Description

Technical Field

[0001] The utility model relates to the technical field of micro-tillage machines, in particular to an offset micro-tillage machine frame structure and a micro-tillage machine. Background Art

[0002] Micro-tillage machines are needed in the agricultural farming process. Micro-tillage machines are small and flexible in structure and easy to use. They play a significant role in agricultural production and fruit tree planting. At present, micro-tillage machines are mainly divided into two types: hand-held micro-tillage machines and ride-on micro-tillage machines. Hand-held micro-tillage machines require personnel to hold the handrails of the micro-tillage machines with their hands, control the micro-tillage machines to move forward and follow the micro-tillage machines in the fields. The disadvantage of hand-held micro-tillage machines is that the staff need to constantly follow the micro-tillage machines in the fields. During the farming season, when the farming workload is large, the hand-held farming method is easy to cause excessive fatigue to the staff. The ride-on micro-tillage machine allows the staff to sit on the micro-tillage machine to drive the machine to move without constantly walking. Compared with the hand-held micro-tillage machine, the ride-on micro-tillage machine bids farewell to the traditional farming mode, realizes mechanization and humanization, does not require manual heavy work, and saves labor costs.

[0003] The utility model patent (authorization announcement number: CN204968358U) discloses a three-wheeled micro-tillage machine that can be ridden. The power assembly of this solution is installed at the rear end of the frame, and the gear box is installed behind the power assembly. The guide wheels, power mechanism and working parts of this solution are arranged in the front-to-back direction, resulting in a long front-to-back length of the machine. When the micro-tillage machine is working and moves horizontally to the end of the field, there is a long section of the field at the end of the field that cannot be cultivated, and the machine needs to be moved longitudinally for supplementary cultivation, or the end of the field needs to be supplemented by manual cultivation, and the farming efficiency is low. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide an offset micro-tillage machine frame structure and a micro-tillage machine. By arranging the riding parts in an offset manner, the overall length of the micro-tillage machine from front to back can be shortened, ensuring that the working parts can be as close to the edge of the field as possible. When cultivating, the length of the edge of the field that cannot be cultivated in a single pass is shortened, thereby reducing the workload of subsequent tillage.

[0005] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0007] The bottom support frame is U-shaped and a rotating shaft is arranged at the rear opening through a fixed sleeve; the front end of the rotating shaft inside the bottom support frame is used to connect the driving assembly, and the rear end of the driving assembly is used to pass through the rotating shaft to connect the working parts;

[0008] The riding component is arranged at one side of the bottom support frame, and includes a support base for installing a seat, and a sleeve for installing a handle assembly is provided at the front end of the support base; the riding component and the drive assembly are arranged in parallel, and the front end of the riding component and the front end of the drive assembly are both located in the lateral direction of the front end of the bottom support frame.

[0009] As a further implementation, the bottom support frame includes a first side and a second side connected by a connecting rod at the front end, the first side and the second side extend longitudinally and a fixing sleeve is transversely arranged at the rear end.

[0010] As a further implementation method, both ends of the rotating shaft are used to pass through the fixed sleeve and install the rear wheels, and the driving assembly is connected to the input end of the rotating shaft to drive the rotating shaft to rotate.

[0011] As a further implementation, a limiting sleeve is laterally provided at the first side edge and the second side edge near the front end position for limiting the driving assembly.

[0012] As a further implementation, a support frame is obliquely arranged on the top of the bottom support frame near the rear end.

[0013] As a further implementation, a mounting frame is provided on the second side away from the first side plate, a support seat is provided on the top of the mounting frame, and the support seat is located in the middle of the bottom support frame.

[0014] As a further implementation method, a front bracket is provided at the top of the front end of the mounting frame, and the sleeve is located at the front end of the front bracket. The sleeve is used to cooperate with the rotating shaft of the handle assembly, and the sleeve is flush with the front end of the bottom support frame.

[0015] As a further implementation, a support is provided on the top of the front end of the first side, and a counterweight is provided on the support.

[0016] As a further implementation method, the support is installed on the bottom support frame through a column, and the bottom end of the column that passes through the bottom support frame is provided with a universal wheel.

[0017] In the second aspect, an offset micro-tiller comprises an offset micro-tiller frame structure as described above, wherein a rotating shaft of a handle assembly is installed at a sleeve, and a front guide wheel is installed through the bottom end of the sleeve, and the front guide wheel is located in the lateral direction of the front end of a bottom support frame; the front end of the rotating shaft inside the bottom support frame is connected to a drive assembly, and the front end of the drive assembly extends to the front end of the bottom support frame, and both ends of the rotating shaft pass through a fixed sleeve and are installed with rear wheels, and the rear end of the drive assembly passes through the rotating shaft to connect to the working parts, and retractable pins are arranged on both sides of the front end of the drive assembly for inserting into the limiting sleeve; a seat is installed on the top of the support seat.

