[0036] In order to solve the problems existing in the background art, the present application proposes the following technical scheme: a material taking device for chain bucket unloader, comprising a chain type material taking unit 1 in the chain bucket unloader and a material taking hopper 2 arranged in the chain type material taking unit 1, the chain type material taking unit 1 is the prior art, which is a material taking technology equipped in the chain bucket unloader, and related technologies can be searched in the Internet and existing patents, and the present application only improves the material taking hopper 2 in the chain type material taking unit 1.

[0037] Embodiment one

[0038] Reference Figures 1-4

[0039] The technical scheme of the technology is as follows

[0040] A baffle 6 is rotatably installed at the inner bottom end of the material taking hopper 2. In order to increase the anti-skid function, a plurality of anti-skid particles are arranged outside the baffle 6. The baffle 6 is a cuboid structure. Specifically, the baffle 6 is fixedly connected with a rotating rod 5 at both ends, and the rotating rod 5 is rotatably installed in the material taking hopper 2. Through the rotation of the baffle 6, the purpose is to block the bottom end of the feeding port of the material taking hopper 2, so as to avoid the material from falling and increase the material taking effect.

[0041] Further explanation, in order to form a closed area, so in the hopper 2 fixed with the partition 28, the partition 28 is cuboid structure, and the partition 28 is provided with a notch 13, the notch 13 is rectangular structure, and the notch 13 is rotatably mounted with a shaft 14, the outer fixed installation of the shaft 14 is provided with a tongue 4, the tongue 4 can be circular, rectangular or triangular and polygonal structure, and the setting of the tongue 4, the purpose is, when the hopper 2 with chain type material taking unit 1 for taking material, when a large amount of material into the hopper 2, so the material will be pressed on the tongue 4, thereby driving the tongue 4 downward movement, and at this time, the tongue 4 will drive the shaft 14 rotation, realize linkage.

[0042] In order to realize the movement of the tongue 4, realize the synchronous rotation of the baffle 6, form a file, so set up the linkage unit, and the linkage unit is arranged in the hopper 2, the specific linkage unit is used for driving the baffle 6 to rotate towards the hopper 2 when the hopper 2 is pressed.

[0043] The specific linkage unit is designed as follows:

[0044] The linkage unit comprises a first gear 7, a second gear 8 and a third gear 9 rotatably mounted on the outer portion of the hopper 2.

[0045] Similarly, the outer portion of the first gear 7, the second gear 8 and the third gear 9 is sleeved with the shell 3, which is used for protecting the first gear 7, the second gear 8 and the third gear 9, and the first gear 7, the second gear 8 and the third gear 9 are engaged with each other, so that the first gear 7 is coaxially fixedly connected with the shaft 14, the third gear 9 is coaxially fixedly connected with the rotating rod 5, and the connecting plate 15 is fixedly connected with the shaft 14 on the outer portion of the shaft 14. The connecting plate 15 is used for connecting the supporting spring 16, and the spring 16 is fixedly connected between the connecting plate 15 and the inner wall of the hopper 2. The spring 16 plays a reset role. When the chain type material taking unit 1 moves, the hopper 2 falls after the material, and the tongue 4 can be reset upward under the elastic force of the spring 16.

[0046] Among them, the diameter of the first gear 7, the second gear 8 and the third gear 9 gradually decreases, which is convenient for rotation transmission between each other.

[0047] The specific operation process is as follows:

[0048] When the chain type material taking unit 1 drives the material taking hopper 2 to take materials, the material taking hopper 2 is in contact with the materials, and the materials are scooped into the material taking hopper 2 under the driving of the chain type material taking unit 1, and the material taking hopper 2 takes more materials under the driving of the chain type material taking unit 1, and the materials in the material taking hopper 2 press the tongue 4, the tongue 4 rotates downward, the rotating shaft 14 rotates, the connecting plate 15 stretches the spring 16, at this time, the rotating shaft 14 drives the first gear 7 to rotate counterclockwise, and the first gear 7 drives the second gear 8 to rotate clockwise, the second gear 8 drives the third gear 9 to rotate counterclockwise. Figure 3 The third gear 9 drives the baffle 6 to rotate upward, so that the bottom end of the feeding port of the material taking hopper 2 is blocked, and the materials are prevented from sliding.

