Embodiment Construction

[0008] As shown in the figure: select a high-quality steel plate 1 with a thickness of 1cm, a length of 2.5m, and a width of 1.3m, and weld the prismatic rake teeth 2 on the selected 1 according to a rhombus distribution, and curl the steel plate 1 after welding the prismatic rake teeth 2 Become a drum, make circular steel plates 5 at both ends of the drum, drive shaft 3 is set at the center of the circular steel plate 5, the bottom of the drive shaft 3 is provided with a weight switch 4, and the circular steel plate 5 is welded on the drum to make it closed.

[0009] Through the transmission shaft 3, the drum-type heavy harrow is connected to power equipment such as tractors and rotary tillers,

[0010] The net weight of the heavy rake is about 600 kg, and the weight of the rake can reach more than 1000 kg by adding water or sand through the weight switch 4.

[0011] The invention is suitable for compaction and flattening of various soils after plowing, especially for loam so...

Abstract

The invention provides a drum-type heavy rake which is characterized in that a high-quality steel plate being 1cm thick, 2.5m long and 1.3m wide is selected, wherein prismatic shaped rake teeth are welded and distributed on the selected steel plate in a rhombus form; the steel plate after being welded with the rake teeth is crimped into a drum; circular steel plates at the two ends of the drum are manufactured; a driving shaft is arranged at the center of the circular steel plates; a weight adjusting switch is arranged on the lower part of the driving shaft; the circular steel plates are welded on the drum, so as to close the drum. Through the arrangement, the drum-type heavy rake is fit for the compaction and flattening of various soils, especially, the loam and clay loam, after ploughing; the soil block can be crushed; the soil gap is small; the soil moisture retention is benefited; the survival rates of the vegetables, green soy beans and spinach seedlings are respectively increased by 36%, 28% and 21%; the effect is obvious.

Description

technical field [0001] The invention relates to the field of farmland cultivation, in particular to a drum type heavy harrow. Background technique [0002] After the soil is plowed, the soil is loose and the gaps are too large, resulting in moisture loss and low survival rate of seedlings. Contents of the invention [0003] The invention proposes a drum-type heavy rake, which is characterized in that: select a high-quality steel plate with a thickness of 1cm, a length of 2.5m, and a width of 1.3m, and weld the prismatic rake teeth on the selected steel plate according to a rhombus distribution. The steel plate is curled into a drum, and the circular steel plates at both ends of the drum are made, and the transmission shaft is set in the center of the circular steel plate, and the weight switch is set at the lower part of the transmission shaft, and the circular steel plate is welded on the drum to make it closed. [0004] Through the above settings, the present invention ...
