[0002] In the process of handling garbage, it is usually necessary to use a spreader to break up and evenly distribute garbage of different sizes. During the operation of the spreader, due to the different sizes and disorder of the garbage, the discharge volume of the hopper is sometimes large and sometimes small. When the total weight of the garbage that needs to be broken up by the spreader's turntable at a certain moment is too large, the speed of the turntable may decrease too much or even stop, resulting in the inability to effectively break up the garbage. Summary of the Invention

[0028] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0029] Reference Figure 1 、 Figure 2 and Figure 4 According to an embodiment of the present invention, a bulk material dispensing device includes a frame 100, a bulk material dispensing mechanism, a weighing sensor, and a control device. The frame 100 is equipped with a hopper 200; the bulk material dispensing mechanism includes a mounting beam 310, a turntable 320, and a driving device 330. The mounting beam 310 is mounted on the frame 100, and the turntable 320 is rotatably mounted on the mounting beam 310. The turntable 320 is located below the discharge port of the hopper 200. The driving device 330 is mounted on the mounting beam 310 and can drive the turntable 320 to rotate. The weighing sensor is arranged between the mounting beam 310 and the frame 100, and is used to measure the impact force on the turntable 320. The control device is electrically connected to the weighing sensor and the driving device 330, and the control device can adjust the output power of the driving device 330 according to the measurement data of the weighing sensor.

[0030] During the working process of the bulk material dispensing device, the material discharged from the discharge port of the hopper 200 falls onto the rotating turntable 320, and then the turntable 320 scatters the material. In this process, the greater the discharge amount of the hopper 200, the greater the impact force of the material on the turntable 320, and the greater the reduction in the rotation speed of the turntable 320. The bulk material dispensing device provided by the present invention can measure the impact force exerted on the turntable 320 by a weighing sensor, and can timely obtain the change in the discharge amount of the hopper 200. Then, the control device can adjust the output power of the driving device 330 according to the measurement data of the weighing sensor, and the discharge of the hopper 200 is controlled. The larger the amount, the greater the impact force on the turntable 320, and the greater the output power of the drive device 330, so that the rotation speed of the turntable 320 remains stable or even increases. In this way, when the discharge amount of the hopper 200 is large, the rotation speed of the turntable 320 can be avoided from being reduced too much or even stopped, thereby ensuring that the turntable 320 can work normally and ensure that the turntable 320 can effectively break up the material; in addition, the impact force on the turntable 320 is measured by a weighing sensor, and then the change in the discharge amount of the hopper 200 is obtained. This measurement method has a simple and convenient measurement process and is easy to implement.

[0031] In the specific implementation process, the measurement accuracy of the above-mentioned weighing sensor may not be high, but its measuring range needs to be large. Therefore, a weighing sensor with a large measuring range such as a magnetic pole variable weighing sensor or a bellows weighing sensor 400 can be selected.

[0032] Reference Figure 2 and Figure 4 It is conceivable that in some embodiments, the end of the mounting beam 310 away from the turntable 320 is movably connected to the frame 100, and the weighing sensor is configured as a bellows weighing sensor 400. One end of the bellows weighing sensor 400 is connected to the frame 100, and the other end is connected to the mounting beam 310 or supported on the lower side of the mounting beam 310. In this way, the bellows weighing sensor 400 can support the mounting beam 310, and the impact force on the turntable 320 can be applied to the bellows weighing sensor 400 through the mounting beam 310, and the bellows weighing sensor 400 can then measure the impact force. In addition, through the above arrangement, the mounting beam 310 is mainly supported by the bellows weighing sensor 400. In this way, the bellows weighing sensor 400 can be used to buffer the bulk material mechanism, thereby reducing damage to the turntable 320 caused by material impact and increasing the service life of the turntable 320.

[0033] In addition, since the end of the mounting beam 310 away from the turntable 320 is movably connected to the frame 100, when the bellows weighing sensor 400 is supported on the lower side of the mounting beam 310, the inclination angle of the mounting beam 310 can be adjusted during the assembly process, thereby adjusting the inclination angle of the upper end surface of the turntable 320.

[0034] Reference Figure 2 and Figure 4 It is conceivable that in some embodiments, the bellows load cell 400 is located on the lower side of the mounting beam 310, and a support base 350 is provided between the bellows load cell 400 and the mounting beam 310. The upper end surface of the support base 350 is in contact with the lower side surface of the mounting beam 310, and the lower end surface of the support base 350 is detachably connected to the bellows load cell 400. The inclination angle of the upper end surface of the support base 350 is consistent with the inclination angle of the mounting beam 310, so that the upper end surface of the support base 350 is in contact with the lower side surface of the mounting beam 310, while the lower end surface of the support base 350 can always maintain good contact with the bellows load cell 400. In this way, the bellows load cell 400 can make more accurate measurements. During the assembly process, the inclination angle of the mounting beam 310 is adjusted, and the support seat 350 with a corresponding inclination angle of the upper end face can be replaced to ensure that the upper end face of the support seat 350 is in contact with the lower side face of the mounting beam 310. This process does not require adjusting the installation position of the bellows weighing sensor 400, and can also ensure that the lower end face of the support seat 350 is in good contact with the bellows weighing sensor 400. The adjustment process is convenient and simple.

