Embodiment 1

[0015] A knapsack type no-tillage precision fertilization device for orchards, comprising a knapsack fertilizer box 1, an adjustable strap 2, a fertilizer box switch 3, a fertilizer delivery hose 4, a fertilizer amount adjustment switch 5, a fertilizer feeding bucket 11, and negative pressure in the soil Conduit 6, opening and closing telescopic connecting rod 9, depth-adjustable fertilizer feeding cylinder 7, duckbill type fertilization port 8, soil entry pedal 10, fertilizer pushing plate 12, positioning conduit 13, handle 15, vent hole 14, opening and closing lever handle 16 and negative pressure vent 17. The knapsack fertilizer tank 1 is in an inverted trapezoidal shape, with adjustable straps 2 on both sides of the tank body, the fertilizer delivery hose 4 connected to the bottom of the tank body is connected to the fertilizer feeding bucket 11, and the fertilizer delivery hose 4 is equipped with a fertilizer tank switch 3 at the upper end , the lower end is equipped with...

Embodiment 2

[0021] The difference from the embodiment is that the negative pressure conduit 6 in the soil is connected to the opening and closing telescopic connecting rod 9, and the opening and closing telescopic connecting rod 9 is fixed on the connecting plate fixing frame 19 in the depth-adjustable fertilizer delivery tube 7 through the connecting rod rotating shaft 18. Depress the opening and closing pull rod handle 16, the opening and closing telescopic connecting rod 9 drives the connecting rod rotating shaft 18 and is fixed on the connecting plate fixing frame 19 in the depth-adjustable fertilizer delivery tube 7, the duckbill type fertilization port 8 is opened, and the backpack type fertilizer box 1 The granular fertilizer inside enters the fertilizer feeding bucket 11 through the fertilizer delivery hose 4, and is applied to the soil under the action of its own gravity and pushing force.

Embodiment 3

[0023] The difference from the embodiment is that the negative pressure conduit 6 in the soil is threadedly connected with the upper cover of the depth-adjustable fertilizer delivery tube 7 21, and the lower part is connected with the opening and closing telescopic connecting rod 9 in the tube, and the bottom of the depth-adjustable fertilizer delivery tube 7 is provided with a The positioning connection slot 20, the duckbill type fertilization port 8 is embedded between the inner spring 22 of the positioning connection slot 20 and the opening and closing telescopic connecting rod 9. Depress the opening and closing pull rod handle 16, and the opening and closing telescopic connecting rod 9 drives the depth adjustable spring 22 in the slot 20 at the bottom of the fertilizer delivery tube 7 . Under the action of the spring 22, the duckbill fertilization port 8 opens, and the granular fertilizer in the backpack fertilizer box 1 enters the fertilizer lower bucket 11 through the fer...

Abstract

The invention relates to back-mounted orchard no-tillage precise fertilization apparatus. The back-mounted orchard no-tillage precise fertilization apparatus is characterized in that adjustable straps are arranged on the two sides of a back-mounted fertilizer can, the fertilizer can is communicated with a cane-like fertilizer discharge barrel through a fertilizer conveying hose, a switch is installed on the fertilizer conveying hose, a soil feeding pedal is arranged on the outer side of the middle of a barrel body, the lower portion of the barrel body is provided with a depth-adjustable fertilizer conveying pipe and a duckbilled fertilization port, the top end of the barrel body is provided with a negative pressure air leakage port, and in the barrel body, a soil inner negative pressure guide pipe is connected with an opening and closing pull rod handle, and the soil inner negative pressure guide pipe passes through the negative pressure air leakage port and penetrates through a fertilizer pushing disk in the barrel body to be connected with an opening and closing telescopic connecting rod. The back-mounted orchard no-tillage precise fertilization apparatus is simple in structure and convenient to carry, use and operate; granulated fertilizer can be applied into soil under a no-tillage or no-excavation condition to directly act on the roots of fruit trees, precise positioning fertilization is realized, the use amount of the fertilizer is reduced, the utilization efficiency of the fertilizer is improved, and the apparatus is suitable for application and popularization in the field of orchard production and scientific research.

Description

technical field [0001] The invention relates to a no-tillage precision fertilization device for a backpack type orchard. Background technique [0002] In the process of fertilizing fruit trees in the orchard, the granular fertilizer is applied into the soil without plowing or digging, and directly acts on the roots of the fruit trees, which is conducive to the direct absorption of the fruit trees, realizes precise fertilization, reduces the amount of fertilizer used, and improves Improve fertilizer use efficiency and reduce pollution to soil and environment. The traditional method is to fertilize the orchard after plowing or digging, and then rake or cover the orchard. Reduced fertilizer use efficiency and effectiveness. Contents of the invention [0003] Based on the above, the purpose of the present invention is to provide a no-tillage precision fertilization device for backpack orchards. Using the structural characteristics of the device, it can realize precise positi...
