Cultivator protection frame

Abstract

The invention discloses a plowing box protection frame which comprises a protection frame body (7) and plowing box protection plates (8) symmetrically arranged on the left side and the right side of the protection frame body (7). The protection frame body (7) comprises a first inclined plate (7a), a second inclined plate (7b) and a middle connecting plate (7c), the plowing box protection plates (8) are arranged on the rear lower portion of the protection frame body (7), the lower portions of the plowing box protection plates (8) are folded over to be in an L shape towards the outer side relative to the upper portions of the plowing box protection plates (8), the rear ends of the plowing box protection plates (8) are high, the front ends of the plowing box protection plates (8) are low, the front ends of the upper portions of the plowing box protection plates (8) are connected with the rear end of the first inclined plate (7a), and the rear ends of the upper portions of the plowing box protection plates (8) are connected with the lower end of the second inclined plate (7b). The plowing box protection frame is simple in structure and ingenious in concept, and effectively solves the problem that a rear wheel drives hard foreign matter to strike a plowing box body in the working process of a plowing box, the service life of the plowing box body is prolonged, and the operating comfort of a farming machine is improved.

Description

technical field [0001] The invention belongs to the technical field of farming machinery and equipment, and in particular relates to a protective frame suitable for a tiller box. Background technique [0002] The farming machine is mainly composed of a cultivating box and a walking box, combined with image 3 , Figure 4 As shown, the tillage box is usually composed of a tillage box 1, a tillage hexagonal shaft 2, a transmission gear shaft 3, a bevel gear 4, a rear end cover 5 of the tillage box and a side end cover 6 of the tillage box. The front end of the tillage box 1 has a flange 1a for being connected with the walking box. The bevel gear 4 is sleeved on the tillage hexagonal shaft 2, the bevel gear 4 is engaged with the transmission gear shaft 3 for transmission, and the rear wheel mounting sleeve 5a is provided on the rear end cover 5 of the tillage casing for rear wheel installation. When working, the spline sleeve of the walking box extends into the tillage box 1,...

AI Technical Summary

Problems solved by technology

[0003] During the working process, the rotation of the rear wheel can easily bring up hard foreign objects such as stones, which will hit the tillage box and reduce the service life of the tillage box. At the same time, the continuous impact sound will also affect the operating comfort of the farming machine.
