Seedling pulling up system of semi-automatic transplanting machine

Abstract

The invention discloses a seedling pulling system of a semi-automatic transplanting machine. Two ends of a seedling holding hand seat is movably connected with a seedling holding box body; the middle part of the seedling holding hand seat is connected with the end part of a handle, and the side edge of the handle is articulated with a first linkage plate through a lower pull rod; the seedling holding box body is internally and parallelly provided with two seedling holding hand shafts on which a seedling holding hand is mounted; both seedling hand shafts are respectively articulated with the first linkage plate; and an upper pull rod is arranged above the lower pull rod, one end of the upper pull rod is articulated with the first linkage plate through a second linkage plate, the other end of the upper pull rod is provided with a tooth poking block, a ratchet wheel matched with the tooth poking block is mounted on a ratchet shaft, a plurality of stop blocks are arranged along the direction of the length of the ratchet shaft, and fixed blocks matched with the stop blocks are mounted on a seedling disk frame. The seedling pulling system of a semi-automatic transplanting machine has simple structure, easy assembly, low cost and easy mounting, debugging and maintenance, and improves the efficiency of seedling pulling up and launching and the precision of transplanting while effectively reducing the burden of operators.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a seedling picking system for a semi-automatic transplanting machine. Background technique [0002] At present, there are two main methods of picking seedlings commonly used in transplanters: one is fully manual, and the other is fully automatic. The full manual method of picking seedlings is as follows: [0003] 1. The labor intensity is high when transplanting. The operator manually takes out the seedlings one by one from the seedling tray, and then puts them into the soil inserter or temporary turnover box, which requires a high degree of concentration of the operator, and the frequency of operation is quite fast, so the labor intensity is very high. [0004] 2. The transplanting efficiency is low. Because the seedlings are thrown manually, when the speed of the machine is increased, the movement speed of the burrower is correspondingly accelerate...

AI Technical Summary

Problems solved by technology

The operator manually takes out the seedlings one by one from the seedling tray, and then puts them into the soil inserter or temporary turnover box, which requires a high concentration of the operator's attention, and the frequency of operation should be quite fast, so the labor intensity is very high

[0004] 2. Low transplanting efficiency

Because the seedlings are thrown manually, when the speed of the machine is increased, the movement speed of the burrower is correspondingly accelerated, and the time for picking and throwing seedlings is shortened during manual operation. When the speed is increased to a certain level, the manual operation cannot keep up. The movement speed of the machine limits the speed of transplanting and the efficiency cannot be improved

[0005] 3. Low transplanting accuracy

The price of the hydraulic system is generally more expensive, which greatly increases the manufacturing cost

However, if the electronic system fails, it is difficult to detect and repair, which increases maintenance costs

[0008] 2. High installation and commissioning requirements

The fully automatic seedling picking mechanism involves relatively complex systems such as hydraulic systems and electronic systems. Before use, personnel with a certain technical level are required to install and debug, and at the same time, debugging personnel are required to adjust according to various situations during the specific use process. , it is difficult for users to adjust

[0009] 3. High requirements on the external environment

Due to the use of electronic systems and hydraulic systems, it is necessary to pay attention to temperature and dust-proof issues when storing the machine. In Xinjiang, the most developed agricultural mechanization area, there is a harsh environment with large temperature difference between day and night and large dust. The use and storage have extremely adverse effects
