A furrow opener is mounted at the rear end of the ridging device, and the grooved wheel seed metering device goes deep into the lower part of the rack and is positioned at the rear end of the furrow opener; the soil covering device is arranged at the lower part of the rack at the rear end of the grooved wheel seed metering device, and the film covering device, the film pressing device and the hilling device are sequentially arranged at the lower part of the rack at the rear end of the soil covering device. The integrated pennisetum hydridum planting device can achieve integration of pennisetum hydridum planting, greatly improves planting efficiency, reduces manual labor intensity and cost, and brings economic benefits to producers. Compared with manual seeding, mechanical seeding can save time and manpower resources, increase the seeding rate and improve the seeding precision.

The invention relates to the technical field of rice sowing, and discloses an automatic uniform seed dropping device and method for rice planting. The device and method comprise a shell, wherein a feed port is provided at the top of the shell, a feed trough is provided at the top of the shell, and baffles are slidably connected to the left and right sides of the feed trough. The device and method for automatic uniform seed dropping for rice planting control the switch of the feed trough by the weight of seeds accumulated at the top of a trigger plate, so that seeds are automatically replenished when there are fewer seeds, thereby avoiding a reduction in the sowing rate due to lack of timely replenishment. When too many seeds are accumulated, the feed trough is automatically closed, thereby avoiding a reduction in the speed of seeds passing through the shell due to the accumulation of seeds at the top of the trigger plate. At the same time, when the trigger plate moves, the semi-gear drives the impact block to impact the inner plate, so that the trigger plate vibrates, thereby accelerating the speed of seeds passing through the through hole. Seeds can be sown periodically, and the sowing rate increases with the increase in the rotation speed of the shaft, thereby achieving the effect of equidistant sowing.

The invention relates to the technical field of vegetable planting, in particular to a dibbling type seeding machine for vegetable planting. Comprising a first numerical control base, second numerical control bases are arranged on the two sides of the first numerical control base, the upper sides of the first numerical control base and the two second numerical control bases are jointly and fixedly connected with symmetrically-distributed L-shaped plates, and a linearly-distributed conveying belt is arranged between the symmetrically-distributed L-shaped plates; a feeding frame is fixedly connected to the upper sides of the L-shaped plates which are symmetrically distributed, a groove is formed in the middle of the seeder, an electric rotating shaft is mounted on the feeding frame, a conveying roller is fixedly connected to the electric rotating shaft, and two groups of bulldozing plates which are distributed in a central symmetry manner are fixedly connected to the conveying roller. According to the device, the amount of pushed soil is changed through the bulldozing plates with different heights on the material conveying roller, and meanwhile, the mode of vibrating and shielding the soil is adopted, so that the extruded soil becomes loose, it is ensured that the soil thrown into holes by the feeding frame is more uniform, and normal growth of seeds is ensured.

The present invention belongs to the technical field of tilling machines, and specifically is an automatic tilling machine, comprising a frame, a hydraulic cylinder being hinged at the front end of the frame, a manure box, a protective cover, and a sowing mechanism being fixedly installed on the frame in sequence, a rolling roller being rotatably installed at the rear end of the frame, a discharging roller being rotatably installed in the manure box, a rotary tilling roller being rotatably installed in the protective cover, pulleys being fixedly installed at one end of the discharging roller and the rotary tilling roller, and synchronous belts being coiled on the two sets of pulleys. Since a plurality of groups of discharge troughs on the feed disc are distributed at intervals, as the feed disc rotates, a plurality of groups of discharge troughs allow corn seeds to fall into triangular pieces at intervals, so that the corn seeds sown on the land are distributed at intervals, so that there is enough space for plant growth. Secondly, corn seeds are larger in volume than seeds of intensive crops such as wheat, and a plurality of groups of wheat seeds can be contained in the discharge trough at one time, so that the device can also sow seeds of intensive crops such as wheat, thereby improving the practicability of the device.

The application provides an air suction type seed sowing device and relates to the technical field of agricultural machinery. The air suction type seed sowing device comprises a front cover and a rear cover, the front cover and the rear cover are used to form an air suction space, the air suction space is provided with an air suction rotating disc which is installed in a rotating mode and is close to the rear cover, a semicircular stretching rubber film is glued to the inner wall of an air suction hole far from a stretching patch, when the semicircular fixed pieces on both sides are mutually adhered to form the minimum spacing, the semicircular fixed pieces on both sides move away from each other, a rhombus-like air suction gap is formed between the stretching patches which are symmetrically arranged on both sides, the size of the air suction gap between the stretching patches is adjusted through the translational motion of the semicircular fixed pieces, the elastic stretching of the flexible rubber film greatly simplifies the structure, a flush air suction surface can be formed on the air suction rotating disc, which is more conducive to the smooth separation in the subsequent steps, the sowing rate is improved, and the air gap adjustment range is larger, so that the air suction type seed sowing device can adapt to the smooth sowing of soybean seeds with various sizes.
