Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a device for quantitatively applying microbial liquid fertilizer to paddy fields. Background Art

[0002] The microbial liquid fertilizer rice field quantitative application device is a modern agricultural equipment designed specifically for rice field fertilization. It integrates modern precision agricultural technology and aims to efficiently, evenly and accurately apply liquid fertilizer containing microorganisms to optimize fertilizer utilization, promote the healthy growth of rice field crops, and reduce environmental pollution.

[0003] The existing quantitative application device of microbial liquid fertilizer for rice fields uses a water pump to extract liquid fertilizer from a water tank to achieve continuous fertilization of the rice fields. However, since the water pump is not convenient for intermittently controlling the spraying of liquid fertilizer, it is not convenient to meet the intermittent fertilization needs of the rice fields.

[0004] Therefore, a device for quantitatively applying microbial liquid fertilizer to rice fields has been developed, which is convenient for intermittently spraying liquid fertilizer into rice fields in a quantitative manner, so as to meet the intermittent fertilization needs of rice fields. Utility Model Content

[0005] In order to overcome the shortcomings of existing microbial liquid fertilizer quantitative application devices for rice fields, which are not convenient for intermittently controlling the spraying of liquid fertilizer and thus not convenient for meeting the intermittent fertilization needs of rice fields, the utility model provides a microbial liquid fertilizer quantitative application device for rice fields, which is convenient for intermittently spraying liquid fertilizer into rice fields in a quantitative manner to meet the intermittent fertilization needs of rice fields.

[0006] The technical solution is: a device for quantitatively applying microbial liquid fertilizer to rice fields, including a storage barrel, a motor, a screw, a first partition, a first spring, a second partition, a first guide column and an atomizer. The motor is connected to the upper middle side of the storage barrel, the screw is connected to the motor output shaft, the first partition is threadedly connected to the lower part of the screw, the first partition is in contact with the storage barrel, the first guide column is rotatably connected to the lower side of the screw, the second partition is slidably connected to the lower part of the first guide column, the second partition is in contact with the storage barrel, the first spring is connected between the first guide column and the second partition, and the atomizer is connected to the lower side of the storage barrel.

[0007] Furthermore, a plurality of fixing rings are provided on the upper side of the storage barrel.

[0008] Furthermore, a feed pipe is provided on the left side of the upper portion of the storage barrel.

[0009] Furthermore, the atomizer is provided with a plurality of atomizing nozzles.

[0010] Furthermore, it also includes a second guide column, the left part of the storage barrel is connected to the second guide column, and the second guide column is slidably connected to the first partition.

[0011] Furthermore, it also includes a third partition, a support rod and a second spring. The third partition is slidably connected to the lower right part of the storage barrel, the right side of the third partition is connected to the support rod, the support rod is slidably connected to the storage barrel, and the second spring is connected between the support rod and the storage barrel.

[0012] The beneficial effects of the utility model are as follows: 1. The utility model increases the internal pressure of the storage barrel by moving the first partition downward, so that the second partition moves downward along the first guide column, and the first spring is stretched to make the liquid fertilizer flow to the atomizer for atomization and spraying. When it is necessary to stop fertilizing, the first partition stops moving, so that the first spring rebounds, driving the second partition to reset and close the storage barrel, thereby achieving the effect of intermittently spraying the liquid fertilizer into the rice field in a quantitative manner, so as to meet the intermittent fertilization needs of the rice field.

[0013] 2. The utility model reduces the pressure at the atomizer and avoids affecting the normal operation of the atomizer by squeezing the third partition plate outwards by the liquid fertilizer when the pressure at the atomizer is too high, and the support rod moves outwards, and the second spring stretches. After the liquid fertilizer stops flowing out, the second spring rebounds and pushes the third partition plate to reset. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is described in detail below in conjunction with the accompanying drawings.

[0019] A device for quantitatively applying microbial liquid fertilizer to paddy fields, such as Figure 1-Figure 3As shown, it includes a storage barrel 1, a motor 2, a screw rod 3, a first baffle 4, a first spring 5, a second baffle 6, a first guide column 7, a second guide column 8, a third baffle 9, a support rod 10, a second spring 11 and an atomizer 12. The motor 2 is connected to the upper middle side of the storage barrel 1. Four fixing rings are arranged on the upper side of the storage barrel 1 to facilitate the carrying of the drone. A feeding pipe is arranged on the upper left side of the storage barrel 1 to facilitate feeding. The screw rod 3 is connected to the output shaft of the motor 2. The lower part of the screw rod 3 is threadedly connected to the first baffle 4. The first baffle 4 is in contact with the storage barrel 1. The left part of the storage barrel 1 is connected to the second guide column 8. 8 is slidably connected to the first partition 4, the first guide column 7 is rotatably connected to the lower side of the screw rod 3, the second partition 6 is slidably connected to the lower part of the first guide column 7, the second partition 6 is in contact with the storage barrel 1, and a first spring 5 is connected between the first guide column 7 and the second partition 6. An atomizer 12 is connected to the lower side of the storage barrel 1, and five atomizing nozzles are provided on the atomizer 12 to facilitate multi-directional spraying of fertilizers. The third partition 9 is slidably connected to the lower right part of the storage barrel 1, and a support rod 10 is connected to the right side of the third partition 9. The support rod 10 is slidably connected to the storage barrel 1, and a second spring 11 is connected between the support rod 10 and the storage barrel 1.

[0020] When using the utility model, firstly, the storage barrel 1 is fixed on the agricultural drone by a fixing ring, and then the motor 2 is started to drive the screw rod 3 to rotate, so that the first partition plate 4 moves along the second guide column 8 to the top of the feeding pipe, and then the microbial liquid fertilizer is introduced into the storage barrel 1 through the feeding pipe, and then the drone is controlled to move to the rice field that needs to be fertilized, and then the motor 2 is started to make the screw rod 3 rotate in the opposite direction, so that the first partition plate 4 moves downward, and the liquid fertilizer is squeezed downward. The internal pressure of the storage barrel 1 increases, so that the second partition plate 6 moves downward along the first guide column 7, and the first spring 5 is stretched to open the storage barrel 1, and the liquid fertilizer flows to the atomizer 12, is atomized by the atomizing nozzle, and then sprayed to In the rice field, when it is necessary to stop fertilizing, the motor 2 is turned off to stop the first partition 4 from moving, so that the first spring 5 rebounds, driving the second partition 6 to reset and close the storage barrel 1 to block the liquid fertilizer, thereby facilitating the intermittent quantitative spraying of liquid fertilizer into the rice field to meet the intermittent fertilization needs of the rice field. When the liquid fertilizer at the atomizer 12 is too much and the pressure is too high, the liquid fertilizer squeezes the third partition 9 to move outward, the support rod 10 moves outward, the second spring 11 stretches, and after the liquid fertilizer stops flowing out, the second spring 11 rebounds to push the third partition 9 to reset, thereby reducing the pressure at the atomizer 12 and avoiding affecting the normal operation of the atomizer 12.

[0021] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
