Description

Wheat hoeing device

Technical Field

The utility model relates to the technical field of agricultural machinery, in particular to a wheat hoeing device.

Background Art

Hoeing is an effective measure to conserve soil moisture, increase temperature and promote early growth. After the beginning of spring, as the temperature rises, soil evaporation increases, and "spring rain is as precious as oil", and there are uncertainties in precipitation. Therefore, in order to prevent spring drought, it is very important to do everything possible to preserve underground moisture. Hoeing is carried out on all kinds of wheat fields when the surface soil thaws 2 cm in early spring (top frost period) to maintain soil moisture, increase surface temperature, eliminate overwintering weeds, and take the initiative in wheat field management in the later stage.

At present, hoeing is mostly done manually or with a hoeing machine. Manual work is labor-intensive and inefficient, while hoeing machines have disadvantages in terms of hoeing depth. In addition, the harrow teeth can easily cause damage to the wheat.

Utility Model Content

In order to improve agricultural production efficiency, reduce labor costs, and reduce agricultural labor intensity, the utility model provides a highly efficient and convenient wheat hoeing device. The utility model is implemented through the following technical solutions.

A wheat hoeing device comprises a frame;

A suspension mechanism for hanging on a tractor is fixedly provided at the middle of the front end of the frame, and depth limiting wheels for adjusting the hoeing depth are symmetrically connected to the inner walls of both sides of the frame, and the depth limiting wheels are fixedly provided on a rotatably adjustable threaded assembly;

The rear end of the frame is provided with two rows of rake tooth columns which are arranged in a front-to-back distribution. The bottom of each row of rake tooth columns is provided with a plurality of rake teeth at equal intervals along the length direction thereof, and the front and rear rake teeth are arranged in a staggered manner.

Furthermore, a connecting rib is fixedly provided between the upper rear side of the upper suspension frame of the suspension mechanism and the rear end of the frame.

Furthermore, the angle of the rake teeth is bent backwards to 30 degrees.

Beneficial effects of the utility model:

1. The extension length can be adjusted to control the depth of the rake teeth into the soil;

2. The angle of the rake teeth is bent backwards at 30 degrees, which can effectively prevent the rake teeth from hooking the wheat roots and stems, causing damage when pulling out;

3. The structure is stable, safe and reliable.

DETAILED DESCRIPTION

In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Generally, the components of the embodiment of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

In the description of the embodiments of the present utility model, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the utility model product is usually placed when in use. It is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

In the description of the embodiments of the present invention, "multiple" means at least 2.

In the description of the embodiments of the present utility model, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

Example:

The purpose of the utility model is to improve agricultural production efficiency, reduce labor costs, and reduce agricultural labor intensity, and to provide a wheat hoeing device with high efficiency and convenience.

A wheat hoeing device comprises a frame 1;

A suspension mechanism 2 for suspension connection to a tractor is fixedly provided at the front middle of the frame 1, and depth limiting wheels 3 for adjusting the hoeing depth are symmetrically connected to the inner walls of both sides thereof, and the depth limiting wheels 3 are fixedly provided on a rotatably adjustable threaded assembly 4;

The rear end of the frame 1 is provided with two rows of rake tooth columns 5 arranged in a front-to-back distribution, and a plurality of rake teeth 6 are arranged at equal intervals along the length direction of each row of rake tooth columns 5, and the front and rear rake teeth are arranged in a staggered manner;

The advantages of the utility model are:

By using the depth-limiting wheel, the hoeing depth can be precisely controlled, thereby achieving efficient and convenient working results; by using the threaded assembly, the depth-limiting wheel can be easily installed and disassembled, thereby improving the maintainability and service life of the equipment.

As shown in Figure 1-2,

A connecting rib 7 is fixedly provided between the upper rear side of the suspension frame on the suspension mechanism 2 and the rear end of the frame 1 to enhance the stability of the equipment structure;

The angle of the rake teeth 6 is bent backwards to 30 degrees, so that good soil cutting performance can be maintained during the tillage process, and at the same time, the rake teeth can be effectively prevented from hooking the wheat rhizomes and causing damage by pulling out.

The above describes the utility model and its implementation methods, which are not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
