Hole pressing and water spraying device and method for hole tray seeding

Abstract

The invention discloses a hole pressing and water spraying device and method for hole tray seeding. The device comprises a rack, a hole tray conveying mechanism, a hole pressing and spraying mechanism and a water supply mechanism, the hole tray conveying mechanism, the hole pressing and spraying mechanism and the water supply mechanism are respectively mounted on the rack, and a hole tray is arranged on the hole tray conveying mechanism; the hole pressing and spraying mechanism and the water supply mechanism are arranged above the hole tray conveying mechanism in a crossing manner, hole pressing and spraying heads in one-to-one correspondence with holes in the hole tray are arranged in the hole pressing and spraying mechanism, and the water supply mechanism is connected with the hole pressing and spraying mechanism. The method comprises the following steps: after the hole tray is conveyed to the lower part of the hole pressing and spraying mechanism, the hole pressing and spraying mechanism is started, and a matrix in each hole in the hole tray is pressed down by the hole pressing and spraying heads; after hole pressing is completed, the hole tray is kept still, the water supply mechanism is started, and water is sprayed to the matrix in each hole in the hole tray through the hole pressing and spraying heads. According to the device and method, the two links of hole pressing operation and water spraying operation can be completed at the same station in an integrated mode, the quality of hole pressing and spraying operation is guaranteed, and the production efficiency can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of industrialized seedling cultivation, in particular to a hole-pressing and watering device and method for seeding in hole trays. Background technique [0002] Due to the advantages of high emergence rate, neat emergence, easy transplanting, and high production efficiency, industrial seedling cultivation has developed rapidly in my country's facility production. The tray seeding production line is the primary key equipment for industrialized seedling production. Usually, it is mainly composed of matrix filling machine, hole pressing machine, seeding machine, soil covering machine and watering machine. [0003] Among them, the hole press machine is mainly used to compact the filled substrate in the hole, so that the substrate in the hole can continuously absorb water and the root system of the seedling is firm and not loose, and at the same time meet the agronomic requirements for seed sowing depth and soil ...

AI Technical Summary

Problems solved by technology

For example, in the utility model application with the application number 201420835016.X, a detection device is added to the water spray device, and the accurate spray after the tray arrives is realized by controlling the power on and off of the solenoid valve; the water in this spray method not only pours into the The substrate in the hole will also be sprayed on the outer tray of the hole. Under the condition of high-speed sowing, in order to ensure the moisture content of the substrate, the water spray pipe usually needs to set a larger flow rate, and it will be sprayed on the outer tray of the hole. The water is easy to splash to both sides of the tray, which not only wastes water resources, but also easily causes pollution to the production environment

In the invention application with the application number 202010746766.X, a single-row sprinkler head shower method is adopted, and a regulating valve is added to each sprinkler head, and the spraying range can be adjusted by adjusting the valve, so that the spray water can Accurately fall into each hole of the tray, and control the water output of each outlet to be consistent, to achieve accurate and even watering, but when a row of holes to be sprayed moves to the right below the sprinkler head, the tray needs to stop There is a problem of low efficiency when the water spraying operation is started after exercise

[0007] In the existing tray seeding production line, in order to ensure the quality of the work, the acupressure machine and the water spraying machine need to stop the movement of the acupoints first, and then drive the acupressure heads or nozzles to align with the centers of the holes in the acupoints, and then perform acupressure or Sprinkling operation, there is a problem of pressure hole or low spraying efficiency

However, if the tray keeps moving continuously during the pressing or spraying operation, high production efficiency can be obtained, but it is difficult to guarantee the accuracy of the pressing or watering operation
