[0030] Please see attached Figure 1-3 In one embodiment of the present invention, a transversely movable rotary tiller is provided, comprising a guide rail assembly 10, a three-point suspension seat 20, a drive assembly 30 and a rotary tiller body 40. First of all, it should be noted that the longitudinal direction in the present application refers to the extension direction along the travel path of the rotary tiller, the transverse direction refers to the vertical direction of the longitudinal direction in the horizontal plane, and the front end refers to the forward direction along the rotary tillage. Please refer to the markings in the attached drawings for details; and it is different from the rotary tiller in the prior art, which is prone to the situation that the corners cannot be tilled in place during operation, but because the suspension seat connected to the tractor is usually fixed to the rotary tiller, and the whole machine is relatively large and inconvenient to move horizontally, and cannot be adjusted horizontally, which affects the rotary tillage effect and leads to insufficient rotary tillage. The present application solves the above-mentioned defects in the prior art by providing a transversely movable rotary tiller, as follows:

[0031] The rotary tiller body 40 is protruded upward to form two mounting frames 411 arranged opposite to each other in the transverse direction. The guide rail assembly 10 extends in the transverse direction and is connected between the two mounting frames 411. A transverse channel is opened at the bottom end of the three-point suspension seat 20. The front end of the three-point suspension seat 20 is used to connect with an external tractor. The three-point suspension seat 20 is connected to the guide rail assembly 10 and the guide rail assembly 10 is movably passed through the transverse channel in the transverse direction. The connecting end of the driving assembly 30 is connected to the three-point suspension seat 20. The driving end of the driving assembly 30 is telescopically arranged in the transverse direction and connected to the mounting frame 411.

[0032] Specifically, the transversely movable rotary tiller in the present application includes a guide rail assembly 10, a three-point suspension seat 20, a drive assembly 30 and a rotary tiller body 40. The guide rail assembly 10 is used to guide during driving and movement to avoid displacement during movement, so it extends laterally; the three-point suspension seat 20 is used to connect with an external tractor so as to be pulled by the external tractor as a power source during rotary tillage, and only after it is fixed to the external tractor can the rotary tiller body 40 be relatively movable; the drive assembly 30 is used to drive the rotary tiller body 40 to move.

[0033] The mounting frame 411 protruding upwardly from the rotary tiller body 40 is used for mounting the guide rail assembly 10 so that the guide rail assembly 10 is horizontally placed between the two mounting frames 411, and a transverse channel is provided at the bottom end of the three-point suspension seat 20, through which the guide rail assembly 10 can be movably passed, and the direction of movement can be further limited to the transverse direction after being matched with the guide rail assembly 10 extending in the transverse direction. It can be understood that when the tractor is fixed, the three-point suspension seat 20 connected to the tractor It is also fixed. Relatively speaking, the guide rail assembly 10 movably passing through the transverse channel can be moved laterally, thereby synchronously driving the entire rotary tiller body 40 to move laterally. Therefore, the connecting end of the driving assembly 30 is connected to the three-point suspension seat 20, and the fixed three-point suspension seat 20 is used as the driving base 110, and the driving end is telescopically arranged in the transverse direction and connected to the mounting frame 411, thereby pulling the rotary tiller body 40 to move laterally, so as to achieve the purpose of transversely adjusting the rotary tilling position of the rotary tiller and ensure that the rotary tilling is in place.

[0034] As a preferred embodiment of the present invention, the guide rail assembly 10 includes two bases 110, a first guide rail 120 and a second guide rail 130 arranged opposite to each other in the transverse direction, the two bases 110 are respectively connected to the inner sides of the mounting frame 411, the first guide rail 120 and the second guide rail 130 are arranged at intervals in the longitudinal direction and are both connected between the two bases 110, the first guide rail 120 is movably passed through the transverse channel in the transverse direction, and the driving end of the driving assembly 30 is connected to the base 110.

[0035] It should be noted that the base 110 is used for the first guide rail 120 and the second guide rail 130 to be installed and connected with the mounting frame 411, and the two bases 110 are respectively connected to the inner sides of the mounting frames 411, so that the first guide rail 120 and the second guide rail 130 can be horizontally placed between the two mounting frames 411 through the base 110, and the first guide rail 120 is used to cooperate with the three-point suspension seat 20 to form a transverse track, so the first guide rail 120 is movably passed through the transverse channel in the transverse direction, and the driving end of the driving assembly 30 is connected to the base 110 installed on the inner side of the mounting frame 411 at this time; the second guide rail 130 is used for connection with the remaining guide components.

[0036] As a preferred embodiment of the present invention, it also includes two guide assemblies, each of which includes a sleeve 131 and a connecting plate 132, the sleeve 131 is sleeved on the second guide rail 130, the connecting plate 132 is connected to the sleeve 131, each connecting plate 132 is connected to a corresponding side connecting portion 230, the connecting end of the driving assembly 30 is connected to the connecting plate 132, and a through hole is also provided on the side connecting portion 230 close to the driving end of the driving assembly 30.

