Description

A water-fertilizer integrated automatic fertilizer adding device

Technical Field

The utility model relates to the field of water-fertilizer integration, and in particular to an automatic fertilizer adding device for water-fertilizer integration.

Background Art

Integrated water and fertilizer technology refers to a new agricultural technology that integrates irrigation and fertilization. Integrated water and fertilizer technology uses a pressure system (or natural terrain drop) to mix soluble solid or liquid fertilizers according to the soil nutrient content and the fertilizer requirements and characteristics of the crop types. The fertilizer solution is mixed with irrigation water and supplied through a controllable pipeline system. After the water and fertilizer are mixed, drip irrigation is formed through pipelines and drippers to evenly, regularly and quantitatively infiltrate the root development and growth area of the crop, so that the main root soil always maintains looseness and appropriate water content; at the same time, according to the fertilizer requirements of different crops, soil environment and nutrient content, the water requirements of crops in different growth periods, and the fertilizer requirements, the needs of different growth periods are designed, and water and nutrients are provided to crops directly in a regular and quantitative manner in proportion. However, the existing integrated water and fertilizer fertilization equipment is difficult to quantitatively feed, and it is impossible to couple water and fertilizer according to the specific fertilizer amount required by different crops. The dosage needs to be manually controlled, which affects the degree of automation of integrated water and fertilizer, and there is a problem that soluble fertilizers cannot be effectively mixed. The phenomenon of mixing with water causes uneven fertilization. For this purpose, the application number is CN202222419845.7, which discloses an automatic fertilization device for integrating water and fertilizer. The first motor is arranged to drive the threaded rod to rotate, the threaded rod drives the sleeve to move up and down, the sleeve drives the lifting plate to move, the lifting plate drives the rotating shaft to move, and the second motor drives the rotating shaft to rotate, thereby driving the stirring blade to rotate and move up and down in the barrel body. This structure can make the water and soluble fertilizer inside the barrel body fully mixed and evenly mixed, so that the fertilization is more uniform; the third motor is arranged to drive the gear to rotate, and the gear and the gear teeth are engaged to drive the limiting disk to rotate. When the discharge port on the limiting disk rotates to coincide with the discharge pipe, the fertilizer in the storage tank falls into the feeding frame, and then falls into the barrel body for water and fertilizer mixing. Under the action of the limiting disk, this structure is convenient for quantitatively transporting the fertilizer into the barrel body through the discharge port, plays a role of quantitative addition, and improves the automation degree of water and fertilizer integration.

However, the above scheme still has certain defects. The inventors have found through research that in the above scheme, a limiting disk is arranged below the discharge pipe of the storage tank, and a plurality of discharge ports distributed in a ring are arranged on the limiting disk. The discharge ports are connected with the discharge pipe in turn through the rotation of the limiting disk to carry out quantitative distribution and delivery. However, this distribution method may cause the fertilizer in the discharge pipe to leak into the gap between the discharge pipe and the limiting disk when the discharge pipe and the discharge port are misaligned, resulting in a waste of fertilizer. Long-term use may lead to a large amount of fertilizer leaking in the gap, which will also affect the rotation efficiency of the limiting disk and affect the overall use effect and life of the device.

How to invent a water-fertilizer integrated automatic fertilizer adding device to improve these problems has become an urgent problem to be solved by technicians in this field.

Please refer to Figures 3 and 4. The material blocking mechanism includes a first material blocking plate 203 and a second material blocking plate 204 arranged in parallel with each other. A first slot 207 corresponding to the first material blocking plate 203 is provided on one side of the surface of the feed pipe 201. A second slot 208 corresponding to the second material blocking plate 204 is provided on one side of the surface of the feed pipe 201.

When the blocking mechanism is in the closed state, the fertilizer in the storage barrel 4 will first be blocked by the first blocking plate 203 after entering the feed pipe 201 from one end of the feed pipe 201. When the blocking mechanism is driven by the driving mechanism to slide independently upward relative to the feed pipe 201 and the discharge pipe 202, the first blocking plate 203 and the second blocking plate 204 will rise upward, and the bottom end of the first blocking plate 203 is located in the first slot 207, while the bottom end of the second blocking plate 204 is located in the connecting groove 209, so that the fertilizer in the feed pipe 201 will slide downward along the feed pipe 201 and continue to be blocked by the second blocking plate 204.

When the first motor 212 drives the threaded rod 211 to rotate in different directions, because the connecting plate 205 is threadedly connected to the threaded rod 211 through the protrusion 210 and the sliding connection between the first baffle plate 203 and the second baffle plate 204 and the first slot 207 and the second slot 208 are restricted, the connecting plate 205 will drive the first baffle plate 203 and the second baffle plate 204 to move up and down, so that the first baffle plate 203 and the second baffle plate 204 can be reciprocated and lifted to perform quantitative material distribution in a cycle.

Furthermore, a limiting plate 213 is fixedly mounted on the other end of the threaded rod 211 .

The limiting plate 213 can limit the maximum height to which 205 can be raised, thereby ensuring stability during use.

Furthermore, the inner wall of the blanking notch 206 is a symmetrical inclined surface with an inclined angle, and the connection position of the two inclined surfaces corresponds to the inner wall of one side of the connecting groove 209.

When the bottom ends of the first baffle plate 203 and the second baffle plate 204 are attached to the inner wall of one side of the feed pipe 201, the fertilizer between the first baffle plate 203 and the second baffle plate 204 will enter the discharge pipe 202 through the discharge notch 206. The inclined design can prevent the fertilizer from remaining in the discharge notch 206 and affecting the accuracy of quantitative distribution.

Each stirring rod 302 is provided with a plurality of groups of stirring blades 303 evenly distributed along the extension direction thereof. The stirring component 3 also includes a linkage mechanism for driving the rotating shaft 301 to rotate.

When the blocking mechanism is driven by the driving mechanism to slide upward independently relative to the feed pipe 201 and the discharge pipe 202, the first blocking plate 203 and the second blocking plate 204 rise upward, and the bottom end of the first blocking plate 203 is located in the first slot 207, and the bottom end of the second blocking plate 204 is located in the connecting groove 209, so that the fertilizer in the feed pipe 201 will slide downward along the feed pipe 201 and continue to be blocked by the second blocking plate 204. At this time, the driving mechanism drives the first blocking plate 203 and the second blocking plate 204 to descend and reset. At this time, the fertilizer between the first blocking plate 203 and the second blocking plate 204 will The fertilizer slides into the discharge pipe 202 through the discharge notch 206. When the driving mechanism drives the first baffle plate 203 and the second baffle plate 204 to rise for the next time to perform the above action, the fertilizer that entered the discharge pipe 202 last time loses the obstruction of the second baffle plate 204 and enters the mixing barrel 1 through the discharge pipe 202, thereby completing the quantitative feeding work. The quantitative feeding component 2 can avoid the use of a turntable, and a plurality of annularly distributed storage troughs are arranged on the turntable to connect with the discharge pipe in turn for quantitative feeding.