[0018] The beneficial effects of the above utility model are as follows:

[0019] 1. The riding component of the utility model is arranged on one side of the bottom support frame to realize an offset arrangement, and the riding component and the driving assembly are arranged in parallel, and the front end of the riding component and the front end of the driving assembly are both located in the lateral direction of the front end of the bottom support frame, thereby shortening the overall front and rear length of the micro-tillage machine (the distance from the bottom support frame to the working component), ensuring that the working component can be as close to the edge of the field as possible. When cultivating, the length of the edge of the field that cannot be cultivated in a single pass is shortened, thereby reducing the workload of subsequent supplementary cultivation.

[0020] 2. The front guide wheel of the utility model can be located in the lateral direction of the front end of the bottom support frame. The setting of the front guide wheel does not occupy the overall length of the frame. Compared with the method of setting the guide wheel in front of the frame in the prior art, during the farming process, the front guide wheel, the front end of the bottom support frame and the front end of the drive assembly of the utility model can all be moved to a position close to the edge of the field, ensuring that the working part can be as close to the edge of the field as possible.

[0021] 3. The utility model adds a supporting structure, and a counterweight can be added to the supporting structure to ensure the balance of the frame structure during the travel process. In addition, a universal wheel can be set at the bottom of the column at the bottom of the support to further ensure the balance of the frame structure during the travel process.

[0029] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0030] Embodiment 1

[0031] In a typical implementation of the present invention, reference is made to Figure 1-Figure 4 As shown, an offset micro-tillage machine frame structure includes a bottom support frame 1, which is U-shaped, with a seat component on one side, a sleeve 5 for mounting a handle assembly at the front end of the seat component, a rotating shaft 8 is arranged at the rear end opening of the bottom support frame 1 through a fixed sleeve 7, the front end of the rotating shaft 8 inside the bottom support frame 1 is used to connect the drive assembly, and the rear end of the drive assembly is used to connect the working component through the rotating shaft 8. The seat component and the drive assembly are arranged in parallel, and the front end of the seat component and the front end of the drive assembly are both located in the lateral direction of the front end of the bottom support frame 1.

[0032] By arranging the riding part on one side of the frame, and then arranging the front end of the drive assembly at the front end position of the entire bottom support frame, it is equivalent to pulling the drive assembly forward, and then pulling the working part (rotary tiller structure) forward, thereby shortening the distance between the front end of the frame structure and the working part, and shortening the overall length of the micro-tillage machine frame structure, thereby solving the problem that there is a long section of the field that cannot be cultivated at the end of the field. Through this improvement, when cultivating, the length of the field that cannot be cultivated in one way is shortened, reducing the workload of subsequent supplementary cultivation.

[0033] like Figure 1-Figure 4 As shown, the bottom support frame is U-shaped, and includes a first side 11 and a second side 12 connected by a connecting rod at the front end. The connecting rod can be a straight rod or a U-shaped rod. In this embodiment, the U-shaped rod is shorter, about 20-30 cm.

[0034] The first side 11 and the second side 12 extend in the longitudinal direction, and the rear ends of the first side 11 and the second side 12 are open ends of the bottom support frame, and the rear ends of the first side 11 and the second side 12 are transversely connected to the fixing sleeve 7. The rotating shaft is rotatably matched with the fixing sleeve 7, and both ends of the rotating shaft 8 pass through the fixing sleeve 7 and are installed with the rear wheels.

[0035] The drive assembly of this embodiment is longitudinally arranged at the front end of the rotating shaft 8 and located inside the bottom support frame 1. The drive assembly is used to provide power, and the main structure at the rear end of the drive assembly is sleeved in the middle of the rotating shaft 8. The rear end of the main structure is connected to the working component, and the working component is located at the rear side of the rotating shaft 8. The output end of the power structure inside the drive assembly cooperates with the power input structure arranged in the middle of the rotating shaft 8, so that the drive assembly drives the rotating shaft to rotate and the rear wheel rotates.

[0036] The power input structure arranged in the middle position of the rotating shaft can be a gear, and a gear box can be arranged inside the driving assembly. It should be noted that the power transmission between the driving assembly and the rotating shaft is a prior art and is not limited here.

[0037] In order to limit the front end of the driving assembly, a limiting sleeve 6 is transversely provided near the front end of the first side 11 and the second side 12 for limiting the driving assembly. A retractable pin can be provided on both sides of the driving assembly near the front end for inserting into the limiting sleeve 6 to prevent the driving assembly from rotating, so that the driving assembly as a whole is arranged along the top plane of the bottom support frame.

[0038] like Figure 1 As shown, a support frame 9 is obliquely arranged at the top of the bottom support frame 1 near the rear end. The support frame 9 is also U-shaped, and the two side edge ends of its open end are welded to the rear ends of the first side edge 11 and the second side edge 12 respectively.

[0039] When the tiller wheel sinks into the soil and is inconvenient to move forward, the support frame 9 can provide a pushing point to manually push the machine out.

[0040] like Figure 1 As shown, a mounting frame 3 is provided on the side of the second side 12 away from the first side plate 11, a support seat 2 is provided on the top of the mounting frame 3, and the support seat 2 is located in the middle of the bottom support frame 1. The mounting frame 3 of this embodiment is a frame structure, welded to the outside of the second side and arranged near the front end of the second side 12. The specific shape of the mounting frame 3 is not limited, as long as the support seat 2 can be welded on the top.

