Description

a push hoe

technical field

The utility model belongs to an agricultural tool, in particular to a hand-push hoe.

Background technique

Hoeing (or plowing) can not only remove weeds in the field, prevent weeds from competing with crops for water, nutrients and sunlight, but also loosen the surface soil, cut off capillary water evaporation in the soil, and play a role in water and moisture conservation. In the prior art, two kinds of tools are mainly used for hoeing: cultivating hoe and hoe, and cultivating hoe includes motorized cultivating hoe and animal power cultivating hoe. The disadvantages of loosening the soil and eradicating the weeds on the back of the ridge are: if the hoe is too wide, it is easy to damage the seedlings; if the hoe is too narrow, the effect of weeding and loosening the soil is not good, and the weeds that are too close to the furrow are not easy to To be eradicated, the land needs to be plowed again. The hoe is also the most commonly used agricultural tool. It is still used frequently in actual production. In the actual operation of hoeing, the operator needs to keep performing "lifting the hoe, dropping the hoe, bending over and pushing back hard". The reciprocating action of "pull hoe" has high labor intensity and low work efficiency.

Contents of the invention

The purpose of the utility model is to overcome the defects of the above-mentioned prior art, and provide a hand-push hoe, which has a simple structure, is convenient to operate, is lightweight and convenient, saves time and effort, has good loosening and weeding effects, and high field work efficiency.

The purpose of this utility model is achieved as follows: a hand push hoe, characterized in that: it includes a main beam composed of a lower beam and an upper beam, the front end of the beam is connected to a front fork, and a support wheel is installed on the front fork. The upper end is connected with a hoe handle; the rear part of the crossbeam is connected with a casing extending downward, the lower end of the inclined beam is connected with a pole extending downward and supporting the casing, and a hoe is installed at the lower end of the casing through fastening screws.

Further, the inclined beam includes a lower outer sleeve and an upper inner sleeve, 2 to 6 expansion gaps are set at the lower end of the inner sleeve, and tensioning screws that run through both ends of the inner sleeve are arranged inside the inner sleeve, and the lower end of the tensioning screw is a brace Tighten the truncated cone nut at the lower end of the inner casing, and the upper end of the inner casing is connected with a hoe handle.

Further, the hoe handle is a horn handle, rubber handles are installed at both ends of the horn handle, and the horn handle is connected to the upper end of the inner casing through the stem.

Further, the angle between the beam and the inclined beam is 120°-135°.

Further, the hoe shovel includes a shovel handle, and an isosceles triangular shovel blade with an apex angle of 130°-170° is fixed at the lower end of the shovel handle.

Further, the front end of the isosceles triangular blade is inclined downward, and when the front end of the isosceles triangular blade and the supporting wheels are supported upright on the ground, the plane of the isosceles triangular blade forms an included angle of 5°-10° with the ground.

Further, the hoe shovel includes a shovel handle, an inverted V-shaped shovel is fixed at the lower end of the shovel handle, and earth-building wings are arranged on the upper parts of both sides of the inverted V-shaped shovel.

Further, the supporting wheel is composed of a rim, spokes and a hub.

Further, a mud scraper is installed on the lower side of the front fork.

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

1) The present invention is mainly composed of main beam, support wheel, hoe handle and hoe shovel. It has simple structure, resource saving, low cost and easy manufacture.

2) When the present invention is hoeing, it adopts the form of pushing forward along the furrow to realize the hoeing operation. Compared with the conventional hoe hoeing operation, it does not need to perform laborious and laborious operations such as repeatedly "lifting the hoe and dropping the hoe". Convenient, time-saving and labor-saving, it not only achieves the effect of loosening soil and weeding, but also greatly improves the efficiency of field work.

3) The present invention can be matched with various types of hoe shovels, and shovels of suitable width can be used according to the row spacing, so as to remove weeds in the field to the greatest extent. In addition, using an isosceles obtuse-angle isosceles triangle blade has the functions of weeding and soil loosening; when using an inverted V-shaped blade, since the upper parts of the inverted V-shaped blade are equipped with soil-cultivating wings, it not only has the function of weeding, but also has the function of cultivating soil. . In the specific operation in the field, according to whether the actual situation needs soil cultivation operation, select and install the blade of the corresponding configuration.

4) The isosceles obtuse angle isosceles triangular spatula or the inverted V-shaped spatula adopted in the present invention have their front ends inclined downwards, and their inclination angle is 5-10°. Through repeated field practice verification, the angle is scientific and reasonable, convenient The hoe shovels into the soil, and the resistance in the soil is very small during the specific operation, and the operation is smooth, saving time and effort.

5) The hoe handle of the present invention is a horn handle, rubber handles are installed at the two ends of the horn handle, and the horn handle is connected to the upper end of the inner casing through the handle. The horn handle conforms to the principles of human mechanics, and is easy to operate and labor-saving. The horn handle is connected to the upper end of the inner casing through the stem. The angle of installation of the horn handle can be adjusted at any time, which is completely suitable for people of different heights and operating habits. In addition, the use of rubber grips, especially wear-resistant tendon grips, is comfortable to the touch and can avoid problems such as sweating, slipping and wrist soreness caused by long-term operation in the field.

6) The inclined beam of the present invention is a telescopic structure, and its structure is simple and reasonable, and the installation is stable and reliable. The length of the inclined beam can be adjusted anytime and anywhere to meet the needs of people of different heights for hoeing.

7) A rolling support wheel is installed on the lower side of the front fork. The role of the support wheel is equivalent to a lever fulcrum, which helps to adjust the shovel up and down and left and right during the hoeing operation, so as to facilitate the eradication of weeds in the furrow.

8) The angle between the beam and the inclined beam is 120°-135°. This angle is also obtained through repeated field practice verification. This structure and angle are more reasonable, easy to operate, and save time and effort for hoeing.

9) The supporting wheel is composed of a rim, spokes and a hub, and has a simple structure, saves resources, is light and convenient, and is easy to operate.

10) Installing a mud scraper on the front fork can not only remove the soil on the rim at any time, but also completely ensure that even in the field with heavy soil, the operation can be carried out smoothly, and it can also save the physical strength of the field operator and improve the its labor efficiency.
