Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a feeding device for preparing coated urea. Background Technology

[0002] The urea preparation feeding device is the core equipment in the production of coated urea. It is mainly used to accurately transport urea particles to the coating stage. The drive motor is started to drive the spiral mandrel to rotate, and the feeding auger transports the urea particles from the inlet upwards and the material falls into the preparation tank through the outlet.

[0003] However, the existing urea preparation feeding device has the following shortcomings: Traditional coated urea preparation feeding devices typically have a fixed-height feeding pipe, which cannot be matched with production equipment or containers of different heights, requiring additional device replacement and affecting overall operating efficiency. Utility Model Content

[0004] The main purpose of this utility model is to provide a feeding device for the preparation of coated urea, which can effectively solve the problem that the upper support may completely detach due to the rotation or vibration of the threaded rod, resulting in support failure and causing safety accidents such as collapse and fall.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A feeding device for preparing coated urea includes a feeding outer tube, an adjustment mechanism is installed at the lower part of the feeding outer tube, and a shock absorption mechanism is installed on the left side of the feeding outer tube. The adjustment mechanism includes a support platform, a first connecting block, a first hinge block inside the support platform, a second connecting block at the lower part of the feeding outer tube, a second hinge block at the lower part of the feeding outer tube, a side end of the second connecting block hinged to the side end of the second hinge block, and two support blocks at the bottom of the second hinge block.

[0006] Preferably, the support platform is equipped with an electric telescopic rod inside, the extended end of which is located at the bottom of the first hinge block, and a support plate is provided at the bottom of the support platform, with multiple casters at the bottom of the support plate.

[0007] Preferably, an inlet pipe is provided on the upper left side of the outer feeding pipe, and a discharge pipe is provided on the lower right side of the outer feeding pipe.

[0010] Preferably, through-column plates are respectively provided on the outer sides of the left and right sides of the first support column.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting an adjustment mechanism, the electric telescopic rod drives the first hinge block to rise, the first connecting block hinges and rotates at the side end of the first hinge block, and the second connecting block hinges and rotates at the side end of the second hinge block.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figure 1 - Appendix Figure 5 As shown, a feeding device for preparing coated urea includes a feeding outer pipe 1. An adjusting mechanism 3 is mounted on the lower part of the feeding outer pipe 1, and a shock-absorbing mechanism 4 is mounted on the left side of the feeding outer pipe 1. The adjusting mechanism 3 includes a support platform 31, a first connecting block 34, a first hinge block 33 disposed inside the support platform 31, a second connecting block 35 and a second hinge block 36 disposed on the lower part of the feeding outer pipe 1, with the side end of the second connecting block 35 hinged to the side end of the second hinge block 36. Two supports are disposed at the bottom of the second hinge block 36. Block 37, the support platform 31 is equipped with an electric telescopic rod 32 inside, the extended end of the electric telescopic rod 32 is located at the bottom of the first hinge block 33, the support platform 31 is equipped with a support plate 9 at the bottom, the support plate 9 is equipped with multiple casters 10 at the bottom, the upper left side of the feeding outer pipe 1 is equipped with a feed pipe 2, the lower right side of the feeding outer pipe 1 is equipped with a discharge pipe 5, the left side of the feeding outer pipe 1 is equipped with a motor 6, the inner side of the feeding outer pipe 1 is equipped with a shaft 7, the outer side of the shaft 7 is equipped with an auger 8, and the left side of the shaft 7 is located on the right side of the output shaft of the motor 6.

[0017] The overall effect of Embodiment 1 is as follows: the relevant components can improve the traditional coating urea preparation feeding device by changing the height of the feed pipe from the container through mechanical transmission. By setting the feed pipe 5 and the second connecting block 35 to maintain a greater distance, the device covers a wider range of feed inlet heights of the preparation tank, adapting to the feeding needs of preparation tanks of different specifications. This mechanical transmission method can match production equipment or containers of different heights without the need for additional device replacement, thus improving overall operating efficiency.

[0018] Example 2, as Figures 1-5 As shown, the shock absorption mechanism 4 includes a first support column 41, with multiple springs 43 arranged on the outer side of the first support column 41. A second support column 44 is connected to the outer side of the first support column 41 through the multiple springs 43. Column plates 42 are respectively arranged on the outer sides of the left and right sides of the first support column 41. The purpose of setting a distance between the outer side of the column plate 42 and the inner side of the second support column 44 is to prevent the inner side of the second support column 44 from generating a squeezing force with the outer side of the column plate 42 when the springs 43 are elastically buffering.

[0019] The effect achieved by the entire embodiment 2 is as follows: by setting up the shock absorption mechanism 4, the outer side of the first support column 41 forms an elastic buffer with the second support column 44 through multiple springs 43, which provides shock absorption protection for subsequent operation.

[0020] The feeding outer pipe 1 is pushed, and the device is moved to the target station for urea coating preparation via multiple casters 10 at the bottom of the support plate 9, so that the feeding pipe 5 is aligned with the inlet of the preparation tank. Then, the casters 10 are locked, and the electric telescopic rod 32 inside the support platform 31 is controlled to extend and retract. The extended end of the electric telescopic rod 32 pushes the first hinge block 33 to move up and down, which in turn drives the feeding outer pipe 1 to rotate around the second hinge block 36 via the first connecting block 34. At this time, the outer side of the first connecting block 34 is hinged to the side end of the first hinge block 33, and the second connecting block 35 is hinged to the inside of the side end of the second hinge block 36. The first support column 4... 1. The feed tube 1 is fixed to the left side by the through-column plates 42 on both sides. Multiple springs 43 on the outside of the feed tube 1 and the second support column 44 form an elastic buffer structure to provide shock absorption protection for subsequent operation. The operator starts the motor 6. The output shaft of the motor 6 drives the shaft 7 inside the feed tube 1 to rotate. The auger 8 outside the shaft 7 rotates synchronously. The urea granules raw material enters the feed tube 1 through the feed pipe 2. The rotating auger 8 transports the raw material from the left to the right and finally falls accurately into the preparation tank through the discharge pipe 5 to achieve continuous feeding. The vibration generated during the operation of the motor 6 and the raw material transportation process is transmitted to the shock absorption mechanism 4.
