Description

Technical Field

[0001] This utility model belongs to the field of agricultural seeding machinery technology, and in particular relates to a soil covering device for flat-ground seeding. Background Technology

[0002] Sowing is a very important part of agricultural production. The sowing process usually involves three steps: furrowing, sowing, and covering with soil. In today's world where mechanization and automation are very common, there are many types of seeders that can complete this operation. However, these seeders are usually used in large-scale agricultural production environments and are not suitable for small and medium-sized agricultural sowing. Summary of the Invention

[0003] This invention provides a device for sowing and covering soil on flat land to solve the problems mentioned in the background art.

[0004] The technical problem solved by this utility model is achieved by the following technical solution:

[0005] A flat-ground sowing and covering device includes a furrow opener, a leveling plate, crossbeams, a seeder, and a covering device. The furrow opener is installed on the leveling plate, and a pair of crossbeams are connected to the rear side of the leveling plate. The seeder is installed in the middle of the crossbeams, and the covering device is installed at the rear end of the crossbeams.

[0006] The furrow opener includes a cone head, a front mounting rod, and a crossbar. The cone head is located at the very front and bottom of the entire device. The top of the cone head connects to the front mounting rod, which connects upwards to the bottom of the seeder body. A crossbar extends rearwards from the middle of the front mounting rod and connects to a leveling plate. A crossbeam is connected to the rear of the leveling plate. The crossbeam consists of a pair of angle brackets. A rear mounting hole is cut at the rear end of the angle brackets, and a soil covering device is installed in the rear mounting hole. The rear part of the angle brackets connects upwards to a rear mounting rod, which connects upwards to the bottom of the seeder body.

[0007] The seeder is connected between a pair of angle members. The lower part of the seeder is a seeding tube, which connects upwards to a receiving groove. The receiving groove is open at the top and extends to both sides. The receiving groove receives seeds from the seeder body and sows them downwards, falling from the seeding tube into the newly opened furrow. The receiving groove and the seeding tube have a downward-through hole in the middle, serving as a channel for seed flow. The covering device is also an angle member structure, and there is a pair of covering devices. The covering devices are installed on the rear mounting hole and tilted inwards. In the upward-facing configuration, the amount of soil covering is relatively small, burying the seeds to a shallower depth. Conversely, in the upward-facing configuration, the amount of soil covering is relatively large, burying the seeds to a greater depth.

[0008] Furthermore, nuts are installed on the crossbar to adjust the height of the crossbar and the flat plate and to tighten them.

[0009] Furthermore, a waist-shaped hole is cut in the center of the leveling plate, through which a crossbar of the furrow opener is inserted. This allows adjustment of the distance between the conical head of the furrow opener and the bottom of the leveling plate, thus adjusting the furrow depth. As the seeper moves, the leveling plate smooths out the slight undulations in the land.

[0010] Furthermore, the entire leveling and soil-covering device described above is installed at the bottom of the seeder. The seeder has a pair of rollers, and the rollers are connected to a hopper via a rotating shaft. The hopper has multiple compartments, one of which is a seed box. Seeds are placed in the seed box and sieved by the seeder's sieving component before flowing into the receiving trough. The sieving component is located below the seed box and has sieving wheels at its bottom. The sieving wheels sieve the seeds in the seed box into a predetermined quantity and flow them into the seeder's receiving trough. Supports are located on both the front and rear sides of the bottom of the sieving component. A front mounting rod is mounted on the front support, and a pair of rear mounting rods are mounted on the rear support.

[0011] The beneficial effects of this utility model are:

[0012] This invention relates to a combined operation for leveling and covering soil on a seeder. It features an adjustable-depth furrowing cone, followed by a leveling plate for small-scale soil leveling, and then adjustable-spacing seed tubes that collect seeds from the seeder and guide them into the furrows. Finally, a suitable covering soil configuration can be selected as needed. Attached Figure Description

This embodiment mainly describes the components associated with the flat-ground sowing and soil-covering device.

[0019] In this embodiment, the connection of the various components uses welding technology extensively and bolt connection technology to a limited extent. For welding technology, weld seams are not shown in the drawings for the sake of simplicity, which is easily understood by those skilled in the art. For bolt connection parts, connection holes are used to illustrate the connection, and bolts are not shown in the drawings for the sake of simplicity, which is easily understood by those skilled in the art.

[0020] See Figures 1-3 The flat-ground sowing and covering device shown includes a furrow opener 10, a leveling plate 20, a crossbeam 30, a seeder 40, and a covering device 50. The furrow opener 10 is installed on the leveling plate 20. A pair of crossbeams 30 are connected to the rear side of the leveling plate 20. The seeder 40 is installed in the middle of the crossbeams 30, and the covering device 50 is installed at the rear end of the crossbeams 30.

