Straw uniformizing mechanism

Abstract

The invention relates to the technical field of planting machinery, in particular to a straw uniformizing mechanism. The straw uniformizing mechanism comprises uniformizing rods arranged on an outer passage wall of a discharging passage, the uniformizing rods are obliquely arranged while lower ends form straw outlets, shifting screw blades are arranged on the uniformizing rods, and a gap for clamping straw is formed between the shifting screw blades. The straw is guided out of the discharging passage and slides along the uniformizing rods, and the shifting screw blades on the uniformizing rodsare capable of smoothly realizing shifting of the straw to clamp the straw in gaps between the adjacent shifting screw blades and uniformizing rod bodies. In a rotating process of the uniformizing rods, the straw moves along the length direction of the uniformizing rods to realize transferring of the straw, straw guide-out quantity can be effectively controlled by controlling of rotating time andspeed of the uniformizing rods, and accordingly stable control of the straw guide-out quantity can be effectively realized, the straw can be guided into planting holes in a basically quantitative manner, and the yam survival rate is increased.

technical field [0001] The invention relates to the technical field of planting machinery, in particular to a straw equalizing mechanism. Background technique [0002] In recent years, in order to increase the yield of yam, many places adopt the method of drilling yams for planting. After the yam planting land is turned over and fertilized, the planting holes are dug out with spiral drilling equipment or shovels, and the planting holes are pressed against the length of the planting land. and the width direction are equidistantly spaced, so that the distance between adjacent planting holes is about 80cm. In order to improve the survival rate of yam, rice straw is generally filled in the planting holes, and then a hole is filled in the planting holes filled with rice straw. layer of base soil, and then import the yam planting segment into the base soil of the planting hole, and then fill the planting hole with soil; when importing the above-mentioned straw straw, in order to e...

[0002] In recent years, in order to increase the yield of yam, many places adopt the method of drilling yams for planting. After the yam planting land is turned over and fertilized, the planting holes are dug out with spiral drilling equipment or shovels, and the planting holes are pressed against the length of the planting land. and the width direction are equidistantly spaced, so that the distance between adjacent planting holes is about 80cm. In order to improve the survival rate of yam, rice straw is generally filled in the planting holes, and then a hole is filled in the planting holes filled with rice straw. layer of base soil, and then import the yam planting segment into the base soil of the planting hole, and then fill the planting hole with soil; when importing the above-mentioned straw straw, in order to ensure that the straw can be evenly distributed in the planting hole, the straw is generally folded in half The straw and yam planting segments in the prior art and the attached drawings are all carried out manually after being imported into the planting hole. The method of artificially introducing rice straw is not only inefficient, but also cannot ensure that the straw is evenly filled in the planting hole, thereby It has an impact on the survival rate of the yam planting segment, and the introduction of the above yam planting segment into the planting hole is also carried out manually, so the labor intensity of the entire yam planting is extremely high
