Description

Technical Field

[0001] The utility model relates to the technical field of red date screening, in particular to a material guiding device of a red date screening machine. Background Art

[0002] The same variety of red dates is generally graded based on size, color and breakage. Currently, red dates are usually graded using a red date screening machine, which is a device used to grade and screen red dates according to quality or size. When the red dates are transported on the conveyor belt, the camera collects image information of the red dates and uploads the collected image information to the AI ​​system. After analyzing the defects or size of the red dates based on the image information, the AI ​​system issues a command to send the red dates to the corresponding category of the discharge port, and pushes the red dates into the corresponding discharge channel through the material guiding device to achieve grading. However, the material guiding device commonly used in the prior art is a pulse airflow. Since the red dates are transported faster on the conveyor roller and the thrust of the pulse airflow is small, the red dates cannot be discharged smoothly. It is necessary to set up an additional reflux conveying device or manually send the red dates back to the screening machine for screening, which has the problems of low screening efficiency and cumbersome operation. At the same time, after the red dates are discharged from the discharge channel, a receiving box is usually placed at the discharge port for collection. However, when the receiving box is filled and the box is changed, the red dates are still being discharged, which will cause some of the red dates to be scattered on the ground, causing waste and low screening efficiency. Utility Model Content

[0003] The utility model aims to provide a material guiding device for a red date screening machine, which has the effect of solving the above-mentioned technical problems, facilitating material discharging and improving the red date screening efficiency.

[0004] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a material guiding device of a red date screening machine, comprising a plurality of conveying rollers, a bracket is provided on one side of the conveying rollers, a bottom plate is provided on the other side, a plurality of material guiding openings with a certain interval are opened on the bracket, the material guiding openings are provided with material guiding grooves, a pushing assembly opposite to the material guiding grooves is provided on the bottom plate, the pushing assembly comprises a support plate, a T-shaped connecting rod, and a fixed plate, a Y-shaped rotating part is rotatably connected to the top of the support plate, a driving motor is fixedly provided, the driving motor is used to drive the Y-shaped rotating part to rotate, two rocking arms are rotatably connected to the bottom plate, one end of the T-shaped connecting rod is hinged to the end of the Y-shaped rotating part away from the center, and the other end is hinged between the two rocking arms, one end of the fixed plate is fixed between the two rocking arms, and the other end is vertically fixedly connected to the pushing plate.

[0005] By adopting the above technical scheme, the red dates are conveyed out on the conveyor roller after being screened by the screening machine. When they move to the level to which their radius belongs, the screening machine computer controls the driving motor corresponding to the level to which the red dates belong to work, thereby driving the Y-shaped rotating part to rotate. When the Y-shaped rotating part rotates, it drives the T-shaped connecting rod to move forward and backward and the rocker to swing forward and backward around the bottom plate, thereby realizing the forward and backward movement of the fixed plate and the push plate. The push plate pushes the red dates forward to the relative material guide port, and the red dates slide out along the material guide trough to be collected. The material discharge is convenient and fast, and there is no need to set up an additional reflux conveying device. At the same time, because the fixed plate drives the push plate to retract upward after pushing the material, the red dates being conveyed on the conveyor roller will not be knocked off. It is easy to use and has the advantage of improving the screening efficiency of red dates.

[0006] The utility model is further configured as follows: a base is fixedly provided on the bottom plate, a fixing rod is fixedly provided in the base, a limiting member 1 and a limiting member 2 are fixedly provided at both ends of the fixing rod, and the rocker arm is sleeved on the fixing rod and rotatably connected between the limiting member 1 and the limiting member 2.

[0007] By adopting the above technical solution, the rocker is rotatably connected to the fixed rod, and the limiting member 1 and the limiting member 2 limit the two ends of the rocker, so that the rocker can only swing back and forth without deviation, thereby realizing a stable rotation connection between the rocker and the base plate.

[0008] The utility model is further configured as follows: a soft cushion is provided on the outer wall of the push plate.

[0009] By adopting the above technical solution, it is prevented that the push plate pushes the red dates and causes the surface of the red dates to be damaged, thereby reducing the quality of the red dates and causing waste.

[0010] The utility model is further configured as follows: right-angle plates are welded to both side walls of the support plate, one right-angle side of the right-angle plate is threadedly connected to the support plate, and the other right-angle side is threadedly connected to the bottom plate.

[0011] By adopting the above technical solution, two right-angle plates are provided to support the two side edges of the support plate, thereby preventing the support plate from tilting and making it more stable.

[0012] The utility model is further configured as follows: the three outer angles of the Y-shaped rotating part are equal.

[0013] By adopting the above technical solution, when the connection point between the Y-shaped rotating part and the T-shaped connecting rod moves from the highest point to the position closest to the conveying roller, it drives the push plate forward to push the material. When the connection point moves from the position closest to the conveying roller to the bottom, the push plate moves upward and backward to resume the next push of the material. The red dates being transported on the conveying roller will not be knocked off. The use is simple and convenient.

[0014] The utility model is further configured as follows: the material guide trough is arranged along the material guide opening and tilted downward.

[0015] By adopting the above technical solution, the red dates fall into the material guide trough through the material guide port and automatically fall out of the material guide trough.

[0016] The utility model is further configured as follows: a folding plate is hingedly connected to one end of the material guide trough away from the conveying roller, and the folding plate is connected to the material guide trough by bolts.

[0017] The utility model is further configured as follows: it also includes a material collecting frame, and the material collecting frame is used for collecting the red dates dropped from the material guiding trough.

[0018] By adopting the above technical solution, when the aggregate frame needs to be replaced, the folding plate and the material guide trough are sealed with bolts to stop the red dates from falling. At this time, the red dates are stored in the material guide trough. After the replacement is completed, the folding plate is opened downward to continue feeding. This can prevent the red dates from falling to the ground when the aggregate frame is replaced. There is no need to stop screening, which is more practical and can further improve the efficiency of red date screening.

[0019] The utility model is further configured as follows: a rotating shaft is fixedly arranged at the center of the Y-shaped rotating member, the rotating shaft is rotatably connected to the top of the supporting plate and is fixedly connected to the output end of the driving motor.

[0020] By adopting the above technical solution, the driving motor drives the rotating shaft to rotate, thereby driving the Y-shaped rotating member to rotate, thereby realizing the rotational connection between the Y-shaped rotating member and the support plate.

[0021] The utility model is further configured such that: when the push plate moves to the lowest point, the bottom of the push plate is connected to the top of the conveying roller.

[0022] By adopting the above technical solution, the red dates can be pushed to the material guide port to prevent the push plate from being pushed empty and causing the red dates to be missed and not collected, thereby improving the screening efficiency.

[0023] The beneficial effects of the utility model are as follows: a driving motor is arranged to drive the Y-shaped rotating part to rotate, and when the Y-shaped rotating part rotates, it drives the T-shaped connecting rod to move forward and backward, and the rocker arm to swing forward and backward around the bottom plate, thereby realizing the forward and backward movement of the fixed plate and the push plate, and the push plate pushes the red dates forward to the relative material guide port, and the red dates slide out along the material guide groove to be collected, and the material discharge is convenient and fast, and there is no need to additionally set up a reflux conveying device. At the same time, because the fixed plate drives the push plate to retract upward after pushing the material, the red dates being conveyed on the conveying roller will not be knocked off, and it is easy to use and has the advantage of improving the efficiency of red date screening.
