Description

Technical Field

[0001] The utility model relates to the technical field of feeding mechanisms of fertilizer equipment, in particular to a feeding mechanism of a fertilizer device for alfalfa planting. Background Art

[0002] Alfalfa is an annual or perennial herb; it has tripinnate compound leaves, small leaflets with small teeth, and veins extending into the tips of the teeth. Alfalfa is generally an important forage plant and can also be used as food. It can be blanched in hot water and served cold. It tastes excellent and has certain medicinal value.

[0003] For alfalfa planting, the traditional method is to dig a hole in the land manually first, and then fertilize after the digging operation is completed. During the fertilization process, the fertilizer will be concentrated into the collection box. However, in actual use, the fertilizer is exposed to moisture in the daily environment. The moisture-affected fertilizer often condenses into lumps, or even sticks to the inner wall of the collection box, which will cause the feeding port to be blocked and the fertilizer cannot be put down, affecting the fertilizer feeding effect. Therefore, a feeding mechanism of a fertilization device for alfalfa planting is needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Preferably, a conveying wheel is rotatably installed inside the discharge bin disc, and one end of the conveying wheel shaft passes through the discharge bin disc and is connected and fixed to the output end of the motor. The motor is fixed on the surface of the discharge bin disc, and the rotation speed of the conveying wheel can be controlled by controlling the output end after the motor is started, thereby quantitatively conveying the amount of material discharged.

[0008] Preferably, a fan-shaped opening is provided on the surface of the top cover, and a triangular structure is formed between the blade stem and the scraper. Through the fan-shaped opening design of the top cover, alfalfa fertilizer can be added into the feed hopper during the operation of the rotating shaft.

[0009] Preferably, the hanging assembly includes an upper connecting plate fixedly connected to the bottom end of the feed hopper, and the bottom end of the upper connecting plate is connected to a rubber material tube, and the bottom end of the rubber material tube is connected to a lower connecting plate, and two supporting springs are symmetrically connected between the upper connecting plate and the lower connecting plate at a position close to the rubber material tube, and a supporting spring is arranged between the supporting spring and the lower connecting plate, so that the rubber material tube has movable, telescopic and adjustable properties.

[0010] Preferably, a hanging plate is connected to the left side of the lower connecting plate, and the hanging plate is fixed to the hanging seat by bolts, and the bottom end of the hanging seat is connected to the fertilizer frame, and the entire device can be suspended and installed by bolting the hanging plate and the hanging seat.

[0011] Preferably, the bottom end of the lower connecting plate is connected and fixed to the top end of the discharge bin plate, and a vibrator is installed on the outside of the feed hopper.

[0012] Preferably, a trapezoidal bucket groove is provided on the surface of the conveying wheel, and the opening of the trapezoidal bucket groove is larger than the inner diameter of the opening at the top of the discharge bin plate. The large-diameter trapezoidal bucket groove design of the conveying wheel facilitates the reception of alfalfa fertilizer.

[0013] The utility model has at least the following beneficial effects:

[0014] 1. By setting up a scraping component, the anti-sticking treatment of the inner wall of the feed hopper is achieved. Compared with the traditional structure, this device drives the rotating shaft to rotate after the driving motor is started, so that the rotating shaft cooperates with the blade rod to drive the scraper to move, and the scraper is used to scrape the inner wall of the feed hopper, so that the damp material falls off. At the same time, the blade rod can break up the damp clumping material during rotation to avoid direct blockage of the lower end of the feed hopper, thereby ensuring the normal sprinkling of alfalfa fertilizer.

[0015] 2. By setting up a hanging component, the anti-blocking effect of alfalfa fertilizer inside the feed hopper is further improved. The device is connected to the bottom end of the feed hopper through an upper connecting plate, and the lower connecting plate and the upper connecting plate are connected through a rubber material pipe. When the vibrator is started, the feed hopper can vibrate along with the rubber material pipe, and then the alfalfa fertilizer can fall loosely, reducing the probability of the alfalfa fertilizer being compressed and accumulated.

[0025] A fan-shaped opening is formed on the surface of the top cover 41 , and a triangular structure is formed between the blade rod 44 and the scraper 45 .

[0026] The hanging assembly 2 includes an upper connecting plate 21 connected and fixed to the bottom end of the feed hopper 1, and the bottom end of the upper connecting plate 21 is connected to a rubber material tube 22, and the bottom end of the rubber material tube 22 is connected to a lower connecting plate 24, and two supporting springs 23 are symmetrically connected between the upper connecting plate 21 and the lower connecting plate 24 near the rubber material tube 22.

[0028] The bottom end of the lower connecting plate 24 is connected and fixed to the top end of the discharge bin plate 31 , and a vibrator 28 is installed on the outside of the feed hopper 1 .

[0029] A trapezoidal bucket groove is formed on the surface of the conveying wheel 32 , and the opening of the trapezoidal bucket groove is larger than the inner diameter of the opening at the top of the discharge bin plate 31 .

[0030] After the motor 33 is started, the speed of the output end is controlled to control the rotation of the conveying wheel 32, and then the amount of material discharged is quantitatively conveyed. Through the fan-shaped opening design of the top cover 41, alfalfa fertilizer can be added to the inside of the feed hopper 1 during the operation of the rotating shaft 43. The rotating shaft 43 can break up the alfalfa fertilizer to facilitate the feeding operation of the alfalfa fertilizer. The support spring 23 is arranged between the support spring 23 and the lower connecting plate 24, so that the rubber material tube 22 has movable telescopic adjustment, which is convenient for the rubber material tube 22 to shake and drop the accumulated materials during the activity, thereby reducing the blockage of the alfalfa fertilizer in the rubber material tube 2 2, by connecting the bolts between the hanging plate 25 and the hanging seat 26, the entire device can be suspended and installed.

The conveying wheel 32 conveys the alfalfa fertilizer to the position of the discharge pipe 34 and then falls to complete the fertilization operation.

[0032] Secondly, according to the attached Figure 1 With attached Figure 2 As shown, when the alfalfa fertilizer becomes damp and sticks to the inner wall of the feed hopper 1, the drive motor 42 can be started so that the output end of the drive motor 42 drives the rotating shaft 43 to rotate, and the rotating shaft 43 can cooperate with the blade rod 44 to drive the scraper 45 to scrape the inner wall of the feed hopper 1. During the scraping process, the blade rod 44 can break up the clumped alfalfa fertilizer so that the alfalfa fertilizer can fall to the bottom of the feed hopper 1.
