In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0034] The following is based on the attached Figure 1 To Attachment Figure 4 The utility model introduces a rake material transport device, which aims to solve the blockage problem caused by equipment failure or operation error in the traditional glass raw material transportation process, and improve the transportation efficiency and stability.
[0035] like Figure 1 , Figure 2 As shown, the rake material transport device of the utility model mainly includes a rake material machine 1, a lower hopper 2, a belt conveyor and a gate valve 6.
[0036] Among them, the rake material machine 1 is mainly composed of a walking mechanism and a rake material mechanism, and the walking mechanism and the rake material mechanism are driven by a walking motor and a rake material motor respectively. The walking motor is the power source for the rake material machine 1 to travel. It usually adopts a high-performance electric motor with sufficient torque and stable output power to ensure that the rake material machine 1 can move smoothly under different loads. The walking motor is connected to the walking wheel of the rake material machine 1 through a transmission mechanism, thereby driving the rake material machine 1 to move back and forth in the material pile to rake and transport the glass raw materials. The rake material motor is responsible for driving the rake material mechanism, which includes components such as rake teeth and chains, which are used to rake the glass raw materials out of the material pile and push them to the transportation device. The rake material motor needs to have a higher speed and power to cope with the larger resistance and weight of raw materials such as glass raw materials. By accurately controlling the speed and direction of the rake material motor, efficient and uniform raking of glass raw materials can be achieved.
[0037] The lower hopper 2 is located below the rake feeder 1, and its main function is to collect and limit the glass raw materials or other glass raw materials transported by the rake feeder 1. The lower hopper 2 is designed as an inverted cone or funnel-shaped structure, and its lower end has a discharge port 21. This shape is conducive to the smooth sliding of the raw materials due to their own gravity, reducing the risk of blockage during the material discharge process. Its inner wall is smooth to reduce the friction resistance of the raw materials during the sliding process, ensuring that the raw materials can enter the belt conveyor smoothly and quickly.
[0038] The belt conveyor receives the glass raw materials limited by the lower hopper 2 and transports them to the subsequent processing equipment. The gate valve 6 is arranged above the belt 5 of the belt conveyor, and its main function is to limit the efficiency of the belt conveyor in receiving the glass raw materials from the lower hopper 2. The gate valve 6 includes a through notch 611, and the area between the inner edge of the through notch 611 and the belt 5 is limited to a preset area to ensure that the glass raw materials pass through at a constant speed to prevent blockage caused by excessive output.
[0039] Specifically, the preset area can be calculated based on the rated output of the belt conveyor. For example, by substituting known parameters into the calculation formula: belt 5 linear speed v×preset area S×material density ρ×3600s=rated conveying volume kg / h, the preset area S can be quickly calculated to ensure that the actual output does not exceed the rated output of the belt conveyor, so as to achieve the best material conveying ratio between different equipment, give full play to the best transportation efficiency of various equipment, prevent the waste of energy and time caused by long-term low-volume transportation, and prevent material blockage caused by overload transportation.
[0040] Through the rake material transport device, the gate valve 6 can be used to limit the efficiency of the glass raw materials entering the belt conveyor from the lower hopper 2, so as to ensure that the glass raw materials fall from the lower hopper 2 to the belt 5 at a constant speed, thereby limiting the transportation efficiency of the entire conveying production line, avoiding the phenomenon of blockage failure of subsequent equipment, and ensuring the normal progress of the glass raw material transportation operation with guaranteed quality and quantity.
[0041] Specifically, Figure 2 , Figure 3 As shown, the gate valve 6 includes a limiting gate 61, and the limiting gate 61 is provided with a through notch 611, and the through notch 611 is provided at the lower end of the limiting gate 61. By adjusting the position of the limiting gate 61 and the size of the through notch 611, the passing amount of the glass raw material can be accurately controlled, thereby further improving the stability and efficiency of transportation.
[0042] Preferably, the distance between the inner edge of the notch 611 and the belt 5 gradually decreases along the direction from the central axis of the gate valve 6 to both ends. Exemplarily, the notch 611 is semicircular, semi-elliptical, semi-regular hexagonal, etc. This shape can "cut the peaks and fill the valleys" for unevenly distributed materials, so that they are piled flatly and evenly in the middle of the belt 5, which not only plays the role of "quantitative balance", but also prevents materials from spilling from the upper belt 5 to the lower belt 5, and finally being transported to the tail wheel of the belt conveyor for accumulation, causing the belt 5 to deviate or deform, thereby extending the service life of the belt 5 and greatly reducing the cleaning intensity of the operator.
[0043] In order to increase flexibility and adaptability, the distance between the limiting gate 61 and the belt 5 can be adjustable. Figure 3 , Figure 4 As shown, the gate valve 6 may further include a gate fixing member 62 and an adjusting screw 63. The gate fixing member 62 is fixedly mounted with a limiting gate 61, and the lower end of the adjusting screw 63 is fixedly connected to the gate fixing member 62. By rotating the adjusting screw 63, the distance between the limiting gate 61 and the belt 5 can be conveniently adjusted, thereby controlling the passing speed of the glass raw material.
