DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 The utility model provides a technical solution for a sand and gravel sorting vibrating screen assembly: it includes a base structure 1, one end of the base structure 1 is fixedly connected to a connecting frame 2, the upper and lower ends of the connecting frame 2 are respectively fixedly connected to an upper mounting plate 3 and a lower mounting plate 4, the surfaces of the upper mounting plate 3 and the lower mounting plate 4 are respectively movably connected to a first driving disk 5 and a second driving disk 6, the surface of the first driving disk 5 is movably connected to a driving arm 22, a screening structure 7 is movably arranged above the base structure 1, the bottom end of the screening structure 7 is fixedly connected to a supporting structure 8, and the driving arm 22 is movably connected to the outer end of the screening structure 7 at the same time.

[0022] like Figure 1-2 As shown, the base structure 1 includes a fixedly connected base body 9 and a first discharge plate 10 at the bottom of its front side. The base body 9 is also fixedly connected with a guide structure inside. The guide structure includes a fixedly connected guide rod 13 and mounting seats 12 at both ends thereof. The guide rod 13 is movably sleeved with a spring 14 at the outer end. The mounting seat 12 is also fixedly connected to the inner wall of the base body 9. The guide rod 13 and the mounting seat 12 are laterally matched. Two groups are longitudinally distributed above the base body 9. The base body 9 is rectangular as a whole, and a guide portion 11 is obliquely provided on the inner wall of the rear end thereof. The guide portion 11 is also located behind the guide rod 13. The base body 9 cooperates with the first discharge plate 10 to achieve the effect of storing and exporting a part of the selected sand and gravel. The guide rod 13 is used to facilitate the overall lateral movement and adjustment of the screening structure 7 along the upper side of the base body 9. The spring 14 is used to assist the vibration of the laterally adjusted screening structure 7, and at the same time, a buffering effect is achieved.

[0023] When the screening structure 7 is driven by the first driving disk 5 and the second driving disk 6 to move, it moves back and forth along the guide rod 13 above the base body 9. The screening structure 7 squeezes the spring 14 during the movement and adjustment process. The transversely arranged spring 14 only needs to be subjected to the lateral external force brought by the active screening structure 7, and has good buffering and auxiliary effects, thereby ensuring the sorting efficiency.

[0024] like Figure 1-2 As shown, the screening structure 7 includes an inclined screening frame 15 and a second discharge plate 16 at both ends thereof and a connecting support 18. A screen plate 17 is fixedly connected to the inner bottom of the screening frame 15. The connecting support 18 and the driving arm 22 are movably connected. The second discharge plate 16 is inclined, and the supporting structure 8 has two groups distributed laterally.

[0025] like Figure 2-3 As shown, the support structure 8 includes a support platform 19 arranged in a trapezoidal shape and a connecting arm 20 fixedly connected to its bottom, the bottom end of the connecting arm 20 is fixedly connected to a guide cylinder 21 which is movably adjusted with the guide rod 13, and two groups of connecting arms 20 and guide cylinders 21 are matched and arranged, and are longitudinally distributed along the bottom of the support platform 19. The support platform 19 and the connecting arm 20 can support the screening structure 7 as a whole, and the guide cylinder 21 movably sleeved with the guide rod 13 can facilitate the sliding adjustment of the screening structure 7 as a whole along the guide rod 13, and the screen plate 17 and the second discharge plate 16 can be used to sort and discharge sand and gravel.

[0026] The second driving disk 6 rotates, and the first driving disk 5 is driven to rotate through the transmission belt between the second driving disk 6 and the first driving disk 5. The rotation of the first driving disk 5 drives the driving arm 22 eccentrically connected to it to swing back and forth. The driving arm 22 simultaneously drives the screening structure 7 movably connected to it to move back and forth along the guide rod 13 as a whole, and then completes the screening operation on the sand and gravel placed on the screening frame 15. A part of the screened sand and gravel passes through the screen plate 17 and falls into the base body 9, and is discharged through the first discharging plate 10, while the other part is directly discharged outward along the second discharging plate 16.

[0027] like Figure 1 As shown, the first driving disk 5 and the second driving disk 6 are connected via a belt drive, a driving motor is provided at the outer end of the second driving disk 6 , and the driving arm 22 and the first driving disk 5 are eccentrically connected.

[0028] The working principle of the utility model is as follows: when the device is in use, the user places the sand and gravel in the screening frame 15, and then the first driving disk 5 rotates, and the driving arm 22 drives the screening frame 15 to move back and forth along the guide rod 13 for adjustment to complete the screening operation of the sand and gravel. The screened sand and gravel can be simultaneously discharged outward through the corresponding two groups of discharge plate structures. The user can pre-arrange a storage device at the bottom of the two groups of discharge plates to synchronously store the screened sand and gravel. In the process of sorting sand and gravel, the spring 14 of the device is arranged horizontally, and cooperates with the guide rod 13 to have good force stability, which can effectively ensure its service life, and the overall device does not require a vibration motor, has a simple structure and low cost, and has good practicality.

[0029] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
