Description
Technical Field
The utility model relates to the field of machinery, in particular to a grid-shaped drum-type conveying mechanism for a seedling throwing machine.
Background
The rice seedling throwing technology is the best cultivation technology at present, and solves the problems of seedling damage and growth period prolongation of the traditional rice transplanting to a certain extent. The main advantages are that: the labor intensity of manual operation is low, the operation efficiency is high, the green turning is fast, the effective tillering at the low node is more, the spike shape is regular, the maturity is good, the yield increasing effect is obvious, but at present, almost no mature machine type is applied to production.
At present, the operation principle of the Japanese rice seedling throwing technology adopts a push-out type seedling taking principle, seedlings are planted into a field through a planting disc, and the Japanese rice seedling throwing technology has the following defects: the cost of the seedling raising tray is too high, 15 yuan per seedling raising tray, the mu dosage is 40-50 trays, the structure of the machine is complex, the working efficiency is low, the cost of the machine is high, and the total investment is high. The throwing disc type seedling throwing machine utilizes the high-speed rotation of the throwing disc to throw out the seedlings fed into the throwing disc, and the seedlings fall into a field by means of gravity and inertia to complete the planting operation. The air-blowing type seedling throwing machine utilizes high-speed air flow to throw seedlings into the field, and the seedlings are buried by gravity to complete planting operation. The air-blowing type seedling throwing machine and the throwing disc type seedling throwing machine have the following defects: uneven throwing and planting, difficult control of density and inconvenience for subsequent operation. The ordered rice seedling throwing machine is characterized in that a belt clamping type seedling taking mode is adopted, seedlings are pulled out from a seedling raising tray 3 and conveyed to each row through a belt, and when the seedlings reach the top end of the belt, the seedlings fall into a field after being thrown out, and planting operation is completed: the operation speed is fast, can realize throwing the seedling in line in order, but supplementary recruitment is many, and overall efficiency is not high, and is high to growing seedlings and soil preparation quality requirement, receives the strong wind to influence seriously. The key point is how to facilitate the subsequent seedling pulling operation of the seedling conveying mechanism, so that the development of a conveying mechanism for the seedling throwing machine, which has small damage to a seedling tray and seedlings, high seedling pulling efficiency and high-speed and accurate planting operation, is urgently needed.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides a grid-shaped drum-type conveying mechanism for a seedling throwing machine, which solves the problems of accurate positioning and accurate conveying of a seedling tray, ensures the accuracy of seedling supply, has small damage to the seedling tray and seedlings, has high seedling pulling efficiency, and is used for high-speed and accurate planting operation.
In one aspect, the utility model provides a grid-shaped drum type conveying mechanism for a seedling throwing machine, which comprises a front drum, a rear drum and a grid-shaped chain, wherein the grid-shaped chain is wound on the front drum and the rear drum, and grid rods are arranged on the grid-shaped chain at regular intervals.
In a further technical scheme, the diameter of the front roller is smaller than that of the rear roller, a tray is arranged below the grid-shaped chain on the upper layer, the tray is obliquely arranged, and a seedling tray storage rack is arranged below the grid-shaped chain on the lower layer.
In a further technical scheme, a seedling tray is placed on the grid-shaped chain on the upper layer and is made of soft plastic, the grid-shaped chain drives the seedling tray to move, and when the seedling tray moves to the grid-shaped chain on the lower layer, the seedling tray automatically falls into a seedling tray storage rack.
Compared with the prior art, the grid-shaped drum type conveying mechanism for the seedling throwing machine has the beneficial effects that:
has the advantages of simple structure, light weight, low processing and manufacturing cost, convenient operation, reliable work, little damage to the seedling tray and the seedlings, high production efficiency, good operation quality and the like. Solves the problems of accurate positioning and accurate conveying of the seedling tray and ensures the accuracy of seedling supply.

Detailed Description
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
As shown in figures 1 and 2, the utility model preferably discloses a grid-shaped roller type conveying mechanism 20 for a seedling throwing machine, the grid-shaped roller type conveying mechanism 20 is arranged on the seedling throwing machine 1 and comprises a front roller 200, a rear roller 201 and a grid-shaped chain 202, the grid-shaped chain 202 is wound on the front roller 200 and the rear roller 201, and grid rods 204 are arranged on the grid-shaped chain 202 at intervals. The diameter of the front roller 200 is smaller than that of the rear roller 201, a tray 203 is arranged below the upper layer grid-shaped chain 202, the tray 203 is obliquely arranged, and a seedling tray storage rack 11 is arranged below the lower layer grid-shaped chain 202. The seedling tray 3 is placed on the upper layer grid-shaped chain 202, the grid rods 204 on the grid-shaped chain 202 drive the seedling tray 3 to move towards the rear roller 201, and when the seedling tray 3 moves to the lower layer grid-shaped chain 202, the seedling tray 3 automatically drops into the seedling tray storage rack 11. The seedling tray 3 is made of soft plastic, the seedling tray 3 can be bent, the seedling tray 3 is wound on the rear roller 201, the seedling tray 3 is bent, seedlings are loosened, the subsequent seedling pulling operation is facilitated, and the seedling tray 3 and the seedlings are slightly damaged, high in production efficiency, good in operation quality and the like.
