanism for controlling the walking transmission mechanism to perform a backward operation, the operation transmission mechanism includes an operation control mechanism for controlling the on-off of operation power, the walking control mechanism and the operation control mechanism are linked and coordinated, and when the walking control mechanism controls the walking transmission mechanism to perform a backward operation, the operation control mechanism controls the operation transmission mechanism to perform an operation power disconnection operation. Specifically, the solution of the prior art mainly disconnects the operation power by pushing the operation fork shaft to slide when performing a reverse gear sliding operation through the walking fork shaft.

[0004] The solution of the above prior art has high requirements for manufacturing tolerances, so the process requirements are high, otherwise it is easy to have a problem of poor linkage effect in actual use. In addition, the solution of the prior art mainly enables the double-output agricultural operation machine to meet the tillage requirements when the operation system is behind the walking system, and cannot enable the double-output agricultural operation machine to meet the tillage requirements when the operation system is in front of the walking system. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a double-output agricultural operation machine to solve the problem of poor linkage effect that easily occurs in the double-output agricultural operation machine in the prior art.

[0006] To achieve the above purpose, the basic scheme of the utility model provides a double-output agricultural operation machine, including a machine body, the machine body includes a walking system and an operation system, the walking system is provided with a walking control arm for switching the walking driving direction between facing the operation system and away from the operation system, the operation system is provided with an operation control arm for controlling the on-off of operation power, and a linkage member for unidirectionally driving the operation control arm by the walking control arm to disconnect the operation power is connected between the walking control arm and the operation control arm.

[0007] The beneficial effects of this basic solution are as follows: The traveling drive direction of the dual-output agricultural operation machine can be divided into a forward direction and a reverse direction according to the usage state. By connecting a linkage member for unidirectionally driving the operation control arm to the traveling control arm, when the traveling control arm adjusts the traveling drive direction of the dual-output agricultural operation machine to the reverse direction, the traveling control arm drives the operation control arm to move through the linkage member, thereby disconnecting the operation power. This improves the linkage effect between the traveling control arm and the operation control arm, and further improves the safety of the dual-output agricultural operation machine. Through the setting of unidirectional drive, the traveling control arm will only drive the operation control arm to move when the traveling drive direction is adjusted to the reverse direction, and when the traveling control arm adjusts the traveling drive direction to the forward direction, it will not drive the operation control arm to move, thereby reducing the influence of the traveling control arm on the operation power when the traveling drive direction is the forward direction.

[0008] Preferably, the linkage member is a flexible connection member. The flexible connection member mainly transmits tensile force. With such a setting, when the traveling control arm performs a reverse gear operation, it can drive the operation control arm to move through the linkage member to disconnect the power, and when the traveling control arm performs a forward gear operation, the traveling control arm will not drive the operation control arm to move through the linkage member, thereby avoiding the influence of the dual-output agricultural operation machine on the operation transmission during the forward gear operation.

[0009] Preferably, a first mounting position for connecting a linkage member to disconnect the operation power when the walking driving direction is away from the operation system is provided on the walking control arm. A second mounting position for connecting a linkage member to disconnect the operation power when the walking direction is towards the operation system is also provided on the walking control arm. The first mounting position or the second mounting position is connected to the linkage member. With such a setting, when the forward direction of the walking drive of the dual-output agricultural operation machine is towards the operation system, then the direction away from the operation system is the reverse direction. In this state, the linkage member is connected to the first mounting position. Thus, when the walking drive direction of the dual-output agricultural operation machine is switched to the reverse direction, that is, switched to reverse gear, the walking control arm drives the operation control arm to move through the first mounting position and the linkage member to disconnect the operation power, thereby realizing automatic disconnection of the operation power when the dual-output agricultural operation machine is in reverse gear and improving the safety during reverse gear operation. When the forward direction of the walking drive of the dual-output agricultural operation machine is away from the operation system, then the direction towards the operation system is the reverse direction. In this state, the linkage member is connected to the second mounting position. Thus, when the walking drive direction of the dual-output agricultural operation machine is switched to the reverse direction, that is, switched to reverse gear, the walking control arm drives the operation control arm to move through the second mounting position and the linkage member to disconnect the operation power, thereby realizing automatic disconnection of the operation power when the dual-output agricultural operation machine is in reverse gear and improving the safety during reverse gear operation. It can be seen from this that with this solution, without changing the basic structures of the walking system and the operation system of the dual-output agricultural operation machine, by simply making the linkage member select to connect to the first mounting position or the second mounting position according to the walking drive direction of the dual-output agricultural operation machine, it can be achieved that when the forward direction of the walking drive of the dual-output agricultural operation machine is either towards the operation system or away from the operation system, the operation power can be automatically disconnected during reverse gear operation. Therefore, the dual-output agricultural operation machine can be adjusted according to the tillage requirements of users (i.e., different forward directions of the walking drive) without changing the basic structure composition, forming two agricultural operation machines with different forward directions of the walking drive to meet different tillage requirements, while keeping the switching operation mode of the forward and reverse gears of the walking unchanged and ensuring the safety of reverse gear operation.