[0049] The third gear 9 drives the baffle 6 to rotate upward, so that the bottom end of the feeding port of the material taking hopper 2 is blocked, and the materials are prevented from sliding.

[0050] At this time, under the driving of the chain type material taking unit 1, the material taking hopper 2 is lifted and prepares to discharge, if the material taking hopper 2 discharges, the tongue 4 rotates upward under the elastic pulling of the spring 16, the baffle 6 rotates and opens through the driving of the first gear 7, the second gear 8 and the third gear 9, and welcomes the next material taking.

[0051] In summary, when the material taking hopper 2 in the chain type material taking unit 1 takes materials, the bottom end of the feeding port of the material taking hopper 2 is blocked in time through the rotation of the baffle 6 when the material taking hopper 2 is lifted, and the materials are prevented from sliding.

[0052] Embodiment two

[0053] The embodiment is different from the embodiment one in that,

[0054] Reference Figure 1 、 Figure 6 and Figure 10

[0055] The linkage unit in the application comprises a contact plate 18 fixedly connected to the connecting plate 15, a first pressure sensor 19 fixedly installed on the partition plate 28, a motor 17 fixedly installed outside the material taking hopper 2 and a first controller 26, the motor 17 is coaxially fixedly connected to the rotating rod 5, the first pressure sensor 19 and the motor 17 are electrically coupled with the first controller 26, and a power supply box 22 is also fixedly installed outside the material taking hopper 2, and a power supply such as a lithium battery or a storage battery is installed in the power supply box 22, for providing electric quantity for the linkage unit in the embodiment two.

[0056] Further, the controller is a programmable controller, such as a programmable controller of model S7-200, the motor 17 is a self-locking motor 17, which is convenient for locking the position of the baffle 6 when driving the baffle 6 to rotate, and the first pressure sensor 19 is used for detecting the pushing force applied by the abutting plate 18, and the weight sensor of model DYLY-103 is specifically referred to.

[0057] Specifically, the principle operation is as follows: with the driving of the chain type material taking unit 1, the material taking hopper 2 takes out more material, and the material entering the material taking hopper 2 presses the tongue 4, so that the tongue 4 rotates downward to drive the rotating shaft 14 to rotate, the rotating shaft 14 drives the connecting plate 15 and the abutting plate 18 to rotate until the abutting plate 18 abuts against the first pressure sensor 19; therefore, the first pressure sensor 19 transmits a signal to the first controller 26, and the first controller 26 starts the motor 17 to work until the motor 17 drives the baffle 6 to rotate to form a block to the bottom end of the feeding port of the material taking hopper 2, so as to avoid the material from sliding.

[0058] Specifically, the principle operation is as follows: with the driving of the chain type material taking unit 1, the material taking hopper 2 takes out more material, and the material entering the material taking hopper 2 presses the tongue 4, so that the tongue 4 rotates downward to drive the rotating shaft 14 to rotate, the rotating shaft 14 drives the connecting plate 15 and the abutting plate 18 to rotate until the abutting plate 18 abuts against the first pressure sensor 19; therefore, the first pressure sensor 19 transmits a signal to the first controller 26, and the first controller 26 starts the motor 17 to work until the motor 17 drives the baffle 6 to rotate to form a block to the bottom end of the feeding port of the material taking hopper 2, so as to avoid the material from sliding.

[0059] When the chain type material taking unit 1 drives the material taking hopper 2 to take material, with the driving of the chain type material taking unit 1, when the material taking hopper 2 contacts the material, the material is scooped into the material taking hopper 2 under the driving of the chain type material taking unit 1, and with the driving of the chain type material taking unit 1, the material taking hopper 2 takes out more material, and the material entering the material taking hopper 2 presses the tongue 4, so that the tongue 4 rotates downward to drive the rotating shaft 14 to rotate, the rotating shaft 14 drives the connecting plate 15 and the abutting plate 18 to rotate until the abutting plate 18 abuts against the first pressure sensor 19.

