Description

Technical Field

[0001] The utility model relates to the technical field of turning and drying rakes, in particular to a turning and drying rake for drying grains. Background Art

[0002] The earliest method of drying grains was manual drying, where people spread the grains on the ground or in a drying yard and dried them with natural wind and sunlight. As grain drying technology developed, people began to use simple manual turning tools. These tools were usually rakes made of wood or bamboo, and people used their hands to lift and turn the grains so that the grains could be dried evenly and faster.

[0003] Most of the existing turning and drying rakes have a wooden bottom surface connected to equidistant and equal-height nail rake blocks, and a handle is connected thereto; this turning and drying rake can only perform simple turning and drying of grains; however, the drying thickness of the grains needs to be adjusted according to their moisture content, and since the turning and drying rake of this structure is an integrated structure, the width of the turned and raked grains cannot be adjusted by this structure, and since the drying height of this turning and drying rake cannot be adjusted, when drying grains, the turning and drying operation cannot be performed on grains of different required drying thicknesses, which affects the drying effect of relatively moist grains; therefore, the above problems need to be improved.

The rotating assembly includes a guide groove opened in the middle of the top surface of the U-shaped plate 2, and a connecting rod 5 is vertically arranged inside the guide groove, through which the torsion block 4 and the transverse bevel gear 7 are conveniently connected; the lower end of the connecting rod 5 is fixedly connected to the transverse bevel gear 7, and the vertical bevel gear 8 is rotated by the transverse bevel gear 7; and vertical bevel gears 8 are arranged on both sides of the middle of the inner side of the U-shaped plate 2, through which the forward screw 9 and the reverse screw 10 are conveniently rotated; the vertical bevel gear 8 and the transverse bevel gear 7 are meshing transmission. The reverse screw 10 and the forward screw 9 are respectively arranged horizontally between the vertical bevel gear 8 and the outer baffle 12 and the inner baffle 11, and the inner side surfaces of the forward screw 9 and the reverse screw 10 are fixedly connected to the outer side surface of the vertical bevel gear 8, and the forward screw 9 and the reverse screw 10 are respectively threadedly connected to the inner baffle 11 and the outer baffle 12.

[0020] In the present invention, the upper end of the connecting rod 5 is fixedly connected to the inner side of the torsion block 4, and the lower end of the torsion block 4 is provided with a bearing 6, through which the connecting rod 5 is convenient to rotate; the outer side of the bearing 6 is fixedly connected to the inner side of the upper end of the guide groove, and the inner side of the bearing 6 is fixedly connected to the upper end of the connecting rod 5.