[0035] Reference Figure 2 and Figure 5 It is conceivable that in some embodiments, the end of the mounting beam 310 away from the turntable 320 is hinged with a connecting rod 360, and the connecting rod 360 is hinged to the frame 100. In this way, the end of the mounting beam 310 away from the turntable 320 is movable, and the structure is simple and easy to assemble.

[0036] Of course, in the specific implementation process, other settings can also be used to make the end of the mounting beam 310 away from the turntable 320 movable. For example, an arc guide rail can be set on the frame 100, and a slider is installed on the end of the mounting beam 310 away from the turntable 320. The slider is slidably set on the guide rail. In this way, the end of the mounting beam 310 away from the turntable 320 can move along the guide rail.

[0037] Reference Figure 1 and Figure 3 It is conceivable that in some embodiments, two bulking mechanisms are provided, one of which is located on either side of the other, and two load cells are provided, one correspondingly disposed between the two mounting beams 310 and the frame 100. Thus, by providing two bulking mechanisms, the bulker can process more material simultaneously, thereby increasing its load capacity. Furthermore, the two turntables 320 can disperse the material more evenly. It is also conceivable that, in specific implementations, more bulking mechanisms may be provided as needed.

[0038] When the height positions of the two turntables 320 are the same, the materials thrown out by the two turntables 320 are likely to directly impact the turntable 320, and the two turntables 320 are likely to interfere with each other. Figure 1 and Figure 3 It is conceivable that in some embodiments, the two turntables 320 are positioned at different heights, wherein the material thrown out by the turntable 320 at a higher height will not directly hit the other turntable 320, and the mutual interference between the two turntables 320 is small, thereby reducing the impact on the turntable 320.

[0039] Reference Figure 1 、 Figure 2 and Figure 5 It is conceivable that in some embodiments, the frame 100 includes a first mounting plate 110 and a second mounting plate 120. The second mounting plate 120 is connected to the first mounting plate 110 and is arranged at an angle to the first mounting plate 110. The second mounting plate 120 and the first mounting plate 110 enclose a bulking area 130. The first mounting plate 110 defines a clearance opening 111. The hopper 200 is mounted on the first mounting plate 110, and the discharge port of the hopper 200 is connected to the clearance opening 111. The mounting beam 310 is mounted on the second mounting plate 120, and the turntable 320 is located in the bulking area 130. Through the above arrangement, the structure of the frame 100 is relatively simple and easy to manufacture. The bulking device can also be integrally installed in a waste disposal system, facilitating its application.

[0040] Reference Figure 1 、 Figure 2 and Figure 5 It is conceivable that in some embodiments, the second mounting plate 120 is arranged at an acute angle to the first mounting plate 110. The second mounting plate 120 defines a third avoidance hole 121, through which the mounting beam 310 passes. The drive device 330 is mounted on the end of the mounting beam 310 facing away from the bulk material area 130, and the load cell is positioned on the side of the second mounting plate 120 facing away from the discrete material area 130. In this manner, the drive device 330 and the load cell can be positioned away from the material, effectively preventing material from coming into contact with them, thereby improving the reliability of the bulk material feeder and reducing the risk of malfunctions. Furthermore, the mounting beam 310 can be fitted with a shielding member 500, which abuts the side of the second mounting plate 120 facing away from the bulk material area 130 and covers the third avoidance hole 121. This effectively prevents material from passing through the third avoidance hole 121 and then coming into contact with the drive device 330.

[0041] Reference Figure 1 、 Figure 2 and Figure 5It is conceivable that, in some embodiments, a mounting seat 122 is provided on one side of the second mounting plate 120 behind the discrete material area 130, and the weighing sensor is configured as a bellows weighing sensor 400, one end of the bellows weighing sensor 400 is connected to the mounting seat 122, and the other end is connected to the mounting beam 310.

[0042] Reference Figure 6 It is conceivable that in some embodiments, a mounting cavity 311 is provided within the mounting beam 310, and a first avoidance hole and a second avoidance hole are provided on the mounting beam 310 that communicate with the mounting cavity 311. A transmission belt 340 is provided within the mounting cavity 311. The drive device 330 includes a motor, which is mounted on the outer wall of the mounting beam 310, and the output shaft of the motor passes through the first avoidance hole. The transmission belt 340 is located within the mounting cavity 311 and is transmission-connected to the output shaft of the motor. A rotating shaft 321 is connected to the lower end of the turntable 320, and the rotating shaft 321 passes through the second avoidance hole and is transmission-connected to the transmission belt 340. Through this arrangement, the drive device 330 and the transmission belt 340 can avoid material, effectively preventing material from contacting the drive device 330 and the transmission belt 340, thereby ensuring the reliability of the bulk material collector.

[0043] Of course, in the specific implementation process, the above-mentioned transmission belt 340 can be replaced by a transmission shaft, which is connected to the rotating shaft 321 of the turntable 320 and the rotating shaft 321 of the motor through a turbine-worm structure, and the transmission shaft is arranged in the above-mentioned installation cavity 311.

[0044] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The embodiment is described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiment. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the present invention.
