Description

Technical Field

[0001] The invention relates to a fertilizer loading and spreading machine for facility agriculture, in particular to a fertilizer loading and spreading device. Background Art

[0002] As a major agricultural nation, fertilization is a crucial measure for increasing soil nutrients and improving crop growth and development. However, excessive use of chemical fertilizers poses significant challenges. To reduce chemical fertilizer usage, the Ministry of Agriculture has introduced a series of policies aimed at replacing chemical fertilizers with organic fertilizers. However, organic fertilizer loading and spreading is primarily a manual process, characterized by low mechanization, high labor intensity, low efficiency, and low fertilization efficiency. This severely hinders agricultural development, particularly in the loading and spreading process within the vegetable industry chain. Prior art examples include the utility model patent disclosed in Publication No. CN211745310U, in which the output shaft ends of two motors are fixedly connected to the inner ends of the central shafts of track wheels mounted on the front and rear walls of the base. The shafts of the three track wheels on the same side are connected via a belt drive. Solenoid valves and a lower solenoid valve are configured to adjust the amount of fertilizer delivered, ensuring uniform fertilization of crops and preventing over-fertilization that can lead to nutritional overload. However, this design is relatively complex, lacks automated feeding, and lacks consistent fertilization, impacting the stability of fertilizer efficiency.

[0003] To this end, a fertilizer loading and spreading equipment suitable for greenhouse operations was designed and developed to provide efficient operating machinery for facility vegetable production and meet the needs of facility agriculture in major regions of my country. It has very important practical significance for improving the level of mechanized vegetable production in my country and implementing the relevant spirit of my country's vegetable work.

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figures 1-6As shown, the fertilizer spreading equipment includes a fertilizer box 10, a material diverter mechanism 20, a height adjustment mechanism 30, a horizontal adjustment mechanism 40 and a sealing plate assembly 50, wherein the material diverter mechanism 20 adjusts its height by the height adjustment mechanism 30, and adjusts its horizontal position in the fertilizer box 10 by the horizontal adjustment mechanism 40; the material diverter mechanism 20 includes a rotating shaft 21 that can rotate forward and backward and a paddle 22 arranged on the rotating shaft 21, usually, there are multiple paddles 22 evenly distributed along the axial direction of the rotating shaft 21, mostly 4-6 paddles, and multiple groups of 4-6 paddles 22 are evenly distributed along the horizontal direction of the rotating shaft 21, so that the paddle 22 can ensure the fertilizer spreading on the same horizontal plane by a single stroke in the fertilizer box 10. In this embodiment, the horizontal adjustment mechanism 40 includes a slide 41 symmetrically arranged on the outside of the fertilizer box 10 and a horizontal adjustment component 42 that can move horizontally along the slide 41, and the horizontal adjustment component 42 is connected to the material-dispensing mechanism 20 through the height adjustment mechanism 30; wherein the horizontal adjustment component 42 includes a slide 43, a slide hydraulic motor 44, a slide transmission component 45 and a slide driving wheel 46, the slide hydraulic motor 44 is installed on the slide 43, the slide hydraulic motor 44 is rotatably connected to the slide driving wheel 46 through the slide transmission component 45, and the slide driving wheel 46 performs horizontal linear reciprocating motion in the slide 41 under the drive of the slide hydraulic motor 44, thereby causing the slide 43 to drive the material-dispensing mechanism 20 through the height adjustment mechanism 30 The mechanism 20 performs horizontal linear reciprocating motion to adjust the horizontal position of the material-selecting mechanism 20 in the fertilizer box 10, and cooperates with the rotating paddle 22 to meet the quantitative loading or spreading of fertilizer in the fertilizer box 10; an opening 11 is left on one side of the fertilizer box 10, and the sealing plate assembly 50 includes a rotatable sealing plate 51, which rotates to open and close the opening 11 to meet the different amounts of fertilizer in the fertilizer box 10 when loading and spreading fertilizer; the slide transmission component 45 includes a slide transmission driving sprocket 47, a slide transmission chain 48, and a slide transmission driven sprocket 49. The slide transmission driving sprocket 47 is rotatably connected to the slide transmission driven sprocket 49 through the slide transmission chain 48, and the slide transmission driven sprocket 49 is rotatably connected to the chute driving wheel 46. Furthermore, a chute auxiliary wheel 460 can be installed on one side of the chute driving wheel 46. The chute auxiliary wheel 460 is also set in the chute 41, and the chute driving wheel 46 and the chute auxiliary wheel 460 are connected. In this way, the chute auxiliary wheel 460 rotates together with the chute driving wheel 46 and performs horizontal linear reciprocating motion in the chute 41. The chute auxiliary wheel 460 itself does not need to apply power, but can play a good balancing role to avoid imbalance during the horizontal movement of the horizontal adjustment component 42.

