Abstract
The utility model discloses a folding type offset harrow and aims to provide a folding type offset harrow which enables that a machine set walks and transports on a road or transfer in a field conveniently and is simple and safe and reliable in structure. The folding type offset harrow comprises a main machine frame, a traction frame arranged on the main machine frame, land wheel assembly and two harrow sets offset in the front and in the rear. The harrow sets are divided into three segments in design, thereby two sides of the harrow sets are horizontal and symmetric folding segments and the middle of the harrow sets is a fixing segment. The harrow sections are fixed on the main frame through the fixing segment in the middle of the harrow sections. A cylinder is arranged between the folding segments of two sides of each harrow section and the fixing segment in the middle in a hinge mode. A tuck up lock frame is arranged in a fixed beam of the fixing segment in the middle. A front support of the folding segments is connected and locked with the tuck up lock frame when the folding segments are tucked up. The folding type offset harrow is applied to arrange-land working.
Description
Technical field
The utility model belongs to the disk harrow in the agricultural mechanical field, more particularly, relates to a kind of collapsible biasing rake.
Background technology
Disk harrow belongs to the scarification equipment in the agricultural mechanical field, can realize the high speed operation under the matching tractor traction, and operating efficiency is high, and is wholely effective, is widely applied in agricultural production.Particularly in recent years, in order to adapt to the demand for development of modernized big agriculture, disk harrow is to the wide cut future development.Existing wide cut disk harrow all adopts widens mainframe, the rake group is installed in the design on the mainframe, the mainframe of this technical scheme can not fold, under unit road walking transportation, field transfer case, lateral dimension surpasses the road transport width, it is very inconvenient to transport, even makes facility and the object scratching of road both sides, causes facility damage or other security incident.In addition, although existing minority wide cut disk harrow has designed the hydraulic foldable frame, complex structure can not lock after frame is folding, and security reliability is poor under the walking states.
The utility model content
The purpose of this utility model is for the problems referred to above that exist, and a kind of unit road walking transportation or field convenient transfer, safe and reliable collapsible biasing rake simple in structure are provided.
For achieving the above object, the utility model adopts following technical proposals: collapsible biasing rake of the present utility model, comprise mainframe and be installed in hitch frame on the mainframe, two rake groups of wheel assembly, front and back biasing, described rake group is designed to three sections, both sides are the lateral symmetry folded section, the centre is canned paragraph, and is packed on the mainframe by the built-in beam of middle canned paragraph; Hinged between the both sides folded section of each rake group and the middle canned paragraph folding oil cylinder is set; Arrange on the built-in beam of middle canned paragraph and turn up lock bracket, under folded section is turned up state, the front bearing on this folded section with turn up lock bracket and connect locking.
As improvement of the present utility model, the hinged end that is arranged on frame front beam of described hitch frame, an end of oblique pull oil cylinder and the other end of frame front beam are hinged, the other end of oblique pull oil cylinder and hitch frame anterior hinged.
After adopting technique scheme, the beneficial effect that the collapsible biasing rake that the utility model provides has is:
Owing to hinged between the both sides folded section of each rake group and the middle canned paragraph folding oil cylinder is set; Arrange on the built-in beam of middle canned paragraph and turn up lock bracket, under folded section is turned up state, the front bearing on this folded section with turn up lock bracket and connect locking.So when unit road walking transportation, field transfer case, by controlling the hydraulic system of driving power tractor, can easily the both sides folded section of each rake group be turned up, the constriction lateral dimension satisfies the road transport width, very convenient, and turn up rear folded section and turn up lock bracket and connect locking, guarantee that road walking and field transfer are safe and reliable, simple and compact for structure.Unit road walking transportation or field convenient transfer, safe and reliable effect simple in structure have been reached.
Description of drawings
Fig. 1 is the organigram of the collapsible biasing rake of the utility model;
Fig. 2 is that the collapsible biasing rake along the A-A line is turned up view among Fig. 1.
Among the figure: mainframe 1; Hitch frame 2; Ground wheel assembly 3; Frame front beam 4; Oblique pull oil cylinder 5; Rake group 6; Folding oil cylinder 7; Turn up lock bracket 8; Built-in beam 9; Front bearing 10.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As shown in Figure 1 and Figure 2, provided the embodiment organigram of the collapsible biasing rake of the utility model, comprise mainframe 1 and be installed in hitch frame 2 on the mainframe 1, two rake groups 6 of wheel assembly 3, front and back biasing, described rake group 6 is designed to three sections, both sides are the lateral symmetry folded section, the centre is canned paragraph, and is packed on the mainframe 1 by the built-in beam 9 of middle canned paragraph; The hinged setting folds oil cylinder 7 between the both sides folded section of each rake group 6 and the middle canned paragraph; Arrange on the built-in beam 9 of middle canned paragraph and turn up lock bracket 8, under folded section is turned up state, the front bearing 10 on this folded section with turn up lock bracket 8 and connect locking.
As preferred embodiment of the present utility model, as shown in Figure 1, described hitch frame 2 hinged ends that are arranged on frame front beam 4, an end of oblique pull oil cylinder 5 and the other end of frame front beam 4 are hinged, the other end of oblique pull oil cylinder 5 and hitch frame 2 anterior hinged.
Operation principle of the present utility model is: collapsible biasing rake is articulated on the towing plate of matching tractor, oblique pull oil cylinder 5, folding oil cylinder 7, the hydraulic fitting of wheel assembly 3 oil cylinders connect with driving power tractor hydraulic system delivery outlet, when unit advances the ground operation, handling tractor hydraulic system retracts ground wheel assembly 3 oil cylinders, folding oil cylinder 7 is stretched out make two rake groups 6 be in level, along with the collapsible biasing rake of advancing of unit begins the operation of burying.Behind the tillage operation of finishing a field, need to transfer to next piece field or road walks when returning, handling tractor hydraulic system stretches out ground wheel assembly 3 oil cylinders, increase the unit road clearance, simultaneously, make folding oil cylinder 7 retract to shorten and make the both sides folded section of two rake groups 6 be in the state of turning up, and turn up rear folded section and turn up lock bracket and connects locking, the assurance road walk and the field transfer safe and reliable.The utility model is applicable to tillage operation.
In the unit operation process, according to whole geological measuring situation, can change the angle of inclination of former and later two rake groups 6 by regulating the length of oblique pull oil cylinder 5, reach the purpose that obtains desirable operation quality.
