Description

Technical Field

[0001] The utility model relates to millet screening equipment, and specifically to a millet raw material screening machine. Background Art

[0002] The process of separating broken and scattered materials into different particle sizes through one or several layers of sieve surfaces is called screening. A screening machine is a vibrating screening mechanical device that uses the relative movement between bulk materials and the sieve surface to allow some particles to pass through the sieve holes and classify materials such as sand, gravel, and crushed stones into different levels according to particle size. The screening process of a screening machine is generally continuous. After the screening raw materials are fed onto the screening machine (abbreviated as the sieve), the materials smaller than the sieve hole size pass through the sieve holes and are called the undersize product; the materials larger than the sieve hole size are continuously discharged from the sieve surface and are called the oversize product.

[0003] After retrieval, it is found that the content of a new dry sand screening machine with the application number CN201621417063.8 is as follows: The utility model discloses a new dry sand screening machine, which is characterized in that: the main part of the screening machine is an open box with an open opening as the inlet of the screening machine. Two eccentric wheel type vibration motors are installed on the main body of the screening machine. A brush screen is installed in the middle position inside the main body of the screening machine. The middle position at the bottom end of the main body of the screening machine is provided with an outlet of the screening machine, and a dust removal device is provided at the outlet position of the screening machine; support fixing rods are provided at the four corner positions of the main part of the screening machine. The advantages of the utility model are: firstly, by setting a buckle to fix the brush screen on the screening machine, it greatly solves the trouble of replacing the brush screen before, greatly improves the efficiency and is convenient for employees to operate; secondly, replacing the spring with a pneumatic shock absorber has good shock absorption effect and low noise; thirdly, a dust removal device is arranged around the outlet of the screening machine, which does not pollute the environment, and the substances collected in this part can also be recycled and reused;

[0004] When usually making desired millet foods with millet as the raw material, sometimes the millet raw materials collected after screening through a vibrating sieve are of the same size, and other substances mixed in the millet are screened out, so that the foods made with millet as the raw material later will be more delicious. However, the conventional screening method is usually to manually use a sieve or a dustpan to screen the millet back and forth. This screening method is very laborious and has low efficiency, and cannot meet the food raw materials required when only making mass-produced millet. Content of the Utility Model

[0037] Please refer to Figures 1 - 7 , this embodiment proposes a millet raw material screening machine, including a support mechanism 1, a screening mechanism 2, and a transmission mechanism 3 for transmission;

[0038] The support mechanism 1 is used to support on the ground, separate the screening mechanism 2 from the ground, and the transmission mechanism 3 picks up the raw materials that have been screened and then transports them to the outside for storage.

[0039] The support mechanism 1 includes an access base 11 supported on the ground. The top of the access base 11 is connected with a buffer vertical rod 12 for support. The top ends of several buffer vertical rods 12 are installed with a steel spring cushion plate 13. The top of the steel spring cushion plate 13 is installed with a buffer steel spring 14. The top of the buffer steel spring 14 is provided with a trapezoidal seat 15.

[0040] A square frame 16 is surrounded by the inner side wall of the buffer vertical rod 12.

[0041] In this embodiment: The screening mechanism 2 includes a control box 21 supported on the inner side wall of the trapezoidal seat 15. The top of the box body of the control box 21 is provided with a screening slot 22. The bottom of the slot of the screening slot 22 is provided with a discharge air duct 23 for discharging materials. The inner part of the slot of the screening slot 22 is installed with a bottom layer screening mesh plate 24.

[0042] The adopted bottom layer screening mesh plate 24 and the corresponding discharge air duct 23 cooperate with each other to further discharge the specifically screened materials.

[0043] In this embodiment: A plurality of circular openings 25 are successively formed on the surface of the bottom screening mesh plate 24. The bottom screening mesh plate 24 matches the bottom screening mesh plate 24 in terms of size.

A lifting buckle is provided at the top of the L-shaped bracket 294. A feeding slot for toggling is installed in the middle of the top of the lifting buckle. A feeding hopper is formed in the middle of the top of the support telescopic cylinder.

[0048] Based on the support effects of the toggling roller shaft and the designated L-shaped bracket 294, an expansion in the corresponding hinge structure aspect is achieved.

