Description

Technical Field

[0001] This utility model relates to the technical field of fertilizer mixing devices, and in particular to a fertilizer mixing device for agricultural greenhouses. Background Technology

[0002] Currently, in agricultural greenhouses, crops need to be fertilized regularly to ensure their healthy growth. Before fertilizing, various fertilizers must be mixed with water. To ensure the uniformity of the fertilizer mixture, a stirring device can be used to increase the uniform dissolution and mixing of the fertilizer in the water.

[0003] Chinese Patent Publication No. CN221601767U discloses an agricultural fertilizer mixing device, including a mixing tank. A mixing motor is fixedly installed on the top of the mixing tank, and a main shaft is fixedly connected to the output end of the mixing motor. A connecting rod is fixedly connected to the main shaft, and a rotating shaft is rotatably connected to the connecting rod. A driven gear is fixedly connected to the rotating shaft.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Please see Figures 1-4 One embodiment of this utility model is an agricultural greenhouse fertilizer mixing device, comprising a mixing tank 1;

[0024] A motor 9 is installed at the bottom of the mixing tank 1, and a stirring shaft 10 is installed at the top of the motor 9. The top of the stirring shaft 10 passes through the mixing chamber 15 and extends into the interior of the pulverizing chamber 14. A pulverizing component 13 is provided on the outer surface of the stirring shaft 10 located inside the pulverizing chamber 14. A fixing sleeve 11 is fitted on the outer surface of the stirring shaft 10 located inside the mixing chamber 15, and stirring blades 12 are evenly installed on the outer side of the fixing sleeve 11.

[0025] The pulverizing assembly 13 includes a fixed platform 1301 sleeved on the outside of the stirring shaft 10, and pulverizing blades 1302 are evenly installed on the outside of the fixed platform 1301, and pulverizing blades 1303 are installed at the bottom of each of the pulverizing blades 1302. The bottom surface of the pulverizing chamber 14 is in the shape of an inverted funnel.

[0026] Specifically, such as Figure 1 , Figure 2 As shown, the crushing component 13 is used to pre-crush and cut the fertilizer, thereby improving the uniformity of subsequent fertilizer mixing.

[0027] The mixing tank 1 has a crushing chamber 14 at the top inside, and a feed inlet 16 on one side of the crushing chamber 14. The mixing tank 1 has a mixing chamber 15 at the bottom inside, and the mixing chamber 15 and the crushing chamber 14 are connected to each other. A baffle 3 is rotatably connected to the outside of the feed inlet 16, and guide sleeves 5 are fixed at the top of both sides of the baffle 3. Guide rods 4 pass through the inside of the guide sleeves 5, and both ends of the guide rods 4 are connected to the outside of the mixing tank 1. A U-shaped sealing gasket 17 is installed on the outer edge of the inner side of the baffle 3, and the outer surface of the U-shaped sealing gasket 17 abuts against the outer wall of the mixing tank 1. A lifting component 6 is provided on the outside of the baffle 3 to fix and drag the snake skin bag.

[0028] The lifting assembly 6 includes an electric telescopic rod 601 installed on the outside of the baffle 3, and a lifting plate 602 is installed at the bottom end of the electric telescopic rod 601. The inner side of the lifting plate 602 is slidably connected to the outer wall of the baffle 3. Lifting rods 603 are installed on both sides of the top of the lifting plate 602. The top of the lifting rods 603 penetrates the outer edge of the top of the baffle 3. The top of the lifting rods 603 is equipped with hooks 604. The hooks 604 are used to hook and fix one end of the snakeskin bag.

[0029] A bag-pressing assembly 18 is provided on the inner side of the baffle 3 near the hook 604. The bag-pressing assembly 18 includes a groove 1801 opened on the inner side of the baffle 3. Multiple springs 1802 are installed at equal intervals inside the groove 1801. The outer ends of the multiple springs 1802 are connected to a pressure plate 1803. The outer end of the pressure plate 1803 extends to the outside of the groove 1801.