[0037] It is worth mentioning that the guide assembly is used to further guide the lateral movement of the entire machine, and includes a sleeve 131 and a connecting plate 132. The sleeve 131 is used to be sleeved on the second guide rod, so that a lateral movement guide limit is formed under the cooperation of the sleeve 131 and the second guide rod, and the transverse channel and the first guide rod. The connecting plate 132 is used to connect the sleeve 131 with the side connecting part 230, so as to ensure that the sleeve 131 will not move when the three-point suspension seat 20 is fixed, thereby forming an effect that only the guide rail assembly 10 drives the rotary tiller body to move relative to each other. After the side connecting part 230 and the connecting plate 132 are connected, in order to avoid affecting the extension and retraction of the driving end, a through hole needs to be opened on the side connecting part 230 close to the driving end of the driving assembly 30 to facilitate the extension and retraction of the driving end.

[0038] As a preferred embodiment of the present invention, the three-point suspension seat 20 includes a suspension bracket 210, an upper connecting part 220 and two side connecting parts 230, the bottom of the suspension bracket 210 is provided with the transverse channel, the upper connecting part 220 is protruded from the top of the suspension, the two side connecting parts 230 are arranged opposite to each other on both sides of the bottom end of the suspension bracket 210 in the transverse direction, and the side connecting part 230 is provided with a through hole arranged corresponding to the transverse channel.

[0039] It should be noted that the suspension bracket 210 is an integral part of the entire suspension seat, which is in a convex shape, so that the upper connecting part 220 and the two side connecting parts 230 are connected from the top and the two sides respectively, thereby forming a triangular distribution, which is more stable when connected. The top of the side connecting part 230 is convex to the rear end to facilitate connection with the connecting plate 132 on the sleeve 131, and the bolt connection method is adopted for easy disassembly and replacement; and since the side connecting part 230 is installed on both sides of the suspension bracket 210, in order to facilitate the penetration of the first guide rail 120, a through hole corresponding to the transverse channel is opened on the side connecting part 230. The corresponding arrangement here means that the through hole is consistent in size and shape with the transverse channel and is coaxially arranged.

[0040] As a preferred embodiment of the present invention, the connection end of the driving assembly 30 is hinged to the connecting plate 132 , and the driving end of the driving assembly 30 is hinged to the base 110 .

[0041] It is worth noting that the use of hinged connection can avoid rigid damage caused by small displacement under rigid connection when driving and moving, which can improve the offset adaptability of the structure at the connection and increase the service life of the structure.

[0042] Furthermore, the upper connecting portion 220 and the side connecting portion 230 are both fixedly connected to an external tractor by bolts.

[0043] It should be noted that when connected to an external tractor in this way, disassembly and assembly are convenient, and the connection is tight to ensure the fixing effect of the three-point suspension seat 20 and the tractor during lateral movement.

[0044] Furthermore, the driving assembly 30 adopts a hydraulic cylinder.

[0045] It should be understood that the hydraulic cylinder can provide a relatively large pressure thrust and is a commonly used drive component 30. In addition, in the present application, in order to achieve push and pull back and forth, a double-acting cylinder may be further used.

[0046] Furthermore, the rotary tiller body 40 includes a frame 410 and a rotary tiller assembly 420 , the rotary tiller assembly 420 is rotatably connected to the bottom of the frame 410 , and the mounting frame 411 is protruded from the top of the frame 410 .

[0047] It should be noted that the frame 410 is used for installing the rotary tillage assembly 420, and the rotary tillage assembly 420 is composed of a rotating shaft and a rotary tillage blade, which is well known to those skilled in the art and will not be described in detail here. The mounting frame 411 is protruded from the top of the frame 410, so as to facilitate the installation of the guide rail assembly 10 on the top of the frame 410.

[0048] Furthermore, it also includes a limiting rod seat 412, which is connected to the front end of the frame 410, and the limiting rod seat 412 is adjustable in the vertical direction.

[0049] It should be noted that the limit rod seat 412 is used to limit the upper and lower position depth of the rotary tiller body 40 for vertical adjustment. It is connected to the front end of the frame 410, and adopts the form of a rod sleeve and a limit rod. The rod sleeve is fixedly connected to the frame 410, and the limit rod has a plurality of adjustment holes arranged at intervals along the vertical direction. The rod sleeve is also provided with an adjustment hole. In this way, when the target height position is reached, the adjustment hole can be aligned with a screw to limit the position, thereby completing the height adjustment; preferably, the spacing between each two adjacent adjustment holes is 25mm to 30mm, and technicians in this field can set it according to actual needs.

[0050] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
