Description

Multi-seed spreading devices and seeders

technical field

The utility model relates to the technical field of agricultural mechanization, in particular to a multi-seed sowing device and a seeder.

Background technique

Seeder is a planting machine that uses crop seeds as the object of sowing. According to different sowing methods, seeders can be divided into the following types: spreaders, drills and hole seeders.

Among them, the seed drill is mainly used for the sowing of small seeds such as grains, vegetables, and pasture, and the commonly used seed drill is the grain seed drill. During operation, the walking wheel drives the seeding wheel to rotate, and the seeds are discharged from the seed cup in the seed box into the seeding pipe according to the required seeding amount, and fall into the opened groove through the opener, and then are pressed by the soil-covering device. Compact the seed cover. The crops sown by the drill are distributed in parallel and equidistant strips after emergence.

In the prior art, during the seeding process, the seeder can only sow one crop variety, and can only sow a row of crop seeds; and, during the seed sowing process, the soil is easily ejected and blocks the seeding tube of the seeder. , and the repeated cleaning of the seeding tube greatly reduces the efficiency of seeding.

Utility model content

The purpose of the utility model is to provide a variety of seed sowing device, which can simultaneously sow multiple crop seeds or multiple rows of crop seeds during the sowing process as required, and avoid soil blocking of the sowing pipeline to affect the sowing efficiency.

Another object of the present invention is to provide a seeding machine, which can improve the seeding efficiency and provide various seeding schemes.

The embodiment of the present utility model is realized in this way:

A multi-seed sowing device, which comprises a plurality of guide cylinders, the plurality of the guide cylinders are connected to each other, the outlets of the plurality of the guide cylinders are all oriented in the same direction; the inlets of the plurality of the guide cylinders are used for introducing seeds; and The mudguard is included; the mudguard is arranged on the outer side of the outlet of at least one of the guide cylinders.

The guide cylinders of the above-mentioned various seed sowing devices are used to spread seeds or fertilizers. The seed particles and/or fertilizer particles enter from the hopper through the inlet of the guide cylinder, and flow from the outlet to the soil groove under the guidance of the guide cylinder. The multiple guide cylinders are connected to each other, and their outlets face the same direction, so the multiple guide cylinders can simultaneously introduce a variety of crop seeds, or introduce different seeds and fertilizers, and spread them into the pre-excavated trenches. The mud plate can effectively prevent the soil from blocking the guide cylinder, solves the problem of easy blocking of seeding and fertilizer in the prior art, and improves the efficiency of seeding and fertilizing. In order to reduce the use of materials and simplify the production process, the guide cylinder with a relatively high opening position or the guide cylinder that is not easy to contact the soil at a specific position may not be installed with a fender.

In a preferred embodiment of the present invention, a plurality of the guide cylinders are straight cylinders. The technical effect is that the flow rate and flow of the straight cylinder are beneficial to control and adjustment, and prevent the self-blocking of the guide cylinder from occurring.

In a preferred embodiment of the present invention, the area of the fender is larger than the area of the cross section of the guide cylinder. Its technical effect is: if the area of the fender is smaller than the area of the cross section of the guide cylinder, it cannot block the soil splashed from the ground; if the area of the fender is equal to the area of the cross section of the guide cylinder, the use time is longer Afterwards, some mud is easily accumulated on the edge of the fender to block the outlet of the guide cylinder. By setting the area of the fender to be much larger than the area of the cross section, the above-mentioned risk of clogging the guide tube can be avoided.

In a preferred embodiment of the present invention, the axis of the outlet of the guide cylinder and the side surface of the fender facing the guide cylinder are arranged at an angle. The technical effect is: under the structural design condition, when the guide cylinder extends vertically to the ground, the fender is not placed horizontally, so the mud splashed on the fender can fall to the ground again by itself.

In a preferred embodiment of the present invention, at least one of the guide cylinders is provided with a blocking switch. The technical effect is as follows: after the guide cylinder is closed by the blocking switch, the sowing of one, more or even all seeds can be reduced as required, and the controllability of the seed sowing can be improved. It can also control the cyclic sowing of multiple types of seeds, so that multiple types of seeds can be spread in a groove at intervals.

In a preferred embodiment of the present invention, at least one of the guide cylinders is provided with a diameter adjustment switch. The technical effect is: by adjusting the diameter of the guide cylinder and changing the flow rate of the seeds, the density of the seeds planted in the soil can be changed.

A planter includes a plurality of hoppers and the above-mentioned various seed spreading devices, and an inlet of one of the guide cylinders is communicated with one of the hoppers.

In a preferred embodiment of the present invention, the inlet of the guide cylinder is communicated with the hopper through a hose, and the distance between the guide cylinder and the hopper can be adjusted. The technical effect is: according to the size and weight of the seed particles, the distance between the guide cylinder and the hopper can be changed, that is, the distance between the exit of the guide cylinder and the ground can be changed to meet the requirements of seed sowing.

In a preferred embodiment of the present invention, the number of the guide cylinders is two; the connecting line between the outlets of the two guide cylinders is perpendicular to the advancing direction of the planter. The technical effect is that the seeder with this structure can simultaneously sow two rows of seeds when two guide cylinders are simultaneously sowing, thereby improving the sowing efficiency. Further, the distance between the two guide cylinders can also be set to be changeable, thereby changing the planting spacing between the two rows of seeds.

In a preferred embodiment of the present invention, the number of the guide cylinders is two; the connecting line between the outlets of the two guide cylinders is parallel to the advancing direction of the planter. The technical effect is that the seeder with this structure can simultaneously sow two types of seeds in a row of grooves when the two guide cylinders are simultaneously sowing, thereby improving the sowing efficiency. Further, the blocking switch of the guide cylinder can be opened and closed rhythmically by the motor, so as to realize the interval planting of two types of seeds.

The beneficial effects of the present utility model are:

The multi-seed sowing device and the planter of the utility model are provided with a plurality of guide cylinders with the same outlet direction, which can simultaneously sow multiple types of seeds on the same piece of land, and can simultaneously sow seeds and fertilizers, and the mudguard can effectively prevent soil Blocking the guide cylinder solves the problem of easy blockage of seeding and fertilizer in the prior art, and improves the efficiency of seeding and fertilizer application.
