[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] See appendix Figures 1 to 3 This utility model discloses a vibrating feeder for sea sand desalination with shock absorption function, comprising:

[0037] Body 1;

[0038] Support plate 4, the panel of support plate 4 is arranged parallel to the bottom wall of body 1 and installed on the outer wall of body 1, and positioning holes 41 are provided on the panel of support plate 4.

[0039] The vertical damping mechanism 2 includes a fixed base 21, a limiting rod 22, and a damping spring 23. The fixed base 21 is located below the support plate 4. The upper outer wall of the limiting rod 22 slides against the inner wall of the positioning hole 41, and the lower end is vertically fixed to the top surface of the fixed base 21. The damping spring 23 is sleeved on the limiting rod 22, and its two ends abut against the bottom surface of the support plate 4 and the top surface of the fixed base 21, respectively.

[0040] The transverse damping mechanism 3 includes a support base 32 and a buffer spring 33. The support base 32 is detachably connected to the upper end of the limiting rod 22 and located in the positioning hole 41. The buffer spring 33 is arranged perpendicular to the damping spring 23 and its two ends slide against the side wall of the support base 32 and the inner wall of the positioning hole 41, respectively.

[0041] The machine body 1 is a box structure with openings at the top and front. The machine body 1 is arranged at an angle along the direction of its front opening. A liner 13 is fixed to the inner bottom wall of the machine body 1 relative to its rear end, and multiple grate bars 14 are fixed to the inner bottom wall of the machine body 1 relative to its front end. A discharge gap is formed between two adjacent grate bars 14. A vibrator is fixed to the outer bottom wall of the machine body 1.

[0042] like Figure 1 As shown, the machine body generates excitation force through the vibrator, thereby realizing the vibration of the machine body. The vibrator completes the work of the feeder. The liner receives the raw material. Under the action of the excitation force, sand and gravel of different particle sizes will be separated. The desalination and separation of sea sand is completed through the discharge gap formed between multiple grate bars.

[0043] In this embodiment, the vertical damping mechanism and the horizontal damping mechanism are integrated and installed on both sides and the rear end of the machine body, respectively. Multiple positioning holes are provided on the support plate at the rear end, while only one positioning hole is provided on the support plates on both sides of the machine body.

[0044] In this embodiment, the fixing base 21 is a reinforced concrete base, and the top surface of the fixing base 21 is provided with expansion bolts. The lower end of the limiting rod 22 is bolted to the expansion bolts.

[0045] The fixed base serves as the mounting base for the feeder, and integrates the vertical and horizontal vibration damping mechanisms. The reinforced concrete structure ensures that the fixed base has sufficient strength.

[0046] A damping spring is fitted on the outer wall of the limit rod. The buffer spring is located in the positioning hole and can slide up and down along the positioning hole. The support base is located at the top of the limit rod. When the feeder vibrates vertically, the transverse damping mechanism slides up and down along the positioning hole with the vertical vibration, without affecting the vertical damping capacity of the damping spring.

[0047] In other specific embodiments, to ensure the horizontal freedom of the buffer spring and prevent it from bending, the lateral damping mechanism 3 further includes a ring 31, which is fitted around the outer periphery of the support base 32. The ring 31 has a slot; the side wall of the support base 32 has a countersunk hole corresponding to the slot. The axis of the buffer spring 33 is arranged perpendicular to the damping spring 23 and passes through the slot, with one end of the buffer spring 33 inserted into the countersunk hole. The slot on the ring and the countersunk hole on the support base provide two-point support for the buffer spring, effectively ensuring its horizontality.

[0050] To further optimize the above technical solution, the body 1 includes a mounting plate 11 and a wing plate 12. The mounting plate 11 is fixed to the outer wall of the body 1. A through hole corresponding to the positioning hole 41 is opened on the panel of the mounting plate 11. The support plate 4 is bolted to the bottom surface of the mounting plate 11. There are two wing plates 12, which are respectively fixed on both sides of the top surface of the mounting plate 11. The two wing plates 12 and the mounting plate 11 form a cavity. The ring sleeve 31 is located in the positioning block 41 and the through hole, and its lower end face abuts against the upper end face of the limiting rod 22. Its upper end is exposed on the top surface of the mounting plate 11. A threaded sleeve 7 is screwed onto the outer wall of the upper end of the ring sleeve 31.

[0051] As shown in the figure, the outer wall of the machine body forms a mounting base with a cavity through the mounting plate and the support plate. The support plate is bolted to the bottom surface of the mounting plate. The ring sleeve passes through the through hole on the mounting plate and the positioning hole on the support plate. The lower end face of the ring sleeve abuts against the upper end face of the limit rod. The upper end of the ring sleeve is screwed with a threaded sleeve. The threaded sleeve can ensure that the ring sleeve is stable in the positioning hole and the through hole, prevent the ring sleeve from tilting, ensure that the ring sleeve and the support base are arranged coaxially, and can support the buffer spring through the slot and countersunk hole.

[0052] To further optimize the above technical solution and prevent sand and gravel particles from entering the positioning hole and getting stuck in the spring coil of the buffer spring, thus affecting the compression of the buffer spring, a flexible sleeve 34 is also included. The flexible sleeve 34 is sleeved on the outer periphery of the buffer spring 33, and the two ends of the flexible sleeve 34 slide against the side wall of the support base 32 and the inner wall of the positioning hole 41, respectively.

[0053] To further optimize the above technical solution, prevent the damping spring from extending into the positioning hole, and ensure that the functions of the horizontal damping mechanism and the vertical damping mechanism do not interfere with each other, an annular pad 6 is also included. The pad 6 is fixed on the bottom surface of the support plate 4 around the positioning hole 41, and the top of the damping spring 23 abuts against the bottom surface of the pad 6.

[0054] To further optimize the above technical solution and achieve coaxial installation of the support base and the limiting rod, the upper end of the limiting rod 22 is provided with a groove, the side wall of the groove is provided with an internal thread, and the lower end of the support base 32 is provided with an external thread that mates with the internal thread.

[0055] The support seat is a cylindrical seat, coaxially arranged with the limiting rod. The outer diameter of the support seat is smaller than the outer diameter of the limiting rod, and the outer diameter of the ring is larger than the outer diameter of the support seat but smaller than the outer diameter of the limiting rod.

[0056] In some other specific embodiments, in order to ensure the multi-dimensional shock absorption capability of the feeder, multiple sets of buffer springs can be provided, and the multiple sets of buffer springs are arranged in an array within the positioning holes.

[0057] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments.
