DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example

[0033] like Figure 1-3 As shown, the utility model provides an automatic unloading mechanism for a salt raw material warehouse, comprising: a device base 1, a vibration motor 2, a unloading trough 3, a lifting cylinder 4, a buffer assembly 5, and a distribution trough 6. Support plates 100 extend upward at both ends of one side of the device base 1, the vibration motor 2 is vertically fixed on one of the support plates 100, and the output shaft of the vibration motor 2 is fixed with a support rod. A fixed groove 300 is provided on one side of the bottom of the unloading trough 3, and the top of the support rod contacts the fixed groove 300, and the support rod can rotate in the fixed groove 300. The lifting cylinder 4 is vertically arranged on the device base 1, and the buffer assembly 5 is arranged on the output shaft of the lifting cylinder 4. The upper end of the buffer assembly 5 is connected to the end of the bottom surface of the unloading trough 3 away from the fixed groove 300, and the distribution trough 6 is fixed on a support plate 100 away from the vibration motor 2, and the upper end opening of the distribution trough 6 is aligned with one side of the unloading trough 3. The vibration motor 2 is started to drive the support rod to drive the discharge trough 3 to vibrate, and the lifting cylinder 4 drives the discharge trough 3 to tilt slightly, so that the salt raw material in the discharge trough 3 can enter the distribution trough 6. When the salt raw material in the distribution trough 6 reaches the specified weight, the lifting cylinder 4 rises, causing the discharge trough 3 to tilt in the opposite direction, and the discharge trough 3 stops pouring salt raw materials into the distribution trough 6. The device can accurately control the discharge amount of salt raw materials. At the same time, the condensed salt raw materials discharged from the raw material bin are dispersed by the vibration motor 2.

[0034] It should be noted that one end of the feed chute 3 away from the distribution chute 6 is connected to the outlet of the salt raw material warehouse. When the lifting cylinder 4 rises so that the height of the end of the feed chute 3 close to the distribution chute 6 is higher than the other side, the other end of the feed chute 3 is connected to a baffle (not shown in the figure). The setting of the baffle makes the salt raw material in the feed chute 3 only enter the distribution chute 6 through the end close to the distribution chute 6.

[0035] In this embodiment, if Figure 3 As shown, the top of the support rod is hemispherical, and the fixed groove 300 is an arc-shaped structure. When the lifting cylinder 4 rises or falls, the support rod is movably connected to the fixed groove 300, so the support rod can rotate in the fixed groove 300. The structure is simple and the device has strong adaptability.

[0036] In this embodiment, the buffer assembly 5 includes: a first connecting plate 500, a buffer 510, and a second connecting plate 520. The first connecting plate 500 is fixed to the output end of the lifting cylinder 4. The buffers 510 are spaced apart on the upper surface of the first connecting plate 500. The second connecting plate 520 is horizontally arranged on the top surfaces of several buffers 510. The second connecting plate 520 is connected to the bottom surface of the chute 3. The buffer 510 includes: a limiting tube 511, a limiting rod 512, and a spring 513. The limiting tube 511 is fixed to the lower surface of the second connecting plate 520. The upper end of the limiting rod 512 is restricted in movement within the limiting tube 511. The lower end of the limiting rod 512 is fixed to the first connecting plate 500. The spring 513 is restricted to the outer periphery of the limiting rod 512. When the vibration motor 2 vibrates the chute 3, the buffer 510 is arranged so that the vibration generated by the chute 3 during the vibration process can be buffered by the buffer 510 and will not be directly transmitted to the lifting cylinder 4.

[0037] In this embodiment, a discharge port is set at the bottom of the distribution trough 6, and an opening and closing component 600 is set at the discharge port. The opening and closing component 600 includes: a closing column 601 and a rotating motor 602. The cross-section of the closing column 601 is a fan-shaped structure. The closing column 601 can be rotated and restricted in the discharge port. A rotating rod is set at the center of both ends of the closing column 601. The rotating rod passes through both sides of the discharge port, and the output shaft of the rotating motor 602 is connected to one of the rotating rods.

[0038] In this embodiment, it also includes: an adjusting tube 7 and an adjusting rod 8. The adjusting tube 7 is rotatably arranged on the top of the material distribution trough 6. The lower end of the adjusting rod 8 is restricted in the adjusting tube 7. The upper end of the adjusting rod 8 is rotatably connected to the edge of the discharge trough 3. The setting of the adjusting tube 7 and the adjusting rod 8 increases the stability of the connection of the material distribution trough 6. The rotatable setting of the adjusting tube 7 and the adjusting rod 8 allows the rotation of the discharge trough 3.