[0041] The support seat 2 is located in the middle of the bottom support frame and is arranged near the rear end of the mounting frame 3. A front bracket 4 is arranged at the top of the front end of the mounting frame 3. The front bracket 4 extends upward and forward obliquely and is provided with a sleeve 5. The arrangement of the sleeve 5 facilitates the installation of the rotating shaft of the handle assembly, and the sleeve 5 is used to cooperate with the rotating shaft of the handle assembly.

[0042] The sleeve and the front bracket 4 of this embodiment are also part of the riding component, and the sleeve is flush with the front end of the bottom support frame.

[0043] The bottom end of the rotating shaft of the handle assembly passes through the sleeve 5, and the two sides can be welded with pedals. The bottom end of the rotating shaft is installed with a front guide wheel, and the top end of the rotating shaft is vertically connected to the handle. A hand brake can be set on the handle assembly, and the structure of the hand brake is not limited and is a prior art.

[0044] like Figure 1 and Figure 2 As shown, the offset micro-tiller frame structure of this embodiment arranges the riding component on the outside of the second side 12 of the bottom support frame 1, so that the micro-tiller frame structure is an offset arrangement, and the riding component includes a support seat 2 and a front bracket 4, and a sleeve 5 distributed along the longitudinal direction of the frame structure, and the drive assembly is also distributed along the longitudinal direction, and the riding component and the drive assembly are arranged side by side.

[0045] The front end of the riding part and the front end of the drive assembly are both located in the lateral direction of the front end of the bottom support frame. By arranging the riding part on one side of the bottom support frame, compared with the prior art, the offset frame structure of this embodiment can make the front end of the drive assembly extend to the front end position of the bottom support frame 1, thereby realizing that the working part connected to the rear end of the drive assembly can be pushed forward, thereby shortening the overall front and rear length of the micro-tillage machine (the distance from the bottom support frame to the working part), and effectively solving the problem of a long section of the field that cannot be cultivated at the end of the field during cultivation. Through this improvement, the length of the field that cannot be cultivated in one direction during cultivation is shortened, thereby reducing the workload of subsequent supplementary cultivation and improving work efficiency.

[0046] The front guide wheel of this embodiment can be located in the lateral direction of the front end of the bottom support frame. The front guide wheel is set without occupying the overall length of the frame. During farming, the front guide wheel, the front end of the bottom support frame and the front end of the drive assembly can all be moved to a position close to the edge of the field, ensuring that the working part can be as close to the edge of the field as possible.

[0047] Due to the offset arrangement of the micro-tillage machine, the support seat 2 is moved to one side of the bottom support frame. When a seat is installed on the support seat 2, during work, if the worker sits on the seat and has a heavy weight, the frame structure may be eccentric. In order to solve this problem, a support is provided at the top of the front end of the first side of the embodiment, and a counterweight is provided on the support.

[0048] like Figure 3 and Figure 4 As shown, the support 14 is a plate-like structure, the bottom of which is welded to the column 13. The bottom end of the column can be welded to the front end of the first side 11, or to the left side of the U-shaped connecting rod. A counterweight, column stone, or small sandbag can be placed on the top surface of the support 14 to balance the problems caused by the above-mentioned gravity eccentricity.

[0049] In another preferred example, the support 14 is installed on the bottom support frame 1 through the column 13, and the column 13 passes through the bottom end of the bottom support frame 1 to install a universal wheel. The offset micro-tillage machine structure is changed from three wheels to four wheels. This method can also solve the problem caused by gravity deviation.

[0050] Embodiment 2

[0051] In a typical implementation of the present invention, reference is made to Figure 1-Figure 4 As shown, an offset micro-tiller includes an offset micro-tiller frame structure as in Example 1, wherein a rotating shaft of a handle assembly is installed at a sleeve 5, a front guide wheel and a foot pedal are installed through the bottom end of the sleeve 5, and a handle can be welded to the top end and a hand brake can be provided.

[0052] The front guide wheel is located in the transverse direction of the front end of the bottom support frame and is aligned with the front end of the bottom support frame 1. The front end of the rotating shaft inside the bottom support frame is connected to the drive assembly. The front end of the drive assembly extends to the front end of the bottom support frame 1. Retractable pins are set on both sides. The driving assembly is limited by the pin structure and the limit sleeve 6.

[0053] Both ends of the rotating shaft pass through the fixed sleeves and are installed with the rear wheels. The rear end of the driving assembly passes through the rotating shaft to connect the working parts. An oblong hole is provided on the supporting seat for installing a seat on the top.

[0054] By arranging the seat on one side of the bottom support frame, an offset design of the micro-tillage machine frame structure is achieved, so that the front guide wheel, the front end of the drive assembly and the front end of the bottom support frame are flush and located in the same lateral direction, so that the working parts are set forward, thereby shortening the overall front-to-back length of the frame. When tilling, the working parts can be as close to the edge of the field as possible, shortening the length of the edge of the field that cannot be tilled in one go, thereby reducing the subsequent tillage workload.

[0055] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
