Abstract
The utility model relates to a tension control device for an agricultural machinery power transmission belt of an agricultural tricycle. The tension control device comprises a carriage chassis, a belt and a tension device. A tensioning wheel is mounted at one end of a tension arm; the tension arm is fixed in the center through a shaft and can rotate; a bracing wire is arranged at the other end of the tension arm; a torsion spring is mounted on the shaft; the force of the torsion spring can enable the tensioning wheel to completely separate from contacting the belt so as to cause the belt to fully relax; the bracing wire passes through the carriage chassis and is connected with a handle arranged in a marginal position below the carriage chassis; and when the handle is pulled, the bracing wire causes the tension arm to overcome the force of the torsion spring and rotate, and the tensioning wheel tightly compresses the belt. The utility model integrates the devices of strap tension, power on-off and control, thereby tensioning the belt and ensuring power transmission as well as controlling the transmission power on or off; and the tension control device completely substitutes for clutches and has the advantages of simple structure and low cost.
Description
Technical field
The utility model relates to the drag-line operating control, particularly uses the slack-free operating control of agricultural machinery power driving belt, the power-transfer clutch effect of the tensioning starting power transmission of belt on agricultural tricycle.
Background technology
Characteristics such as agricultural tricycle is strong with hill climbing ability, load carrying ability big, low consumption, low expense are subjected to rural subscribers' favor deeply, make it be widely used in the rural area.Agricultural tricycle mainly by vehicle frame, be installed in the railway carriage on the vehicle frame and the engine installation and the power drive that are installed on the vehicle frame are formed.As the driving engine of engine installation and as power-transfer clutch, the change speed gear box of power drive generally is the front portion that is positioned at railway carriage, engine crankshaft is vertically arranged along agricultural tricycle, the power of its output to diff, drives the left and right sides trailing wheel of agricultural tricycle by power-transfer clutch, change speed gear box, transmission shaft again by left and right sides two-semiaxle.At present, the functions of use of agricultural tricycle is single, only limits to as transportation means.
Need use a large amount of power machines in the rural area, as hay cutter, thresing machine, water pump, vehicle-mounted sprayer etc., these power machines need to drive as power take-off implements such as electrical motor, general gasoline engines.At present because the economic level in China rural area is limited, if use these power machines mate simultaneously provides power for it power take-off implement, then the user will pay the acquisition expenses of higher power take-off implement, thereby to a certain degree limit being extensive use of of power machine.If the power of agricultural tricycle can be used, with replace electrical motor, general gasoline engines etc. as with the supporting power take-off implement of power machine (being agricultural machinery), and utilize the usage platform of Platform for tricycle as agricultural machinery, will effect that the use of power machine is brought great convenience.
Utilize the usage platform of Platform for tricycle as agricultural machinery, need give agricultural machinery with the transmission of power of driving engine, driving engine generally can not be arranged in above the compartment, otherwise influence the basic transportation function of three-wheel vehicle, therefore, power transmission must have transmission distance very far away, the belt-driving of prior art or chain-driving all are fit to the power transmission of this distance, above-mentioned two kinds of type of drive generally all will be provided with tightening device, to prevent that belt or chain are lax, relax and to influence powerdriven efficient, serious meeting can't transferring power, even damage machine, Platform for tricycle is as the usage platform of agricultural machinery, also need to take into account at least walking and two kinds of mode of operations of agricultural machinery work, moving or motionless general employing power-transfer clutch on transmission direction of existing techniques in realizing, automobile for example, three-wheel vehicle walking power transmission of the present invention all is this method, power-transfer clutch also will be provided with operating control, to satisfy the control needs, prior art is provided with tightening device, the mode of power-transfer clutch and clutch operating device is very many, but these will use its structure more complicated simultaneously on agricultural three-wheel, cost can be higher, thereby have to a certain degree limited use.
The utility model content
The purpose of this utility model provides a kind of agricultural tricycle agricultural machinery power driving belt tensioning operating control, solution utilizes the above-mentioned technical barrier of Platform for tricycle as workplatform, utilize the tightening device of belt, finish the function of power-transfer clutch and clutch operating device, thereby the omission power-transfer clutch, cost-cutting.
Agricultural tricycle agricultural machinery power driving belt tensioning operating control described in the utility model, comprise cabin floor, belt and tightening device, the tension wheel of its tightening device is installed in tensioner arm one end, tensioner arm central authorities also can rotate with axle is fixing, there is drag-line in tensioner arm other end system, on the axle torsion spring is installed, torsion spring power can make tension wheel break away from fully to contact with belt and make belt lax fully, drag-line passes through cabin floor and is arranged on the cabin floor below, the handle of boundary position connects, when the pulling handle, drag-line makes tensioner arm overcome torsion spring power and rotates, and tension wheel compresses belt.
Belt transmission is designed to carry out tensioning without tension wheel, belt just is in relaxed state fully, can not transferring power, this state tensioner arm turning cylinder is installed a torsion spring and is realized, in the absence of other external force, torsion spring power drives tensioner arm and rotates, tension wheel rotates with tensioner arm, tension wheel is broken away from fully with belt contact, allow the complete relaxed state of belt, be equivalent to the power-transfer clutch disengaged position; When operating personal pulling handle, just spur drag-line, drag-line makes tensioner arm overcome torsion spring power and rotates, tension wheel rotates with tensioner arm, contacts with belt gradually, compresses belt up to tension wheel, the belt in tension, power can transmit, and is equivalent to the clutches engaged state.Belt tension, operating control had both played tightening belt, guaranteed the effect of power transmission efficiency, played control transferring power clutch whether effect again, had replaced power-transfer clutch fully.
The handle of manipulating pulling cable is arranged on the cabin floor below, and at the cabin floor boundary position, be because of the power clutch does not here need to resemble frequent carrying out the vehicle to run, only when using agricultural machinery, just be necessary to allow power connect, at this moment, in most cases three-wheel vehicle has stopped, the pulling process handle of getting off, at ordinary times, belt transmission is for the state that breaks away from transmission of power fully, it was both convenient to be provided with like this, can not keep off thing again.
The utility model is integrated belt tension, power clutch, operating control, has both played tightening belt, guarantees the effect of power transmission efficiency, play control transferring power clutch whether effect again, replaced power-transfer clutch fully, structure is very simple, thereby with low cost.
