[0030] Please see the appendix Figure 1-3 This utility model provides a laterally movable rotary tiller, comprising a guide rail assembly 10, a three-point suspension seat 20, a drive assembly 30, and a rotary tiller body 40. First, it should be noted that in this application, longitudinal refers to the direction extending along the rotary tiller's travel path, lateral refers to the vertical direction in the horizontal plane, and the front end refers to the forward direction along the rotary tilling movement; please refer to the accompanying drawings for details. Unlike existing rotary tillers, which often fail to fully till corners during operation, this utility model addresses these shortcomings by providing a laterally movable rotary tiller, as the suspension seat connected to the tractor is usually fixed to the tiller, and the large size of the machine makes lateral movement inconvenient and adjustment impossible, thus affecting the tilling effect and resulting in insufficient tilling.

[0031] The rotary tiller body 40 has two mounting brackets 411 that are arranged laterally opposite each other. The guide rail assembly 10 extends laterally and is connected between the two mounting brackets 411. The bottom end of the three-point suspension seat 20 has a transverse channel. 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 inserted through the transverse channel. The connecting end of the drive assembly 30 is connected to the three-point suspension seat 20. The driving end of the drive assembly 30 is laterally retractable and connected to the mounting brackets 411.

[0032] Specifically, the lateral rotary tiller in this 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 movement during drive to prevent deviation during movement, and therefore extends laterally. The three-point suspension seat 20 is used to connect to an external tractor so that it can be pulled by an external tractor as a power source during rotary tillage. At the same time, it is fixed to the external tractor so that the rotary tiller body 40 can move relatively. The drive assembly 30 is used to drive the rotary tiller body 40 to move.

[0033] The rotary tiller body 40 has an upwardly protruding mounting bracket 411 for mounting the guide rail assembly 10, allowing the guide rail assembly 10 to be placed horizontally between two mounting brackets 411. A transverse channel is provided at the bottom end of the three-point suspension seat 20, through which the guide rail assembly 10 can move movably. This channel, in conjunction with the laterally extending guide rail assembly 10, further restricts the direction of movement to the lateral direction. It is understood that when the tractor is stationary, the three-point suspension seat 20 connected to the tractor... The guide rail assembly 10, which is fixed and movable through the transverse channel, can move laterally, thereby synchronously driving the entire rotary tiller body 40 to move laterally. Therefore, the connecting end of the drive assembly 30 is connected to the three-point suspension seat 20, with the fixed three-point suspension seat 20 as the drive base 110, while the drive end is set laterally and connected to the mounting frame 411, thereby pulling the rotary tiller body 40 to move laterally, so as to achieve the purpose of adjusting the rotary tiller's rotary tillage position and ensuring that the rotary tillage is in place.

[0034] In a preferred embodiment of the present invention, the guide rail assembly 10 includes two bases 110 arranged laterally opposite each other, a first guide rail 120 and a second guide rail 130. The two bases 110 are respectively connected to the inner side of the mounting bracket 411. The first guide rail 120 and the second guide rail 130 are arranged longitudinally at intervals and are both connected between the two bases 110. The first guide rail 120 is movably inserted through the transverse channel. 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 to the mounting bracket 411. The two bases 110 are respectively connected to the inner side of the mounting bracket 411. Thus, the first guide rail 120 and the second guide rail 130 can be placed horizontally between the two mounting brackets 411 through the base 110. The first guide rail 120 is used to cooperate with the three-point suspension seat 20 to form a transverse track. Therefore, the first guide rail 120 is movably inserted through the transverse channel in the transverse direction. The driving end of the driving component 30 is then connected to the base 110 installed on the inner side of the mounting bracket 411. The second guide rail 130 is used for the connection of the other guiding components.

[0036] In a preferred embodiment of the present invention, two guide components are also included. Each guide component includes a bushing 131 and a connecting plate 132. The bushing 131 is sleeved on the second guide rail 130, and the connecting plate 132 is connected to the bushing 131. Each connecting plate 132 is connected to a side connecting part 230. The connecting end of the drive component 30 is connected to the connecting plate 132, and a through hole is also provided on the side connecting part 230 near the drive end of the drive component 30.

[0037] It is worth noting that the guide assembly is used to further guide the lateral movement of the whole machine. It includes a bushing 131 and a connecting plate 132. The bushing 131 is used to fit on the second guide rod, so that the lateral movement is guided and limited by the cooperation of the bushing 131 and the second guide rod, and the cooperation of the transverse channel and the first guide rod. The connecting plate 132 is used to connect the bushing 131 to the side connecting part 230, so as to ensure that the bushing 131 will not move when the three-point suspension seat 20 is fixed, thus forming the effect that only the guide rail assembly 10 drives the rotary tiller body to move relatively. After the side connecting part 230 and the connecting plate 132 are connected, in order to avoid affecting the extension and retraction of the drive end, a through hole needs to be opened on the side connecting part 230 near the drive end of the drive assembly 30 so that the drive end can extend and retract through.

[0038] In 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 protrudes from the top of the suspension, and the two side connecting parts 230 are arranged laterally opposite to each other on both sides of the bottom end of the suspension bracket 210, and the side connecting parts 230 are provided with through holes corresponding to the transverse channel.

[0039] It should be noted that the suspension bracket 210 is an integral part of the entire suspension seat, and it is convex in shape. This allows the upper connecting part 220 and the two side connecting parts 230 to connect from the top and the sides respectively, forming a triangular distribution. This connection is more stable. The top of the side connecting part 230 protrudes to the rear end to connect with the connecting plate 132 on the bushing 131. The bolt connection is convenient for disassembly and replacement. Since the side connecting parts 230 are installed on both sides of the suspension bracket 210, in order to facilitate the passage of the first guide rail 120, through holes are opened on the side connecting parts 230 that correspond to the transverse channel. Here, corresponding means that the through holes have the same size and shape as the transverse channel and are aligned with the same axis.

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

[0041] It is worth noting that using a hinged design can avoid rigid failure caused by small displacements when driving movement, which is the case with rigid connections. This can improve the structure's adaptability to offset at the connection and extend the structure's service life.

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

[0043] It should be noted that this design allows for easy assembly and disassembly when connected to an external tractor, and the connection is secure, ensuring the stability of the three-point suspension seat 20 with the tractor during lateral movement.

[0044] Furthermore, the drive assembly 30 employs a hydraulic cylinder.

[0045] It should be understood that hydraulic cylinders can provide large pressure thrust and are a commonly used drive component 30. In order to achieve push and pull back and forth in this application, a double-acting cylinder can be further adopted.

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

[0047] It should be noted that the frame 410 is used for mounting the rotary tillage assembly 420, which consists of a rotating shaft and rotary tillage blades, as is well known to those skilled in the art, and therefore will not be described in detail here. The mounting bracket 411 protrudes from the top of the frame 410, so as to facilitate the mounting 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 is vertically adjustable.

[0049] It should be noted that the limiting rod seat 412 is used to limit the vertical position and 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 limiting rod. The rod sleeve is fixedly connected to the frame 410, and the limiting rod has multiple adjustment holes arranged vertically at intervals. The rod sleeve is also provided with an adjustment hole. When the target height position is reached, the adjustment hole can be aligned with a screw or the like to limit the height adjustment. Preferably, the distance between each two adjacent adjustment holes is 25mm to 30mm. Those skilled in the art can set it according to actual needs.

[0050] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
