Description

Technical Field

[0001] This utility model relates to the field of feeding machine technology, specifically a biomass pellet feeding machine. Background Technology

[0002] Biomass pellets are produced by cold-forming and densifying crushed biomass straw, forestry waste, and other raw materials using pressure rollers and ring dies at room temperature. The density of the raw materials is generally 0.1–0.13 t / m³, while the density of the pellets after forming is 1.1–1.3 t / m³, which facilitates storage and transportation and greatly improves the combustion performance of biomass.

[0003] According to patent authorization announcement number CN212333765U, a biomass pellet feeder includes a feed inlet. A motor is fixedly connected to the top of a horizontal block. A first grooved wheel is rotatably connected to a second grooved wheel via a belt. A rotating tooth is fixedly connected to the right end of the second grooved wheel, and the rotating tooth is rotatably connected to the housing via a first bearing. This biomass pellet feeder allows the rotating tooth to continuously transport material to the right, and the material is discharged from the lower right outlet of the housing, completing the feeding process. This increases the feeding speed and solves the problem of slow feeding speed in existing biomass pellet feeders due to indirect feeding, which affects processing speed. The screw rotation drives the vertical pipe to move up and down, adjusting the height of the right side of the housing. This broadens the application range and solves the problem of existing biomass pellet feeders being limited in their application range because they cannot be adjusted according to the required feeding height.

[0004] However, in the existing technology, when the feeding hopper of the feeder is feeding biomass pellets, a large amount of biomass pellets are discharged from the bottom of the feeding hopper onto the conveying device, and then transported by the conveying device. Because a large amount of material falls and moves onto the conveying device at the same time, it causes compression of the conveying device. Long-term repeated compression can easily damage the conveying device. At the same time, when the feeder discharges biomass pellets, the biomass pellets fall from the discharge port into the container, and the biomass pellets falling from a height can easily cause impact damage to the container. Utility Model Content

[0005] The purpose of this invention is to provide a biomass pellet feeder that solves the problems of biomass pellet discharge efficiency and protection of external containers.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a biomass pellet feeder, comprising a conveying cylinder, a feed hopper fixedly connected to the upper side of the lower end of the conveying cylinder, a plurality of support legs fixedly connected to the conveying cylinder, ear plates fixedly connected to the lower ends of the support legs, rollers rotatably connected to the ear plates, an adjustment mechanism provided at the lower end of the feed hopper, and a protective mechanism provided at the upper end of the conveying cylinder.

[0007] Preferably, the adjusting mechanism includes a baffle, the baffle is slidably connected to the lower end of the inside of the feed hopper, and anti-detachment blocks are fixedly connected to the upper and lower ends of the right side of the baffle.

[0008] Preferably, the anti-detachment block is slidably connected to the lower end of the feed hopper, and the lower end of the baffle is provided with multiple threaded grooves, and the inside of the threaded grooves is connected to a threaded pin by a threaded rotation.

[0009] Preferably, a pull block is fixedly connected to the left side of the threaded pin, and a sleeve is fixedly connected to the lower left side of the feed hopper. The baffle slides through the inside of the sleeve.

[0010] Preferably, the protective mechanism includes a telescopic sleeve, the right side of the conveying cylinder is fixedly connected to the telescopic sleeve, and the lower end of the telescopic sleeve is fixedly connected to a sleeve.

[0011] Preferably, a plurality of spring plates are fixedly connected inside the sleeve, and an ear plate is fixedly connected to the right side of the sleeve.

[0012] Preferably, a telescopic rod is fixedly connected to the upper end of the ear plate, and the upper end of the telescopic rod is fixedly connected to the right side of the conveying cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model features multiple threaded grooves at the lower end of the baffle. The threaded grooves are connected to threaded pins via threaded rotation. The threaded pins pass through the lower end of the sleeve via threaded rotation, facilitating the left and right movement of the baffle. This allows control of the flow area at the lower end of the feed hopper, thus controlling the amount of material falling. This prevents excessive material falling and pressing down on the lower end of the conveyor cylinder, which could damage the structure and affect the performance and service life.