[0060] Therefore, the first pressure sensor 19 transmits a signal to the first controller 26, and the first controller 26 starts the motor 17 to work until the motor 17 drives the baffle 6 to rotate to form a block to the bottom end of the feeding port of the material taking hopper 2, so as to avoid the material from sliding.

[0061] At this time, the material taking hopper 2 is also lifted under the driving of the chain type material taking unit 1 to prepare for discharging, and if the material taking hopper 2 is discharged, the abutting plate 18 no longer abuts against the first pressure sensor 19 under the elastic pulling of the spring 16, the first controller 26 controls the motor 17 to reverse to open the baffle 6 again to welcome the next material taking.

[0062] In summary, the embodiment can also timely form a block to the bottom end of the feeding port of the material taking hopper 2 by rotating the baffle 6 when the material taking hopper 2 is lifted to take material, so as to avoid the material from sliding.

[0063] Embodiment three

[0064] The embodiment is based on the embodiment one, and the technical scheme is increased, so as to further increase the blocking effect.

[0065] Specifically, referring to Figure 1 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 11

[0066] Further, a notch 13 is arranged at one end of the baffle 6, and an electric push rod 24 is fixedly arranged in the notch 13, and a piston rod of the electric push rod 24 is fixedly connected with a push plate 23. The outer part of the first gear 7 is fixedly connected with a cam 20, the inner wall of the shell 3 is fixedly connected with an arc-shaped elastic sheet 21, and the inner wall of the shell 3 is fixedly connected with a second pressure sensor 25 at a position corresponding to the arc-shaped elastic sheet 21.

[0067] The details are as follows

[0068] The second controller 27 can be a programmable controller, such as a programmable controller with a model number of s7-200, and the first pressure sensor 19 is used to detect the pushing force applied by the arc-shaped elastic sheet 21, and specifically refers to a weight sensor with a model number of DYLY-103. Similarly, a power box 22 is also fixedly arranged outside the material taking hopper 2, and a power source such as a lithium battery or a storage battery is arranged in the power box 22, which is used to provide power for the electric push rod 24 and the second controller 27.

[0069] Specifically, the operation is as follows

[0070] In the working process of the embodiment, when the first gear 7, the second gear 8 and the third gear 9 are driven, the baffle 6 rotates upward to achieve sealing, so that the first gear 7 can drive the cam 20 to rotate and abut against the arc-shaped elastic sheet 21.

[0071] Through the abutment of the cam 20 against the arc-shaped elastic sheet 21, the arc-shaped elastic sheet 21 can abut against the second pressure sensor 25. After the second pressure sensor 25 transmits a signal to the second controller 27, the second controller 27 can start the electric push rod 24 to work, and the electric push rod 24 pushes out a certain distance, such as 5-10 cm, but does not completely close the material taking hopper 2.

[0072] At this time, under the driving of the chain type material taking unit 1, the material taking hopper 2 is discharged. If the material taking hopper 2 is discharged, under the elastic force of the spring 16, the first gear 7 rotates back to the original position, so that the arc-shaped elastic sheet 21 is not abutted, and the second pressure sensor 25 cannot detect the pressure. At this time, the second controller 27 controls the electric push rod 24 to drive the baffle 6 to retract, so as to welcome the next material taking.

[0073] Therefore, the embodiment can realize the extension of the pushing plate 23 after the baffle 6 rotates, and further increase the material blocking effect.

[0077] The arc-shaped plate 10 is arranged to close the gap between the rotating shaft 14 and the material taking hopper 2, so as to avoid that the material is clamped between the rotating rod 5 and the material taking hopper 2 and cannot be rotated. The first rubber sleeve 11 and the second rubber sleeve 12 are arranged to protect the pressing tongue 4 and the slot 13, so as to avoid that the material is accumulated below the pressing tongue 4 and the pressing tongue 4 cannot be rotated downward. The slot 13 is closed to avoid that the material enters the other side of the partition plate 28.
