The upper eccentric block 310 and the lower eccentric block 320 are respectively mounted on two output shafts of the motor 300 in a first direction, and the upper eccentric block 310 is positioned at one side of the lower eccentric block 320 near the guide plate 120 in the first direction. The sensing mechanism connects the screen 110 and the upper eccentric block 310, and when a material falls onto the screen 110, the screen 110 is caused to move in a first direction, and movement of the screen 110 in the first direction causes the sensing mechanism to act, which can drive the upper eccentric block 310 to rotate about the first direction relative to the lower eccentric block 320, changing the phase angle of the upper and lower eccentric blocks 310, 320, and thus changing the rate of material diffusion on the screen 110, and causing the phase angle of the upper and lower eccentric blocks 310, 320 to be positively correlated with the weight of the material.

Specifically, a plurality of guide blocks 104 are disposed on the casing 100, the plurality of guide blocks 104 are uniformly distributed in the circumferential direction of the casing 100, a guide chamber is formed inside the guide blocks 104, the guide chamber is communicated with the casing 100, an inclined surface 105 is formed in the guide chamber, the inclined surface 105 is provided with a head end and a tail end, the head end is located at one side of the tail end away from the guide plate 120 along a first direction, the head end is located at one side of the tail end away from the central axis of the screen 111 along a second direction, two elastic sheets 117 adjacently disposed around the first direction are located in the same guide chamber, and in an initial state, the end parts of the elastic sheets 117 penetrate through the connecting ring 113 and are abutted against the head ends of the inclined surfaces 105 correspondingly disposed.
In this embodiment, by further arranging the partition 115 and the elastic sheet 117 to cooperate, when the material falls on the screen 111 and causes the screen 111 to move downward along the first direction, the whole screening member 110 is driven to move synchronously, because the end of the elastic sheet 117 abuts against the head end of the inclined plane 105 correspondingly arranged in the initial state, when the elastic sheet 117 continues to move downward along the first direction, the elastic sheet 117 is caused to move from the head end of the inclined plane 105 to the tail end of the inclined plane 105, and then the elastic sheet 117 is caused to deform, and the elastic sheet 117 is caused to move along the second direction to a position close to the central axis of the screen 111, after the elastic sheet 117 moves, under the subsequent vibration action, the moving space of the circular ring 116 in the screening area correspondingly arranged in the elastic sheet is increased, that is, the circular ring 116 drives the marble 114 arranged in the circular ring 116 to approach from the edge of the screen 111 to the middle. The larger the weight of the material on the screen 111 is, the larger the space for the circular ring 116 to move after the elastic sheet 117 deforms, namely the larger the action of the marble 114 in the circular ring 116 on the screen 111 corresponding to the position of the marble is, after the diffusion speed of the material is slowed down along with the increase of the weight of the material, the impact position of the marble 114 on the screen 111 is synchronously regulated, so that the screen 111 is prevented from being blocked.
By combining the above embodiments, the specific working principle and working process are as follows:
In use, the motor 300 is started, under the action of the upper eccentric block 310 and the lower eccentric block 320, the rotary motion of the motor 300 is converted into a horizontal, vertical and inclined multidirectional motion, so that the motion of the motor 300 is transmitted to the sieving member 110, and when the material falls on the sieving member 110, the rotation of the motor 300 drives the upper eccentric block 310 and the lower eccentric block 320 to synchronously rotate, and at the moment, the upper shafts of the upper eccentric block 310 and the motor 300 are kept relatively stationary.
When the material is fed into the housing 100 from the feed inlet 102, the material falls on the screen 111, and then the material performs an involute movement on the screening member 110 to screen the material.
When the material falls on the screen 111, the screen 111 will move downwards under the gravity action of the material, and drive the whole screening member 110 to move synchronously, and drive the driving rod 400 to move synchronously, because the driving rod 400 is abutted with the upper eccentric block 310, the driving rod 400 will further drive the upper eccentric block 310 to move along the first direction, and rotate the upper eccentric block 310 around the first direction relative to the upper shaft and the lower eccentric block 320, so as to change the phase angle between the upper eccentric block 310 and the lower eccentric block 320, and the movement of the upper eccentric block 310 along the first direction will compress the first elastic member, and the phase angle between the upper eccentric block 310 and the lower eccentric block 320 can be positively correlated with the weight of the material by further setting the spiral transmission direction of the upper eccentric block 310 and the upper shaft. That is, the heavier the material, the larger the phase angles of the upper eccentric block 310 and the lower eccentric block 320, the slower the material diffusion speed, the lighter the material, the smaller the phase angles of the upper eccentric block 310 and the lower eccentric block 320, the faster the diffusion speed, thereby realizing the adjustment of the material diffusion speed on the sieving member 110 according to the weight of the material, avoiding the accumulation of the edges of the sieving member 110 due to the large weight of the material and the too fast diffusion speed, and improving the utilization rate of the sieving member 110 at the central position, accelerating the sieving and improving the working efficiency due to the relatively slow diffusion speed when the material is large.
And in the screening process, along with the gradual screening of the materials on the screening piece 110, the weight of the materials on the screening piece 110 is changed, so that the first elastic piece is driven to reset upwards, the driving rod 400 and the screening piece 110 are driven to move upwards for resetting, and the real-time adjustment between the phase angles of the upper eccentric block 310 and the lower eccentric block 320 and the weight of the materials is realized, so that the overall screening efficiency is improved.
Meanwhile, because the end of the elastic sheet 117 abuts against the head end of the inclined plane 105 correspondingly arranged in the initial state, when the elastic sheet 117 continuously moves downwards along the first direction, the elastic sheet 117 is promoted to move from the head end of the inclined plane 105 to the tail end of the inclined plane 105, and then the elastic sheet 117 is promoted to deform, so that the elastic sheet 117 moves towards the position close to the central axis of the screen 111 along the second direction, and after the elastic sheet 117 moves, under the action of subsequent vibration, the moving space of the circular ring 116 in the screening area correspondingly arranged is increased, namely, the circular ring 116 drives the marbles 114 arranged in the circular ring to approach from the edge of the screen 111 to the middle. The larger the weight of the material on the screen 111 is, the larger the space for the circular ring 116 to move after the elastic sheet 117 deforms, namely the larger the action of the marble 114 in the circular ring 116 on the screen 111 corresponding to the position of the marble is, after the diffusion speed of the material is slowed down along with the increase of the weight of the material, the impact position of the marble 114 on the screen 111 is synchronously regulated, so that the screen 111 is prevented from being blocked. After the materials in the first chamber 130 and the second chamber 140 are respectively discharged from the discharge ports 103 correspondingly arranged, the screening of the materials is completed.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
