DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] Reference Figure 1-3 A quantitative conveying device for packaging organic fertilizer comprises a weighing cylinder 1 and a base 2, wherein the weighing cylinder 1 is embedded in the base 2 and a pressure sensor 10 is installed between the weighing cylinder 1 and the base 2, a controller 3 is installed on the side wall of the weighing cylinder 1, a conveying port 4 is opened on the side of the weighing cylinder 1, and slide rails 5 are symmetrically arranged on both sides of the conveying port 4, and the slide rails 5 are fixedly and symmetrically installed on both sides of the weighing cylinder 1, and the conveying port 4 is respectively provided with a rotating plate 13 and a conveying trough 6, a slide plate 7 is slidably connected between the two slide rails 5, and a A push plate 8 is provided with an electric telescopic rod 9 on the upper side of the push plate 8, the electric telescopic rod 9 is fixedly mounted on the outer wall of the weighing cylinder 1 and the output end of the electric telescopic rod 9 is fixedly connected to the push plate 8, a fixed shaft 12 is fixedly mounted on the inner side of the weighing cylinder 1, a rotating plate 13 is rotatably mounted on the upper side of the fixed shaft 12, first supports 14 are symmetrically mounted on both sides of the rotating plate 13, a second support 15 is symmetrically mounted on the inner side of the slide plate 7, a connecting rod 16 is hinged between the first support 14 and the second support 15, and an adaptive component 17 is arranged on the inner side of the rotating plate 13.
[0023] Through the above structure, the pressure sensor 10 can sense the total pressure transmitted on the weighing cylinder 1, and feed back the pressure value to the controller 3. Then, the controller 3 can obtain the total mass of the organic fertilizer inside the weighing cylinder 1 by subtracting the mass of the overall components on the weighing cylinder 1 in combination with the internal program. Since the feedback of the pressure sensor 10 is real-time, the controller 3 can monitor the mass of the organic fertilizer inside the weighing cylinder 1 in real time. When the mass of the organic fertilizer reaches a preset value, it quantitatively delivers the organic fertilizer in the symmetrical measuring cylinder 1 by opening the delivery port 4.
[0024] In this embodiment, the adaptive component 17 includes a blocking plate 171, a first transverse plate 172 and a second transverse plate 173. The first transverse plate 172 is fixedly installed at the bottom of the blocking plate 171, and the second transverse plate 173 is fixedly installed at the bottom of the rotating plate 13. The blocking plate 171 is in sliding contact with the rotating plate 13. A telescopic rod 174 is connected between the first transverse plate 172 and the second transverse plate 173. A compression spring 175 is arranged inside the telescopic rod 174. A blocking strip 176 is installed on the inner side of the blocking plate 171.
[0025] Through the above structure, when the rotating plate 13 rotates upward, due to the circumferential geometric relationship, a gap will be generated between the rotating plate 13 and the inner wall of the weighing cylinder 1. At this time, the resilience of the compression spring 175 drives the telescopic rod 174 to push the blocking plate 171 inward, so as to adaptively fill the gap formed between the inner end of the rotating plate 13 and the inner wall of the weighing cylinder 1 during the rotation process, thereby ensuring that the rotating plate 13 always maintains a sealed contact with the inner wall of the weighing cylinder 1, and preventing the organic fertilizer from falling into the bottom of the weighing cylinder 1 through the gap.
[0026] In this embodiment, connecting pieces 61 are provided on both sides of the conveying trough 6 , and the connecting pieces 61 are screwed to the base 2 .
[0027] Through the above structure, the conveying trough 6 is fixed on the base 2 through the connecting piece 61, and its mass is borne by the structure of the base 2, and does not interfere with the entire weighing system.
[0028] In this embodiment, a plurality of balls 11 are rotatably mounted on the inner wall of the base 2 , the side wall of the weighing cylinder 1 is in rolling contact with the balls 11 , and four pressure sensors 10 are provided and respectively located at the four corners of the bottom of the weighing cylinder 1 .
[0029] Through the above structure, four pressure sensors 10 are provided and respectively located at the four corners of the bottom of the weighing cylinder 1, so that the bottom support of the pressure sensor 10 and the symmetrical measuring cylinder 1 is more stable. The pressure value transmitted on the weighing cylinder 1 is the sum of the pressures of the four pressure sensors 10. The setting of the ball 11 reduces the lateral friction between the side wall of the weighing cylinder 1 and the base 2, so that the sensing value of the pressure sensor 10 is more accurate.
[0030] In this embodiment, the electric telescopic rod 9 and the pressure sensor 10 are both electrically connected to the controller 3 .
[0031] Through the above structure, after the controller 3 senses through the pressure sensor 10 that the weight of the organic fertilizer inside the weighing cylinder 1 reaches a preset value, it starts the electric telescopic rod 9 to open the delivery port 4, thereby improving the degree of automation.
[0032] In this embodiment, a plurality of groups of telescopic rods 174 are evenly arranged between the first transverse plate 172 and the second transverse plate 173 , and the blocking strips 176 are cylindrical rubber strips.
[0033] Through the above structure, the sealing strip 176 is set to a cylindrical shape, so that the side of the sealing strip 176 can always maintain good contact with the weighing cylinder 1.
[0034] In the utility model, when in use, firstly, a preset value of quantitative delivery is input into the controller 3, and organic fertilizer is added into the weighing cylinder 1. The controller 3 monitors and calculates the weight of the organic fertilizer inside the weighing cylinder 1 in real time through the pressure sensor 10. When the weight of the organic fertilizer reaches the preset value input into the controller 3, the feeding is stopped, and the electric telescopic rod 9 is started to retract, which drives the slide plate 7 blocked on the outside of the delivery port 4 to slide up along the slide rail 5, and the delivery port 4 begins to open. At the same time, when the slide plate 7 slides up, the connecting rod 16 hingedly connected between the slide plate 7 and the rotating plate 13 drives the rotating plate 13 to rotate around the fixed shaft 12. Rotate, when the slide plate 7 slides to the upper side, the delivery port 4 is opened and the rotating plate 13 is in an inclined state, and the lowest point of the rotating plate 13 is located at the delivery port 4. Under the action of the inclined surface of the rotating plate 13, the organic fertilizer inside the weighing cylinder 1 slides into the conveying trough 6 to complete the quantitative delivery. At the same time, during the rotation of the rotating plate 13, the resilience of the compression spring 175 drives the telescopic rod 174 to push the blocking plate 171 inward, so as to adaptively fill the gap formed between the inner end of the rotating plate 13 and the inner wall of the weighing cylinder 1 during the rotation process, so as to prevent the organic fertilizer from falling into the bottom of the weighing cylinder 1 through the gap.

For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
