Background technique

At present, with the continuous expansion of forest and fruit planting area, the demand for forest and fruit planting mechanization has become increasingly prominent. However, the mechanization of production in the forest and fruit industry, especially the mechanization of ditching and fertilization in orchards, is still very low. When fertilizing in an orchard, not only the growth characteristics and seasonal characteristics of the corresponding fruit trees should be considered, but also the depth of fertilization should be paid more attention to. Therefore, according to agronomic requirements, deep fertilization can not only improve fertilizer efficiency and save fertilizer, but also promote the downward growth of crop roots, which is beneficial to enhance the ability of fruit trees to resist drought and lodging. In terms of fruit tree management, ditching and fertilization are a lot of work and labor-intensive work. Traditional fertilization methods, especially when applying organic fertilizers, need to dig ditches or pits on both sides of each fruit tree and in the layer where the root system is concentrated to distribute fertilizer. The production rate is not high, and there is an urgent need to replace heavy manual labor with mechanization. The methods of deep fertilization in foreign orchards mainly include: the general application method of the whole garden, which can be operated by a subsoiler; the circular fertilization method, which can be operated by a digging machine; , Digging machine can be used for operation; furrow fertilization method, this method is suitable for more regular orchards, and orchard ditching machine is used for operation.

Ditching and fertilization in orchards is generally done by using a ditching machine along the direction of the fruit trees in the orchard, and opening a long ditch with a depth and width of 40-50 mm in each row, and then fertilizing and covering soil manually. At present, there is a 1KL-100 type vertical spiral ditching machine designed and completed by Northeast Agricultural University Han Yongjun and others as the mechanical device for ditching. The 1KGA-300 orchard ditching machine is composed of a frame, a soil throwing baffle bracket, a bearing seat assembly, a screw, an adjusting tail wheel assembly, and a soil throwing baffle assembly. The working parts are horizontal cone and spiral type, and the tractor hydraulic suspension is adopted. The power is transmitted from the power output shaft of the tractor to drive the working parts to rotate, thus completing the ditching operation. The screw adopts an offset method, the depth of the ditch can be adjusted by adjusting the tail wheel assembly, and the thrown soil baffle assembly can make the thrown soil fall back near the fertilizer ditch, which is convenient for back burying. This machine mainly meets the ditching needs of medium row spacing and dwarf densely planted orchards. The small chain knife trencher jointly developed by the China Agricultural Machinery Research Institute and Shandong Guangrao Sanyuan Hydraulic Co., Ltd. cuts the soil in continuous rotation by fixing wear-resistant carbide blades on the excavation chain, and brings the subsoil to the spiral row On the earthenware, it is pushed to both sides of the ditch, equipped with a tractor with a power of 8.82-22.05kW, a speed of 50-300m/h, and a ditch depth of 0.5-1.2m. The walls of the ditch are neat, no soil is left at the bottom of the ditch, and the width and depth of the ditching operation are easy to adjust. However, a tractor equipped with an ultra-low speed or an ultra-low speed transmission device is required for normal operation.

At present, most domestic ditching machines are single-row ditching, with low operating efficiency, and there are few ditching machines suitable for matching with medium and large tractors. Many double-row hanging trenchers have the disadvantage of residual soil at the bottom of the ditch. The utility model combines the ditching machine and the fertilizing machine to complete the whole mechanization of ditching, fertilizing and soil covering at one time. Therefore, this new type of deep ditching and deep fertilizing machine is designed, which is used together with large and medium power wheeled tractors. Double row ditching, good maneuverability, standardized ditch type, uniform throwing of soil, leveling of soil return, adjustable ditching depth, etc., can also be used for other agricultural production ditching operations at the same time, it is an ideal ditching method for orchards Fertilization equipment.
