Description

Quinoa field weeding tool

Technical Field

The utility model relates to the field of agricultural weeding tools, in particular to a quinoa field weeding tool.

Background

Chenopodium quinoa is originally produced in the Andes mountain area in south America, is an important food crop in the area in the first 3000 years of the Gongyuan, has unique nutritional value, is a full-nutrition food most suitable for human beings, and is concerned all over the world. In the chenopodium quinoa production, weeds do not cause the chenopodium quinoa growers to feel bitter, field weeds are mainly hoed by a hoe manually or pulled out manually or the weeds are killed by a herbicide, the manual weeding is labor-consuming and time-consuming, the labor intensity is high, the weeding efficiency is low, the production cost is high, and the chenopodium quinoa is extremely sensitive to the herbicide, so the weeds in the chenopodium quinoa field can be removed only manually, and therefore, the design of a weeding tool suitable for the chenopodium quinoa field is necessary.

Most of traditional manual handheld weeders adopt a rotary cutter which rotates at a high speed under the driving of a motor to achieve the purpose of mowing, the rotary cutter is obviously not suitable for removing weeds in quinoa fields, the row spacing in the quinoa fields is small, the row spacing is generally 30cm, if the handheld weeder is used for weeding, on one hand, the high-speed rotary cutter cannot dig into the soil to weed, only can weed, and the effect of eradicating weeds cannot be achieved, on the other hand, leaves on two sides of the quinoa are easily cut off by the high-speed rotary cutter, even plants are cut off, and the weeds in the quinoa fields cannot be removed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a quinoa field weeding tool, which solves the problem that weeds cannot be eradicated when a handheld weeding machine is used for weeding in the quinoa field in the prior art.

In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:

the utility model provides a quinoa field weeding instrument, includes the U-shaped support, and the U-shaped oral area of U-shaped support rotates installs the walking wheel, and the U-shaped root of U-shaped support is connected with crooked decurrent linking arm, and the linking arm lower extreme is connected with the blade, the blade of blade is downwards, and the U-shaped root of U-shaped support still is connected with the action bars that upwards extends, and the action bars upper end is connected with the operation handle.

Furthermore, the rim surface of the travelling wheel is formed into an uneven rough surface.

Furthermore, there are two sets of linking arms, the blade is fixed in two sets of linking arm lower extreme, and the length of blade satisfies the blade both sides and surpasss respectively corresponding direction linking arm.

Further, the acute angle between the blade and the ground is 50-70 degrees.

When the weeding tool disclosed by the utility model works, the travelling wheels are in contact with the ground of a field, the operation handle is manually held to push the weeding tool disclosed by the utility model to move forwards, the travelling wheels move forwards, and when the blade reaches a weed place, the operation rod is manually pressed downwards, so that the cutting edge of the blade is deeply buried in the field to shovel off weeds.

Compared with the prior art, the utility model has the advantages that:

the weeding tool increases the universality of the weeding tool, improves the weeding efficiency, has the efficiency 15-20 times higher than that of manual weeding, has light labor intensity, and avoids the problem that quinoa on two sides are easily accidentally injured when the existing weeding machine removes weeds among quinoa rows.

Detailed Description

The utility model is further illustrated with reference to the following figures and examples.

As shown in figures 1 and 2, the quinoa field weeding tool comprises a U-shaped support 1, wherein the front part of the U-shaped support is provided with a U-shaped mouth part, and the rear part of the U-shaped support 1 is provided with a U-shaped root part (namely a U-shaped corner).

The U-shaped mouth of the U-shaped bracket 1 is rotatably provided with a walking wheel 2. Specifically, the arm end of the left and right two arms of U-shaped support 1 is fixed with the outer lane of bearing 3 respectively, the long limit extending direction of the two arms of bearing 3's outer lane axial perpendicular to U-shaped support 1, left and right two bearings 3 are coaxial, it is equipped with the inner circle to rotate coaxially respectively in the outer lane of every bearing 3, walking wheel 2 locates between two bearings 3, walking wheel 2 is coaxial with bearing 3, 2 axial two sides of walking wheel connect in the inner circle of bearing 3 through the coaxial rotation of pivot respectively. The wheel face design of walking wheel 2 is unevenness rough surface, the area of contact in increase and field on the one hand, on the other hand in order to adapt to broken unevenness field clod.

The U-shaped root of U-shaped support 1 is connected with two sets of linking arms 4 of bending downwards again earlier backward, and two sets of 4 lower extremes of linking arm are connected with blade 5 jointly, and the long edge direction of blade 5 is along left right direction, and the blade of blade 5 is downward, and the length of blade 5 satisfies that the left and right both sides of blade surpass the linking arm 4 that corresponds the side respectively, and the whole length of blade is less than the row spacing in the quinoa wheat field. The acute angle between the blade 5 and the ground is 50-70 degrees, and the angle is preferably 40 degrees in the embodiment.

The U-shaped root of the U-shaped bracket 1 is also connected with two operating rods 6 which extend straight upwards and backwards, and the upper ends of the operating rods 6 are connected with the middle position of an operating handle 7 which is horizontal left and right. And the acute angle formed by the operating rod 6 and the U-shaped bracket 1 is smaller than the acute angle formed by the blade 5 and the U-shaped bracket 1.

As shown in fig. 3, when the operator holds the operating handle 7 to push the weeding tool of the utility model to walk on the ground, the operating rod 6 is pressed down by the operating handle 7 when the blade 5 reaches the position of the weed 8, so that the blade 5 hoes into the field where the weed 8 is located, and the weed 8 can be hoed off from the root by further pressing down.

The embodiments of the present invention are described only for the preferred embodiments of the present invention, and not for the limitation of the concept and scope of the present invention, and various modifications and improvements made to the technical solution of the present invention by those skilled in the art without departing from the design concept of the present invention shall fall into the protection scope of the present invention, and the technical content of the present invention which is claimed is fully set forth in the claims.
