Abstract
The utility model discloses a mini-tiller tensioning wheel mounting structure. A tensioning wheel is arranged on a power supporting frame of a mini-tiller, a vertical arm is arranged on the power supporting frame, a rotary shaft is arranged at the upper end of the vertical arm, a rotatable connecting block is arranged on the rotary shaft, and the tensioning wheel is rotatably arranged on the rotary shaft through the connecting block. The rotary shaft is sleeved with a tensioning torsional spring, one end of the tensioning torsional spring is arranged on the connecting block, and downward acting force is exerted on the tensioning wheel through the connecting block. An inhaul cable spring is arranged to be connected on the connecting block, and acting force of the inhaul cable spring on the connecting block is opposite to the acting force of the tensioning torsional spring on the connecting block. The mini-tiller tensioning wheel mounting structure is provided with the springs in the two directions, the situation that a belt is overloaded due to the fact that the displacement of the tensioning wheel is too large can be avoided, and the tensioning wheel can be reset fast. In addition, the mini-tiller tensioning wheel mounting structure has the advantage of being fast and flexible in movement.
Description
Technical field
The utility model relates to a kind of microtilling machine bel-drivenn Idle wheel, particularly microtilling machine Idle wheel mounting structure.
Background technique
Along with the development of China's agricultural modernization, microtilling machine has entered into a lot of peasant families, and microtilling machine can alleviate peasant's labor intensity, raise labour productivity etc.
The power transmission of microtilling machine has a variety of structures, and belt transmission is a kind of common structure, and it is, between driving pulley, driven pulley, drivign belt is set, driving pulley through drivign belt drive driven pulley rotate, thereby by transmission of power to driven pulley.Between driving pulley, driven pulley, need to arrange Idle wheel, in the time that Idle wheel rotates, promote belt with tightening belt (tightening belt), prevent that it from skidding, and can reduce the loss of moment of torsion in belt transport process.The Idle wheel of prior art, the main deficiency of its existence is as follows: at operator's handle with sleeve to rotate when Idle wheel, can not control accurately the position of Idle wheel, Idle wheel is difficult to accurate control to the promotion amount of belt, the displacement amount that causes Idle wheel to rotate is excessive, make belt form overload, belt is caused to larger wearing and tearing; Or the displacement amount that Idle wheel rotates is too small, the rate of tension of belt does not reach preferable states, and moment of torsion loss in belt transport process is larger.
Model utility content
The purpose of this utility model is in order to solve above-mentioned the deficiencies in the prior art, provides a kind of and can accurately control the displacement amount of Idle wheel rotation so that the rate of tension of belt reaches the microtilling machine Idle wheel mounting structure of loss of torque in preferable states, reduction belt transport process.
To achieve these goals, the microtilling machine Idle wheel mounting structure that the utility model is designed, comprise Idle wheel, described Idle wheel is arranged on the power supporter of microtilling machine, it is characterized in that, on power supporter, be provided with perpendicular arm, be provided with rotating shaft in the upper end of perpendicular arm, in rotating shaft, be provided with rotating contiguous block, Idle wheel is arranged in rotating shaft turnably by contiguous block; In rotating shaft, be arranged with tensioning torsion spring, one end of tensioning torsion spring is arranged on contiguous block, by contiguous block to downward active force of Idle wheel; Be provided with drag-line spring and be connected on contiguous block, drag-line spring and tensioning torsion spring are reverse to the active force of contiguous block.
Further feature is, carbine is set on contiguous block, and one end of drag-line spring is connected on carbine, and the other end is connected on the control drag-line of Idle wheel.
The microtilling machine Idle wheel mounting structure that the utility model obtains, is provided with the spring of both direction, and the displacement amount that can prevent Idle wheel is crossed ambassador's belt and formed overload, can make again the rapid return of Idle wheel; And, also have advantages of be swift in motion, sensitive.
Accompanying drawing explanation
Fig. 1 is that the utility model microtilling machine Idle wheel is installed perspective view;
Fig. 2 is opposite side perspective view.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
The microtilling machine Idle wheel mounting structure that the present embodiment provides, as Fig. 1, shown in Fig. 2, comprise Idle wheel 1, described Idle wheel 1 is arranged on Mini-tiller power supporting frame 2, on power supporter 2, be provided with perpendicular arm 3, upper end at perpendicular arm 3 is provided with rotating shaft 4, in rotating shaft 4, be provided with turnably contiguous block 5, Idle wheel 1 is arranged on contiguous block 5, Idle wheel 1 is arranged in rotating shaft 4 turnably by contiguous block 5, in rotating shaft 4, be arranged with tensioning torsion spring 6, one end of tensioning torsion spring 6 arranges (pressure) on contiguous block 5, give 1 one downward active forces of Idle wheel by contiguous block 5, be provided with drag-line spring 7 and be connected on contiguous block 5, drag-line spring 7 gives the active force of contiguous block 5 reverse with tensioning torsion spring 6, is contrary, be tensioning torsion spring 6 by contiguous block 5 to 1 one downward active forces of Idle wheel, drag-line spring 7 is given 1 one of Idle wheels active force upwards by contiguous block 5, shown in figure, carbine 8 is set on contiguous block 5, one end of drag-line spring 7 is connected on carbine 8, and the other end is connected on the control drag-line 10 of Idle wheel 1, controls (not shown in FIG.) on the control handle that the other end of drag-line 10 is connected to Idle wheel 1 again, in the time that operator need to rotate Idle wheel 1, rotate and control handle to pull control drag-line 10, control drag-line 10 and pull Idle wheel 1 to rotate around rotating shaft 4, after Idle wheel 1 rotates, contact and promote belt tension with belt, make belt drive follower to rotate, by belt transport power.In needs belt slack not when transferring power, unclamp and control drag-line 10 and make drag-line spring 7 lax,, under the opposition of tensioning torsion spring 6, Idle wheel 1 reverses rapidly, disengages with belt.The torsion (elastic force) that designs tensioning torsion spring 6 and drag-line spring 7 just can be controlled the maximum rotation angle (displacement) of Idle wheel 1, and the displacement amount that enables to prevent Idle wheel is crossed ambassador's belt and formed overload, can make again the rapid return of Idle wheel.Drag-line spring 7 also has buffer function, even if excessive pulling force acts on drag-line spring 7 by controlling drag-line 10, it acts on the rotation displacement causing on contiguous block 5 is also controlled, avoids the displacement amount of Idle wheel to cross ambassador's belt formation overload.
Finally it should be noted that, above embodiment is only in order to the technical solution of the utility model to be described but not restriction technologies scheme, although claimant has been described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or are equal to replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of claim scope of the present utility model.
