Description

Technical Field

[0001] The invention relates to the technical field of fertilizer processing, and in particular to an automatic and continuous fertilizer proportioning device. Background Art

[0002] Fertilizers are mainly used to provide plant nutrition to the soil. According to different soil conditions, people will adjust the fertilizer ratio, so it is necessary to design a ratio device.

[0003] The patent application number CN219308502U discloses a fertilizer proportioning device, which introduces basic fertilizer into the interior of a mixing barrel through a feed pipe, and then pours other raw materials into each measuring barrel according to the required proportion. The proportion of the poured raw materials can be measured by the scale thereon. After the proportioning is completed, the round rod can be rotated to drive the hollow rod to rotate. The rotation of the hollow rod causes the round block to slide along the arc groove, thereby driving the arc baffle to move. The proportioned raw materials enter the mixing barrel together through the perforation. The round rod is released and the arc baffle returns to its previous position through the force of the arc spring and the arc groove to block the perforation. The proportioning device discharges fertilizer by manually rotating the round rod. This proportioning method requires manual rotation of the round rod for multiple times during large-scale proportioning, which is relatively labor-intensive.

The torsion spring 44 is wound around the rotating block 43. The second storage box 45 is welded on the upper side of the first fixed frame 1. The lower side of the second storage box 45 is connected to a discharge pipe 46. The lower side of the second storage box 45 is slidably connected to a sliding discharge rod 47. After the rotating block 43 moves, it contacts the sliding discharge rod 47. The lower side of the discharge pipe 46 is connected to a first hose 48. The lower side of the second fixed frame 42 is slidably connected to a sliding nozzle 410. The first hose 48 is connected to the sliding nozzle 410. An air pump 49 is installed on the upper right side of the first fixed frame 1, and the air pump 49 is connected to the sliding nozzle 410.

[0034] Reference Figure 1 , Figure 2 , Figure 8 , Fig. 9 and Fig.10The adjusting mechanism 5 includes a fixed guide rail 51, a first screw rod 52, a second hose 53, a pressing plate 54, a slider 55, a first telescopic spring 56 and a sliding frame 57. The sliders of the two rodless cylinders 41 are both welded with fixed guide rails 51, and the two fixed guide rails 51 are both slidably connected with sliders 55, the lower sides of the sliders 55 are both connected with first telescopic springs 56, a sliding frame 57 is connected between the two first telescopic springs 56, and the slider 55 is slidably connected to the sliding frame 57. Three pressing plates 54 are evenly slidably connected to the second storage box 45, and the pressing plates 54 are all connected with second hoses 53, and there are three second hoses 53. The second hoses 53 are connected to the second storage box 45, and the pressing plates 54 are rotatably connected with first screw rods 52, and there are three first screws 52. The first screw 52 is threadedly connected to the sliding frame 57.