[0044] Exemplarily, the rake material transport device further includes a fixed frame 7, and the adjusting screw 63 is vertically penetrated in the frame 7, so as to fix the gate valve 6 through the frame 7. At least two fixing nuts 64 are sleeved on the adjusting screw 63, and at least one fixing nut 64 is respectively provided on the upper and lower sides of the frame 7 to ensure the stability and adjustment accuracy of the gate valve 6.
[0045] When adjusting the height of the gate valve 6, the operator first needs to loosen the fixing nut 64 so that the adjusting screw 63 can move freely up and down in the frame 7. Then, by moving the adjusting screw 63 up and down, the distance between the limiting gate 61 and the belt 5 can be accurately adjusted. When the desired height is reached, the fixing nut 64 is tightened again to ensure that the gate valve 6 is fixed to the frame 7.
[0046] In order to facilitate the maintenance and replacement of the limiting gate 61, the gate fixing member 62 is provided with a threaded hole, and the limiting gate 61 is provided with a through hole. The gate valve 6 also includes a fixing bolt, which passes through the through hole and is threadedly connected to the threaded hole to fix the limiting gate 61 to the gate fixing member 62. This connection method is both firm and can be easily replaced after the limiting gate 61 is worn.
[0047] At the same time, if Figure 1 , Figure 2 As shown, in order to prevent the glass raw materials from scattering during transportation, baffle plates 4 can be provided on both sides of the belt 5. Along the transportation direction of the belt conveyor, one end of the baffle plate 4 abuts against the lower hopper 2, and the other end abuts against the gate valve 6. In this way, it can be ensured that the glass raw materials are always kept on the belt 5 during transportation, reducing scattering and waste. In addition, the baffle plate 4 can also play a certain role in preventing the gate valve 6 from rotating, thereby avoiding the failure of the gate valve 6 to limit the transportation efficiency.
[0048] Preferably, if Figure 1 As shown, a level switch 3 may be provided inside the lower hopper 2. The level switch 3 is used to sense the stacking height of the glass raw materials in the lower hopper 2, and the signal is connected to the rake machine 1. When the stacking height of the glass raw materials reaches a preset value, the level switch 3 may send a signal to the rake machine 1 to control the operating state of the rake machine 1. For example, when the glass raw materials are stacked too high, the operation of the rake machine 1 may be automatically stopped to prevent a blockage caused by excessive output.
[0049] Specifically, the level switch 3 can be electrically connected to the travel motor of the rake machine 1. When it is sensed that the stacking height of the glass raw materials reaches a preset value, the level switch 3 can send a stop signal to the travel motor to suspend the operation of the rake machine 1. This automatic control can greatly improve the stability and safety of transportation, and compared with controlling the operation of a rake motor with a larger feed, it can extend the working life of the rake machine 1 and reduce the failure rate caused by multiple starts and stops.
[0050] During operation, the rake feeder 1 is first driven by the travel motor and moves along a preset path on the material pile. When the rake feeder 1 moves to the material pile position, the rake feeder motor starts and drives the rake feeder 1 to start working. Driven by the rake feeder motor, the rake teeth penetrate into the material pile, rake out the glass raw materials and push them to the lower hopper 2. In this process, the travel motor and the rake feeder motor need to work together to ensure that the glass raw materials can be stably and continuously transported to the next link. When the level switch 3 senses that the accumulation height of the glass raw materials in the lower hopper 2 reaches the preset value, the travel motor will be stopped, so that the rake feeder 1 stays at a fixed position. After staying for a period of time, the glass raw materials at this position will be transported out, and the lower hopper 2 will be in a state of no glass raw material input and only glass raw material output, and the accumulation height of the glass raw materials will drop below the preset value. At this time, the level switch 3 stops sending signals, the travel motor is enabled again, and the rake feeder 1 is driven to move to the remaining positions where glass raw materials exist, so that the glass raw materials can continue to be input into the lower hopper 2.
[0051] Optionally, the level switch 3 selects a high-precision sensor such as a rotary resistance switch to ensure the accuracy and reliability of the induction. The rotary resistance switch includes a micro motor, a transmission shaft, blades, a torsion spring and a detection mechanism. When the rotary resistance switch does not contact the material, the micro motor operates normally, driving the transmission shaft and the blades to rotate. When the blade contacts the material, the micro motor stops rotating due to the resistance. At this time, the detector will output a power-on signal and the above-mentioned stop signal, and at the same time cut off the power supply to stop the micro motor. When the material drops or is removed, the resistance to the blade disappears, the detector will rely on the power of the torsion spring to restore to the original state, and the micro motor can be restarted.
[0052] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
