[0022] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Please refer to Figures 1-4 The present application provides a technical scheme: a plastic particle storage device, the storage tank body 1 top is equipped with the feed bin 1.1, the storage tank body 1 bottom surface is fixed to the top end of the undercarriage 2 near the outer edge position.

[0024] The spiral discharging mechanism 3 includes the vertical cylinder 3.1 that is vertically slidably sleeved in the middle part of the bottom surface of the storage tank body 1 and has an open top end, the spiral blade shaft 3.2 that is rotatably installed in the inner cavity of the vertical cylinder 3.1, the motor 3.3 that is fixed to the bottom surface of the vertical cylinder 3.1 and has a power output shaft top end fixedly connected with the bottom end of the spiral blade shaft 3.2, and the discharging pipe 3.4 that has one end fixedly sleeved to the bottom end of the side wall of the vertical cylinder 3.1. Among them, the inner cavity top end middle part of the vertical cylinder 3.1 is provided with a hemisphere 3.6, the bottom end outer wall of the hemisphere 3.6 is fixedly connected with the top end inner circumferential wall of the vertical cylinder 3.1, and the top end of the spiral blade shaft 3.2 is rotatably sleeved to the bottom surface of the hemisphere 3.6. The hemisphere 3.6 not only can improve the support strength of the spiral blade shaft 3.2, but also can better guide the plastic particles to the top opening of the vertical cylinder 3.1. The bottom end outer circumferential wall of the vertical cylinder 3.1 is fixedly provided with the support plate 3.5 on both sides along the radial direction.

[0025] The telescopic cylinder 5 is used to drive the vertical cylinder 3.1 to move vertically relative to the storage tank body 1. Among them, the bottom end of the piston cylinder of the telescopic cylinder 5 is fixed to the bottom surface of the support plate 3.5, and the top end of the piston rod of the telescopic cylinder 5 is fixedly connected with the bottom surface of the storage tank body 1 after penetrating through the support plate 3.5.

[0026] The guide support 4 includes the sleeve ring 4.1 that is slidably sleeved with the vertical cylinder 3.1, the support plate strip 1 4.2 that is fixedly provided on the outer circumferential wall of the sleeve ring 4.1 along the radial direction, and the connecting plate 1 4.3 that is provided on the outer end of the support plate strip 1 4.2 and is fixedly connected with the inner circumferential wall of the storage tank body 1. That is, the sleeve ring 4.1 is used to provide a guiding and supporting effect when the vertical cylinder 3.1 moves up and down, so as to ensure the stable lifting movement of the vertical cylinder 3.1.

[0027] The capping piece 6 comprises a hemispherical shell 6.1 arranged in the middle of the top end of the inner cavity of the storage tank body 1, a ring body 6.2 fixed to the outer edge of the bottom end of the hemispherical shell 6.1 and matched with the top end of the vertical cylinder 3.1 in a sliding sleeve connection, a support plate strip 6.3 radially fixed to the outer peripheral wall of the ring body 6.2, and a connecting plate 6.4 arranged at the outer end of the support plate strip 6.3 and fixedly connected with the top part of the inner peripheral wall of the storage tank body 1. That is, during the feeding or storage of the plastic particles, the top end of the vertical cylinder 3.1 is sleeved in the ring body 6.2, and the hemispherical shell 6.1 seals the open top end of the vertical cylinder 3.1, so as to prevent the plastic particles from flowing into the vertical cylinder 3.1 during the feeding and storage, thereby preventing the large resistance of the spiral blade shaft 3.2 from starting to rotate during the discharging, that is, preventing the load starting of the motor 3.3. In addition, the arrangement of the hemispherical shell 6.1 will not cause the plastic particles to stagnate at the top thereof.

[0028] In summary, during the feeding, the piston rod of the telescopic cylinder 5 is retracted, so that the spiral discharging mechanism 3 is located at the highest position, that is, the top end of the vertical cylinder 3.1 is sleeved in the ring body 6.2, and then the plastic particles are poured into the storage tank body 1.1 through the feeding hopper 1.1.

[0029] When the discharging is needed, the motor 3.3 is started, and the motor 3.3 drives the spiral blade shaft 3.2 to rotate. The piston rod of the telescopic cylinder 5 is slightly elongated, so that the top end opening of the vertical cylinder 3.1 is separated from the ring body 6.2, so that the plastic particles at the top gradually flow into the vertical cylinder 3.1, and the rotating spiral blade shaft 3.2 pushes the flowing plastic particles downward, and finally discharges from the discharging pipe 3.4; as the height of the plastic particle accumulation slowly decreases, the telescopic cylinder 5 gradually elongates the piston rod, so that the spiral discharging mechanism 3 gradually moves downward, so that the top opening of the vertical cylinder 3.1 is always close to the top surface of the plastic particle accumulation, so as to ensure that the plastic particles smoothly flow into the vertical cylinder 3.1 from the top opening, so as to realize the high-efficiency discharging process.