[0049] In this embodiment: An excitation mechanism 4 is installed at the bottom of the bottom screening mesh plate 24. The excitation mechanism 4 includes an exciter 41 installed on the bottom surface of the control box 21. Excitation heads 43 are provided on both side edges of the vibration end of the exciter 41 and the bottom of the upper vibration bracket 42 above. The sensing end of the excitation head 43 is inductively connected to the surface of the rear vibration bracket 42.

[0050] Among the support effects of the adopted excitation heads 43 and the vibration bracket 42, the vibration conduction of the exciter 41 is completed, and the vibration conduction is carried out by using the vibration bracket 42 and the state inside the specific control box 21.

[0051] In this embodiment: The back surface of the vibration bracket 42 is fitted and connected to the bottom of the control box 21. On the top of the box body of the control box 21, a number of screening mechanisms 5 for screening fine millet materials are arranged in sequence. The screening mechanism 5 includes a lifting vertical rod 51 fitted and installed on the top of the control box 21. On the side wall of the rod body of the lifting vertical rod 51, there is a cross bracket 52 for adjustment. In the middle of the cross bracket 52, a number of fitting screening plates 53 are installed. On the top surface of the fitting screening plate 53, a number of lifting plates 54 for classified screening rotation are arranged in sequence.

[0052] The combination of the screening plates 53 is carried out by fitting the adopted lifting vertical rod 51 and the specific cross bracket 52.

[0053] In this embodiment: A transmission mechanism 3 is installed at the bottom of the discharge air duct 23. The transmission mechanism 3 includes a transmission bracket 31 fitted and installed at the discharge port position of the discharge air duct 23. In the middle of the top end of the transmission bracket 31, a transmission roller shaft 32 is installed. On the surface of the transmission roller shaft 32, there is a crawler, and a material distribution guide plate 33 is installed on the surface of the crawler.

[0054] In the introduced state of the adopted transmission roller shaft 32 and the material distribution guide plate 33, the corresponding L-shaped bracket 294 shares the support.

[0055] During specific use, Step 1: Feeding

[0056] First, the user further raises and adjusts the lifting plate 54 above based on the extension state of the rod body of the corresponding link rod 293 in the slot direction of the screening slot 22 opened above the square frame 16. In addition, the area of the multiple layers of lifting plates 54 above is shared. Using the corresponding cross brackets 52 in the plate surface area of the multiple layers of lifting plates 54 below, after multiple specific filtering and screening structures share, the classification is carried out using the spaced lifting plates 54, realizing the vibration screening between different fine materials. Based on the hinged state of the specific cross bracket 52, the interval distance is moved upward;

[0057] After unfolding, the user needs to face the sharing state of the plate surface of the lifting plates 54 in between, realizing the vibration screening on the corresponding lifting plates 54.

[0058] Step 2: Vibration screening;

[0059] This process is based on the delivery from the bottom of the control box 21 housing. After that, the operator starts the vibrator 41. Then, the vibration generated by the vibrator 41 will be transmitted to the vibration head 43, and the vibration head 43 will synchronously drive the replacement and expansion of multiple control box 21 housings. Finally, after layer-by-layer screening, the materials will be distributed down to the position of the control box 21. After the feeding, when it reaches the area of the discharge air duct 23 at the bottom, by means of the axial deflection rotation of the transmission rollers 32 at both ends, the state of the plate surfaces of the multiple material guiding plates 33 above is made to fit and achieve front-back transfer, and the corresponding sorting and transfer of the materials are realized by means of the corresponding multiple sharing structures;

[0060] Step 3: Serve as a buffer during the vibration stage;

[0061] This process utilizes the extended state of the rods of multiple buffer vertical rods 12 corresponding to the padding state of the steel spring pads 13 and the buffering of the buffer steel springs 14 and the support of the trapezoidal seat 15 above. In this way, when vibration occurs, in order to expand the amplitude of the vibration effect, through multiple buffer steel springs 14 and the hole position stage of the circular opening 25 in the middle of the top of the control box 21 above, multiple screening structures with the most appropriate and similar specifications are separated.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
