[0039] In the description of the present application, the meaning of "a plurality of" is two or more.

[0040] The feeding mechanism 1 according to the embodiments of the present application is described below with reference to the accompanying drawings.

[0041] As shown in Figures 1-2 The feeding mechanism 1 according to the embodiments of the present application includes a material box 100, a switch piece 200 driving motor 300 and a protective cover 600.

[0042] The material box 100 is provided with a storage space 110 and a material taking and placing opening 120, the storage space 110 and the material taking and placing opening 120 are communicated, the switch piece 200 is connected with the material box 100 and is movable between an open position and a closed position, when the switch piece 200 is in the open position, the storage space 110 is communicated with the atmosphere through the material taking and placing opening 120, when the switch piece 200 is in the closed position, the communication between the storage space 110 and the atmosphere is blocked. The driving motor 300 is connected with the material box 100 and located below the material box 100, the driving motor 300 is used to drive the material box 100 to move in the up-down direction. A part of the protective cover 600 is located between the material box 100 and the driving motor 300.

[0043] For example, the working process of the feeding mechanism 1 is as follows:

[0044] When the driving motor 300 drives the material box 100 to move downwards, the switch piece 200 is in the open position, and the material to be transported is placed into the storage space 110 through the material taking and placing opening 120; when the driving motor 300 drives the material box 100 to move upwards, the switch piece 200 is in the closed position, and the switch piece 200 prevents the material in the storage space 110 from falling; when the driving motor 300 drives the material box 100 to move upwards, the switch piece 200 is in the open position, and the material in the storage space 110 is taken out from the material taking and placing opening 120; when the driving motor 300 drives the material box 100 to move downwards, the switch piece 200 can be in either the open position or the closed position, and preferably in the closed position to prevent the residual material in the storage space 110 from falling.

[0045] The switch piece 200 can be a plug valve.

[0046] When the switch piece 200 is blocked by the material in the storage space 110, the switch piece 200 can not be moved to the closed position, and thus the material in the storage space 110 can fall when the material box 100 moves upwards. By arranging the protective cover 600 and locating a part of the protective cover 600 between the material box 100 and the driving motor 300, the falling material can be prevented from contacting the driving motor 300, the driving motor 300 can be prevented from being blocked by the material, and thus the driving motor 300 can be prevented from being burned due to excessive load, and the probability of damage of the driving motor 300 can be reduced.

[0047] Thus, the feeding mechanism 1 of the embodiment of the present application can prevent the material in the material box 100 from falling onto the driving motor 300 by additionally arranging the protective cover 600, and the probability of damage of the driving motor 300 can be reduced.

[0048] In some specific embodiments of the present application, as shown in Figure 3 and Figure 4 the protective cover 600 covers at least the peripheral surface and the top surface of the driving motor 300, and the protective cover 600 can also cover the bottom surface of the driving motor 300. In this way, the driving motor 300 is covered by a larger area, the falling of the material in the material box 100 onto the driving motor 300 can be more effectively avoided, and the probability of collision of the driving motor 300 can also be reduced, and the service life of the driving motor 300 can be improved.

[0049] For example, the motor shaft of the driving motor 300 can extend out of the protective cover 600 and be drivingly connected with the material box 100, or the motor shaft of the driving motor 300 is connected with a transmission structure 700, and the transmission structure 700 extends out of the protective cover 600 and is drivingly connected with the material box 100 to drive the material box 100.

[0050] In some specific embodiments of the present application, as shown in Figure 3As shown, the feeding mechanism 1 further comprises a light-transmitting piece 620, which can be made of light-transmitting material, such as light-transmitting glass or light-transmitting plastic. The light-transmitting piece 620 is connected with the protective cover 600, and the protective cover 600 is provided with an observation hole 610, and the light-transmitting piece 620 covers the observation hole 610.

[0051] In this way, the operator can observe the driving motor 300 through the light-transmitting piece 620, which is convenient for observing the running condition of the driving motor 300 and avoids the accumulation of materials from the observation hole 610 into the protective cover 600 to cause the driving motor 300 to be blocked, thereby reducing the probability of the driving motor 300 being burned out.

