Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of agricultural machine plough head, and relates to a short knife type structure plough head used on a seeding machine. BACKGROUND

[0002] Agricultural machine refers to various mechanical equipment used in agricultural production, and the seeding machine is one of the agricultural machines. The seeding machine is a planting machine with crop seeds as the seeding object. The seeding machine can be installed with a plough head for operation. The existing plough head installed on the seeding machine is generally made of quenched steel. The plough head directly contacts the soil and loosens the surface soil. Although the soil is mostly soft, some hard soil and gravel are mixed in the soft soil. Since the existing plough head surface does not have a protection structure, long-time use and collision with the hard soil and gravel in the soil can easily cause damage and deformation. Moreover, the existing plough head has the problem of inconvenient disassembly during installation and maintenance, thereby reducing the work efficiency and assembly efficiency. Therefore, a short knife type structure plough head used on a seeding machine is designed to overcome the above problems. CONTENT OF THE UTILITY MODEL

[0003] The utility model aims at overcoming the deficiencies of the prior art and providing a short knife type structure plough head used on a seeding machine, which has a simple and reasonable structure, is convenient to install and disassemble, has a long service life, is firmly fixed, has high hardness and high wear resistance.

[0004] The utility model is implemented by the following technical scheme: a short knife type structure plough head used on a seeding machine, which comprises a plough head body in a short knife structure. The plough head body in the short knife structure is composed of a working part in a front sheet structure and a connecting part in a rear handle structure. The diameter of the working part is greater than that of the connecting part. When the connecting part is inserted into the seeding machine, the working part pushes against the seeding machine to perform plowing operation. Assembly holes and assembly grooves are formed on the connecting part, and a working head is formed on the working part.

[0005] As a preferred embodiment, an inclined guide edge is arranged above the tail of the connecting part, and an arc-shaped limiting edge is arranged below the tail. The guide edge is first inserted and guided, and the limiting edge is fixed to the edge inside the seeding machine after being inserted into the top. Assembly holes are formed on the side of the connecting part, and assembly grooves are formed below the assembly holes. The connecting part is assembled and fixed through the assembly holes and the assembly grooves.

[0006] As a preferred embodiment, the working part is composed of a working body and a working head. The tail of the working body is fixed to the connecting part, and the front of the working body is the working head. The working head and the working body are integrally curved upward to form a working back with an inner side on the upper side and a working edge with an outer side on the lower side. The diameter of one side of the working edge is smaller than that of the other side of the working edge. The working edge has an eight-shaped structure, and a plurality of hard alloy blocks or hard alloy particles are welded on the working edge.

[0007] Preferably, the working body is also provided with multiple mounting holes, which can be used to install other arc-shaped cutter heads to form a multi-cutter head structure.

[0008] Preferably, the mounting hole consists of a mounting through hole and a limiting hole. The limiting hole has a semi-circular structure and a circular structure, with the mounting through hole penetrating the working body in the middle.

[0009] The beneficial effects of this utility model are as follows:

[0010] The short-blade plowshare used on the seeder designed in this utility model has been changed from a purely cast plowshare to one covered with multiple high-strength, high-wear-resistant hard alloy blocks or hard alloy particles. This protects the plowshare body, greatly improves product lifespan and work efficiency, and reduces the need for plowshare installation and disassembly. The plowshare of this utility model is manufactured using a forging process, which significantly improves wear resistance compared to castings, while also allowing for more precise assembly dimensions. The connecting part of the blade handle structure is fixed with assembly holes and assembly slots, ensuring stable assembly and good firmness. This utility model has a reasonable structure, beautiful design, convenient installation and disassembly, high hardness, and high wear resistance, thereby greatly improving work efficiency.
