Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of konjac planting devices, specifically relating to a fertilization machine for konjac planting under forest cover. Background Technology
[0002] Understory konjac cultivation refers to the planting of konjac within or on the edge of forest land, utilizing the shade provided by the forest to offer a suitable growing environment. Understory konjac cultivation often employs a ridge-furrow planting method, requiring the application of both basal and foliar fertilizers. Currently, basal and foliar fertilizers are applied using different equipment. Furthermore, because konjac is planted on both sides of the ridges, with upright stems and leaves concentrated at the top of the plant, traditional spraying equipment has low fertilization efficiency. Therefore, this application proposes a fertilization machine for understory konjac cultivation. Utility Model Content
[0003] To overcome the problems in the background technology, this utility model provides a fertilizer application machine for konjac planting under forest cover, which solves the problem that different equipment is needed to spray base fertilizer and foliar fertilizer for konjac planting under forest cover, and that the fertilizer application efficiency of traditional spraying equipment is low due to the characteristics of ridge and furrow planting of konjac under forest cover.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:
[0005] A fertilizer applicator for konjac cultivation under forest cover includes a frame, a medicine tank, a pump, an atomizer, a ground application pipeline, and a spraying cylinder. The medicine tank, pump, and atomizer are mounted on the frame. The outlet of the medicine tank is connected to the inlet of the pump via a pipe. The ground application pipeline includes a control valve and a set of fertilizer application pipes extending from both sides of the frame. The control valve is connected to the first outlet of the pump, and the inlet of the fertilizer application pipes is connected to the control valve. The inlet of the atomizer is connected to the second outlet of the pump, and the outlet of the atomizer is connected to the spraying cylinder via a pipe. The spraying cylinder is mounted on top of the frame via a support frame.
[0006] Furthermore, the fertilizer application pipe is a flexible pipe, and the end of the fertilizer application pipe can be detachably installed with a dripper or a spray nozzle.
[0007] Furthermore, the spraying cylinder includes a fan installed at the front end, a motor installed inside the spraying cylinder, and a delivery pipe for the atomizer connected to a drug inlet facing the fan installed on the side wall of the spraying cylinder.
[0008] Furthermore, a dustproof plate is installed at the bottom of the frame, and a moisture-proof plate is installed at the top of the frame.
[0009] The beneficial effects of this utility model are:
[0010] This application incorporates a ground application pipeline and a spraying nozzle on the vehicle frame, enabling the application of both base fertilizer and foliar fertilizer to konjac. This solves the problem of requiring different equipment for spraying base fertilizer and foliar fertilizer in konjac cultivation under forest cover. Furthermore, considering the characteristics of konjac furrow planting, the ground application pipeline includes a set of fertilizer pipes extending from both sides of the vehicle frame. The spraying nozzle is mounted on top of the vehicle frame via a support frame, allowing simultaneous fertilization of plants on both sides of the furrow, thus solving the problem of low fertilization efficiency of traditional spraying equipment.

[0017] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.
[0018] This utility model discloses a fertilizer applicator for planting konjac under forest cover. (See reference...) Figure 1-4A fertilizer applicator for konjac cultivation under forest cover includes a frame 1, a medicine tank 2, a pump 3, an atomizer 4, a ground application pipeline 5, and a spray nozzle 6. The medicine tank 2, pump 3, and atomizer 4 are mounted on the frame 1. The outlet of the medicine tank 2 is connected to the inlet of the pump 3 via a pipeline. Water-soluble fertilizer is added to the medicine tank 2 and then pumped by the pump 3. The ground application pipeline 5 includes a control valve 51 and a set of fertilizer application pipes 52 extending from both sides of the frame 1. The control valve 51 is connected to the first outlet of the pump 3 and can control the application process. The fertilizer flow rate is controlled by connecting the inlet end of the fertilizer pipe 52 to the control valve 51. The fertilizer and water from the control valve 51 are applied to the soil on both sides through the fertilizer pipe 52. The inlet end of the atomizer 4 is connected to the second outlet end of the pump 3. The pumped fertilizer and water are atomized by the atomizer 4. The outlet end of the atomizer 4 is connected to the spray cylinder 6 through a pipe. The spray cylinder 6 is installed above the frame 1 through a support frame. The atomized fertilizer and water are blown by the atomizer 4 onto the konjac leaves covering the furrows.
[0019] See Figure 1-4 The fertilizer pipe 52 is a flexible pipe, and the end of the fertilizer pipe 52 can be detachably installed with drippers or nozzles, which can spray or drip fertilizer according to the fertilization needs.
[0020] See Figure 1-4 The spraying cylinder 6 includes a fan 61 installed at the front end, a motor installed inside the spraying cylinder 6, and a drug inlet 62 installed on the side wall of the spraying cylinder 6 facing the fan 61, which connects to the delivery pipe of the atomizer 4. The water and fertilizer delivered by the atomizer 4 enter the spraying cylinder 6 and are blown by the fan 61 and applied to the konjac leaf surface.
[0021] See Figure 1-4 The bottom of the frame 1 is equipped with a dustproof plate 11 to prevent dust pollution, and the top of the frame 1 is equipped with a moisture-proof plate 12 to prevent the equipment from being fogged up and wetted.
[0022] Work process:
[0023] Add water and fertilizer to the medicine tank 2 according to the fertilization needs. Move the vehicle frame 1 to the konjac furrow by operating the handle on the handle and the bottom wheels under the vehicle frame 1. Start the pump 3 as needed to pump the water and fertilizer in the medicine tank 2. You can choose to pump it separately to the ground application pipeline 5 or the atomizer 4 to apply base fertilizer or foliar fertilizer, or pump it at the same time to apply base fertilizer and foliar fertilizer together. When applying, the vehicle frame 1 moves along the furrow, and the fertilizer is applied to the soil on both sides of the furrow through the fertilizer application pipe 52 and applied to the konjac leaves through the spraying pipe 6.
