The existing vibrating screens are mostly based on screen type, and there are the following problems in use:

[0003] (1) Walnuts are mostly irregularly shaped and round in appearance, which makes them unsuitable for sieves and results in poor screening effects;

[0004] (2) The existing screen roller vibrating screen is more suitable for this application scenario, but the screen rollers are all fixed and inconvenient to replace. When facing walnuts of different types and origins, it is impossible to make timely adjustments to make them meet the collection requirements, and the applicability is poor. Utility Model Content

[0005] The utility model provides a screening device for walnut storage and feeding, aiming to solve the problems of poor screening effect of the screen mesh and poor applicability caused by the fixing of the screen roller in the above-mentioned existing vibrating screen during the grading screening process.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A screening device for walnut storage and feeding, comprising a mounting frame, a linear vibrating screen and a spring support, wherein a screen box of the linear vibrating screen is obliquely arranged on the mounting frame through the spring support, and the bottom of the screen box forms an elastic support cooperation with the mounting frame through the spring support;

[0008] A plurality of screening roller mechanisms evenly spaced in the vertical direction are detachably provided in the screen box through an installation mechanism.

A plurality of discharge ports are provided on the screen box, and the number and positions of the discharge ports correspond one-to-one to the number and positions of the screening roller mechanisms, and the bottom of the screening roller mechanism is flush with the top of the corresponding discharge port.

When the screen roller mechanism slides in along the corresponding discharge port, the two sides of the screen roller mechanism form a detachable fixed installation fit with the screen box through the corresponding two rows of mounting mechanisms.

[0011] Furthermore, each of the screening roller mechanisms includes a square mounting frame, the long side of the mounting frame is inclined along the inclination direction of the screen box, a plurality of screening rollers are arranged in the mounting frame, the screening rollers are evenly spaced along the wide side of the mounting frame, and the axial direction of the screening rollers is parallel to the long side of the mounting frame, and both ends of the roller shaft of the screening roller are rotatably matched with the wide side of the mounting frame on the corresponding side through bearings.

[0013] Specifically, the sizes of the screening rollers are all the same, and the intervals between adjacent screening rollers of the upper screening roller mechanism are greater than the intervals between adjacent screening rollers of the lower screening roller mechanism.

[0014] More specifically, each of the mounting mechanisms includes a limit plate arranged relative to and in parallel, the limit plate cooperates with the side wall of the screen box to form a mounting groove, and the mounting groove is parallel to the long side of the mounting frame of the corresponding screen roller mechanism, the long side of the mounting frame of the corresponding screen roller mechanism can be slidably embedded in the mounting groove, and the long side of the mounting frame and the limit plate form a detachable fixed fit through fastening bolts.

[0030] A plurality of screening roller mechanisms 7 evenly spaced in the vertical direction are detachably provided in the screen box 4 through an installation mechanism 8. The screening distance of the screening roller mechanisms 7 decreases step by step from top to bottom to form a graded screening coordination, and the screening roller mechanisms 7 are all synchronously tilted along the tilt direction of the screen box 4. A plurality of discharge ports 6 are provided on the screen box 4, and the number and positions of the discharge ports 6 correspond one-to-one to the number and positions of the screening roller mechanisms 7, and the bottom of the screening roller mechanisms 7 is flush with the top of the corresponding discharge ports 6.

[0031] Embodiment 1 provides a screening device for walnut storage and feeding, which performs vibration screening through a linear vibrating screen 2 installed on a mounting frame 1, and walnuts of different sizes are screened and sorted and stored as raw materials for preparing different products. After the walnuts enter the vibrating screen, they are moved toward an inclined side through the vibrating screening, and finally enter the conveyor belt of the corresponding storage mechanism from the corresponding discharge port 6. Because the shape of the walnuts is uneven, a screening roller mechanism 7 is used to screen the walnuts. The screening size is controlled by the spacing between the screening rollers 703. From top to bottom, there are multiple layers of screening roller mechanisms 7 arranged at equal intervals, and the spacing between the screening rollers 703 of the screening roller mechanisms 7 gradually decreases to form hierarchical screening, with the largest one on the top layer and the smallest one on the bottom layer, which is convenient for screening and collecting walnuts. At the same time, the screening roller mechanism 7 can enter and exit the screen box 4 from the discharge port 6, and can be installed and disassembled through the corresponding mounting mechanism 8, so as to facilitate the replacement of the screening roller mechanism 7, thereby adjusting the screening size, so that it is convenient to apply to walnuts of various types and origins, easy to use, and enhanced applicability.

