Description

Rice seedling raising and seedling raising machine

technical field

The utility model relates to the technical field of agricultural machinery, in particular to a rice seedling raising and raising machine for replacing manual work.

Background technique

Rice planting is a labor-intensive industry. The traditional manual cultivation method is not only labor-intensive and time-consuming, but also labor-intensive, requiring a lot of labor for intensive cultivation.

With the development of agricultural production technology, rice planting methods have also been greatly improved. At present, in addition to traditional manual farming methods, there are also some mechanized farming methods in rice cultivation, but overall, the level of mechanization and technology is relatively low Low.

Regardless of manual cultivation or mechanical cultivation, the entire rice planting process still does not lose the following steps: sowing - raising seedlings - transplanting (transplanting) - field management (irrigation, weeding, disease prevention, pest control) - harvesting.

There are three main methods of operation in the above transplanting steps, namely manual transplanting, mechanical transplanting and throwing:

Artificial transplanting is achieved through artificial seedling raising, pulling out seedlings and artificial transplanting;

Mechanical transplanting is to cover the fine soil in a special plastic seedling tray, then sow, transport the seedling tray to the seedling field, then water and lift the tray, and install the transplanter after the seedlings grow, and finally realize mechanical transplanting in the field;

Seedling throwing technology requires plastic seedling trays with bowl holes. Seedling raising goes through the processes of laying seedling trays, covering with fine soil, artificial sowing, re-covering with fine soil, watering, raising the seedling trays, and taking seedlings, and then throwing them in the field.

These three rice transplanting techniques have the disadvantages of labor intensive, high fuel consumption, and high cost:

Among them, manual transplanting requires farmers to bend their backs to raise seedlings, pull out seedlings and transplant rice seedlings, which is labor-intensive and low in work efficiency.

Mechanical transplanting requires expensive special plastic seedling trays. Manually move the seedling trays and fill them with fine soil, then sow the seeds, transport the seedling trays, and then water, lift the trays, install the rice transplanter, and finally realize mechanical transplanting in the field. The weight of the rice transplanter is relatively large, and there are many rice fields that cannot be entered. Even if it is entered, there will often be missing or re-planting at the corners of the field and on the edge of the field. Mechanical transplanting requires a lot of labor, low efficiency, high fuel consumption and high cost.

Although seedling throwing no longer requires a transplanter, it requires a plastic seedling tray with bowl holes. Seedling raising requires the process of laying seedling trays, covering with fine soil, manual sowing, re-covering with fine soil, watering, raising the seedling tray, and picking seedlings. Labor is much and loaded down with trivial details, bother, and the cost of plastic seedling tray is high and pollutes the environment, and cost is also very high.

Therefore, how to design a kind of rice seedling raising and seedling raising machine with higher degree of mechanization is a technical problem that those skilled in the art need to solve at present.

Device 11, the seedling separator 11 among the figure is a schematic diagram, to clearly show its position.

The seedling separating device 11 comprises the seedling separating wheel and the elongated nail-toothed rake installed thereon, and the elongated nail-toothed rake does reciprocating circular motion under the drive of the seedling separating wheel.

Certainly, the concrete structure of seedling separator 11 is not limited to this, can also adopt other structural forms, for example: seedling separator can be made up of vertical cutter and cam, and cutter is supported by elastic member (such as spring), and its upper end Abutting against the outer peripheral surface of the cam, when the cam rotates, the cutter can be pushed downward at a certain frequency, thereby cutting the seedlings with soil. Since there are many ways of possible realization, it is not necessary to give examples one by one here.

The specific working principle of above-mentioned rice seedling raising and seedling raising machine is described below:

When carrying out seedling raising (sowing) operations: the rice seedling raising machine and the seedling lifter move forward in the bottom field of the seedlings. Firstly, the shovel 5 at the front will level the seedling raising surface prepared in the early stage, and then the driving wheel 3 will rotate at a high speed The crushing wheel 8 of the top soil is broken, thinned, and leveled, and simultaneously forms a drainage ditch on both sides of the furrow surface.

