A walk-behind sweet potato shredded vine returning machine

Abstract

The invention relates to a device suitable for planting sweet potato seedlings and vines in small fields and high ridges on hilly slopes, crushing, removing and returning to the field. A walk-behind sweet potato shredded vine returning machine, a rear frame (1) and an engine (2) are arranged on a pair of walking wheels (20) through a chassis (4), and a pair of hand-held rods (19) protrude from both sides Equipped with a control display (3); the broken vine device (7) is hinged with the front frame 5, the left and right sides are fixed on the support wheel lifting adjustment mechanism (8), and the end is equipped with a support guide wheel (9); the metal plate cover covers There are front safety cover plate (12) and rear safety cover plate (17) on the top, left and right sides and front and back of broken vine device (7); the knife roller (15) of broken vine device (7) rotates to carry out Broken tendrils, cutter rollers (15) are installed circumferentially with cutters, close to the ground to fix the vine guide seedling grid (10) both sides oblique angles downwards in a figure-of-eight opening. The invention completes the operations of picking seedlings, pulling vines, cutting vines, crushing, and returning to the field at one time. It has the advantages of small width, light weight, convenient climbing and crossing, small volume, small turning radius, convenient transfer, guaranteed personal safety, and high operating quality. advanced features.

Description

technical field [0001] The invention relates to a device for directly crushing and returning sweet potato vines to the field before the sweet potato digging and harvesting operation in agricultural harvesting machinery, in particular to a device suitable for crushing and removing sweet potato vines for planting sweet potato vines in high ridges on hilly slopes. Background technique [0002] Sweet potato is a creeping plant that is planted in high ridges (the height of the ridge is about 22 cm at harvest, and the distance between the ridges is 80 to 90 cm). It is intertwined with the ridges and is not easy to separate. In addition, the yield of sweet potato vines is very high, and the yield per mu can reach 2,000 kilograms. Therefore, the sweet potato vines must be removed before harvesting, otherwise it will be covered in large quantities and the underlying potato pieces cannot be dug up. Therefore, it is very necessary to remove the sweet potato vines before harvesting, an...

Problems solved by technology

However, this type of equipment has a large supporting power (20-100 horsepower medium and large four-wheel tractor), the weight of the whole machine (the weight of the equipment itself is about 350-1500 kg except the tractor), large volume, and long turning radius (about 5 meters). The tractor has a large wheelbase (1 meter or more than 1.8 meters), and the required machine-plowing road is relatively wide

[0006] However, the sweet potato planting fields in hilly and sloping fields are small in size, large in slope, narrow in machine-plowing roads, multi-level in terraced fields, and short in length of planting ridges, so frequent field turns are used, so medium and large four-wheel tractors are used for hanging single-row or multi-row wide-width operations. The operation of the equipment in hilly slope areas has great limitations and inadaptability

① Four-wheel tractors are heavy, bulky, and have a large turning radius, which is difficult to adapt to hilly and sloping operations; ② Equal ridge width and vine breaking operations, large width and heavy weight, are not suitable for handling and transferring operations on hilly and sloping land; ③ Four-wheel tractors are matched The driver and passengers of the suspension-type vine-breaking operation equipment sit on the tractor, and the implements work at the rear, so the safety is relatively high. However, the operator of the walking-type vine-breaking equipment walks at the rear end of the vine-breaking operation parts, and the flying clods, Mudstone and broken knives can easily affect personnel safety

[0007] In summary, medium and large suspended single-ridge or multi-ridge vine-breaking machines can be adapted to plain dam areas and large plots of gentle slopes in hills (concentrated into more than tens of acres), but they cannot adapt to small fields in hills and slopes. The shortage of machinery for returning sweet potato shredded vines to the field in hilly and sloping land is becoming more and more serious

[0008] Due to the lack of sweet potato vine-cutting machines, manual cutting of vines is basically used in the production of sweet potatoes in small fields on hilly slopes. The contradictions of high labor intensity, high labor costs, and high labor costs are very prominent, which seriously affects farmers' enthusiasm for planting. There is an urgent need for equipment that can adapt to the cutting and vine cutting of sweet potatoes on hilly and sloping land
