Description

New Pulling and Cutting Combined Cotton Stalk Harvester

technical field

The utility model relates to an agricultural machine, in particular to a novel pulling and cutting combined cotton stalk harvester, which can complete multiple operations such as pulling, chopping and collecting cotton stalks at one time.

Background technique

At present, the domestic cotton stalk harvesting machinery can be divided into two types: segmental harvesting machinery and combined harvesting machinery in terms of harvesting process. Segmented harvesting machinery includes stalk pullers, picking and shredders, etc. The extraction, chopping, and collection of cotton stalks require different machinery to complete, which results in increased workload, high labor intensity, and low harvesting efficiency; the existing automatic Walking combined operation machinery does not extract cotton stalks, but cuts and harvests cotton stalks. The stubble of cotton stalks remains in the soil, which not only results in low utilization of cotton stalks, but also makes subsequent farming difficult. At the same time, due to the high price of this type of machinery, Factors such as high operating costs restrict the application of this type of machinery.

In addition, a cotton stalk harvester is disclosed in the patent (CN201860583U). The picking device, chain plate conveying device, feeding device, chopping device, throwing device, and stalk pulling mechanism of the cotton stalk harvester are all arranged on the tractor. In the front, in this case, the tractor needs a lot of power to drive this device, which cannot be used by ordinary tractors; in addition, due to the limitation of the space position and the overall front suspension mechanism, the extraction mechanism is directly connected to the pick-up mechanism, and the distance between the two If it is too close, the picking distance will be too short, and the state of the straw cannot be adjusted in time, which will cause the picking mechanism to be unsmooth and even blocked.

Utility model content

The utility model is matched with a tractor, adopts a pull-cut combined scheme design, overcomes the shortcomings of the existing cotton stalk harvester, and provides a new pull-cut combined cotton stalk harvester.

The technical scheme that the utility model adopts is as follows:

The new-type combined cotton stalk harvester mainly includes a tractor, a stalk pulling mechanism, a connecting mechanism, a picking mechanism, a feeding mechanism, a shredding mechanism, a throwing mechanism, a suspension mechanism, and a material box. The mechanism is arranged on the head of the tractor, and the described picking-up mechanism, feeding mechanism, chopping mechanism and throwing mechanism are installed behind the tractor, and a material box is installed on the top of the tractor.

The picking-up mechanism, the feeding mechanism, the chopping mechanism and the throwing mechanism are installed on a frame, and the frame is connected to the rear of the tractor through a suspension mechanism.

The frame is driven up and down by the hydraulic power of the tractor, the power output shaft of the tractor is connected with the front end of the transmission mechanism, and the rear end of the transmission mechanism is connected with the frame.

The frame is driven up and down by the hydraulic power of the tractor, and they realize power transmission through a transmission mechanism. connected to realize power connection.

The picking mechanism is connected with the feeding mechanism, the feeding mechanism is connected with the shredding mechanism, the shredder is connected with the throwing mechanism, and the throwing mechanism corresponds to the material box.

A hydraulic turning mechanism is installed at the bottom of the material box.

The tractor, stalk pulling mechanism, connection mechanism, picking mechanism, feeding mechanism, shredding mechanism, throwing mechanism, suspension mechanism, and material box are all prior art, and will not be described in detail here.

The working process of the utility model is: the cotton stalk harvester is installed on the tractor, driven forward by the tractor, the stalk pulling mechanism at the front end moves forward passively through the transmission mechanism under the push of the tractor, and drives the stalk pulling toothed disc to rotate to realize cotton stalk pulling. unplugged. The extracted cotton stalks pass through the bottom of the tractor and are picked up by the pick-up mechanism, then sent to the feeding mechanism for extrusion, and then fed to the shredding mechanism for shredding. The shredded cotton stalks are thrown together with the shredder The leaves are collected into the material box by the throwing device, and can also be sprayed into the field as fertilizer for straw returning to the field according to user needs. The power at the rear of the tractor is obtained from the rear output shaft of the tractor and transmitted to various mechanisms through the transmission mechanism.

The beneficial effects of the utility model are:

(1) The stalk pulling mechanism is arranged separately from the picking mechanism, feeding mechanism, shredding mechanism, and throwing mechanism, which reduces the load on the front end of the tractor and puts most of the weight on the rear end of the tractor, so that the whole machine has a greater impact on the tractor. The requirements are greatly reduced, and ordinary tractors can also be matched.

(2) The straw pulling mechanism is separated from the picking mechanism, which increases the picking distance, and combines with the widened picking mechanism and feeding mechanism to realize the smooth feeding of straw.

Detailed ways

The present invention is described in detail below in conjunction with accompanying drawing:

As shown in Figure 1, the stalk pulling mechanism 1 is directly connected to the front end of the tractor through the connecting mechanism 2, and the connecting mechanism 2 is equipped with a hydraulic cylinder, which can realize the lifting of the stalk pulling mechanism 1 under the action of hydraulic power; the picking mechanism 11, the feeding mechanism 6 , shredding mechanism 7, and throwing mechanism 9 are directly installed on the frame 4, and the frame 4 is connected with the rear end of the tractor through the suspension mechanism 3, and is installed on the frame 4 by bolts, and the frame 4 is driven by the hydraulic power of the tractor.