[0052] Specifically, the observation hole 610 can be a hole with a size of 100mm*10mm, and the driving motor 300 is usually installed at a low position. The observation hole 610 can be arranged on the upper surface of the protective cover 600, so that the operator can observe the driving motor 300 without having to squat or excessively bend over, thereby improving the comfort of use.

[0053] In some specific embodiments of the present application, as shown in Figure 4 As shown, the feeding mechanism 1 further comprises a cover plate 630, which is connected with the protective cover 600 and can rotate between a covering position and an observation position. The protective cover 600 is provided with an observation hole 610, and the cover plate 630 covers the observation hole 610 when the cover plate 630 is in the covering position. When the cover plate 630 is in the observation position, the observation hole 610 is open, and the operator can observe the driving motor 300 through the observation hole 610.

[0054] In this way, the operator can observe the driving motor 300 through the light-transmitting piece 620, which is convenient for observing the running condition of the driving motor 300 and avoids the accumulation of materials from the observation hole 610 into the protective cover 600 to cause the driving motor 300 to be blocked, thereby reducing the probability of the driving motor 300 being burned out.

[0055] Specifically, the observation hole 610 can be a hole with a size of 100mm*10mm, and the driving motor 300 is usually installed at a low position. The observation hole 610 can be arranged on the upper surface of the protective cover 600, so that the operator can observe the driving motor 300 without having to squat or excessively bend over, thereby improving the comfort of use.

[0056] In some specific embodiments of the present application, as shown in Figure 9 and Figure 10 As shown, the feeding mechanism 1 further comprises a controller 400, which is electrically connected with the switch piece 200 and the driving motor 300, and the controller 400 controls the switch piece 200 to move between the open position and the closed position. In this way, the automation level of the feeding mechanism 1 can be improved, manual operation is not required, cost is saved, and safety is also improved accordingly.

[0057] For example, the feeding mechanism 1 can further include a control panel 410 or a control button 420 connected with the controller 400, through which the switching piece 200 can be switched between the open position and the closed position, meeting the demand of manual operation to cope with different use scenarios.

[0058] In some embodiments of the present application, as shown in Figure 9 and Figure 10 The feeding mechanism 1 further includes a first sensor 500. The first sensor 500 is electrically connected with the controller 400, and is used to detect the position of the material box 100. The controller 400 controls the movement of the switching piece 200 between the open position and the closed position according to the feedback result of the first sensor 500. The first sensor 500 can be a distance sensor, such as a sound wave distance sensor or a laser distance sensor. The communication between the first sensor 500 and the controller 400 can be wireless, such as radio communication, or the first sensor 500 and the controller 400 can be connected by wires for communication.

[0059] For example, when the first sensor 500 detects that the material box 100 moves upward, the controller 400 controls the switching piece 200 to be in the closed position; when the first sensor 500 detects that the material box 100 moves downward, the controller 400 controls the switching piece 200 to be in the open position or the closed position, preferably, when the first sensor 500 detects that the material box 100 moves downward, the controller 400 controls the switching piece 200 to be in the closed position, so as to prevent the remaining material in the material box 100 and reduce the risk of material falling; when the material box 100 moves to the lowermost position, the controller 400 controls the switching piece 200 to be in the open position, so as to facilitate the replenishment of material into the storage space 110 through the material taking and placing opening 120.

[0060] By setting the first sensor 500, the position of the switching piece 200 is linked with the position of the material box 100, which improves the intelligence and reduces the risk of material falling from the storage space 110, and the replenishment of material is also more convenient.

[0061] In some embodiments of the present application, as shown in Figure 9 and Figure 10 The feeding mechanism 1 further includes a second sensor 510 and an alarm device 520. The second sensor 510 is electrically connected with the controller 400, and is used to detect the position of the switching piece 200. The alarm device 520 is electrically connected with the controller 400, and the controller 400 controls whether the alarm device 520 alarms according to the feedback result of the alarm device 520.

[0062] For example, when the controller 400 controls the switching element 200 to switch to the closed position, if the second sensor 520 detects that the switching element 200 is not in the closed position, it indicates that the switching element 200 may be damaged or the switching element 200 is blocked by materials, causing the switching element 200 to fail to move normally, or when the controller 400 controls the switching element 200 to switch to the open position, if the second sensor 520 detects that the switching element 200 is not in the open position, it indicates that the switching element 200 may be damaged or the switching element 200 is blocked by materials, causing the switching element 200 to fail to move normally.