[0024] In a preferred embodiment, the material dispensing mechanism 20 further includes a roller cover 23, which is positioned above the paddle 22. By connecting the roller cover 23 to the height adjustment mechanism 30, the roller cover 23 drives the material dispensing mechanism 20 to move up and down, thereby achieving layer-by-layer and quantitative fertilizer dispensing. The rotating shaft 21 is connected to the hydraulic motor 24. In this embodiment, the height adjustment mechanism 30 includes a fixed rod 31 and a roller telescopic cylinder 32. The fixed rod 31 is fixedly connected to the roller cover 23 at one end and hinged to a carriage 43 at the other end. The roller telescopic cylinder 32 is hinged to the roller cover 23 at one end and hinged to the carriage 43 at the other end. In this way, the hydraulic rod of the roller telescopic cylinder 32 is extended and retracted to drive the fixed rod 31 to rotate about the carriage 43, thereby driving the material dispensing mechanism 20 to move up and down. The provision of the fixed rod 31 greatly improves the reliability of the up and down movement of the material dispensing mechanism 20. The sealing plate assembly 50 also includes a sealing plate telescopic cylinder 52, one end of the sealing plate telescopic cylinder 52 is hinged to the fertilizer box 10, and the other end is hinged to the sealing plate 51. One side of the sealing plate 51 is hinged to the bottom of the fertilizer box 10. The hydraulic rod of the sealing plate telescopic cylinder 52 is extended and retracted to rotate the sealing plate 51, thereby adjusting the opening and closing degree of the opening 11.

[0025] In the above technical solution, the fertilizer box 10 is set on the frame 12, and the frame 12 is fixed on the mobile equipment. When fertilizer needs to be loaded into the fertilizer box 10, the hydraulic rod of the sealing plate telescopic cylinder 52 is extended, thereby rotating the sealing plate 51 to open the opening 11, which is conducive to the fertilizer entering the fertilizer box 10; the hydraulic rod of the drum telescopic cylinder 32 is extended, driving the fixed rod 31 to rotate downward around the slide 43, thereby making the material diverting mechanism 20 in a lower position; the slide hydraulic motor 44 is started, and the slide hydraulic motor 44 drives the slide driving wheel 46 to rotate through the slide transmission component 45 until the slide driving wheel 46 drives the slide 43 and the material-dispensing mechanism 20 are near the opening 11; the hydraulic motor 24 is started, which drives the paddle 22 to rotate via the rotating shaft 21, dispensing the fertilizer into the fertilizer bin 10; the chute driving wheel 46 then drives the slide 43 and the material-dispensing mechanism 20 to slide into the interior of the fertilizer bin 10, thereby pushing the fertilizer into the fertilizer bin 10; the hydraulic rod of the drum telescopic cylinder 32 shortens, driving the fixed rod 31 to rotate upward around the slide 43, thereby raising the position of the material-dispensing mechanism 20 to begin loading the second layer of fertilizer; this process is repeated to continuously push the fertilizer into the fertilizer bin 10 layer by layer until the entire fertilizer bin 10 is full. During this process, the hydraulic rod of the sealing plate telescopic cylinder 52 continuously shortens, causing the sealing plate 51 to rotate upward and lift to a certain angle, sealing the lower layer of fertilizer to prevent it from leaking. When it is necessary to spread fertilizer, the hydraulic cylinder of the sealing plate telescopic cylinder 52 is extended, so that the sealing plate 51 rotates to open the opening 11, which is conducive to spreading the fertilizer outside the fertilizer box 10; the slide hydraulic motor 44 is started, and the slide hydraulic motor 44 drives the chute driving wheel 46 to rotate through the slide transmission component 45 until the chute driving wheel 46 drives the slide 43 and the material diverter mechanism 20 to be near the opening 11, pushing the fertilizer to the outside of the fertilizer box 10; the hydraulic motor 24 is started, and the hydraulic motor 24 drives the paddle 22 to rotate through the rotating shaft 21 to divert the fertilizer to the outside of the fertilizer box 10; after each layer of fertilizer is completely spread, the sealing plate 51 drops a certain angle, and the material diverter mechanism 20 drops a certain height, and then continues to spread the next layer of fertilizer until the fertilizer in the fertilizer box 10 is completely spread.