[0010] Preferably, the walking control arm is hinged to the body, and the first mounting position and the second mounting position are respectively located on both sides of the walking hinge portion of the walking control arm. With such a setting, the movement of the first mounting position and the second mounting position can be realized by swinging the walking control arm around the hinge point with the body, which is beneficial to improving the operation convenience.

[0011] Preferably, the operating system is provided with an operating sub-control arm for cutting off the power of the operating control arm and locking the cut-off state. With such a setting, the operating system can be kept in the state of cutting off the operating power without being affected by the traveling control arm, which is beneficial to achieving that the operating system is still in the power-off state when the traveling system is in the forward gear, so as to realize the separate output of the traveling power, and further beneficial to improving the safety of the dual-output agricultural working machine during the transfer.

[0012] Preferably, the operating sub-control arm and the operating control arm are respectively hinged to the body, and a stop rod for driving the operating control arm to swing to the operating power-off state and locking and positioning is fixedly arranged on the operating sub-control arm. With such a setting, it is convenient to drive and lock and position the operating control arm through the operating sub-control arm, which is beneficial to improving the operation convenience.

[0013] Preferably, the body is provided with a first operation installation position for making the handrail located on the side of the traveling system far from the operating system, and the body is also provided with a second operation installation position for making the handrail located on the side of the traveling system close to the operating system. With such a setting, the handrail can be installed and set accordingly according to the tillage needs, which is beneficial to improving the practicability. Description of the Drawings

[0015] Figure 2 It is a schematic diagram of an embodiment of a dual-output agricultural working machine of the present invention when the tillage tool is in the rear and the traveling wheel is in the front. Detailed Description of the Invention

[0016] The direction indicated by the arrow in the figure is the forward direction of the dual-output agricultural working machine during normal tillage. In the present invention, the traveling driving direction refers to the direction of the output end of the traveling system driving the traveling wheel to drive the traveling system to move on the ground relative to the position of the operating system.

[0017] In this solution, the flexible connecting member can also be selected as a chain-type connecting member, a multi-link type connecting member, etc.

[0018] The following is further detailed through specific embodiments:

[0019] The reference numerals in the accompanying drawings of the specification include: handrail 1, body 2, traveling control arm 3, first installation position 31, second installation position 32, traveling hinge part 33, linkage member 4, operating control arm 5, operating hinge part 51, stop rod 6, operating sub-control arm 7, traveling wheel 8, tillage tool 9.

[0020] The embodiment is basically as shown in the attachedFigure 1 and Figure 2 As shown in Figure 2 , a dual-output agricultural operation machine includes a machine body 2, and the machine body 2 includes a traveling system and an operation system. In this embodiment, the machine body 2 is mainly composed of the outer shell of the traveling system and the outer shell of the operation system. The traveling system is provided with a traveling control arm 3 for switching the traveling driving direction between facing the operation system and away from the operation system. In this embodiment, the traveling control arm 3 is preferably hinged to the machine body 2, and the switching operation of the traveling driving direction is realized by the swinging of the traveling control arm 3 around the traveling hinge portion 33. For example, the shifting movement of the shifting gear of the traveling system is realized by the swinging of the traveling control arm 3, so as to change the traveling driving direction of the traveling system.

[0021] The operation system is provided with an operation control arm 5 for controlling the on / off of the operation power. In this embodiment, the operation control arm 5 is preferably hinged to the machine body 2. Specifically, the operation control arm 5 is hinged to the machine body 2 through the operation hinge portion 51, and the on / off switching of the operation power is realized by the swinging of the operation control arm 5. For example, the swinging of the operation control arm 5 is used to control the clutch mechanism of the operation system to switch between the engaged state and the disengaged state, so as to realize the on / off control of the operation power.

