DETAILED DESCRIPTION

[0018] The embodiment of the present application discloses a movable material cart which is convenient for the maintenance of the automatic conveying system. Through the elastic force of the spring 63, when the mounting column 61 is inserted into the mounting groove 21, the limit block 62 extends into the limit groove 31, and the discharge pipe 20 and the feed pipe 70 are fixed together. When disassembling, it is only necessary to press the two insertion rods 64 to move the feed pipe 70 out from the bottom of the discharge pipe 20, which makes installation and disassembly more convenient, so that the silo 40 can be easily moved out from the bottom of the dryer 10 for feeding, and will not affect the maintenance of the dryer 10.

[0019] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0020] Please refer to Figure 1 and Figure 2 The present embodiment provides a movable material cart that is convenient for the maintenance of the automatic conveying system, including a silo 40 at the bottom of the dryer 10, a discharge pipe 20 fixedly provided at the bottom of the dryer 10, a feed pipe 70 provided at the top of the silo 40, a sealing gasket 80 fixedly provided at the top of the feed pipe 70, the sealing gasket 80 is provided between the discharge pipe 20 and the feed pipe 70, the sealing gasket 80 is sleeved on the outside of two mounting columns 61, four electric push rods 50 are fixedly provided at the bottom of the silo 40, a mounting groove 21 is provided at the bottom of the discharge pipe 20, a mounting assembly 60 is provided on the silo 40 and the feed pipe 70, and the mounting assembly 60 is provided on the mounting assembly 60. It includes a mounting column 61, a limit block 62, a spring 63, an insert rod 64, and a slider 65. The two mounting columns 61 are symmetrically arranged on both sides of the top of the feed pipe 70. The mounting columns 61 match the size of the mounting groove 21. The feed pipe 70 can be raised to a position close to the discharge pipe 20 by the extension and retraction of the four electric push rods 50, and the mounting columns 61 can also be extended into the mounting groove 21 to position the installation of the discharge pipe 20 and the feed pipe 70. The connection between the discharge pipe 20 and the feed pipe 70 is sealed by the sealing gasket 80 between the discharge pipe 20 and the feed pipe 70 to prevent powder leakage during transportation.

[0021] Please refer to Figure 1 、 Figure 2 and Figure 3The limit block 62 is inserted and connected to the outside of the mounting column 61. The mounting column 61 is fixed to the inside of the discharge pipe 20 through the limit block 62. A groove 611 is provided on the outside of the top of the mounting column 61. The limit block 62 is slidably connected to the inside of the groove 611. The spring 63 is provided inside the groove 611. The two ends of the spring 63 are respectively fixedly connected to the inner wall of the groove 611 and the limit block 62. The two sides of the discharge pipe 20 are fixedly provided with a fixing seat 30. The fixing seat 30 has a limiting groove 3 provided inside. 1. The limiting groove 31 is connected to the mounting groove 21. The limiting groove 31 matches the size of the limiting block 62. A transition groove 22 is provided at the bottom of the mounting groove 21. The inner wall of the transition groove 22 is in contact with the limiting block 62. Through the contact between the inner wall of the transition groove 22 and the limiting block 62, when the mounting column 61 is extended into the mounting groove 21, the inclined surface of the limiting block 62 can exert pressure on the limiting block 62, so that the limiting block 62 is retracted into the groove 611, and the mounting column 61 can be smoothly inserted into the interior of the mounting groove 21.

[0022] Please refer to Figure 1 、 Figure 2 and Figure 3 The insertion rod 64 is slidably connected to the inside of the limit groove 31, and one end of the insertion rod 64 is in contact with the limit block 62. A slide groove 32 is provided on both sides of the limit groove 31. Two sliders 65 are fixedly provided on both sides of the insertion rod 64. The two sliders 65 are slidably connected to the inside of the two slide grooves 32. The bottom of the electric push rod 50 is provided with a roller, which can drive the hopper 40 to move out of the dryer 10. The sliding of the sliders 65 on both sides of the insertion rod 64 in the slide groove 32 limits the movement of the insertion rod 64 to prevent the insertion rod 64 from separating from the limit groove 31. By pressing the insertion rod 64, the material hopper 40 can be moved out of the dryer 10. The insertion rod 64 can slide in the limit groove 31, and the insertion rod 64 can squeeze the limit block 62, so that the limit block 62 extends into the inside of the groove 611, thereby releasing the fixation between the discharge pipe 20 and the feed pipe 70, so that the electric push rod 50 contracts and drives the feed pipe 70 to move downward, so that the feed pipe 70 can be separated from the discharge pipe 20, and the disassembly of the mobile trolley is completed, so that the mobile trolley is moved out of the bottom of the dryer 10 by the roller, which is convenient for the maintenance of the dryer 10. The powder stored in the silo 40 can also be temporarily fed to the kiln without affecting the normal powder transportation process.

[0023] This application can explain its functional principles through the following operation methods:

[0024] When in use, the material bin 40 and the feeding pipe 70 are pushed to the bottom of the discharging pipe 20 by the rollers, so that the two mounting posts 61 at the top of the feeding pipe 70 are aligned with the two mounting grooves 21 at the bottom of the discharging pipe 20, and the electric push rod 50 is started, so that the electric push rod 50 drives the feeding pipe 70 to move upward, so that the two mounting posts 61 are inserted into the mounting grooves 21 from the transition grooves 22, and the limit blocks 62 on the outside of the two mounting posts 61 are retracted into the grooves 611 by the pressure of the inclined surface of the transition groove 22, so that the mounting posts 61 can smoothly extend into the interior of the mounting grooves 21. When the feeding pipe 70 is raised to the top and the sealing gasket 80 is tightly attached to the discharging pipe 20, the limit block 62 moves to the position of the limit groove 31 inside the fixing seat 30, and the elastic force of the spring 63 inside the groove 611 causes the limit block 62 to extend into the limit groove 31, pushing out the insertion rod 64 originally inside the limit groove 31, and the two insertion rods 64 are pushed out. The slider 65 on the side slides along the slide groove 32, and the slide groove 32 prevents the insertion rod 64 from moving out of the limit groove 31, so that the discharge pipe 20 and the feed pipe 70 are fixedly installed together, and the powder in the dryer 10 can be input into the hopper 40 through the discharge pipe 20 and the feed pipe 70, and then output to the kiln. When the dryer 10 needs to be repaired, the two insertion rods 64 are pressed, so that the two insertion rods 64 drive the two limit blocks 62 to slide in the limit groove 31, so that the two limit blocks 62 retract into the groove 611, and the electric push rod 50 is started to move the feed pipe 70 downward, driving the installation column 61 to move out of the installation groove 21, so that the discharge pipe 20 is separated from the feed pipe 70, and the hopper 40 is moved out of the bottom of the dryer 10 by the roller, and the dryer 10 is repaired. The powder in the hopper 40 can also be temporarily fed to the kiln without affecting the normal powder transportation process.

Thus, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalents, this application is intended to include these modifications and variations.
