Description

A vine cutting device for multi-row operations on ridgeland

technical field

The utility model relates to a vine cutting device, in particular to a multi-row operation device for removing sweet potato vines and vines, belonging to the technical field of agricultural harvesting machinery.

Background technique

Sweet potato is a vine plant planted on high ridges. Its vines grow luxuriantly. There are fibrous roots on the vines and they grow close to the ground. They can cover the entire ridge and the ground, and the ridges are intertwined and difficult to separate. . Sweet potato seedlings usually grow to 1.5-4.0 meters, and the output of seedlings and vines per mu is as high as 2000kg. Therefore, the workload of digging and removing vines before harvesting is very heavy and very hard.

In terms of production, most of the existing sweet potato seedling and vine crushing and returning machines are single-row operation equipment, with small supporting power, low operating efficiency, and many residues in furrows, which are difficult to meet the large-scale production needs of large planters. In order to meet the production demand, the existing horizontal straw crushing and returning machine for corn and other crops in China has been improved and developed into a two-row sweet potato seedling and vine crushing and returning machine. The main problems are: poor crushing effect, many residual vines, Second cleaning is required. After crushing seedlings and vines, there will still be a lot of potato vines with a length of about 1.0-2.0 meters. When the subsequent segmental harvester works, these potato vines will hang on both sides of the harvester and accumulate in large quantities. It is necessary to stop the harvester for cleaning, so the harvester cannot work smoothly, so it is necessary to use manual or auxiliary tools to clean up the residual vines; it is hard-connected with the tractor using a three-point suspension, which is greatly affected by the tractor's driving route, up and down, left and right bumps, and the shape of the ridge. , The quality of the work is poor, and the soil is often hit on one ridge, while the top of the other ridge has not been cut clean.

Utility model content

The purpose of this utility model is to propose a vine cutting device for ridges that can work across two ridges, is not affected by the swaying of the tractor, and has a good crushing effect.

In order to achieve the above purpose, a vine cutting device for multi-row operations in ridgeland of the present utility model includes a frame box body supported by a traction frame at the front end, and the traction frame is externally connected to a tractor; one side of the box body is provided with a drive pulley group; The frame is a three-point suspension traction frame. The bottom of the car body is open and has two opposite side plates. A knife roller shaft is arranged in the middle of the car body. There are crushing knives in a spiral arrangement, one end of the crushing knife is fixed on the cutter roller shaft, and the other end is the working end. When the rotating shaft cylinder drives the pulverizing knife to rotate, the rotating curved surface formed by the working end of the pulverizing knife along the axis of the rotating shaft cylinder is imitated Ridge and trapezoidal structure, imitating ridge-shaped crushing knife group, effectively removes seedlings and vines on the top, side and furrow of the ridge (imitating the ridge and trapezoidal structure, the raised ridge at the field boundary is called a ridge, and the depression between the ridges is called a ditch, imitating The ridge-trapezoidal structure is the corrugated structure formed by the combination of ridges and furrows).

The preferred version of the utility model is:

Preferably, the bottom of the traction frame and the rear end of the box body are equipped with a depth-limiting wheel assembly. When traveling, the implement is connected to the tractor by three-point suspension. When operating, the tractor will lower the vine cutting device to cut. The depth-limiting wheel support operation, the tractor only plays the role of traction and power supply, the implement is less affected by the tractor, and is in a floating operation state, which eliminates the influence of the tractor's left, right, up and down bumps on the operation of the rear-end crusher, and the operation quality of two ridges at a time Higher; the depth-gauge wheel assembly includes a depth-gauge wheel with an axle, and the two ends of the depth-gauge wheel axle at the bottom of the traction frame are respectively supported on the supporting wheel frame at the bottom of the traction frame; They are respectively supported on the brackets fixedly connected to the corresponding side plates, so that the brackets can form a secondary frame structure with the box body, which enhances the rigidity of the whole machine, and effectively improves the support of the machine tool and the stability of the operation.

Preferably, the depth-gauge wheel at the bottom of the traction frame is a height-adjustable rubber depth-gauge wheel, and the depth-gauge wheel at the rear end of the box is a wide-width depth-gauge wheel with adjustable height. To adjust the actual height of the equipment from the ground, there are soil removal devices on the bottom of the traction frame and the depth-limiting wheel at the rear end of the box body, which is to prevent the change of the depth-limiting height caused by the sticking of soil.

Preferably, it also includes a secondary crushing device arranged parallel to the cutter roller shaft, the bottom of the secondary crushing device is fixed on the front side plate of the frame box, and the end of the secondary crushing device near the cutter roller shaft is a corrugated imitation ridge Trapezoidal structure, and the gap between the secondary crushing device and each crushing knife is kept at 30mm. The setting of the secondary crushing device is to crush the broken seedlings and branches picked up by the cutter for secondary crushing, effectively providing crushing effect .

The beneficial effects of the utility model are: the utility model can cut multiple ridges at the same time, prevent the vines from being entangled, reduce the wear of the shaft of the crushing knife, and cut the vines thoroughly without leaving uncut long vines, which is conducive to the smooth operation of subsequent harvesters.