[0015] 2. This utility model connects the lower end of the telescopic rod to the ear plate, and the ear plate is connected to the sleeve, so that the telescopic sleeve can be extended and retracted up and down. Then the contact distance between the sleeve and the external container can be adjusted. The material falls onto the spring plate and then falls into the interior of the external container, avoiding the impact damage to the external container caused by the material falling from a large distance.

[0024] Please see Figure 1 , Figure 2 A biomass pellet feeder includes a conveying cylinder 1. The conveying cylinder 1 is existing technology, and its working principle is also existing technology, so this technical solution will not be described in detail here. A feed hopper 2 is fixedly connected to the upper side of the lower end of the conveying cylinder 1. Multiple support legs 3 are fixedly connected to the conveying cylinder 1. Ear plates 4 are fixedly connected to the lower end of the support legs 3. The support legs 3 and ear plates 4 are used to support and limit the conveying cylinder 1. Rollers 5 are rotatably connected to the ear plates 4. The rollers 5 are used to facilitate the conveying and moving of the conveying cylinder 1. An adjustment mechanism 6 is provided at the lower end of the feed hopper 2, and a protective mechanism 7 is provided at the upper end of the conveying cylinder 1.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6The adjusting mechanism 6 includes a baffle 61. The baffle 61 is slidably connected to the lower end of the feed hopper 2. Anti-detachment blocks 62 are fixedly connected to the upper and lower ends of the right side of the baffle 61. The anti-detachment blocks 62 prevent the baffle 61 from detaching from the lower end of the feed hopper 2. The anti-detachment blocks 62 are slidably connected to the lower end of the feed hopper 2. The lower end of the baffle 61 is provided with multiple threaded grooves 63. The threaded grooves 63 are connected to the threaded pins 64 by threaded rotation. The left side of the threaded pins 64 is fixedly connected to a pull block 65. The pull block 65 facilitates the left and right movement of the baffle 61. The lower left side of the feed hopper 2 is fixedly connected to a sleeve 66. The baffle 61 slides through the inside of the sleeve 66.

[0026] Please see Figure 1 , Figure 2 , Figure 5 The protective mechanism 7 includes a telescopic sleeve 71. The telescopic sleeve 71 is fixedly connected to the right side of the conveying cylinder 1. A sleeve 72 is fixedly connected to the lower end of the telescopic sleeve 71. The telescopic sleeve 71 facilitates the stretching of the telescopic sleeve 71 to lower the sleeve 72, which facilitates up-and-down movement and limits the position of the sleeve 72. Multiple spring plates 73 are fixedly connected inside the sleeve 72. An ear plate 74 is fixedly connected to the right side of the sleeve 72. A telescopic rod 75 is fixedly connected to the upper end of the ear plate 74. The telescopic rod 75 is model YNT-03.

The upper end of the telescopic rod 75 is fixedly connected to the right side of the conveying cylinder 1.

[0027] The specific implementation process of this utility model is as follows: In use, the conveying cylinder 1 is started, making the conveying cylinder 1 of the prior art work. Then, the biomass pellets are put into the inside of the feed hopper 2, and then moved to the upper end of the conveying cylinder 1 through the internal conveying. Then, they are discharged through the telescopic sleeve 71 and the sleeve 72. By removing the threaded pin 64, the baffle 61 can be moved left and right. When it is moved to a suitable position, the limiting threaded pin 64 is inserted to limit and fix the baffle 61, thereby achieving the effect of adjusting the size of the feeding area. By starting the telescopic rod 75, the telescopic rod 75 drives the ear plate 74 to move downward. Then, the sleeve 72 drives the telescopic sleeve 71 to move downward. Then, the telescopic rod 71 is stretched and moved downward, so that the biomass pellets can be fed. The material falls onto the spring plate 73 and then falls into the external container, thereby reducing the impact damage caused by the falling material to the external container.
