A hole-pressing water spraying device and method for seeding in hole trays

Abstract

The invention discloses a hole-pressing and spraying device and method for seeding in plug trays. The device includes a frame, a hole-disc conveying mechanism, a hole-pressing spraying mechanism and a water supply mechanism, a hole-discharging mechanism, a hole-pressing spraying mechanism and a water supply mechanism. The water supply mechanism is respectively installed on the frame, and the hole plate is set on the hole plate conveying mechanism; Cave holes correspond to one-to-one cavitation spraying heads, and the water supply mechanism is connected with the cavitation spraying mechanism. The method is that after the acupoint plate is sent to the bottom of the acupoint-pressing spray mechanism, the acupoint-pressing spray mechanism is started, and the matrix in each hole on the acupoint plate is pressed down by the acupoint-pressing spray head; Move, start the water supply mechanism, and spray water to the matrix in each hole on the hole plate through the hole-pressing spray head. The present invention can integrate the two links of pressure-cavity operation and water-spraying operation on the same station, which ensures the quality of pressure-cavity-pressure and spraying operations, and can effectively improve production efficiency.

Description

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

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
