Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural fertilizing device technical field, concretely is a kind of vegetable fertilizing device for agricultural greenhouse planting. BACKGROUND

[0002] Crop refers to the cultivation of various plants in agriculture, including food crops and economic crops (oil crops, vegetable crops, flowers, grasses, trees). Edible crops are one of the sources of basic food for humans. Food is the basis of life, expressing the relationship between man and food. Reasonable diet can bring health to humans, and self-sufficiency in food is the basis of sustainable development of a country. The growth of crops cannot be separated from scientific and technological production technology and new industrial machinery that can assist agricultural production.

[0003] At present, in the process of greenhouse vegetable fertilization, water-soluble fertilizer is often used for fertilization. However, water-soluble fertilizer is prone to deposit at the bottom of the container during fertilization, resulting in uneven distribution of water-soluble fertilizer. In addition, the existing fertilizing device uses electricity as power, which is very inconvenient to use in the greenhouse, and needs to drag the power line, which has certain safety hazards. UTILITARIAN CONTENT

[0004] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide a vegetable fertilizing device for agricultural greenhouse planting. The handle is pushed or pulled to move the vehicle body, and the rollers at the bottom of the vehicle body rotate. Since the rollers are connected to the gas compression device through the rotating plate, the rotating plate can drive the gas compression device to compress the gas when the rollers rotate. Since the gas compression device is connected to the compression chamber through the gas pipe, the compressed gas can enter the compression chamber, and the gas pressure in the compression chamber increases. The compressed gas can pass through the one-way valve and enter the chamber filled with water-soluble fertilizer in the storage tank.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] A vegetable fertilizing device for agricultural greenhouse planting, comprising a vehicle body, a roller is arranged at the bottom of the vehicle body, a handle is arranged at one end of the vehicle body, a storage tank is arranged at the end of the vehicle body top away from the handle, a gas compression device is arranged at the end of the vehicle body top close to the handle, a partition is arranged at the bottom of the storage tank, a compression chamber is isolated by the partition in the storage tank, the gas compression device and the compression chamber are connected by a gas pipe, a plurality of air inlet holes are arranged on the partition, a one-way valve is arranged in the air inlet hole, a spray pipe is arranged at the end of the vehicle body away from the handle and connected to the lower part of the storage tank, and the roller is connected to the gas compression device through a rotating plate.

[0007] Preferably, the gas compression device comprises a tank body, an opening is formed at the top of the tank body, a piston plate is installed at the opening, an installation column is arranged at the top of the piston plate, a connecting rod is arranged at the top of the installation column, a fixing column is arranged on the roller, and the two ends of the rotating plate are rotationally connected with the fixing column and the connecting rod respectively.

[0008] Preferably, an air inlet is arranged at the end of the compression cavity away from the air pipe, a sealing plate is arranged at the inner side of the compression cavity, and the top of the sealing plate is installed above the air inlet through a hinge.

[0009] Preferably, the one-way valve comprises an installation plate arranged at the upper end of the air inlet, a ball seat is arranged at the lower end of the air inlet, a blocking ball matched with the ball seat is arranged at the bottom side of the installation plate through a spring, the ball seat has a through hole in a conical shape, and the diameter of the through hole gradually decreases from top to bottom.

[0010] Preferably, the storage tank is internally provided with a stirring device, the stirring device comprises a stirring shaft arranged through the top of the storage tank, stirring blades are arranged on the stirring shaft, and a rotating handle is arranged at the top end of the stirring shaft.

[0011] Preferably, the top of the storage tank is provided with a tank cover, and a sealing ring is arranged at the tank cover.

[0012] Preferably, the partition plate is arranged in an inclined manner, and the end of the partition plate at a lower level is connected with the spraying pipe through a guide pipe.

[0013] Compared with the prior art, the utility model has the advantages that:

[0014] 1、The utility model discloses a simple structure, when the handle is pushed or pulled and the vehicle body moves to carry out fertilization, the roller at the bottom of the vehicle body can rotate, since the roller is connected with the gas compression device through the rotating plate, when the roller rotates, the rotating plate can drive the gas compression device to compress the gas, since the gas compression device is connected with the compression cavity through the air pipe, the compressed gas can enter the compression cavity, the air pressure in the compression cavity increases, the compressed gas can pass the partition plate through the one-way valve and enter the chamber filled with water-soluble fertilizer in the storage tank, since the gas enters from the partition plate and floats to the upper surface of the water-soluble fertilizer, air bubbles are formed, which can not only increase the pressure in the chamber, but also increase the uniformity and turbulence degree of the solution through the stirring effect of the air bubbles, can prevent the water-soluble fertilizer particles from depositing at the bottom, and the water-soluble fertilizer can be uniformly sprayed through the spraying pipe, and the device does not need power and does not need wire transmission, so that the safety hidden danger is reduced.

[0015] 2. In this device, the two ends of the rotating plate are rotatably connected to the fixed column and the connecting rod, respectively. When the roller rotates, it can drive the mounting column to move through the rotating plate. The piston plate at the bottom of the mounting column is installed inside the tank, thus driving the piston plate to move up and down inside the tank. Since one end of the compression chamber is equipped with an air inlet, and the compression chamber is connected to the tank through an air pipe, a sealing plate is installed at the air inlet through a hinge. Therefore, when the piston plate moves upward inside the tank, external gas can push the sealing plate through the air inlet and enter the compression chamber and the tank. When the piston plate moves downward inside the tank, the gas inside the tank enters the compression chamber through the air pipe. The sealing plate at the air inlet can completely seal the air inlet under its own weight. Because the gas inside the compression chamber has a higher pressure, it is easy for the gas to enter the storage tank containing water-soluble fertilizer through the one-way valve on the partition, which facilitates the stirring of the water-soluble fertilizer.

[0016] 3. The mounting plate of this device has a perforated structure. The spring at the bottom of the mounting plate can press the sealing ball into the conical through hole on the ball seat. When the gas pressure inside the compression chamber is high, the compressed gas can push the sealing ball open, and the spring is compressed, so that the gas can pass through the one-way valve into the storage tank containing water-soluble fertilizer. When the gas pressure inside the compression chamber decreases, the sealing ball is pushed back into the ball seat under the action of the spring to achieve the sealing effect.

[0017] 4. The inclined baffle of this device can ensure that the water-soluble fertilizer can flow completely to the guide pipe, which makes it easy to spray out all the water-soluble fertilizer in the storage box and avoid some water-soluble fertilizer remaining in the storage box, thus ensuring the utilization rate of water-soluble fertilizer.

[0018] 5. This device can drive the stirring shaft to rotate by rotating the handle, which facilitates the initial and thorough mixing of water-soluble fertilizer and water, ensuring the uniformity of fertilizer application. The sealing ring at the lid ensures the airtightness of the storage tank, which increases the gas pressure inside the storage tank. The entry of gas increases the pressure inside the storage tank, which helps to evenly spray the water-soluble fertilizer through the spray pipe. Attached Figure Description
