This utility model discloses a konjac planter, relating to the field of agricultural machinery technology. The bottom of the konjac seed box is equipped with a ridging assembly for burying the konjac seeds, and the side is equipped with a planter assembly for evenly spreading the konjac seeds. The front end of the ridging assembly is equipped with a furrowing shovel for opening furrows and preparing the konjac planting bed surface. The rear end of the ridging assembly is sequentially equipped with a mulch film assembly and a soil covering tray for gathering soil and covering the mulch film. The upper end of the mulch film assembly is also equipped with a drip irrigation tape assembly for supporting the drip irrigation tape. This konjac planter can complete multiple functions of konjac planting in one operation, including furrowing, sowing, ridging, laying drip irrigation tape, mulching, and soil covering. The planter assembly drives the seed grid through a chain drive mechanism, and the transmission speed can be adjusted under the control of the speed regulator assembly to ensure that the konjac seeds are evenly spread according to a preset rhythm.

The application relates to the field of agricultural planting technology and discloses an agricultural planting soil loosening device, which comprises an outer shell, walking wheels rotatably arranged around the bottom of the outer shell, a soil loosening assembly arranged on one side of the inner part of the outer shell, a seeding assembly arranged at the middle of the top of the outer shell, and soil loosening wheels rotatably arranged horizontally and longitudinally in the inner part of the outer shell. The soil loosening assembly is arranged to move air to the top of the soil loosening wheels through the air guide pipe during soil loosening, so that the top surface of the soil loosening wheels is cleaned in an automatic and multidirectional manner, and the cleaning dead angle is reduced. The contact plate and the pressing rod and other components in the side pressing unit are matched, the contact plate is tightly pressed against the soil on both sides of the device, the soil loosening wheels are cleaned, the contact plate is always pressed against by the plurality of pressing rods, the device is kept in a horizontal state, the height deviation of the device on both sides is reduced, the soil loosening depths of the soil loosening wheels on both sides are kept the same, and the uniformity of soil loosening is improved.

The utility model relates to the technical field of soil leveling devices, in particular to a soil leveling device for land reclamation. Comprising a movable frame, a lifting support, a first mounting block, a rotating shaft, a rotating wheel, a rotating gear, a transmission toothed chain, a transmission gear, a leveling auger, a second mounting block, a protective shell, a material guide frame, a material guide hole, an intermittent shifting block, an adjusting block, a spring hinge, an adjusting plate, a material storage bin, a lifting assembly, a guide assembly, a soil loosening assembly and a leveling assembly. Leveling augers are arranged in the two sets of second mounting blocks, a spring hinge is arranged on the bottom wall of the material guiding frame, an adjusting plate is arranged on the side wall of the spring hinge, an adjusting block is arranged at one end of the spring hinge, and an intermittent shifting block is arranged on the side wall of the rotating shaft; in the using process of the soil leveling device, land leveling is achieved through the leveling auger, meanwhile, uniform sowing is achieved through the multiple sets of material guide holes, finally, scraping leveling is conducted through the leveling assembly, and the effects of efficient soil leveling and intermittent uniform sowing can be achieved.

The utility model belongs to the technical field of soybean planters, and particularly relates to a row-spacing-adjustable soybean planter which comprises a supporting frame, a supporting rod is fixedly connected between the two sides of the interior of the top end of the supporting frame, five sliding blocks are installed on the outer side of the supporting rod and matched with the supporting frame at equal intervals in a sliding mode, and a rack is installed on the inner wall of one side of the supporting frame. Mounting frames are mounted on the top sides of the sliding blocks, worm wheels and gears are mounted at the top ends and the bottom ends of the rotating shafts correspondingly, and worms are mounted on the outer sides of the rotating shafts; a controller sends an instruction to a servo motor, the servo motor is started, a rotating shaft at the output end of the servo motor drives a worm to rotate, a worm gear is meshed with the worm, the worm gear drives the rotating shaft, then a gear rotates, the gear is meshed with a rack on the inner wall of a supporting frame, a sliding block is driven to slide along a supporting rod, and the distance between a mounting frame and a bean outlet pipe is adjusted; due to the self-locking function of the worm gear and the worm, the sliding block cannot shift due to vibration after being fixed, and the accurate and stable row spacing is guaranteed.
