Description

The towed weeding device that loosens the soil

Technical field

The utility model relates to a kind of scarifier attachment, is specially the towed weeding device that loosens the soil.

Background technology

The healthy growth of crops depends on the nutrient that can better be absorbed by soil of an amount of oxygen, humidity and capacity.But inevitably weeds can appear in the process of crop growth.If weeds are too many, make become drying and surface of soil sclerosis also can occur thereby will absorb large quantity of moisture as sponge, so just hindered moisture, nutriment is absorbed by the lawn.In addition, weeds also can promote the growth of moss, algae and careless bacterium spore, and these plants all can have a negative impact to the growth of crop, are the important steps in the plant growth so remove the gap of weeds and control soil.Suitable loosening the soil also can help to weed a garden.

The soil time has been grown easy caking, has so just reduced the gas permeability of following, and as airtight the same root, ploughs after the pine, and the space between the soil particle is strengthened, and air is just entered easily, has increased the breathing of root cells; Respiration has been strengthened; Can strengthen transpiration; Promoted the exchange of the mineral element in root hair and the soil, so also just can promote the absorption of root to mineral element to have destroyed the root system of weeds simultaneously; Can accomplish the work of weeding, loosening the soil is the weeds of removing profound and soil layer surface coverage through mechanical system.

Loosening the soil through equipment is the mode of the most simply loosening the soil; The rake that often uses like people is to be processed by the iron and steel of high ductibility, has a lot of continuous teeth above, when firmly pressing down the main shaft of rake; Tooth will penetrated surface; Be to handle a kind of ideal on grassland, zonule and cheap instrument, but its labour intensity is big, can only be applicable to loosening the soil and weeding among a small circle.Loosenning tiller mainly is made up of electromotor, reduction gearing, running gear, the cutter that loosens the soil, depth adjustment mechanism etc.Electromotor provides power, is connected with the reduction gearing axle through shaft coupling.Small-sized loosenning tiller is to carry out fragmentation, become flexible or cut a hole the construction machinery that splits hard soil layer with tine, mainly is made up of electromotor, reduction gearing, running gear, the cutter that loosens the soil, depth adjustment mechanism etc.; But all be self-propelling machinery, exist complex structure, it is difficult to make, and cost is high, can't draw suspension, the problem that cooperate degree is low.

Summary of the invention

The towed weeding of the utility model device that loosens the soil comprises frame 1 and loosens the soil cutter 2, it is characterized in that, and described frame 1 rectangular framework, rotate and be provided with roller bearing 3 on one side, corresponding another side is provided with hanger bracket 4; The described cutter 2 that loosens the soil is arranged on roller bearing 3 outer circumference.

Further, described hanger bracket 4 fixedly installs perpendicular to frame 1, also is provided with between hanger bracket 4 and the frame 1 to reinforce gusset 5.

Further, the described cutter 2 of loosening the soil per four be one group along radially evenly the distributing of roller bearing 3, roller bearing 3 axially be provided with the some groups of cuttves 2 that loosen the soil, the cutter 2 interlaced settings of loosening the soil of two adjacent groups.

Further, also be provided with stationary knife 7 through fixed mount 6 on the described frame 1, fixed mount 6 two ends are connected with frame 1, and the middle part is parallel to roller bearing 3, and stationary knife 7 evenly is provided with respect to two groups of gaps of loosening the soil between the cutter 2.

Further, be provided with the protective cover 8 that is circular-arc between described fixed mount 6 and the frame 1, protective cover 8 is positioned at frame 1 top, and its radius is greater than the distance of roller bearing 3 axle center to cutter 2 tops of loosening the soil.

Further, the described free end that loosens the soil cutter 2 and stationary knife 7 is arc-shaped bend, and the bending direction of the cutter 2 that loosens the soil is identical with curvature, and the bending direction of stationary knife 7 is opposite with the cutter 2 that loosens the soil, and curvature is identical with the cutter 2 that loosens the soil.

The towed weeding of the utility model device that loosens the soil through the cutter 2 that loosens the soil that is provided with on roller bearing 3 outer circumference, is accomplished the weeding in soil and is loosened the soil when under the traction of tractor, rolling, simple in structure, easy to make; Also realize to the filter of weeds comb with to the fragmentation of soil block simultaneously through being arranged on stationary knife 7 on the fixed mount 6, the effect that has better improved weeding with loosen the soil the uniformity; Its beneficial effect is that reasonable in design, structure is ingenious, makes simply, and with low cost, processing and fabricating is convenient, can be used with power agricultural machinery, and is applied widely.
