Description

Rake plows

Technical field

The utility model relates to a kind of tillage implements, and more particularly, it relates to the one rake that plows.

Background technology

The rake that plows is a kind of conventional tillage implements, and it comprises rake body and is arranged on the rake teeth on rake body. The rake that plows is broken up the soil block of bulk after playing ground at plough. But the existing rake that plows, to soil soft or hard degree bad adaptability, in operation process, as runs into the barriers such as stone and can not avoid in time, thereby cause the breakage of ploughshare.

Application number is that the Chinese patent of CN201520016932.5 discloses the one rake that plows, and this rake that plows is adjusted the tooth pitch of rake teeth by PLC and cylinder, in the soil of many stones, tooth pitch is broadened, and allows stone pass through, thereby protection rake teeth prevents rake teeth fracture. But, the complex structure of this rake that plows, cost is higher, and safeguards inconvenience.

Utility model content

The deficiency existing for prior art, the purpose of this utility model is to provide the one rake that plows

For achieving the above object, the utility model provides following technical scheme:

The one rake that plows, comprise rake body and be arranged on the rake teeth on rake body, it is characterized in that: on described rake body, be provided with the chute consistent with rake teeth quantity along its width, the end of described rake teeth is located in chute, described rake teeth is connected with chute slippage and can slides along the length direction of chute.

The utility model is further set to: in described chute, be also provided with return unit, described return unit is used for making rake teeth to get back to initial position.

The utility model is further set to: described return unit is spring, and one end of described spring and the inwall of chute are fixed, and the other end and the rake teeth of spring are fixed.

The utility model is further set to: described rake teeth is lozenges towards the one side of the rake front end that plows.

The utility model is further set to: described in plow on rake and be also provided with and prevent that soil from entering the shelter of chute.

The utility model is further set to: described shelter is bellows, and two mouths of pipe of described bellows are tightly connected with the edge of chute and the outer wall of rake teeth respectively.

Compared with prior art, the utility model has the advantages that: plow rake teeth and the rake body slippage of rake of the utility model is connected, rake teeth is understood from line slip encountering after stone; make the tooth pitch of two rake teeths become large; to allow stone pass through, the utility model can effectively be protected rake teeth, prevents rake teeth fracture. In addition, of the present utility model simple in structure, manufacturing cost and use cost is low, be applicable to promote.

Detailed description of the invention

As shown in Figure 1, the utility model plows to harrow and comprises rake body 1, rake teeth 3 and the connecting portion 2 for the rake that plows is connected with hauling machine.

With reference to Fig. 3, on rake body 1, be provided with the chute 4 of cross sectional shape for " protruding " shape, and in chute 4, be provided with " protruding " shape slide block 5, the end of rake teeth 3 and slide block 5 are fixing. When the rake that plows moves in the ground, if rake teeth 3 runs into less stone, because the profile of stone is generally with radian, after the Surface Contact of rake teeth 3 and stone, under the effect of the curved surfaces of stone, stone can produce and promote the component that rake teeth 3 moves along chute 4 pressure of rake teeth 3, under the effect of this component, rake teeth 3 can move along chute 4, be offset its original position, make rake teeth 3 smoothly by stone, and the situation that rake teeth 3 ruptures can not occur. If stone is larger, adjacent two rake teeths 3 of rake on body 1 contacts with stone simultaneously, under the effect of the curved surfaces of stone, two rake teeths 3 towards mutually away from direction move, make the tooth pitch increase of two rake teeths 3, so that allow stone pass through. As optimization, rake teeth 3 is lozenges towards the one side of the rake front end that plows. In order to allow rake teeth 3 there is reset capability, in chute 4, be provided with spring 6, the inwall of one end of spring 6 and chute 4 is fixed, and the other end of spring 6 and rake teeth 3 are fixing. As shown in the figure, under original state, slide block 5 is positioned at the middle part of chute 4, is equipped with spring 6 at the two ends of slide block 5, and this structure makes rake teeth 3 have the ability of two-way reply. A spring 6 also can be only set in chute 4, and the initial position of slide block 5 is arranged on to the end of chute 4, still, this structure can only be towards sliding on one side after making rake teeth 3 run into stone, the capacity of self-regulation of harrowing that makes to plow seems not enough, therefore preferentially adopts the structural design of dual spring 6. In addition for to prevent that soil from entering chute 4 and affecting normally sliding of slide block 5, on rake, be provided with shelter plowing, this shelter can cover chute 4, and shelter can be towards the moving direction all directions twisting of rake teeth 3. Shelter can be cloth, leather, bellows 7 etc. Because the wearability of cloth is poor, leather is comparatively expensive. Here preferentially select bellows 7, two mouths of pipe of bellows 7 are tightly connected with the edge of chute 4 and the outer wall of rake teeth 3 respectively, and wherein ripple 7 pipes are riveted with the edge of chute 4, and bellows 7 is bonding with the outer wall of rake teeth 3.

The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection domain of the present utility model. It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
