Description
Technical Field
The invention relates to a wafer type double-row cotton stalk pulling device, and belongs to the technical field of agricultural machinery.
Background
The cotton stalk is used as an important biomass energy source and has obvious economic benefit. The cotton stalks are harvested manually, so that the labor intensity is high, the efficiency is low and the cost is high; the incineration treatment of the cotton stalks not only pollutes the environment, but also wastes valuable natural resources.
According to the knowledge of the applicant, some cotton stalk pulling mechanisms are already available in the market, but the existing cotton stalk pulling mechanisms usually adopt a fluted disc type or fluted roller type mechanism, and have bending or shearing action on cotton stalks when the cotton stalks are pulled out, so that the cotton stalks are easy to break when the cotton stalks are pulled out, particularly the cotton stalks in Xinjiang areas, the stalks are fine due to varieties and planting modes, the breaking rate of the existing cotton stalk pulling mechanisms is high, and the roots of the cotton stalks can remain in soil after the cotton stalks break, so that much inconvenience is brought to subsequent agricultural operation, and even the planting of crops in the next season is influenced. Therefore, how to avoid the cotton stalk from being pulled off in the pulling-off process becomes a problem to be solved urgently.

In order to solve the technical problems, the technical scheme provided by the invention is as follows: a wafer-type double-row cotton stalk pulling device comprises a rack, a left chain transmission mechanism, a right chain transmission mechanism and a middle chain transmission mechanism, wherein the left chain transmission mechanism and the right chain transmission mechanism are arranged on the rack at preset inclination angles with a horizontal plane, the middle chain transmission mechanism is vertically arranged on the rack, and the bottom of the middle chain transmission mechanism is consistent with the horizontal inclination angles of the left chain transmission mechanism and the right chain transmission mechanism;
each outer chain plate of the left chain transmission mechanism is provided with a left auxiliary plate which is parallel to the outer chain plate and has elasticity, each outer chain plate of the right chain transmission mechanism is provided with a right auxiliary plate which is parallel to the outer chain plate and has elasticity, and each outer chain plate of the middle chain transmission mechanism is provided with a middle auxiliary plate which is vertical to the outer chain plate and has elasticity;
the left auxiliary plate and the right auxiliary plate respectively correspond to the position and the movement speed of the middle auxiliary plate, a left strip-shaped gap for removing cotton stalks is formed between the left auxiliary plate close to one side of the middle chain transmission mechanism and the middle auxiliary plate positioned at the bottom of the middle chain transmission mechanism, and a right strip-shaped gap for removing cotton stalks is formed between the right auxiliary plate close to one side of the middle chain transmission mechanism and the middle auxiliary plate positioned at the bottom of the middle chain transmission mechanism; the left and right strip-shaped gaps are obliquely arranged and gradually rise from front to back along the advancing direction, and the distance between the left and right strip-shaped gaps is matched with the distance between two rows of cotton stalks.
When the cotton stalk puller is used, the distance between the left strip-shaped gap and the right strip-shaped gap is matched with the distance between two rows of cotton stalks, the device is arranged on agricultural operation machinery such as a tractor and the like through the rack, the whole device is driven by the rack to move forwards, so that the two rows of cotton stalks enter the left strip-shaped gap and the right strip-shaped gap respectively, the two rows of cotton stalks are pulled out under the clamping of the left attachment plate and the middle attachment plate and the clamping of the right attachment plate and the middle attachment plate along with the movement of the left strip-shaped gap and the right strip-shaped gap backwards and upwards, namely, the two rows of cotton stalks can be pulled out at one time, and compared with the prior art that only one row of cotton stalks can be pulled out.
In addition, the moving speed of the left and right strip-shaped gaps in the horizontal direction can be the same as the horizontal speed of the whole device by adjusting the advancing speed of the rack, so that the cotton stalks are lifted vertically when being pulled out, and are not affected by bending or shearing force any more, so that the cotton stalks can be pulled out smoothly as long as the clamping force is enough, and the phenomenon of pulling-out the cotton stalks is avoided. The applicant tests show that when the cotton stalk is only stretched, the damage limit is very high and far higher than the force required for pulling the cotton stalk, so that the device can reduce the breaking rate of the cotton stalk and reduce the quantity of the cotton stalk root remained in the soil when the cotton stalk is pulled, thereby facilitating the subsequent agricultural operation.
