Description
Technical field
The utility model is related to technical field of agricultural machinery, more particularly to a kind of pickup.
Background technology
Pickup is that stalk is picked up into a collected important process part inside field.Its operation principle is,
In the course of the work, pickup drives drive axis by power source, when power transmission shaft rotates, on axle it is some pickup teeth around
Power transmission shaft rotates, and picks up in tooth insertion stalk layer, then stalk lifting is got up, and by the rear portion of stalk horizontal sliding to pickup,
Complete to pick up operation.
The pickup tooth of tradition pickup is in the radial direction of power transmission shaft all the time at present, and the radius of gyration is larger, so that picking up
The space-consuming of device is big, picks up tooth and is easily damaged deformation, the pickup tooth after deformation can not be run according to the movement locus of design,
Have a strong impact on pickup efficiency.
Utility model content
Technical problem to be solved in the utility model and propose technical assignment be prior art is improved there is provided
A kind of pickup, the tooth of picking up for solving traditional pickup in current technology uses fixed structure, and the radial direction of power transmission shaft is in eventually,
Space-consuming is big, is easily deformed impaired, the problem of efficiency is picked up in influence.
To solve above technical problem, the technical solution of the utility model is：
A kind of pickup, including power transmission shaft, fixed disk, tooth beam and pickup tooth, it is characterised in that the two of described power transmission shaft
End be connected be connected between fixed disk, two fixed disks some along transmission shafts to tooth beam, and tooth beam is along power transmission shaft
Circumference be uniformly distributed, axially some pickup teeth of escapement on tooth beam, described tooth beam is existed by bearing arrangement
On fixed disk, and tooth beam is connected by crank with rolling member, and described rolling member slides to drive along the slideway on track plates
Tooth beam rotation.Pickup described in the utility model is rotated using rolling member and crank come sliding tooth beam, so as to change pickup tooth
Length direction so that pick up tooth can stretch out and withdraw, power transmission shaft radially and tangentially between change, by ground
The radial direction that tooth is in power transmission shaft is picked up when stalk is provoked, that is, picks up tooth and is in stretching state, it is ensured that can be effectively by stalk
Lifting is got up, and is shifted onto by stalk after the rear of pickup, and rolling member and crank carry out sliding tooth beam rotation so that pick up teeth directional
The tangential rotation of power transmission shaft is radially reclaimed, and is reduced revolution volume, is occupied little space, and avoids pickup tooth from shifting onto after pickup
The stalk of side is taken out of again, ensures the efficiency picked up.
Further, described tooth beam is by bearing with spherical outside surface device in fixed disk, and bearing with spherical outside surface can be incorporated bearing
Play a part of aligning in the corresponding concave spherical surface of seat, the radial direction and axial joint load based on radial load can be born, no
It is yielding, make pickup transmission more reliable and more stable.
Further, described rolling member uses bolt outer ring and roll assembly, and stress is more stablized, and service life is long, makes
With security reliability, it is convenient to assemble and disassemble.
Further, described pickup tooth uses torsion spring structure, can play a part of buffering, is imitated with adaptive avoidance
Really, it is to avoid condition of work badly causes to pick up tooth deformed damaged, and service life is long.
Further, be provided with the circumference of power transmission shaft by institute's beam with teeth be enclosed in backplate, and described shield
Axially spaced-apart of the plate along power transmission shaft is set, and is picked up tooth along the gap spinning movement between backplate, is played the effect of being effectively protected, keep away
Exempt from power transmission shaft and tooth beam to be blocked by the winding of stalk, be driven more reliable and more stable, reduction abrasion, ensure service life.
Compared with prior art, the utility model advantage is：
Picker structure described in the utility model is simply compact, turns round volume, occupies little space, and stable transmission is reliable,
The efficiency picked up is ensured, not easily damaged, service life is long, and cost easy to maintenance is low.

Fig. 2 is Fig. 1 partial structural diagram；
Fig. 3 is the structural representation of track plates.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Pickup disclosed in the utility model embodiment, compact conformation picks up the action that tooth can be stretched out and be withdrawn, work
Occupy little space, be hardly damaged, ensure and pick up efficiency.
As shown in Figure 1 to Figure 3, a kind of pickup, including power transmission shaft 1, fixed disk 2, tooth beam 3, pickup tooth 4 and backplate 8, are passed
The two ends of moving axis 1 are connected with and some tooth beams 3 along the axial direction of power transmission shaft 1 are connected between fixed disk 2, two fixed disks 2, and
Circumference of the tooth beam 3 along power transmission shaft 1 is uniformly distributed, and drives fixed disk 2 to rotate when power transmission shaft 1 is rotated, week of the tooth beam 3 along power transmission shaft 1
To rotation, along some pickup teeth 4 of axially spaced-apart device of power transmission shaft 1 on tooth beam 3, pick up tooth 4 and use torsion spring structure, shield
In plate 8 is arranged in the circumference of power transmission shaft 1 and is enclosed in institute's beam 3 with teeth, backplate 8 maintains static dynamic, and backplate 8 is along power transmission shaft
1 axially spaced-apart is provided with several, is driven when power transmission shaft 1 is rotated and picks up tooth 4 along the gap spinning movement between backplate 8.
In the present embodiment, tooth beam 3 sets thickening type by bearing with spherical outside surface device on fixed disk 2 on fixed disk 2
