[0005] When biomass raw materials such as rice straw, wheat straw, branches, and weeds are fed into the storage chamber through the hopper at the top of the storage chamber, the biomass raw materials are easily blocked in the hopper, resulting in difficulty in feeding. Utility Model Content

[0006] In order to avoid as much as possible the blockage of biomass raw materials when entering the storage chamber and improve the convenience of feeding, the present application provides a feeding device for a biomass gasifier.

[0007] The present application provides a feeding device for a biomass gasifier, which adopts the following technical solution:

[0008] A feeding device for a biomass gasifier comprises a feeding pipe, wherein the length direction of the feeding pipe is distributed in a vertical direction, one end of the feeding pipe is used to communicate with the top of a storage chamber, a pushing plate is provided in the feeding pipe, the length direction of the pushing plate is consistent with the length direction of the feeding pipe, and the pushing plate is slidingly connected to the inner wall of the feeding pipe along the length direction of the feeding pipe.

[0009] By adopting the above technical solution, after the biomass raw materials enter the feed pipe, the push plate slides in the feed pipe along the length direction of the feed pipe, which can drive the biomass raw materials to be transported to the storage chamber, thereby avoiding blockage of the biomass raw materials when entering the storage chamber and improving the convenience of feeding.

[0010] Preferably, the push plate includes a movable plate and a push plate, the movable plate is slidingly connected to the inner wall of the feed tube, there are multiple push plates, each of the push plates is evenly spaced on the movable plate, one end of the push plate is hinged to the movable plate, and the other end of the push plate is connected to a driving member for adjusting the angle between the push plate and the movable plate.

[0011] By adopting the above technical solution, when the movable sheet moves toward the storage chamber, the driving member drives the pushing sheet, the angle between the pushing sheet and the movable sheet becomes larger, and the pushing sheet pushes the biomass raw material into the storage chamber. When the movable sheet moves away from the storage chamber, the driving member adjusts the angle between the pushing sheet and the movable sheet to become smaller, thereby avoiding as much as possible that the movable sheet drives the biomass raw material to be transported to the top of the feed pipe when moving.

[0012] Preferably, a sliding hole is opened on the side wall of the feed pipe, the length direction of the sliding hole is consistent with the length direction of the feed pipe, the movable plate is moved by the first cylinder, the length direction of the piston rod of the first cylinder is consistent with the length direction of the sliding hole, and the piston rod of the first cylinder is connected to the movable plate through a connecting block.

[0013] By adopting the above technical solution, when the first cylinder moves the connecting block in the vertical direction, the connecting block can slide in the sliding hole, thereby driving the moving plate to move along the length direction of the feed pipe, and the moving plate can drive the pushing plate, and the pushing plate can push the biomass raw material to be transported to the storage chamber.

[0014] Preferably, the driving member is a spring, one end of the spring is connected to a side of the pushing plate facing the moving plate, and the other end of the spring is connected to the moving plate.

When the moving piece moves toward the storage chamber, the bottom of the pushing piece can push the biomass raw material in the direction of the storage chamber. When the moving piece moves away from the storage chamber, if there is still biomass raw material in the feed pipe, the biomass raw material resists the pushing piece, the spring is compressed, and the angle between the pushing piece and the moving piece becomes smaller, which can avoid the pushing piece from moving the biomass raw material away from the storage chamber as much as possible.

[0019] By adopting the above technical solution, the second cylinder drives the pushing rod to pass through the opening and push the pushing piece. After one end of the pushing piece is pushed away from the moving piece, the angle between the pushing piece and the moving piece becomes larger. When the pushing piece and the moving piece move toward the storage chamber together, the bottom of the pushing piece and the end of the pushing rod can push the biomass raw material together. After the second cylinder drives the pushing rod to retract, the biomass raw material resists the pushing piece, and the pushing piece rotates into the opening, and the angle between the pushing piece and the moving piece becomes smaller.

[0026] 2. The spring can push the pushing piece, and the angle between the pushing piece and the moving piece becomes larger.

[0038] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0039] The embodiment of the present application discloses a feeding device for a biomass gasifier.

[0040] Embodiment 1:

[0041] Reference Figure 1 and Figure 2 The feeding device of the biomass gasifier includes a feeding pipe 200, which is used to communicate with the storage chamber 100. A pushing plate 300 is provided in the feeding pipe 200. The pushing plate 300 is slidably connected to the feeding pipe 200. The pushing plate 300 is used to push the biomass raw material toward the storage chamber 100, which can avoid the blockage of the biomass raw material when entering the storage chamber 100 as much as possible, thereby improving the convenience of feeding.

[0042] The feed pipe 200 is a square tube, and its length direction is distributed along the vertical direction. The bottom end of the feed pipe 200 is used to communicate with the top of the storage chamber 100. A top cover 202 is hinged on the top of the side wall of the feed pipe 200, and the top cover 202 rotates to close or open the top opening of the feed pipe 200.