[0022] A linkage 4 is connected between the operation control arm 5 and the traveling control arm 3, which facilitates the swinging of the operation control arm 5 driven by the swinging of the traveling control arm 3; a first mounting position 31 is provided on the traveling control arm 3 for connecting the linkage 4 to disconnect the operation power when the traveling driving direction is away from the operation system; a second mounting position 32 is also provided on the traveling control arm 3 for connecting the linkage 4 to disconnect the operation power when the traveling direction is facing the operation system. During assembly, the linkage 4 can only be connected and set at one of the first mounting position 31 and the second mounting position 32. In this embodiment, the first mounting position 31 and the second mounting position 32 are respectively located on both sides of the traveling hinge portion 33 of the traveling control arm 3, so that when the traveling control arm 3 swings in different directions, there is a mounting position that can be connected to the linkage 4 and exert a pulling force on the linkage 4. In this embodiment, the linkage 4 is preferably a flexible connecting member, such as a connecting member made of steel wire rope.

[0023] The operation system is provided with an operation sub-control arm 7 for locking and positioning the operation control arm 5 when it is in the state of disconnecting the operation power. In this embodiment, the operation sub-control arm 7 is hinged to the machine body 2, and a stop rod 6 for driving the operation control arm 5 to swing to the operation power-off state and locking and positioning is fixedly provided on the operation sub-control arm 7. By the swinging of the operation sub-control arm 7, the operation control arm 5 can be driven by the stop rod 6 to swing towards the operation power-off position and finally be locked and positioned in the operation power-off state, which is convenient for operation.

[0024] The machine body 2 is provided with a first operation installation position for making the handrail 1 located on the side of the traveling system away from the operation system, and the machine body 2 is also provided with a second operation installation position for making the handrail 1 located on the side of the traveling system close to the operation system. Thus, during assembly, it is convenient for the handrail 1 to select a specific operation installation position for assembly according to tillage needs, thereby improving the assembly convenience.

[0025] During assembly, after the traveling system and the operation system are respectively assembled on the machine body 2, by connecting the handrail 1 to the first operation installation position, the handrail 1 is located on the side of the traveling system away from the operation system. At the same time, one end of the linkage 4 is connected to the first installation position 31 of the traveling control arm 3, and the other end of the linkage 4 is connected to the operation control arm 5. At this time, the dual-output agricultural working machine forms a working machine of the tillage type with the forward direction of the traveling drive being towards the operation system (as Figure 1 shown). That is, when the dual-output agricultural working machine tills, the tillage tool 9 connected to the output end of the operation system is located in the front, while the traveling wheel 8 connected to the output end of the traveling system is located in the rear, and the operator is located on the side of the traveling wheel 8 away from the tillage tool 9. When the dual-output agricultural working machine is switched to reverse through the traveling control arm 3, that is, the counterclockwise swing of the traveling control arm 3 will drive the operation control arm 5 to swing counterclockwise through the first installation position 31 and the linkage 4 (in this embodiment, the counterclockwise swing of the operation control arm 5 is the power disconnection operation of the operation system), thereby disconnecting the operation power of the operation system and stopping the tillage tool 9 from working, improving the safety during reverse operation.

[0026] When it is necessary to make the dual-output agricultural working machine form a working machine of the tillage type with the traveling wheel 8 in the front and the tillage tool 9 in the rear, connect the handrail 1 to the second operation installation position and connect the linkage 4 to the second installation position 32 of the traveling control arm 3, then the dual-output agricultural working machine can form a working machine of the tillage type with the traveling wheel 8 in the front and the tillage tool 9 in the rear (as Figure 2 shown). When the dual-output agricultural working machine is switched to reverse through the traveling control arm 3, the clockwise swing of the traveling control arm 3 will drive the operation control arm 5 to swing counterclockwise through the second installation position 32 and the linkage 4 (in this embodiment, the counterclockwise swing of the operation control arm 5 is the power disconnection operation of the operation system), thereby disconnecting the operation power of the operation system and stopping the tillage tool 9 from working, improving the safety during reverse operation.

[0027] In both tillage types, the dual-output agricultural working machine can disconnect the working power by operating the working sub-control arm 7 alone to make the working control arm 5 swing counterclockwise. Therefore, with this solution, when switching and adjusting between the working machines of the two tillage types where the driving wheels 8 are in the front and the tillage tools 9 are in the rear and where the tillage tools 9 are in the front and the driving wheels 8 are in the rear, it can be achieved only by adjusting the assembly positions of the handrail 1 and the linkage 4, and the safety of the working machines of the two tillage types during reverse operation can be ensured, thus significantly reducing the manufacturing cost and improving the usability.

[0028] The above are only the embodiments of the present invention, and common knowledge such as the specific structures and characteristics known in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent.
