Abstract

The utility model discloses a tuber crop harvester. The tuber crop harvester comprises a frame, wherein, a gearbox is mounted on the frame; a shovel blade inclining towards the ground is fixedly connected with the lower part of the front end of the frame; soil flow dividing holes are formed on the two sides of the front end of the frame; and two groups of shearing devices connected to the frame are respectively arranged above the two sides of the shovel blade and dynamically connected with the gearbox through a crank and connecting rod mechanism connected to the frame. The harvester with the structure has the advantages and effects that the structure is simple, the running resistance is small, and the machine cannot get stuck.

Description

The tuber crops reaping machine

Technical field

The utility model relates to a kind of machinery of gathering in the crops tuber crops.

Background technology

Existing tuber crops reaping machine, is 200820023793.9 as the applicant in the patent No., name is called in the Chinese patent file of " a kind of improved potato type harvesting machine " and discloses a kind of machinery of gathering in the crops tuber crops, this machine comprises by left and right sidesing wall plate and connects the frame that the entablature of left and right sidesing wall plate constitutes, the front end of frame is provided with hanger bracket, frame is provided with gearbox, the rear end of left and right sidesing wall plate is provided with the final drive shaft that is connected with gearbox power, the front end of left and right sidesing wall plate is provided with driven voller, be provided with the transmission separator between final drive shaft and driven voller, frame is provided with gauge wheel, and the leading section of described left and right sidesing wall plate is provided with the soil tap hole.The inboard of left and right sidesing wall plate is provided with to drive transmits the jumping wheel that separator is beated.A soil part that is scooped up during operation is shunted in advance through the soil tap hole, remaining really separates with administration through transmitting separator again, the soil shunting is accelerated, avoided soil transmitting bulk deposition on the separator, make this machine need power to diminish, also improved production efficiency accordingly.But, in actual job, because the climing usually weave in of crop its seedling in process of growth, reaping machine is advanced in the process, it is climing to enter the seedling that the climing meeting of seedling in the reaping machine pullling the reaping machine outside, therefore can cause climing the healing of seedling to amass the more, not only increase the resistance that reaping machine advances, but also can stuck reaping machine.

Summary of the invention

The technical problems to be solved in the utility model is at above-mentioned defective, and a kind of climing tuber crops reaping machine that gathers of seedling that can not cause is provided.

For solving the problems of the technologies described above, the utility model provides a kind of tuber crops reaping machine of following structure, comprise frame, gearbox is housed on the frame, frame front end bottom is connected with the perching knife on oblique ground, frame front end both sides are provided with the soil tap hole, and its design feature is: top, described perching knife both sides is respectively equipped with two groups of shears that are connected on the frame, and two groups of shears are connected with gearbox power by the toggle that is connected on the frame.

As a kind of embodiment of shear, described shear comprises being connected in decides snip and the active cutter plate that is slidingly connected on the frame on the frame, and active cutter plate is connected with toggle power.

In order to improve shear efficiency, the described shear blade indentation of deciding snip and active cutter plate.

A kind of implementation as toggle, described toggle comprises that the crank that is connected with gearbox power, hinge are contained in two connecting levers that rocker stand on the frame and hinge are contained in the frame both sides, crank links to each other with rocker stand by master connecting-rod; rocker stand links to each other with two connecting levers respectively by two slave connecting rods, and two connecting levers are passed connecting rod by two and linked to each other with two groups of shears respectively.

The lower end of described rocker stand is connected with and the corresponding hack plate in soil tap hole position.

The reaping machine of said structure, on the basis of existing technology, by shear is set, the climing shearing of seedling that just machine in the machine can be linked to each other outward separates, can not cause that seedling is climing to be gathered on reaping machine, thus make the utlity model has simple in structure, walking resistance is little and the advantageous effect that can not block machine.

Description of drawings

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1.
