Description

Dual-purpose rake of careless membrane convenient to adjust width

Technical Field

The utility model belongs to the technical field of elastic tooth type raking machines, and particularly relates to a grass and film dual-purpose raking machine convenient for adjusting the width.

Background

In modern agricultural production activities, automation equipment is applied more and more widely, and during the use of the automation equipment, straws of corn, rice and wheat are usually crushed, so that straw bundling operation in traditional agricultural activities cannot be realized, and the rakes are required to collect the straws; in the production of pasture such as alfalfa, mexican corn grass and the like, the pasture is generally cut down by using an automatic machine and then collected by using a rake; when the waste agricultural film is recycled, the rakes are usually used for raking and collecting the straws and the waste mulching films in the field; in agricultural production, due to different field sizes and different crop types, the actual widths are different, and the widths of the stacked straws and mulching films are different, so that the rakes are required to be capable of conveniently adjusting the widths to increase the adaptability, most of the rakes or mulching film collecting devices with adjustable widths are huge in size and can be driven by large-scale tractor equipment, and the use cost is undoubtedly increased; therefore, a spring tooth type grass and film dual-purpose rake machine which can adjust the breadth and cannot cause missing of straws and mulching films needs to be researched and developed.

SUMMERY OF THE UTILITY MODEL

Aiming at the technical problems, the utility model aims to provide a spring-tooth type grass and mulching film dual-purpose rake capable of adjusting the width and avoiding missing straws and mulching films.

In order to solve the technical problems, the technical scheme of the utility model is as follows: the utility model provides a dual-purpose rake of careless membrane convenient to adjust width, includes the traction frame and bears the frame, the traction frame set up in bear the frame front portion, still include the bearing plate, play tooth-like rake and supplementary rake, it is provided with to bear rear portion bilateral symmetry the bearing plate, the bearing plate front end is rotated and is provided with hand handle cover, hand handle cover lower extreme fixedly connected with gear, play tooth-like rake through receive the carrier plate with bearing plate sliding connection, receive the carrier plate front end fixed be provided with the driven rack of gear engagement, supplementary rake rotate set up in bear on the frame.

Furthermore, a limiting ring is arranged at the joint of the auxiliary rake and the bearing frame.

Further, the hand-operated handle sleeve is connected with the bearing plate through a connecting plate.

Furthermore, a limiting rod is arranged on the traction frame and is clamped with the auxiliary rake.

Compared with the prior art, the utility model has the following advantages:

the gear-rack transmission mode is utilized to drive the elastic tooth type rake to move, so that the purpose of adjusting the width is achieved, and the adaptability of the rake is improved; when the separation distance of the elastic tooth type rakes on the two sides is too large, the auxiliary rakes are put down, so that the omission of straws and mulching films is avoided, and the raking efficiency is improved; the hand crank sleeve can be used in cooperation with a crank of a tractor, so that an additional tool is not needed, and the width of the rake can be conveniently adjusted in the using process; utilize the gag lever post to carry out the joint to supplementary rake, avoid supplementary rake to fall suddenly when lifting up, produce the potential safety hazard.

Detailed Description

The utility model will be further explained with reference to the drawings.

As shown in fig. 1, fig. 2, fig. 3, the dual-purpose rake of careless membrane convenient to adjust width, including traction frame 1 and carrier frame 2, traction frame 1 sets up in carrier frame 2 front portion, still include bearing plate 3, play tooth-like rake 4 and supplementary rake 5, carrier frame 2 rear portion bilateral symmetry is provided with bearing plate 3, bearing plate 3 front end rotates and is provided with hand handle cover 31, hand handle cover 31 lower extreme fixedly connected with gear 32, play tooth-like rake 4 is including receiving carrier plate 41 and rack 42, play tooth-like rake 4 is through receiving carrier plate 41 and bearing plate 3 sliding connection, receive carrier plate 41 front end fixed be provided with gear 32 meshing driven rack 42, supplementary rake 5 rotates and sets up on carrier frame 2.

In order to prevent the auxiliary rake 5 from shifting, a limiting ring 51 is arranged at the joint of the auxiliary rake 5 and the bearing frame 2.

For the convenience of adjustment, the hand crank sleeve 31 is connected with the bearing plate 3 through a connecting plate 33.

In order to eliminate potential safety hazards, a limiting rod 6 is arranged on the traction frame 1, and the limiting rod 6 is clamped with the auxiliary rake 5.
