Description
Technical field
This utility model is related to technical field of chain transmission, more particularly, to a kind of chain stretching device.
Background technology
Adjustment along with China's land policy and the raising of agricultural modernization degree, large-scale agricultural machinery has obtained extensively
Popularization.Can preferably work under low-speed heave-load because Chain conveyer has, adapt to severe working environment, manufacturing cost is relatively
Low a series of advantage, is therefore widely used in agricultural machinery product.However, Chain conveyer exists when using one section
Between back pitch become big, easily cause the phenomenon coming off.
The tensioning wheel of traditional structure is mostly fixed sprocket wheel or nylon wheel construction, makes to be bolted to during assembling
On elongated hole, due to the shake of chain during using, easily produce bolt looseness phenomenon.User's maintenance number of times is frequent, machine
Handss complaint is larger, the tensioning of the simultaneously fixed drive mechanism that may not apply to tend to vertical stratification arrangement, and range is limited to
Property is big.In addition traditional structure elastic tension structure is all using single nylon wheel tensioning, can only carry out a tensioning to chain,
Tight stroke is little, and whole machine arrangement space demand is big, difficult arrangement.
Utility model content
Technical problem to be solved in the utility model is：There is provided a kind of chain stretching device, this device can effectively solving
Agricultural Machinery Design chain need to frequently adjust the problem of tension structure, and this device is applied to and is limited by space and tend to vertical stratification
The chain drive structure of arrangement, this device can automatic adjustment spring pretightning force, improve the whole aircraft reliability of agricultural machinery product and minimizing
The maintenance time.
For solving above-mentioned technical problem, the technical solution of the utility model is：A kind of chain stretching device, including tensioning
Seat, two ends of described backstand are rotatablely equipped with the first tensioning wheel and the second tensioning wheel respectively, described backstand and one
Support member is hinged；Tensioning spring is arranged between described backstand and another support member.
As a kind of improved mode, described backstand is diamond-type base.
As a kind of improved mode, described tensioning spring is extension spring, described extension spring be mounted on described backstand with described
Between another support member.
As a kind of improved mode, also include adjusting screw rod, described adjusting screw rod one end is mounted with described extension spring, another
Hold the installing hole through described another support member rotation set nut.
As a kind of improved mode, described first tensioning wheel and the second tensioning wheel all with bolt as pivot, described pivot
Sheathed pipe, described first tensioning wheel and and the second tensioning wheel be sheathed on respectively described between manage.
As a kind of improved mode, described pivot is arranged with inner washer and outer washer, the end of thread of described pivot
Portion's rotation set nut will be described between tube grip between described inner washer and described outer washer.
Using the technique effect acquired by technique scheme it is：
Using limited space, the slack list of chain can be carried out with secondary tensioning using two tensioning wheels, increase stroke of tension.
Elastic tension structure, constantly release and update the system tensile force, absorb vibratory impulse, increase chain service life, reduce machine handss
Maintenance and service time.This tensioner tends to vertically arranged Chain conveyer for space-constrained and provides effective tensioning
Scheme.The motility of whole machine arrangement can be greatly improved using this tensioner, increase the stationarity of transmission, improve whole machine reliable
Property, greatly increase the mean free error time of power train, reduce user's labor intensity, bring bigger economic well-being of workers and staff to user.
Because described backstand is diamond-type base, limited installing space can be made full use of.
Due to also including adjusting screw rod, described adjusting screw rod one end is mounted with described extension spring, and the other end passes through described another
The installing hole of support member rotation set nut, by the rate of tension of adjusting screw rod adjusting tensioning spring.

Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with Figure of description
And embodiment, this utility model is further elaborated it will be appreciated that specific embodiment described herein only in order to
Explain this utility model, be not used to limit this utility model.
Jointly shown in conjunction with Fig. 1 and Fig. 2, a kind of chain stretching device, including backstand 1, in the present embodiment, backstand 1
For diamond-type base, to reduce installing space.Two ends of backstand 1 are rotatablely equipped with the first tensioning wheel 21 of nylon material respectively
With the second tensioning wheel 22, the first tensioning wheel 21 and the second tensioning wheel 22 all with bolt 11 as pivot, between two pivots are all arranged with
Pipe 10, the first tensioning wheel 21 and and the second tensioning wheel 22 be sheathed on a pipe 10 respectively.
Pivot is arranged with inner washer 13 and outer washer 14, and between the thread head rotation set nut of pivot is incited somebody to action, pipe 10 is clamped in
Between inner washer 13 and outer washer 14.Backstand 1 is hinged with a support member 5, tensioning spring be arranged at backstand 1 with another
Between support member 4.In the present embodiment, tensioning spring selects extension spring 3, and extension spring 3 is hung one end and is mounted on backstand 1, the other end and tune
Section screw rod 9 connects, and the other end of adjusting screw rod 9 is provided with screw thread and passes through installing hole the rotation set nut of another support member 4.
Operation principle of the present utility model is as follows：
Backstand 1 is articulated with support member 5, and another support member 4 is fixed on by nut in adjusting screw rod 9 lower end.In big sprocket wheel 6
Upper, minor sprocket 7 under, on the right side of driving chain be chain slack list 8 in the state of.It is right that first tensioning wheel 21 is located at chain slack list 8
Side, the second tensioning wheel 22 is located on the left of chain slack list 8.First tensioning wheel 21 and two nylon tensioning wheel fortune of the second tensioning wheel 22
The dynamic chain slack list 8 to driving chain in opposite direction applies tensile force, according to being arranged so as to increase the cornerite of big sprocket wheel 6,
And increase stroke of tension.
In assembling process, the coplanar of chain drive face can be adjusted by adjusting inner washer 13 or outer washer 14
Degree；Adjust the size of the initial pretightning force of sequence extension spring 3 by adjusting adjusting screw rod 9 screw thread exposed length L-value.
When the position of large and small sprocket wheel is to timing, the rigging position of the first tensioning wheel 21 and the second tensioning wheel 22 and motion side
To also need accordingly to change it is ensured that reach in limited space maximum stroke of tension.
After suitable backstand rotation fulcrum and adjusting screw rod 9 lower end mounting point are reasonably searched out on machine, profit
Effectively secondary tensioning can be carried out with this device to tending to vertically arranged drive mechanism, stroke of tension is big, takes up room little.
The extension spring 3 of adjusting screw rod 9 upper end can effectively buffer and absorb vibratory impulse, constantly discharge tensioning pressure, persistently to chain simultaneously
Bar carries out tensioning, reduces the maintenance of machine handss and repeatedly debugs number of times.
Above example be this utility model preferred embodiment, not in order to limit this utility model, every in this reality
Within new spirit and principle, any modification, equivalent substitution and improvement made etc., should be included in of the present utility model
In protection domain.