[0021] The furrow opener 10 includes a cone head 11, a front mounting rod 12, a crossbar 13, and a nut 14. The cone head 11 is located at the front end and lower position of the entire device, and is used to open furrows with a narrow width and shallow depth in the soil. The top of the cone head 11 is connected to the front mounting rod 12, which is connected upward to the bottom of the seeder body. The crossbar 13 extends backward from the middle of the front mounting rod 12 and is connected to the leveling plate 20. The nut 14 is installed on the crossbar 13 to adjust the height of the crossbar 13 and the leveling plate 20 and to tighten them.

[0022] A waist-shaped hole 21 is opened in the middle of the leveling plate 20. The crossbar 13 of the furrow opener 10 is inserted into the waist-shaped hole 21, which can adjust the distance between the cone head 11 of the furrow opener 10 and the bottom of the leveling plate 20, that is, adjust the furrowing depth. The leveling plate 20 smooths the slight undulations of the land as the seeder moves.

[0023] The flattening plate 20 is connected to a crossbeam 30 on its rear side. The crossbeam 30 is composed of a pair of angle members 31, and the distance between the pair of angle members 31 is the width of the trench. A rear mounting hole 32 is cut out at the rear end of the angle member 31, and a soil covering device 50 is installed on the rear mounting hole 32. The rear part of the angle member 31 is connected upward to a rear mounting rod 33, which is connected upward to the bottom of the seeder body. That is to say, the flattening and soil covering device in this embodiment is connected to the bottom of the seeder body through a front mounting rod 12 and a pair of rear mounting rods 33.

[0024] The seeder 40 is connected between a pair of angle members 31. The lower part of the seeder 40 is a seeding tube 41, which connects upwards to a receiving groove 42. The receiving groove 42 is open at the top and extends to both sides. The receiving groove 42 receives seeds from the seeder body and sows them downwards, allowing them to fall from the seeding tube 41 into the newly opened furrow. The receiving groove 42 and the seeding tube 41 have a downward-through hole 43 in the middle, serving as a seed flow channel. The lateral extension of the receiving groove 42 allows the installation position of the seeder bottom to be adjusted laterally as needed. After multiple of these devices are installed at the bottom of the seeder and adjusted, the resulting seeding row spacing is determined.

[0025] The covering device 50 is an angled member structure, and there is a pair of covering devices 50. The covering devices 50 are installed on the rear mounting hole 32 and are inclined inward. Figure 2 The two soil covering devices 50 shown represent two installation configurations of this soil covering device, namely, the difference between the facing upwards and downwards of the corner piece. In practical applications, the appropriate configuration can be selected based on the needs. The upward-facing configuration uses relatively less soil, resulting in a shallower seed burial depth. Conversely, the upward-facing configuration uses relatively more soil, resulting in a deeper seed burial depth.

[0026] The entire flat-ground sowing and soil-covering device described above is installed at the bottom of the seeder. The seeder has a pair of rollers 100, and the rollers 100 are mounted on a hopper 200 via a rotating shaft 110. The hopper 200 has multiple compartments, one of which is a seed box 210. Seeds are put into the seed box 210 and are sieved by the seeder's sieving component 300 before flowing into the receiving trough 42. The sieving component 300 is located below the seed box 210, and its bottom has a sieving wheel 310. The sieving wheel 310 sieves the seeds in the seed box 210 according to a predetermined quantity and flows them into the receiving trough 42 of the seeder 40. The sieving component 300 has supports 320 on both the front and rear sides of its bottom. A front mounting rod 12 is mounted on the front support 320, and a pair of rear mounting rods 33 are mounted on the rear support 320.

[0027] The working principle of this utility model is: to attach... Figure 3The entire assembly shown is connected to a power source, which can be human power or other rolling power sources. The power source drives the entire seeder to move, at which time the rollers 100 and the shaft 110 rotate accordingly. Multiple leveling and soil-covering devices are installed at the bottom of the entire device, with a certain length that lies close to the ground, so that the hopper 200 and the sieving component 300 only move horizontally and do not rotate. Seeds to be sown are placed into the seed box 210, sieved by the sieving component 300, and flow into the seeder 40 via the sieving wheel 310.

[0028] As the seeder moves, the cone 11 at the foremost end creates furrows in the soil, and then seeds flow from the seeder 40 into the furrows. The covering device 50 is configured to scrape soil from its sides into the furrows as needed, completing the covering operation.

[0029] The above embodiments mainly illustrate the flat-land sowing and soil-covering device of this utility model. Although only a limited number of embodiments and technical features have been described, those skilled in the art should understand that this utility model can be implemented in many other forms without departing from its spirit and scope. Therefore, the illustrated embodiments are considered illustrative and not limiting, and this utility model may cover various modifications and substitutions without departing from the spirit and scope of this utility model as defined by the appended claims.