[0032] As a preferred embodiment 1, the screen box 4 is an open box, a feed inlet 5 is provided on a higher side of the screen box 4, and a discharge port 6 is provided on a lower side of the screen box 4.

[0033] During feeding, the walnuts are directly delivered to the feed port 5 through the conveying mechanism. The feed port 5 and the screen box 4 are synchronously tilted at the same inclination angle. The walnuts automatically roll into the screen box 4 through the inclination angle, and are screened while rolling in the screen box 4, and finally fall out from the corresponding discharge port 6.

[0034] As a preferred embodiment 2, baffles are provided on both sides of the feed port 5 and the discharge port 6 to prevent the walnuts from rolling out from both sides during feeding and discharging, thereby playing a limiting role.

[0035] As a preferred embodiment 3, each of the sieve roller mechanisms 7 corresponds to a plurality of mounting mechanisms 8 arranged in two rows, and each row of mounting mechanisms 8 is arranged at equal intervals along the inclination direction of the sieve box 4. When the sieve roller mechanism 7 slides in along the corresponding discharge port 6, the two sides of the sieve roller mechanism 7 just form a detachable fixed installation match with the sieve box 4 through the corresponding two rows of mounting mechanisms 8.

The screening rollers 703 are evenly spaced along the wide side of the mounting frame 701, and the axial direction of the screening rollers 703 is parallel to the long side of the mounting frame 701, and both ends of the roller shaft of the screening roller 703 are rotatably matched with the wide side of the mounting frame 701 on the corresponding side through bearings 702.

When walnuts fall on the screening roller mechanism 7, the walnuts will fall into the gaps between the screening rollers 703 for screening due to the curved surfaces of the screening rollers 703. The screening size is controlled by the spacing of the screening rollers 703. When the size of the walnuts is not larger than the spacing of the screening rollers 703, the walnuts will fall from the gaps into the next-level screening roller mechanism 7 for hierarchical screening, and when the size of the walnuts is larger than the spacing of the screening rollers 703, they will slide along the inclination direction of the gaps and finally be discharged from the corresponding discharge port 6.

[0040] As a preferred embodiment 7, the outer wall of the mounting frame 701 is coaxial with the inner wall of the screen box 4. A gap between the mounting frame 701 and the screen box 4 is avoided, the integrity of the screening is ensured, and the mounting frame 701 is easy to install.

[0041] As a preferred embodiment 8, the sizes of the screening rollers 703 are the same, and the interval between adjacent screening rollers 703 of the upper screening roller mechanism 7 is larger than the interval between adjacent screening rollers 703 of the lower screening roller mechanism 7, so as to ensure the effect of hierarchical screening.

When the corresponding screen roller mechanism 7 enters, the long side of the mounting frame 701 passes through all the overlapping mounting grooves 802 in sequence until the wide side abuts against the screen box 4. At this time, each limit plate 801 and the limit plate 801 at the corresponding position are fixed and installed in sequence by tightening the bolts 804.

[0045] As a preferred embodiment 11, there is a gap between the screening roller 703 located on the side and the long side of the mounting frame 701, and the gap is the same as the gap between adjacent screening rollers 703, which facilitates the installation of the fastening bolts 804 without affecting the overall screening process.

[0052] The utility model provides a screening device for walnut storage and feeding. Through a linear vibrating screen 2 installed on a mounting frame 1, vibrating screening is performed, walnuts of different sizes are screened and sorted and stored as raw materials for preparing different products. After the walnuts enter the vibrating screen, they are moved toward an inclined side through the vibrating screening, and finally enter the conveyor belt of a corresponding storage mechanism from a corresponding discharge port 6.
