Description

Technical Field

[0001] The utility model relates to the field of auger conveying equipment, in particular to an auger feeding device. Background Art

[0002] Feeding augers are widely used in material conveying, but with the development of the industry, the industry's requirements for material conveying accuracy and efficiency are becoming increasingly higher. In conventional theory, larger feeding augers should have higher conveying efficiency, but their batching accuracy is relatively low; smaller augers have higher batching accuracy, but their conveying efficiency should be lower. Based on this theory, most companies use a combination of the two, but in actual use, they find that small augers not only have low conveying efficiency, but also make it difficult to ensure quantitative feeding, which makes it difficult to control batching accuracy. This is determined by the structure of the auger. When conveying, the spiral blades of traditional augers have an upward force on the material, making it difficult to ensure the consistency of the filling degree during material conveying. At the end of batching, it is difficult to ensure that the material does not fall from the outlet when the auger stops, which will affect the accuracy of the batching.

[0003] Therefore, how to propose a auger feeding device that can accurately distribute materials has become a technical problem that urgently needs to be solved in the industry. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the deficiencies in the prior art, the utility model provides a screw feeding device that can precisely distribute materials.

[0005] Technical solution: An auger feeding device, comprising:

[0006] An auger mechanism, wherein a discharge cavity is provided at the end of the auger mechanism, and a blocking mechanism is provided in the discharge cavity for closing the opening at the end of the auger mechanism;

[0007] The quantitative feeding mechanism provided on one side of the auger mechanism comprises:

[0008] A feeding chamber is connected to the auger mechanism, and a slider that can move between a first position and a second position is provided at the bottom of the feeding chamber. A feed trough is provided on the slider. When the slider moves to the first position, the feed trough is aligned with the feeding chamber, and the feeding chamber feeds the feed trough. When the slider moves to the second position, the slider enters the discharge chamber, the feed trough outputs the material to the discharge chamber, and the slider closes the bottom of the feeding chamber.

[0009] Furthermore, the material-blocking mechanism includes a material-blocking flange for being sleeved on the main shaft of the auger mechanism, and a first cylinder is provided on the discharge chamber. The first cylinder drives and connects the material-blocking flange to drive the material-blocking flange to move along the main shaft direction.

[0010] Furthermore, the slider is sleeved in a horizontal track, and a second cylinder is provided at the front end of the horizontal track. The second cylinder drives and connects the slider to push out or pull back the slider.

[0011] Furthermore, the material discharge cavity is configured to be provided with at least one inclined surface.

[0012] Furthermore, the horizontal track is a shell surrounded on four sides, the slider is sleeved in the shell, and sealing rings are sleeved on the front and rear ends of the slider.

[0013] Beneficial Effects: This new auger feeding device utilizes a movable blocking mechanism and a slider. The blocking mechanism blocks the auger discharge port when the auger is nearing completion of feeding, while the feed trough provided on the slider delivers quantitative material. This method achieves both efficient feeding and precise batching, boasts a compact structure, strong device integrity, and flexible interchangeability, allowing for the flexibly replaced quantitative feed sliders according to precision requirements.

[0018] See also Figure 1-2An embodiment of the auger feeding device of the present invention shown in the figure comprises: an auger mechanism 1, a quantitative feeding mechanism disposed on one side of the auger mechanism 1, and a material discharge chamber 4 connected to the auger mechanism 1. A discharge chamber 9 is provided at the end of the auger mechanism 1 to receive material 6 output from the end opening of the auger mechanism 1. A material blocking mechanism is provided in the discharge chamber 9 to close the end opening of the auger mechanism 1.

[0019] The bottom of the feeding chamber 4 is provided with a slider 17 which can move between a first position and a second position. The slider 17 is provided with a feeding trough 21. When the slider 17 moves to the first position, Figure 1 As shown, the feeding trough 21 is aligned with the feeding cavity 4, and the feeding cavity 4 feeds the feeding trough 21. When the slider 17 moves to the second position, as shown in FIG. Figure 2 As shown, the slider 17 enters the discharge cavity 9 , the feed trough 21 outputs the material to the discharge cavity 9 , and the slider 17 closes the bottom of the feed cavity 4 .

[0020] By providing a movable material blocking mechanism and a slider 17, the material blocking mechanism blocks the material outlet of the auger mechanism 1 when the auger mechanism 1 is close to completing material feeding, and the material feeding trough 21 provided on the slider 17 is used to quantitatively convey the material. This method satisfies both conveying efficiency and material batching accuracy, has a compact structure, and has a strong sense of equipment integrity. In addition, the quantitative feeding slider 17 can be flexibly replaced according to the accuracy requirements, and has strong interchangeability.

[0021] Specifically, the feed chute 21 is a through-channel structure, and the slider 17 is sleeved within a horizontal track. A second cylinder 12 is provided at the front end of the track. The second cylinder 12 drives the slider 17 to push or pull it back. When the feed chute 21 is located below the discharge chamber 4, it receives the material discharged from the discharge chamber 4. When the feed chute 21 is moved to the discharge chamber 9, the material falls from the opening below the feed chute 21.

[0022] In some preferred embodiments, the material-blocking mechanism includes a material-blocking flange 3 for being sleeved on the main shaft 2 of the auger mechanism 1. A first cylinder 8 is provided on the discharge chamber 9. The first cylinder 8 is driven and connected to the material-blocking flange 3 to drive the material-blocking flange 3 to move along the main shaft 2. By sleeved on the main shaft 2, the main shaft 2 is used as a guide mechanism, so that the material-blocking flange 3 and the end opening of the auger mechanism 1 remain concentric, thereby improving the accuracy of the closure.

[0023] It is worth noting that the first cylinder 8 and the second cylinder 12 are both preferred solutions of this embodiment. In other embodiments, they can also be replaced by other linear reciprocating motion mechanisms such as screw-nut mechanisms, hydraulic cylinders, etc., which will not be elaborated here.

[0024] In some preferred embodiments, the material discharge chamber 4 is configured to have at least one inclined surface, so as to avoid the gravity of the material being entirely concentrated on the slider 17 , thereby improving the durability of the slider 17 .

[0025] In some preferred embodiments, the horizontal track is a housing 7 surrounded on all sides, the slider 17 is sleeved within the housing 7, and sealing rings 5 ​​are sleeved on both the front and rear ends of the slider 17. The provision of the sealing rings 5 ​​prevents material from sticking to the gap between the slider 17 and the housing, thereby improving the accuracy of material transportation and avoiding material waste.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
