Technical Field

The utility model relates to a soilless culture field specifically is a soilless culture device.

Background

With the improvement of living standard of people, people pay more attention to health, and the selection of crops is more inclined to eat green and pollution-free crops. However, what the soil is adopted for planting is inevitable is the pollution of the soil to crops, and the controllability is low. Therefore, a soilless culture mode is provided, and during planting, the nutrient solution is used for supplying nutrients required by crops without using soil. With the popularization of automation, some enterprises specially used for soilless vegetables adopt modern mechanical means to realize soilless cultivation of the vegetables, and the mode generally adopted is that automatic machinery is used for completing cultivation, seedling raising, growing, harvesting and packaging.

In the crop growth process, in order to save corresponding water resources or nutrient solution resources, the prior art provides a seedling culture bed frame integrating irrigation and seedling culture, which comprises a fixed platform, a seedling culture frame fixed on the fixed platform, and a hollow frame arranged along the side edge of the seedling culture frame, wherein the hollow frame is provided with a water pipeline and a spray irrigation support, and the spray irrigation support is provided with a spray head communicated with the water pipeline; the cultivation frame that grows seedlings sets up in the slope, and the low side of cultivation frame that grows seedlings is equipped with the return line for retrieve the unnecessary moisture that collects on the cultivation bedstead that grows seedlings, the water storage tank is connected to the other end of return line, and the bottom of water storage tank is provided with the blowoff valve. The water storage tank is communicated with a water delivery pipeline of the seedling culture bed frame through a filtering device, and the recovered water is recycled.

However, the above-described scheme has the following problems: firstly, the seedling culture shelf is obliquely arranged, so that crops placed on the seedling culture shelf tend to move towards the lower end of the seedling culture shelf, and the crops slide off from the seedling culture shelf; secondly, when the growth state of the crops reaches the harvesting state, workers are not easy to take down the crops positioned in the middle of the seedling cultivation frame, and the workers need to continuously go back and forth between the middle of the seedling cultivation frame and the crop harvesting point, so that a large amount of repeated labor of the workers is caused, and the manpower resource is wasted.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a soilless culture device can reduce the repeated labor that workman's reciprocating motion caused when reaping the crop, avoids the waste of manpower resources.

The utility model provides a basic scheme is: a soilless culture device comprises a culture bed, wherein a culture channel for supplying water to circulate is arranged on the culture bed, pulley mechanisms are arranged on two sides of the culture channel, a seedling tray is arranged on the culture channel, and two ends of the seedling tray are respectively in sliding connection with the pulley mechanisms on two sides of the culture channel; the tail end of the cultivation channel in the water flow direction is rotatably connected with a baffle plate for blocking the seedling tray; the cultivation bed is provided with a sensor for detecting the growth state of crops at the tail end along the water flow direction, the cultivation bed is provided with a controller and an alarm, and the sensor and the alarm are electrically connected with the controller.

The basic scheme has the working principle and the beneficial effects that: the controller is used for starting the alarm according to the signal detected by the sensor, the height of the sensor is related to the crop, the height of the sensor in the mature period of different crops is different, and the sensor is arranged according to the height of the crop in the mature period. The cultivation channel is supplied with water or nutrient solution to flow therein, thereby supplying nutrients required by crops. The pulley mechanism is arranged and is in sliding connection with two ends of the seedling raising plate, and therefore the seedling raising plate can slide on the pulley mechanism along the water flow direction. The setting of baffle can block to educate seedling tray and drop from cultivating the way, and makes to educate seedling tray and can say adjacent placing each other on cultivating the way to realize educating the crop on seedling tray and grow on cultivating the way. The sensor is arranged and used for detecting whether the growth state of the crops reaches the mature state or not, if the growth state of the crops reaches the mature state, the sensor detects signals, the controller starts the alarm according to the signals detected by the sensor, and therefore workers are reminded to reap the crops in the mature state according to the alarm.

When cultivating crops, cultivating the crops in batches in order to keep the crops harvested in each period, for example, dividing the growth of the crops on a cultivation bed into an early stage, a middle stage and a final stage, and placing a first crop on the cultivation bed, wherein the first crop is positioned at the head end of a cultivation channel along the water flow direction; when the first batch of crops reaches the middle stage, placing the second batch of crops on the cultivation bed, wherein the first batch of crops are positioned at the middle end of the cultivation channel, and the second batch of crops are positioned at the head end of the cultivation channel along the water flow direction; and when the second batch of crops reaches the middle period, placing the third batch of crops on the cultivation bed, and placing the first batch of crops, the second batch of crops and the third batch of crops on the cultivation bed in sequence from the tail end to the head end of the water flow direction.
