Folding type spike-tooth harrow

Abstract

The invention discloses a folding type spike-tooth harrow, including a main rod. The right side of a first harrow body is connected with a third harrow body through a hinge. The left side of a second harrow body is provided with a retaining member. The right side of a third harrow body is provided with a positioning member matched with the retaining member. The top ends of the second harrow body and the third harrow body are provided with clamping grooves. One end of a strut is provided with a clamping piece matched with the clamping groove. The other end of the strut is provided with a sliding block matched with a sliding groove. The sliding block is provided with a fastener hole. The sliding block and the main rod are cooperated through the fastener hole and vias and are movably connected through a lock bolt. Two sides of the sliding groove are provided with the vias matched with the fastener hole. The bottom ends of the first harrow body, the second harrow body, and the third harrow body are provided with spike teeth. The folding type spike-tooth harrow can be freely adjusted according to different parcels, and the spike-tooth harrows do not need to be changed. The spike-tooth harrow is convenient to use and simple to operate.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a foldable spiked rake. Background technique [0002] The spike-toothed harrow is an agricultural machine used to refine the soil on the farmland surface. In the process of agricultural production, the thinned soil is helpful for the germination and growth of crops. The traditional spiked-toothed harrow is used in daily farm work. Spike-toothed harrows are often used to refine the soil to create a good growth environment for crops. In this way, not only a separate spike-toothed harrow is required for different plots, but also the range of land refinement is fixed, which is It has caused considerable limitations. When faced with different plots, the size of the spiked harrow is often not suitable, and the corresponding spiked harrow needs to be replaced, which wastes time and labor in the production process, and the operation is troublesome. The size of the land ne...

Spike-toothed harrows are often used to refine the soil to create a good growth environment for crops.

When faced with different plots, the size of the spiked harrow is often not suitable, and the corresponding spiked harrow needs to be replaced, which wastes time and labor in the production process, and the operation is troublesome. The size of the land needs to be adjusted, which increases the operating cost and cumbersome operation procedures, and when the machine is not working, the machine takes up a lot of space during normal walking, which is easy to affect the surrounding environment, occupies the road area, and makes walking difficult. Convenience, but also hinder other passing pedestrians and vehicles
