Abstract
The utility model provides a tillage implement pulling and hanging support which is composed of a machine frame, a bearing wheel and a lifting arm. The lifting arm is installed on the machine frame and can rotate relative to the machine frame, hanging nodes for controlling a tillage implement to ascend and descend are arranged on the lifting arm, and a limiting device is arranged for controlling the lowest positions of movement of the hanging nodes; a pulling and hanging pin shaft hole is formed in front of the machine frame, and the two sides of the back of the machine frame are provided with hanging holes or hanging pin shafts for hanging the tillage implement; the limiting device controls the maximum elongation amount of an oil cylinder or an air cylinder. The tillage implement pulling and hanging support has the advantages that the aim that the tillage implement is hung on a disc-type tractor to conduct field operation is achieved; in addition, the tillage implement is not connected with the tractor any more, and a user can easily disassemble the machine frame to hang other implements for operation; the maximum operation depth for limiting the tillage implement can be selected by the limiting device according to needs, and damage, caused by excessive operation implement descending caused by improper operation of operators, to the machine is avoided. The tillage implement pulling and hanging support is particularly suitable for being matched with the existing disc-type tractor.
Description
Technical field
The utility model relates to agricultural machinery farm work facility.
Background technology
At present, in south, there is a kind of use small tractor widely, be commonly called as disk type tractor.This tractor is developed by original hand tractor, must hang up and drag case or tail wheel while travelling, and it turns to is to rely on the realization of bowing.The short-distance transport of this used with tractor in rural area welcome by peasant very, but will carry out farm work, must supportingly can hang the frame of pulling of tillage implement.
Summary of the invention
The utility model provides a kind of tillage implement to pull frame, to address the above problem.The technical scheme of taking is: tillage implement is pulled frame and is comprised of frame, bogie wheel, lifting arm.The lifting arm one end of installing in frame is hinged in frame, can rotate relative to frame, and the other end is the hanging node of controlling tillage implement lifting., and be provided with stopping means, control the extreme lower position of hanging node motion, frame the place ahead is provided with pins axis hole, for being connected with tractor, both sides, frame rear are provided with the mount hole articulating for tillage implement or articulate bearing pin, and each side has a plurality of mount holes or articulates bearing pin, can be according to hanging the selection that needs of ploughing facility, the mount hole on these both sides or articulate bearing pin and lifting arm on hanging node form trifilar suspension, for articulating tillage implement, lifting arm adopts the flexible of oil cylinder or cylinder or waves and control hanging node motion, stopping means is comprised of two of front and back gag lever post and bearing pin, one end of two bars connects with bearing pin, can relatively rotate, the other end is connected to respectively the two ends of oil cylinder or cylinder with bearing pin, two gag lever posts are provided with the connecting hole of a plurality of available insertion bearing pins, by selecting different connecting holes, change the effective length of its bar: thus the maximal tensility of control lifting arm, realize spacing control, that is: when front and back two gag lever posts are point-blank time, it is exactly the maximum extension elongation of oil cylinder or cylinder, when oil cylinder or cylinder shortening, just form triangle with another two gag lever posts, not limiting lifting arm shortens.The advantage of this technical scheme is: solved well disk type tractor and hung the problem that tillage implement carries out farm work, and tillage implement is no longer connected with tractor, user is easy to by unloading lower bearing bracket, articulate other apparatus operation, as hung up, drag railway carriage or compartment to carry out short-distance transport; The maximum operation degree of depth that stopping means can select limit to put tillage implement as required, operator can, because of misoperation, not cause work tool to decline and excessively damage machine.
Accompanying drawing explanation
Fig. 1 is that the utility model master looks schematic diagram;
Fig. 2 is the utility model schematic top plan view;
Fig. 3 is the schematic diagram of the limited device of the hanging node of the utility model lifting arm while being limited to extreme lower position.
Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, the both sides of frame (2) are provided with bogie wheel (1), lifting arm (5) adopts hydraulic jack, one end is hinged in frame (2) with bearing pin, lifting arm (5) two ends are hinged front limit bar (4) and rear gag lever post (7) respectively, two bearing pins for gag lever post (6) are hinged, and front limit bar (4), rear gag lever post (7) form triangle stopping means with lifting arm (5), that is: the maximum extension elongation of oil cylinder is subject to the restriction of two gag lever post length sums; In lifting arm (5) and the hinged place of rear gag lever post (7), be provided with hanging node (8), frame (2) rear side is provided with mount hole (9), and hanging node (8) and mount hole (9) form trifilar suspension, for articulating tillage implement; Frame the place ahead is provided with pins axis hole (3), for being connected with tractor.
Claims (3)
1. a tillage implement is pulled frame, it is characterized in that: by frame, bogie wheel, lifting arm forms, the lifting arm one end of installing in frame is hinged in frame, can rotate relative to frame, the other end is the hanging node of controlling tillage implement lifting., and be provided with stopping means, stopping means is comprised of two of front and back gag lever post and bearing pin, one end of two gag lever posts connects with bearing pin, can relatively rotate, the other end is connected to respectively the two ends of oil cylinder or cylinder with bearing pin, two gag lever posts are provided with the connecting hole of a plurality of available insertion bearing pins, by selecting different connecting holes, change the effective length of its bar, control the maximal tensility of oil cylinder or cylinder, thereby control the extreme lower position of hanging node motion.
2. a kind of tillage implement according to claim 1 is pulled frame, it is characterized in that: frame the place ahead is provided with pins axis hole, and both sides, frame rear are provided with the mount hole articulating for tillage implement or articulate bearing pin.
3. a kind of tillage implement according to claim 1 is pulled frame, it is characterized in that: lifting arm adopts the flexible of oil cylinder or cylinder or waves and control hanging node motion.