[0030] Specifically, such as Figure 3 and Figure 4 As shown, during use, the lifting component 6 is used to pull the snakeskin bag upwards out of the crushing chamber 14. The fertilizer's own weight, along with the bag pressing component 18 and the gap limiting effect between the baffle 3 and the mixing tank 1, allows the fertilizer to be automatically discharged smoothly from the snakeskin bag. This also reduces the phenomenon of the snakeskin bag being generated inside the guide rod 4. Furthermore, the cooperation between the baffle 3 and the crushing chamber 14 greatly reduces the flying of fertilizer powder.

[0031] The top of the mixing tank 1 is equipped with an opening and closing mechanism 2;

[0032] The opening and closing mechanism 2 includes a movable plate 201 that is slidably installed on the top of the mixing tank 1. Both ends of the movable plate 201 away from the mixing tank 1 are equipped with electric push rods 202. One end of each electric push rod 202 is connected to the top of the mixing tank 1 through a connecting block 203. Two wire blocks 205 are distributed in parallel on the side of the top of the mixing tank 1 near the baffle 3. Each wire block 205 has a pull rope 204 passing through its interior. One end of each pull rope 204 is connected to one side of the movable plate 201, and the other end of each pull rope 204 is connected to the outside of the corresponding guide sleeve 5.

[0033] When the moving plate 201 moves closer to the baffle 3, the baffle 3 is flipped outward by the external gravity, so that the guide sleeve 5 slides in an arc along the outside of the guide rod 4 to open the feed port 16.

[0034] Furthermore, the two sides of the opening and closing mechanism 2 are respectively connected to the outer side of the corresponding guide sleeve 5, the bottom end of one side of the mixing chamber 15 is connected to the discharge pipe 7, and the top end of the other side of the mixing chamber 15 is connected to the water inlet pipe 8.

[0035] Specifically, such as Figure 1 As shown, during use, the extension and retraction of the electric push rod 202 is used to pull one end of the pull rope 204, thereby realizing the flipping effect of the baffle 3. Together with the U-shaped sealing gasket 17, the bag pressing assembly 18, etc., the closing effect of the feed inlet 16 is achieved.

[0036] Working principle: When using this utility model, first place the woven bag containing fertilizer on the end face of the horizontal baffle 3, and fix the closed end of the woven bag by hooking it with two hooks 604. Start the electric push rod 202 to shorten, so that the moving plate 201 pulls one end of the guide block 205 to move, so that the other end of the guide block 205 generates an upward pulling force on the guide sleeve 5, so that the guide sleeve 5 flips upward along the guide rod 4, so that the baffle 3 drives the woven bag to flip synchronously, so that the baffle 3 drives the U-shaped sealing gasket 17 to seal the feed port 16, and at the same time, the fertilizer in the woven bag is automatically discharged from the open end under its own weight.

[0037] Secondly, the electric telescopic rod 601 is shortened, causing the lifting plate 602 to drive the lifting rod 603 to rise, which in turn causes the hook 604 to move one end of the snakeskin bag upward to pull out the snakeskin bag and achieve automatic unloading. During the pulling out of the snakeskin bag, due to the elasticity of the spring 1802, the groove 1801 keeps squeezing the snakeskin bag closer to the outer wall of the mixing tank 1, so that the groove 1801 scrapes against the outer wall of the snakeskin bag, which helps to improve the pouring effect of fertilizer in the snakeskin bag.

[0038] Finally, the motor 9 is started, causing the stirring shaft 10 to rotate. This causes the fixed platform 1301 to drive the crushing blade 1302 to rotate, which in turn drives the crushing blade 1303 to rotate synchronously. Utilizing their sharpness, the fertilizer is crushed and cut as it is transferred from the crushing chamber 14 to the stirring chamber 15, thereby improving the uniformity of subsequent mixing. The water inlet pipe 8 is used to add water, which is then mixed with the fertilizer inside the stirring chamber 15. The stirring blade 12 is used to achieve the mixing effect between the fertilizer and water, and the discharge pipe 7 is used to discharge the fertilizer.
