Embodiment 1

[0064] like figure 1 As shown, a granular fertilizer spreading device is arranged on a fertilizer applicator, including a control circuit 1, a driving device 2, a fertilizer scraping device 3, a fertilizer box 4, a fertilizer pipeline 5, a human-computer interaction module 6, a fixed bracket 7 and Trunk detection module 8; wherein:

[0065] The control circuit 1, the driving device 2, the fertilizer scraping device 3, the fertilizer box 4, the fertilizer pipeline 5, the human-computer interaction module 6, and the trunk detection module 8 are all arranged on the fixed bracket 7, and the fixed bracket 7 is arranged to communicate with the on the fertilizer spreader;

[0066] The bottom of the fertilizer box 4 is provided with a discharge port, and the feeding end of the fertilizer lowering pipeline 5 is arranged below the discharge port;

[0067] The fertilizer scraping device 3 is arranged on the edge of the fertilizer box 4, and the granular fertilizer in the fertilizer box...

Embodiment 2

[0106] More specifically, on the basis of Embodiment 1, a control method for a granular fertilizer gap spreading device is provided, comprising the following steps:

[0107] S1: preset the detection distance of the trunk detection module 8 in the control circuit 1 through the human-computer interaction module 6, and the detection frequency is 0.2s / time;

[0108] S2: In the forest working environment, the trunk detection module 8 starts to detect the trunk, and reads the distance data in real time according to the detection frequency, that is, the distance data of the TOF sensor. The distance calculated by the bit spacing and the traveling speed of the fertilizer applicator is preset in the control circuit 1 through the human-computer interaction module 6. Delay time Xs;

[0109] S3: After the delay time Xs, control the driving device 2 to work by sending a control signal through the control circuit 1, the driving device 2 executes the corresponding driving speed according to t...

Abstract

The invention provides a granular fertilizer spreading device, which includes a control circuit, a driving device, a fertilizer scraping device, a fertilizer box, a fertilizer pipe, a human-computer interaction module, a fixed bracket and a tree trunk detection module; wherein, the control circuit is used to control the whole During the working process of the spreading device, the tree trunk is identified by the trunk detection module, and after a certain delay is set, the circuit drive device rotates, thereby driving the fertilizer scraping device to rotate; the fertilizer stored in the fertilizer box is scraped out of the fertilizer box by the fertilizer scraping device, from The feed outlet is sprinkled into the fertilizer pipe, and the fertilizer is spread through the discharge end of the fertilizer pipe; through the human-computer interaction module, the control parameters can be written into the control circuit in real time to realize the control of the spreader. Through the fixed-distance detection, the delay is set according to the distance between the trees, and then the fertilizer scraping device is driven to achieve the purpose of precise fertilizer application and intermittent application, which can promote the absorption of fertilizer by trees while saving resources; The structure is simple and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of fertilization equipment, and more specifically, to a granular fertilizer gap spreading device and a control method thereof. Background technique [0002] In the existing forest land fertilization process, the forest land ditch fertilization machine often adopts the method of opening ditch and continuous fertilization, and its work efficiency can be significantly improved compared with the traditional fertilization technology. The Chinese invention patent application with the publication number CN106612826A disclosed a ditching and fertilizing machine on May 10, 2017, including a chassis, a frame mounted on the chassis, a digging device installed on the frame, and a cutting and ditching device , a lifting device and a fertilizing mechanism, the chassis is provided with an engine and a chassis traveling device, the earth digging device includes a first chain and a digging shovel installed on the outer ring ...
