[0035] A connecting seat 210 is provided between the connecting rod 207 and the storage hopper 201, and the connecting rod 207 and the connecting seat 210 are movably connected.

[0036] In the preferred embodiment, the storage hopper 201 is provided with multiple extension rods 202 inside, the extension rods 202 are arranged perpendicularly to the inner wall of the storage hopper 201, and the outer circle of the extension rods 202 is provided with multiple material distribution rods 208, which are used to break up powder blocks when the storage hopper 201 vibrates.

[0037] In the preferred embodiment, limiting plates 209 are provided on both sides below the storage hopper 201. The limiting plates 209 are used to prevent the storage hopper 201 from moving laterally.

[0038] The bottom of the storage hopper 201 is provided with a primary sieve plate 212, and the primary sieve plate 211 is provided with multiple primary sieve holes 212. The primary sieve holes 212 are large enough for coarse and fine powder to pass through, but large powder blocks cannot pass through.

[0039] In a preferred embodiment, the conveying assembly 3 includes a coarse material conveying line 301 and a fine material conveying line 302. The coarse material conveying line 301 is used to convey coarse powder, and the fine material conveying line 302 is used to convey fine powder. The conveying directions of the coarse material conveying line 301 and the fine material conveying line 302 are opposite.

[0040] In the preferred embodiment, the second screening component 4 includes a coarse material guide plate 401, which is inclined downward. A fine material hopper 403 is also provided below the coarse material guide plate 401. A fine material guide plate 405 is provided inside the fine material hopper 403. The inclination direction of the fine material guide plate 405 is opposite to that of the coarse material guide plate 401.

[0041] The bottom end of the coarse material guide plate 401 is provided with a material hopper 402, and the coarse material conveying line 301 is provided below the material hopper 402. The fine material conveying line 302 is provided below the fine material guide plate 405.

[0042] In the preferred embodiment, the upper end plate of the coarse material guide plate 401 is provided with multiple through fine material holes 404. The fine material holes 404 are only large enough for fine powder to pass through, and the coarse material rolls along the coarse material guide plate 401 onto the coarse material conveying line 301.

[0043] The detailed working process of a konjac flour primary screening device is as follows: The konjac flour raw material to be screened is poured into the storage hopper 201 of the primary screening component 2. The storage hopper 201 is placed on the roller 103 in the roller groove 104 at the top of the screening support 101, and there is a certain amount of movement space on the roller 103 to facilitate subsequent vibratory screening.

[0044] The motor 203 is started. The motor 203 is mounted on the vibration bracket 102. The operation of the motor 203 drives the transmission wheel 205 to rotate between the transmission brackets 204. The rotation of the transmission wheel 205 causes the swing frame 206 on one side to swing, and the connecting rod 207 at one end of the swing frame 206 moves accordingly. The connecting rod 207 is movably connected to the storage hopper 201 through the connecting seat 210, thereby causing the storage hopper 201 to vibrate.

[0045] When the storage hopper 201 vibrates, the distribution rods 208 on the extended support rods 202 arranged vertically to the inner wall move accordingly, breaking up the powder lumps in the konjac flour raw material and preventing them from clogging the sieve holes. Under the action of vibration, the konjac flour moves towards the primary sieve plate 211 at the bottom of the storage hopper 201. The primary sieve holes 212 on the primary sieve plate 211 allow coarse and fine powder to pass through, while large powder lumps remain on the primary sieve plate 211. The limiting plates 209 on both sides below the storage hopper 201 ensure that the storage hopper 201 does not shift laterally during vibration, ensuring the stability of the screening.

[0046] The mixture of coarse and fine powder falling through the primary sieve hole 212 reaches the coarse material guide plate 401 of the secondary sieve assembly 4. The coarse material guide plate 401 is inclined downwards, and the fine material hole 404 on its upper end surface is only large enough for fine powder to pass through. The fine powder falls through the fine material hole 404 into the fine material hopper 403 below, and slides down the fine material guide plate 405 inside the fine material hopper 403 onto the fine material conveyor line 302. The coarse material rolls down the coarse material guide plate 401 to the bottom collection hopper 402, and then falls from the collection hopper 402 onto the coarse material conveyor line 301 below.

[0047] The coarse material conveying line 301 of the conveying component 3 transports coarse powder to a designated location for subsequent processing, such as further grinding, while the fine material conveying line 302 transports fine powder to the corresponding location, which can be used as qualified products after preliminary screening to enter the next processing stage. Moreover, the conveying directions of the coarse material conveying line 301 and the fine material conveying line 302 are opposite, which makes it easier to distinguish and collect konjac powder of different particle sizes.

[0048] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
