Description

Automatic soil taking device of soil accumulating box of film paving machine

Technical Field

An automatic soil taking device of a film paving machine soil accumulating box is a device which is used for realizing automatic soil taking and conveying to the soil accumulating box by a film paving machine which is used for planting crops in the operation of paving mulching films, realizing automatic film breaking and soil pressing at the head of a land and restarting the operation of automatic soil pressing.

Background

In the existing automatic soil-pressing film-paving machine, the following defects exist:

1. The full-film machine usually adopts the back output power, fetches the soil in a rotary tillage way, and then conveys the soil to the soil separating box for film pressing, so the machine has large energy consumption and high production cost, and does not realize the automatic film breaking at the ground and start the automatic soil pressing function.

2. The soil taking mode adopted by the soil accumulating box of the existing automatic film breaking machine is mostly a postposition or offset large-diameter waterwheel type rotating wheel soil taking device, the device has a heavy and non-compact structure and can only be used for the single function of laying mulching films, and when the device needs to be used for the work of film laying and hole sowing at the same time, the functions of automatically breaking and pressing soil and restarting to automatically press soil cannot be realized.

DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION

The embodiments of the present invention are described in detail below with reference to the accompanying drawings: as shown in figures 1 and 2, in the device consisting of a film spreading rack 1, a soil accumulating box 2, land wheels 4 and land wheel shafts 8, a driving chain wheel 6 is arranged in the middle of the land wheel shaft 8, bearings 7 are symmetrically arranged on two sides of the land wheel shaft respectively, semicircular fork seats 5 matched with the bearings 7 arranged on the land wheel shaft 8 are arranged at the lower two ends of a soil taking device framework 3, so that the soil taking device framework is convenient to assemble, and a U-shaped conveying groove 15 is formed by bending a steel plate and is arranged below the inner two sides of the soil taking framework 3 by bolts. In the operation of the device, sundries are difficult to block, therefore, in order to solve the problem, a chain telescopic frame outer sleeve 13 is stitch-welded at the upper two ends of a soil sampling device framework 3, an adjusting screw 14 is arranged at the bottom of the chain telescopic frame outer sleeve 13, a sliding block 19 and a spring 20 are arranged in the chain telescopic frame outer sleeve 13, and a bearing seat bearing 10, an upper end shaft 11 and an upper chain wheel 9 are arranged at the top end of a chain telescopic rod 12 to enable the soil sampling chain 17 to be bent and reset automatically. The front upper end of the soil sampling device is arranged at the front upper part of the soil accumulating box 2, the middle lower part and the outer two sides of the soil sampling device framework 3 are welded with porous fixing pieces 18 corresponding to the breaking beams 23, and the central lines of the plurality of holes are uniformly distributed by taking a land wheel shaft as the center of a circle, so that the angle between the automatic soil sampling device framework and the ground can be adjusted and fixed. Because different ground conditions exist in the film paving operation, the soil collecting plate 16 which can adjust the height above the ground is arranged at the bottom of the U-shaped conveying groove 15 close to the ground so as to adjust the soil taking amount.

As shown in fig. 3: during the film laying operation, as the conveying chain can not leave the soil, the more the soil is pressed into the grooves 21 of the chain wheel, the more the soil is accumulated, the chain is broken and the operation is not possible, therefore, the soil grooves 22 are respectively processed on the outer two sides of all the inter-tooth grooves 21 of the driving chain wheel 6 and the upper chain wheel 9, the cross section of the soil grooves is in a ridge shape, and the accumulated soil can be automatically extruded by the chain roller.
