Fertilizer applicator

Abstract

The invention provides a fertilizer applicator comprising a frame, the front end of the frame is provided with a traction frame, the back end of the frame is provided with a walking wheel, a fertilizing device, a hole digging device and a soil covering device are arranged on the frame, the hole digging device comprises a hole digging device outer frame, a hole digging rotating shaft and a helical tooth are arranged in the hole digging device outer frame, the outer side wall of the hole digging device outer frame is connected with a hole digging lifting oil cylinder, the lower end of the hole digging lifting oil cylinder is fixed on the frame, and the lower end of the side wall of the hole digging device outer frame is hung above the frame; the fertilizing device includes a chemical fertilizer storage tank and a farm manure storage tank which are separated by a separator; a fertilizing control board is arranged between the side wall of the chemical fertilizer storage tank and the separator, the fertilizing control board is a scalable plate, one end of the scalable plate is fixed at the external of a fertilizer storage tank, and is connected with a fertilizing control oil cylinder, the lower part of the fertilizer storage tank is connected with a stirring tank, and the lower end of the stirring tank is connected with a fertilizer conveying pipe. The fertilizer applicator integrates the functions of hole digging, fertilizing and soil covering soil, and realizes the interval fertilization of a farmyard manure and a chemical fertilizer.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a fertilizer applicator. Background technique [0002] At present, agricultural fertilization generally adopts manual trenching and fertilization, which needs to carry heavy equipment for storing chemical fertilizers or farmyard manure, and then fertilizes a little bit on the side of the plants. After fertilization, it needs to be manually covered with soil. Underneath, fertilization is uneven, and the effect of fertilization is directly affected by the depth of fertilization; the current method of mechanical furrowing and fertilization will cause certain damage to the root system of the plant, not only making the fertilizer applied in the furrow unable to be fully absorbed by the roots of the fruit trees, resulting in waste of fertilizer, Moreover, the balance relationship between root system absorption of water and transpiration will also be destroyed, which is u...

[0002] At present, agricultural fertilization generally adopts manual trenching and fertilization, which needs to carry heavy equipment for storing chemical fertilizers or farmyard manure, and then fertilizes a little bit on the side of the plants. After fertilization, it needs to be manually covered with soil. Underneath, fertilization is uneven, and the fertilization effect is directly affected by the depth of fertilization; the current method of mechanical furrowing and fertilization will cause certain damage to the root system of the plant, not only making the fertilizer applied in the furrow unable to be fully absorbed by the roots of the fruit trees, resulting in waste of fertilizer, Moreover, the balance between water absorption and transpiration by the root system will also be destroyed, which is not conducive to the growth of plants, and it does not have the function of covering soil, so it still needs to be covered separately.

At the same time, the existing fertilization machine is to mix the fertilizers together, and the two fertilization tanks are arranged left and right, which cannot be used for the conventional fertilization method of farmyard manure and chemical fertilizer fertilization at intervals