[0063] By setting the second sensor 520, the controller 400 can obtain the current position state of the switching element 200 in time. If the switching element 200 is working normally, the controller 400 controls the alarm device 520 not to issue an alarm, and if the switching element 200 is not working normally, the controller 400 controls the alarm device 520 to issue an alarm to prompt the operator that the switching element 200 is in an abnormal state, and the operator can maintain the switching element 200 in time.

[0064] The second sensor 510 can be a distance sensor, a pressure sensor, etc., such as a sound wave distance sensor or a laser distance sensor, and the alarm device 520 can include a buzzer, a loudspeaker, a sound box, an indicator light, a display screen, etc. The alarm device 520 prompts the operator by issuing sound, light, or display screen prompts.

[0065] In addition, the controller 400 and the second sensor 510 can be in wireless communication, such as radio communication, or the controller 400 and the second sensor 510 can be connected by wires for communication. The controller 400 and the alarm device 520 can be in wireless communication, such as radio communication, or the controller 400 and the alarm device 520 can be connected by wires for communication.

[0066] In some embodiments of the present application, as shown in Figure 5 The protective cover 600 includes a base 601, a support rod 602, and a protective plate 603. The bottom end of the support rod 602 is connected to the base 601, and the protective plate 603 is connected to the top end of the support rod 602. The protective plate 603 is located between the driving motor 300 and the material box 100.

[0067] By setting the protective plate 603, the materials in the material box 100 can be prevented from directly falling onto the driving motor 300, thereby preventing the driving motor 300 from being blocked, and avoiding the burning of the driving motor 300 due to the failure of the driving motor 300 to rotate;

[0068] By setting the support rod 602, the support plate 603 can be supported, and the support rod 602 can be stably positioned between the driving motor 300 and the hopper 100, and the volume of the support structure can be reduced, the cost and weight can be reduced, and the moving and transporting of the protective cover 600 can be facilitated.

[0069] By setting the base 601, and the cross-sectional area of the base 601 is greater than the cross-sectional area of the protective plate 603, the placement of the protective cover 600 can be stable, and the protective cover 600 can be prevented from shaking randomly.

[0070] For example, the driving motor 300 is connected with the protective plate 603, so that the positioning between the driving motor 300 and the protective plate 603 is more accurate, and the protective plate 603 can be prevented from shielding the driving motor 300. Alternatively, the driving motor 300 is installed on the base 601, the cross-sectional area of the base 601 is larger, and the installation between the driving motor 300 and the base 601 is more convenient.

[0071] Further, as shown in Figures 6-8 The upper surface of the protective plate 603 is provided with a storage groove 604, wherein the cross-sectional area of the storage groove 604 from top to bottom can be the same, or the cross-sectional area of the storage groove 604 from top to bottom can gradually decrease, and the storage groove 604 is conical or circular truncated conical. The material of the feeding mechanism 1 can fall into the storage groove 604, so as to prevent the material from scattering everywhere, and the material in the storage groove 604 is convenient for recycling, so as to realize reuse.

[0072] In addition, as shown in Figure 5 The support rod 602 is a plurality of support rods 602, and the plurality of support rods 602 are arranged along the circumference of the driving motor 300, wherein the driving motor 300 can be installed into the protective cover 600 through the gap between adjacent support rods 602.

[0073] In this way, the base 601 and the protective plate 603 are connected and fixed by the plurality of support rods 602, which can improve the reliability of the relative position between the base 601 and the protective plate 603, and the plurality of support rods 602 can provide greater support to the protective plate 603, so that the protective plate 603 can be used to install a driving motor 300 with greater weight, and the range of options for the driving motor 300 is wider.

[0074] In addition, since the plurality of support rods 602 shield a larger area of the outer circumferential surface of the driving motor 300, the material in the feeding mechanism 1 can be more effectively prevented from contacting the driving motor 300 in the radial direction of the driving motor 300, and the protective effect on the driving motor 300 is improved.

[0075] The other configurations and operations of the feeding mechanism 1 according to the embodiments of the present application are known to those skilled in the art, and will not be described in detail here.
