Description
Technical Field
The invention belongs to the technical field of agricultural machinery, and particularly relates to a micro-cultivator cutter holder bearing support rod.
Background
The mini-tiller uses a small diesel engine or a gasoline engine as power, and has the characteristics of light weight, small volume, simple structure and the like. The mini-tiller is widely applicable to dry lands, paddy fields, orchards and the like in plain, mountain areas and hills. The micro-cultivator can be matched with a corresponding machine tool to carry out operations such as water pumping, power generation, pesticide spraying, spraying and the like, and can also pull a trailer to carry out short-distance transportation, so that the micro-cultivator can be freely used in fields, is convenient for users to use and store, eliminates the trouble that large farm machinery cannot enter mountain areas, and is the best choice for vast farmers to replace cattle cultivation.
The existing mini-tiller can adjust the inclination angle of a tillage knife and the advancing distance on a shaft. In order to achieve such adjustment, a bearing support rod is designed to act on the tillage cutter according to the structural characteristics of the machine body, so as to help the adjustment and the stabilization at the required position.
Disclosure of Invention
In view of the above-mentioned drawbacks of the prior art, the present invention is to provide a force-bearing support rod for a tool apron of a mini-tiller.
The technical scheme is that the force bearing support rod of the micro-cultivator tool apron comprises a front column, wherein the front end of the front column is provided with a support head, the support head is in a taper shape with a small front and a big rear, a middle column is arranged behind the front column, the front column and the middle column are connected into a whole through a connecting rod, the connecting rod is coaxially arranged with the middle column and the front column, the diameter of the connecting rod is smaller than that of the middle column and the front column, a first spring and a second spring are sleeved on the connecting rod, the positions of the first spring and the second spring are opposite, the front end of the first spring is fixedly connected onto the rear end face of the front column, the rear end of the second spring is fixedly connected onto the front end face of the middle column, the rear end of the first spring and the front end of the second spring are suspended, a rear column is arranged behind the middle column, the rear column is thin front and thick rear and is transited through a taper surface, the rear column and the middle column are integrally connected through a rear sleeve shaft, and the rear sleeve shaft and the rear sleeve are coaxially arranged with the middle column.
Further, the front end of the abutment forms a plane.
Further, a secondary step post with thick front and thin rear is arranged at the center of the rear end face of the front post, and the connecting rod is connected to the secondary step post.
Further, the middle column is in a secondary step shape with thin front and thick rear.
The beneficial effects are that: the invention has reasonable design, simple structure and convenient use, and the angle and the axial direction of the tillage knife can be adjusted as much as possible by being matched with the machine body and abutting against the tillage knife, so that the effect is good.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Detailed Description
The invention is further illustrated by the following examples in conjunction with the accompanying drawings:
the utility model provides a machine blade holder bearing support pole that ploughs a little, shown in figure 1 has preceding post 1, the front end of preceding post 1 is provided with supports head 2, it is big taper in front and back to support head 2, preceding post 1 rear is provided with center pillar 3, just connect as an organic wholely through connecting rod 4 between preceding post 1 and the center pillar 3, connecting rod 4 with center pillar 3 and preceding post 1 coaxial setting, the diameter of connecting rod 4 is less than center pillar 3 and preceding post 1's diameter, the cover is equipped with first spring 5 and second spring 6 on the connecting rod 4, first spring 5 and second spring 6 position are relative, the front end fixed connection of first spring 5 is in on the rear end face of preceding post 1, the rear end fixed connection of second spring 6 is in on the front end face of center pillar 3, the rear end of first spring 5 and the front end of second spring 6 all hang in midair, the rear of center pillar 3 is provided with rear post 7, rear 7 just through thick and back 7 and through the rear sleeve of post 7 and coaxial coupling post 8 between rear cone and the rear sleeve 3 and the coaxial post 8. As a preferred structural form, the front end of the abutment 2 forms a plane. A secondary step post 9 with thick front and thin rear is arranged at the center of the rear end face of the front post 1, and the connecting rod 4 is connected to the secondary step post 9. The middle column 3 is in a secondary step shape with thin front and thick rear.
The principle of the invention is as follows:
the front column 1 and the abutting head 2 are connected into a whole, the abutting head 2 directly abuts against the tillage cutter, the reaction force enters the front column 1 through the abutting head 2, and the front column 1 is directly a bearing part, so that the whole bearing force is relatively uniform. The middle column 3 and the front column 1 form a structure with thick two ends and thin middle part, and the middle part is the connecting rod 4. In actual installation and use, the connecting rod 4 is a part for clamping on equipment and can rotate. And also cooperates with the first spring 5 and the second spring 6 to produce axial movement adjustment. Similarly, the thinner structure formed by the rear sleeve shaft 8 between the center pillar 3 and the rear pillar 7 is also used to connect with the structure on the fuselage to form a rotatable structure. The front end of the abutting head 2 is arranged to be a plane, so that stable contact with the tillage cutter surface is facilitated. The rear end of the front column 1 is provided with a second-stage step column 9 which is used for being matched with a connecting structure on a machine body to form a staggered contact structure implementation, so that the connection is more stable. The secondary stepped structure of the center pillar 3 is more convenient for manual adjustment.
The foregoing describes in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be made in accordance with the concepts of the invention by one of ordinary skill in the art without undue burden. Therefore, all technical solutions which can be obtained by logic analysis, reasoning or limited experiments based on the prior art by the person skilled in the art according to the inventive concept shall be within the scope of protection defined by the claims.
