Embodiment 1

[0027] Such as figure 1 , figure 2 and image 3 As shown, the potato seedling weeding machine includes a positioning roller 1, a seedling pulling disc 3, a rotary tiller 5 and a "herringbone" shaped scraper 6, and the positioning roller 1 is set as a hollow cylinder structure, and the positioning roller The central axis of the roller 1 is provided with a pressing roller shaft 2, and two seedling pulling discs 3 are arranged at the position behind the bottom of the positioning pressing roller 1. 3. A plurality of cog teeth 7 are evenly inlaid along the outer edge of the circumference; a rotary tiller shaft 4 is arranged behind the disc 3 for pulling seedlings, and a rotary tiller 5 is arranged in a 360° ring on the outer walls of the two ends of the rotary tiller shaft 4 The rear of the rotary tiller shaft 4 is provided with a "herringbone" shaped scraper 6, and the center of the "herringbone" shaped scraper 6 is set against the midpoint of the rotary tiller shaft 4.

Embodiment 2

[0030] On the basis of Example 1, different from Example 1, such as figure 1 and figure 2 As shown, the potato seedling weeding machine includes a positioning pressure roller 1, a seedling pulling disc 3, a rotary tiller 5 and a "herringbone" shaped scraper 6, and the seedling pulling disc 3 is positioned along the axis of the positioning pressing roller 1 Set in parallel, and the diameters of the two turntables are the same, the sum of the diameters of the two seedling-pulling discs 3 is less than or equal to the length of the positioning roller 1, and the rotation directions of the two seedling-pulling discs 3 are opposite. The low-speed rotation mode in which the central axis rotates to the two outer sides. There is a gap between the seedling pulling disc 3 and the positioning pressure roller 1. The gap distance is set to be about 3 cm lower than the bottom of the positioning pressure roller 1. The blunt tooth Teeth 7 are set to a cylindrical rod structure, and the number...

Embodiment 3

[0032] On the basis of Example 1, different from Example 1, such as figure 1 and figure 2 As shown, the potato seedling weeding machine includes a positioning roller 1, a seedling pulling disc 3, a rotary tiller 5 and a "herringbone" shaped scraper 6, and the 5 rotary tillers are arranged in a 7-shaped curved knife structure, The 5 rotary tiller blades at the two ends of the rotary blade shaft 4 are installed respectively in the ridges on both sides of the double-row potato ridge, and the "herringbone" shaped scraper is set to be welded by the upper wing plate and the lower wing plate. The one-piece structure formed is arranged obliquely according to the slope of the double-row potato ridges, and its width is greater than the width of the rotary tiller shaft 4. The upper wing plate of the "herringbone" shaped scraper is set to be high at the front and low at the back and aligned with the horizontal plane. The parallelogram plate inclined at a certain angle, and the lower win...

Abstract

The invention discloses a potato seedling cutting and weeding machine. A compression roller shaft is arranged on a central axis of a positioning compression roller of a cylinder structure. Two seedling pull-out discs are arranged at the rear positions of the bottom of the positioning compression roller. The centers of the seedling pull-out discs are connected with gear boxes through rotation shafts. A plurality of blunt teeth are evenly embedded in the outer edges of the seedling pull-out discs along the circumference. A rotary blade shaft is arranged at the rear of the seedling pull-out discs, rotary blades are arranged on the outer sidewalls of both ends of the rotary blade shaft in a 360 DEG ring shape, and herringbone scraper plates are arranged at the rear ends of the rotary blade shaft. The potato seedling cutting and weeding machine achieves the function of pulling out and arranging potato stalks into the corresponding furrows and implements the cutting and removing of potato seedlings and weeds in the furrows; the potato seedling cutting and weeding machine can simultaneously complete the works of lifting of potato seedlings, allocation and position limiting of potato seedlings, and cutting of stalks, so that a subsequent potato harvester has reduced resistance, accelerated traveling speed and reduced failure rate, thus early preparations of removing seedlings and weedsfor subsequent potato grading and bagging are performed and the harvesting efficiency of potatoes can be improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and equipment, and in particular relates to a machine for weeding and killing seedlings of potatoes. Background technique [0002] In recent years, due to the strong growth momentum of consumption demand and industrial processing demand of potatoes, as well as the strong support of government policies, planting potatoes has become an important way to solve the food problem and increase farmers' income. According to statistics, in 2010, the world production of potatoes has reached 324.181889 tons, and China is the largest production country in the world, nearly 75 million tons. The main producing areas of potatoes in China are the Southwest Mountains, Northwest, Inner Mongolia and Northeast. In view of the current situation of large-scale planting of potatoes, it is difficult to carry out potato grading and bagging with the current harvesting method of potato seedling killing machin...
