Novel hand-held chemical fertilizer spreading device

Abstract

The invention discloses a novel hand-held chemical fertilizer spreading device, which comprises a supporting frame, wherein a storage groove is formed in the upper end of the supporting frame; a handrail is arranged at the rear end of the supporting frame; a first rotating rod is connected to the lower end of the supporting frame in a rotary manner; rotary wheels are fixedly connected to both endsof the first rotating rod; a plurality of supporting columns are arranged at the lower end of the supporting frame; and the other end of each the supporting columns is fixedly connected to the upperend surface of a supporting plate, so that when chemical fertilizers are spread, the chemical fertilizers can be spread into soil layers. By additional arrangement of a soil leveling device, after thechemical fertilizers are spread, the soil layers can be turned over by the arrangement of the soil leveling device, and thus the chemical fertilizers are covered under the soil layers, so that volatilization of the chemical fertilizers can be effectively avoided, and the utilization rate of the chemical fertilizers is improved; and meanwhile, limited components are additionally arranged, and thusthe spreading regularity of the chemical fertilizers can be ensured, and the uniformity of the spreading amount of the chemical fertilizers can be ensured, so that the effect of avoiding waste can beachieved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a novel walk-behind chemical fertilizer spreading device. Background technique [0002] Agricultural machinery refers to various machinery used in crop planting and animal husbandry production, as well as in the primary processing and handling of agricultural and animal products. [0003] The patent application with the notification number CN207897338U discloses an agricultural machinery fertilizer device, which consists of the following structures: adjustment controller, fasteners, support plate, adjustment confinement screw, connection screw hole, support transmission Tubes, fastening rings, support swivels, grips, tie rods, support frames, travel wheels, loosening harrow heads, sensors, rotary spreaders, motors, oil tanks and discharge ports. The beneficial effect of the present invention is that by being provided with an adjustment controller, firstly, the con...

Problems solved by technology

[0004] However, the following defects still exist in this patent: (1) the equipment is not provided with a soil turning and leveling device, so that chemical fertilizers can only be spread on the surface of the soil layer, which is easy to cause the volatilization of chemical fertilizers, resulting in a reduction in fertilizer efficiency; (2) as everyone knows, a Granular chemical fertilizer can play a role within a certain range. Therefore, if the same piece of land is sown with excessive chemical fertilizer, it will cause excess nutrition, which will cause damage to crops. In this patent, there is no adjustment device, so it is impossible to control the chemical fertilizer. spreading rate