[0035] When people need to prepare fertilizers, they can use this automatic continuous fertilizer proportioning device. First, people rotate the first screw 52 according to the amount of fertilizer to be added, and control the sliding frame 57 to remain stationary, so that the pressing plate 54 moves adaptively and the second hose 53 stretches adaptively. When the pressing plate 54 moves to a suitable position, people loosen the first screw 52, ​​and people inject three different fertilizers into the second storage box 45 located on the lower side of the pressing plate 54 through the second hose 53. Then people manually rotate the rotating door 3 to a suitable angle and inject a suitable amount of water into the first storage box 2. After the injection is completed, people rotate the rotating door 3 in the opposite direction to the initial position, and then people start the rodless cylinder 41 and the air pump 49. The slider of the rodless cylinder 41 drives the rotating block 43 to move right. When the rotating block 43 on the front side moves to the right and contacts the sliding discharge rod 47, the rotating block 43 on the front side drives the sliding discharge rod 47 to move backward. When the rotating block 43 on the rear side moves to the right and contacts the sliding discharge rod 47, the rotating block 43 on the rear side rotates, and the torsion spring 44 on the rear side twists and deforms. When the rotating block 43 on the rear side continues to move to the right and away from the sliding discharge rod 47, the torsion spring 44 on the rear side resets and drives the rotating block 43 on the rear side to rotate and reset in the opposite direction. The sliding discharge rod 47 moves backward to open the second storage box 45, so that the fertilizer in the second storage box 45 flows into the sliding nozzle 410 through the discharge pipe 46 and the first hose 48, and the air pump 49 pressurizes the sliding nozzle 410 so that the sliding nozzle 410 sprays the fertilizer to In the water in the first storage box 2, the slider of the rodless cylinder 41 moves to the right, driving the second fixed frame 42 and the sliding nozzle 410 to move to the right, thereby achieving the effect of mobile spraying. At the same time, the slider of the rodless cylinder 41 moves to the right, driving the fixed guide rail 51 to move to the right, and then the slider 55 moves downward along the fixed guide rail 51, so that the slider 55 drives the sliding frame 57 to move downward through the first telescopic spring 56, so that the first screw 52 moves downward during the rotation, driving the pressing plate 54 to move downward, the second hose 53 stretches, and the fertilizer in the second storage box 45 is squeezed into the discharge pipe 46, thereby achieving the effect of discharge. When the fixed guide rail 51 continues to move to the right and the sliding frame 57 cannot continue to move to the right, the first telescopic spring 56 is compressed. After the slider of the rod cylinder 41 moves to the right to a suitable position, people can control the slider of the rodless cylinder 41 to move to the left, so that the rotating block 43 moves to the left. When the rotating block 43 on the rear side moves to the left and contacts the sliding discharge rod 47, the rotating block 43 on the rear side drives the sliding discharge rod 47 to move forward to close the second storage box 45. When the rotating block 43 on the front side moves to the left and contacts the sliding discharge rod 47, the rotating block 43 on the front side rotates, and the torsion spring 44 on the front side is torsionally deformed. When the rotating block 43 on the front side continues to move to the left away from the sliding discharge rod 47, the torsion spring 44 on the front side resets and drives the rotating block 43 on the front side to rotate and reset in the opposite direction. The slider of the rodless cylinder 41 moves to the left, driving the second fixed frame 42 and the sliding nozzle 410 to move to the left.At the same time, the slider of the rodless cylinder 41 moves to the left, driving the fixed guide rail 51 to move to the left, causing the slider 55 to move upward, and then the first telescopic spring 56 is reset. Then, the slider 55 drives the sliding frame 57 to move upward through the first telescopic spring 56, causing the first screw rod 52 to rotate in the opposite direction and move upward, thereby causing the pressing plate 54 to move upward and the second hose 53 to shorten. When the slider of the rodless cylinder 41 moves to the left to the initial position, people turn off the rodless cylinder 41 and the air pump 49, and then people export the prepared fertilizer in the first storage box 2 for use.

The material discharge rack 73 is slidably connected to the connecting rod 72, and the connecting rod 72 is connected to the sliding material discharge rod 47.

[0040] The movement of the second fixed frame 42 drives the rotating shaft 63 to move, thereby causing the roller 62 and the full gear 64 to move. Since the full gear 64 is meshed with the rack 61, the full gear 64 rotates during the movement, causing the rotating shaft 63 and the roller 62 to rotate. The rotating roller 62 mixes the water and fertilizer evenly, thereby achieving a stirring effect.

[0041] First, people inject an appropriate amount of fertilizer into the third storage box 71. In the initial state, the connecting rod 72 overlaps with the discharge rack 73, so that the fertilizer flows into the second storage box 45 through the discharge rack 73. The sliding discharge rod 47 moves backward to drive the connecting rod 72 to move backward, so that the connecting rod 72 closes the discharge rack 73. The sliding discharge rod 47 moves forward to drive the connecting rod 72 forward, so that the discharge rack 73 is opened.

[0042] When people need to adjust the height of the first storage box 2, they can manually rotate the rotating frame 83, so that the bevel gear set 82 rotates, and the second screw 81 rotates to drive the first storage box 2 to move, thereby achieving the effect of adjusting the height. When the first storage box 2 is adjusted to a suitable height, people can release the rotating frame 83.

[0043] The movement of the sliding nozzle 410 drives the fixed rod 91 to move. When the fixed rod 91 moves to the groove part of the second guide rail 93, the fixed rod 91 drives the sliding nozzle 410 to move downward. When the fixed rod 91 moves to the raised part of the second guide rail 93, the fixed rod 91 drives the sliding nozzle 410 to move upward. By changing the spraying height of the fertilizer, the fertilizer is mixed more evenly.