The bar-shaped seeding device 6 can be higher than the leveling device 0 to 5 centimeters, and this height difference depends on the situation of the rice seedling bottom field. The rice seedling bottom field is a dry field or the flatness is high, and this height difference can be relatively small. The bottom field is a mud field or the flatness is low, and the height difference can be relatively large.

Immediately sow after leveling the furrow surface, put the selected seeds into the hopper 7-1, the opening of the hopper 7-1 is downward, and the opening is accepted by the conveyor belt 7-2, and the conveyor belt 7-2 is driven by the belt pulley. Front rotation, belt pulley and the power wheel of power unit 2 are connected by V-belt or chain transmission, and the rotating speed is proportional to the forward speed of the whole machine, and the seeds are output by conveyor belt 7-2 for sowing.

The seeds are transferred out and sown with the conveyor belt 7-2, and they are not scattered on the furrow surface, but distributed in strips, so that the seeds are uniformly distributed in strips after emergence. It is realized by a set of grid-shaped seed dividers 6 with adjustable height and spacing. The seeds fall into the grid-shaped seed dividers 6, and fall on the furrow surface from the gap between the grid plates 6-2, and are distributed in strips .

In order to prevent mechanical vibration from making the seed distribution chaotic, the blade 6-3 about 5 to 8 centimeters long is provided with the blade 6-3 of about 5 to 8 centimeters below the grid plate of the grid-shaped seed divider 6 to go deep into the soil, so that the fixed grid-strip seed divider 6 prevents it from left and right. The effect of swinging, meanwhile, blade 6-3 also is the key part that uses when dividing rice shoot into strip when being used for raising seedlings later.

After the seeds are sown into the grid-shaped seed divider 6, the sowing is completed, and the grid-shaped seed divider 6 moves forward with the complete machine, and the sowing also continues to move forward with the complete machine to realize continuous operation.

Guide wheel 4 is installed on the both sides of frame 1 rear portion, close to the furrow surface that has been sown without rolling, plays a role in supporting the whole machine and guiding. Steering wheel 12 and driver's seat 13 are installed on the frame 1, so that Driver controls. Of course, for small equipment, the driver's seat 13 can also be omitted in order to reduce the volume.

After the above sowing work is completed, through the procedures of water application, film covering, chemical removal, and drought management, the transplantable seedlings can be grown in about 10 days, and can be transplanted when the seedlings are 10 days to 45 days old. plant. This has changed the shortcomings of mechanical transplanting and floppy disk throwing, which can only be transplanted and thrown at the age of 18 to 25 days. Larger room to grow.

When carrying out seedling lifting operations: first, remove the crushing wheel 8, then disassemble the conveyor belt 7-2 of the seeder, install it on the rear side of the grid-shaped seed divider 6 through bolts, and then disassemble the blade 5 Get down and be installed between the grid-like sorting device 6 and the conveyor belt 7-2, and be connected with the grid-like sorting device 6 by bolts.

The fuselage is turned 180 degrees to change the direction of travel, so that the two guide wheels 4 and the grid-shaped seed divider 6 are located at the front end of the fuselage. The function of dividing the seedlings into strips, and then shoveling the seedlings. At this moment, grid strip-shaped seed divider 6 is close to the ground, so that the seedlings are divided into strips, and the depth of control spatula 5 is at 3-6cm (according to the age of seedlings, small seedlings can be shallow, and large seedlings can be deep), conveyed by conveyor belt 7-2 Drive the seedlings to move backward.

After the rice shoots were moved out of the conveyor belt 7-2, the rice shoots that had been divided into strips were divided into small pieces again by the seedling separator 11, and fell into the seedling collection bucket 10, and the seedling separator 11 was connected with the power unit 2 by a triangle belt or a chain. The forward speed is proportional to ensure that the size of each small seedling is uniform. So far, the soil-bearing seedlings have been divided into small pieces that can be thrown and planted, and the seedling lifting work is completed, and they can be thrown and planted in the field.

The above-mentioned power unit 2 can specifically adopt a diesel engine, a gasoline engine, a motor with a power supply or a battery motor.

The rice seedling raising and seedling raising machine provided by the utility model have been introduced in detail above. In this paper, specific examples are used to illustrate the principle and implementation of the present utility model, and the descriptions of the above embodiments are only used to help understand the core idea of the present utility model.