[0043] Reference Figure 2 and Figure 3 There are two push plates 300 and they are distributed on the two side walls facing the feed pipe 200. The push plate 300 includes a moving piece 301 and a pushing piece 302. The moving piece 301 is in a rectangular plate shape. The length direction of the moving piece 301 is consistent with the length direction of the feed pipe 200. The side wall of the feed pipe 200 is provided with a sliding hole 201. The length direction of the sliding hole 201 is consistent with the length direction of the feed pipe 200. A connecting block 304 is connected to one side of the movable sheet 301, and the connecting block 304 is connected to the first cylinder 303 after passing through the sliding hole 201. The length direction of the piston rod of the first cylinder 303 is divided along the vertical direction. The piston rod of the first cylinder 303 is connected to the connecting block 304, and the shell of the first cylinder 303 is used to connect to the top of the storage chamber 100. The piston rod of the first cylinder 303 drives the connecting block 304 to move along the length direction of the sliding hole 201, and the connecting block 304 drives the movable sheet 301 to be slidingly connected with the inner wall of the feeding pipe 200 along the vertical direction.

[0044] There are multiple push pieces 302. In the present embodiment, there are six push pieces 302 and they are all in the shape of rectangular sheets. The six push pieces 302 are evenly spaced and distributed on the side of the moving piece 301 away from the inner wall of the feed pipe 200. In the present embodiment, each push piece 302 is distributed in three rows and two columns. Six receiving grooves 306 are provided on the side of the moving piece 301 away from the inner wall of the feed pipe 200. The distribution mode of the six receiving grooves 306 is the same as that of the push piece 302, and each receiving groove 306 corresponds to each push piece 302 one by one. One end of the push piece 302 along the length direction is hinged to the side wall of the receiving groove 306, and the push piece 302 is driven to rotate by a driving member to adjust the angle between the push piece 302 and the moving piece 301.

[0045] In this embodiment, the driving member adopts a spring 305, and the movable plate 301 is provided with a spring groove 307, which is connected to the bottom wall of the accommodating groove 306. One end of the spring 305 is located in the spring groove 307 and connected to the bottom of the spring groove 307. The other end of the spring 305 passes through the accommodating groove 306 and is connected to the side of the pushing plate 302 facing the movable plate 301.

[0046] The implementation principle of Example 1 is as follows: when the biomass raw material is input into the storage chamber 100 through the feed pipe 200 at the top of the storage chamber 100, the first cylinder 303 drives the moving sheet 301 to move toward the storage chamber 100, the spring 305 pushes the push sheet 302, the angle between the push sheet 302 and the moving sheet 301 becomes larger, and the bottom of the push sheet 302 can push the biomass raw material to be transported into the storage chamber 100, which can avoid the blockage of the biomass raw material when entering the storage chamber 100 as much as possible, and improve the convenience of feeding the biomass raw material. The first cylinder 303 drives the moving sheet 301 to move away from the storage chamber 100, and the biomass raw material can push the push sheet 302 into the receiving groove 306, the spring 305 is compressed to the spring groove 307, and the angle between the push sheet 302 and the moving sheet 301 becomes smaller, which can avoid the moving sheet 301 from transporting the biomass raw material to the top outlet of the feed pipe 200 when moving.

[0047] Embodiment 2: The difference between the embodiment 2 and embodiment 1 is that the driving member is different.

[0048] Reference Figure 4 and Figure 5 The feeding device of the biomass gasifier includes a push plate 300 and a driving member. The push plate 300 includes a moving sheet 301 and a plurality of push sheets 302. The moving sheet 301 is provided with a plurality of openings 308, and each opening 308 is distributed in three rows and two columns. One end of the push sheet 302 along the length direction is hinged to the side wall of the opening 308.

[0049] Reference Figure 5 and Figure 6The driving member adopts a push rod 309, and the length direction of the push rod 309 is distributed in the horizontal direction and is perpendicular to the length direction of the feeding pipe 200.

[0050] There are multiple push rods 309, and one end of each push rod 309 passes through the opening 308 after passing through the connecting block 304 to push the push sheet 302. The push sheet 302 rotates to change the angle between the push sheet 302 and the moving sheet 301. The connecting block 304 is connected to a second cylinder 312, and the length direction of the piston rod of the second cylinder 312 is consistent with the length direction of the push rod 309. The piston rod of the second cylinder 312 is connected to each push rod 309 through a connecting rod, so that each push rod 309 can be pushed together.

[0051] The inner wall of each opening 308 is connected to a first magnetic strip 310, and the end of each pushing piece 302 away from the hinged end with the movable piece 301 is connected to a second magnetic strip 311. The length direction of the first magnetic strip 310 and the second magnetic strip 311 is consistent with the width direction of the pushing piece 302. When the second cylinder 312 drives the pushing rod 309 to be pulled out of the opening 308, the pushing piece 302 rotates, and the first magnetic strip 310 and the second magnetic strip 311 approach and attract each other, thereby closing the opening 308.

[0052] The implementation principle of the second embodiment is as follows: the second cylinder 312 drives the push rod 309 to reciprocate in the opening 308, and the angle between the push sheet 302 and the moving sheet 301 can be adjusted. When the push rod 309 pushes the push sheet 302, the angle between the push sheet 302 and the moving sheet 301 becomes larger, and when the push rod 309 is pulled out of the opening 308, the angle between the push sheet 302 and the moving sheet 301 becomes smaller.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
