Description

Combined soil preparation machine for subsoiling and crushing

technical field

The utility model belongs to an agricultural plowing and land preparation machine, in particular to a combined soil preparation machine for deep loosening and crushing.

Background technique

With the development of dry farming farming technology in our country, subsoiling and soil preparation compound farming technology has been widely promoted in some areas in northern my country. Subsoiling soil preparation equipment has also developed rapidly, and has become one of the main equipment in the protective tillage equipment system promoted in my country in recent years. Technically, many excellent technical solutions have been designed for the performance of compound subsoiling and soil preparation equipment. For example, a compound less-tillage land preparation machine used in the Heilongjiang reclamation area is generally designed as a large tractor-drawn type, including the main traction beam, front frame, rear frame, support wheels, subsoiling parts, crushing The soil part and the subsoiling part adopt a plate type subsoiling shovel with double wings, and the broken soil part adopts a disc harrow group. The technical solution effectively solves the technical problems of high operation speed, high efficiency and good soil preparation effect. However, there are still shortcomings: first, the operation resistance of the plate-type subsoiling shovel with two wings is large, and it must be equipped with a high-powered tractor; second, the frame is made of large-sized profiles, which is heavy and high in manufacturing costs; (up to 13m), turning maneuvers are inflexible, and cannot be adapted to small plot operations.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art, and provide a subsoiling and crushing combined soil preparation machine with small operation resistance, low manufacturing cost, flexible turning and strong adaptability.

In order to achieve the above object, the utility model adopts the following technical solutions: the utility model subsoil crushing combined soil preparation machine includes a frame, a depth-limiting wheel, and a subsoiling component. Two rows of subsoiling components are installed longitudinally under the front of the frame, and the two rows of subsoiling components are arranged in a staggered front and rear direction, located behind the rear row of subsoiling components, and the front crushing rake group and the rear crushing rake group are arranged in sequence. A rake group, and the front broken soil rake group and the rear broken soil rake group are installed on the frame in an offset configuration.

As the combined soil preparation machine for subsoiling and crushing of the utility model, the subsoiling part can be composed of a fixed seat, a shovel handle positioning pin, a hollow shovel handle, a nose bridge, and a subsoiling shovel tip. The hollow shovel handle is installed on the fixed seat through the shovel handle positioning pin. The front end of the hollow shovel handle is equipped with a subsoiling shovel tip, which is located above the subsoiling shovel tip. The front of the hollow shovel handle is provided with a nose bridge. Manufactured from rectangular tubes.

As the combined ground preparation machine for subsoiling and crushing of the utility model, the subsoiling part can also be composed of a fixed plate, a solid shovel handle, and a subsoiling shovel tip. The solid shovel handle is installed on the fixed plate, the front end of the solid shovel handle is equipped with a deep loose shovel tip, and the solid shovel handle is made of flat steel.

As a further improvement of the utility model's combined soil preparation machine for subsoiling and crushing, the subsoiling shovel tip is designed as a parallelogram row, with the long diagonal line of the parallelogram row as the axis, and the working faces on both sides of the subsoiling shovel tip are upward. Inclination, the inclination angle of the cutting edges at both ends of the subsoiling shovel tip is α, and the α angle is 40-50°.

After adopting the above-mentioned technical scheme, the beneficial effects of the combined soil preparation machine provided by the utility model are as follows:

1. Since the working surfaces on both sides of the subsoiling shovel tip are inclined upwards, and the inclination angle of the two ends of the subsoiling shovel tip is 40-50°, the subsoiling shovel tip is installed with the front end of the shovel handle to form an inclined working surface, and the soil loosening operation At this time, the soil produces lateral force on the subsoiling shovel tip, which makes the shovel handle vibrate, and the operation resistance in the subsoiling process is small.

2. Due to the simple structure and light weight of the deep loose parts, the frame can be directly designed as a suspension type, and the longitudinal size of the whole machine is small and light in weight. Therefore, the effects of low manufacturing cost and high flexibility and adaptability of turning manipulation are achieved.
