Description

Technical Field

[0001] This utility model relates to the field of feed feeding, and in particular to a plug-in feed feeding machine. Background Technology

[0002] Existing feed towers have a discharge port at the bottom, and a feeder is fixedly installed at the discharge port. The feeder is usually fixedly connected to the feed line pipe. When the feed is conveyed, the feed line pipe will vibrate, and the vibration will be transmitted to the feed tower. This vibration will affect the sensor that detects the weight of the feed tower, resulting in inaccurate data. Consequently, the weight of the feed dispensed will be deviated, affecting normal quantitative feeding.

[0003] Currently, some feeding machines use flexible connections made of rubber or other elastic materials at both ends to reduce vibration transmitted from the pipeline to the material tower. However, due to continuous vibration during use, the rubber in these flexible connections will age over time. Aging rubber can break, leading to a risk of material leakage, so regular replacement of the rubber connectors is necessary. Utility Model Content

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and examples: The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. like Figures 1 to 6 As shown, a plug-in type feeder includes: a housing 1, a feed pipe 2, a fixed plate 3, and a sliding plate 23. A discharge pipe 12 is formed below the housing 1, and an inlet pipe 22 is formed above the feed pipe 2. The discharge pipe 12 is inserted into the inlet pipe 22, connecting the housing 1 and the feed pipe 2. An annular first gap exists between the discharge pipe 12 and the inlet pipe 22. The housing 1 is fixedly connected to the fixed plate 3, and the feed pipe 2 is fixedly connected to the sliding plate 23. The sliding plate 23 is slidably connected to the fixed plate 3. The housing 1 is located below the discharge port of the feed tower and is fixedly connected to the feed tower. Both ends of the feed pipe 2 are fixedly connected to the feed line pipes, and a drive mechanism such as a stopper disc can pass through both ends of the feed pipe 2.

[0021] During material feeding, the vibration of the feed line section causes the feed pipe 2, which is fixed to it, to also vibrate. Due to the existence of the first gap, the discharge pipe 12 does not contact the inlet pipe 22, so the discharge pipe 12 does not vibrate with the feed pipe 2. The housing 1 itself does not vibrate, so it does not drive the connected material tower to vibrate, which improves the stability of the material tower, improves the accuracy of the weight sensor installed on the material tower, and thus improves the weight accuracy of the feeding.

[0022] Preferably, the front and rear sides of the housing 1 are fixedly connected to the fixing plates 3, and the front and rear sides of the material tube 2 are fixedly connected to the sliding plates 23, with the fixing plates 3 and sliding plates 23 corresponding one-to-one. The fixing plates 3 and sliding plates 23 at both ends prevent the fixing plates 3 and sliding plates 23 from being subjected to force on one side, resulting in less stress and a longer service life. Simultaneously, the fixing plates 3 and sliding plates 23 at both ends also serve to limit the displacement of the material tube 2 relative to the housing 1.

[0023] Preferably, the left and right sides of the housing 1 are fixedly connected to the fixing plate 3 respectively, and the left and right sides of the material tube 2 are fixedly connected to the sliding plate 23 respectively, with the fixing plate 3 and the sliding plate 23 corresponding one-to-one.

[0024] Preferably, it further includes a connecting mechanism for limiting the displacement of the sliding plate 23 relative to the fixed plate 3. With four fixed plates 3 and four sliding plates 23, the force on each pair of fixed plates 3 and sliding plates 23 is smaller.

[0025] Preferably, the connecting mechanism includes bolts 4 and nuts 5. The fixing plate 3 has a vertical elongated hole 30. The bolt 4 passes through the elongated hole 30 and the sliding plate 23 and is threadedly connected to the nut 5. The four pairs of fixing plates 3 and sliding plates 23, through their corresponding connecting mechanisms, can limit the translational range of the material tube 2 relative to the housing 1 in three directions.

[0026] It should be noted that the enlarged portions of the nut 5 and bolt 4 can be fitted flush with the fixing plate 3 or have a small gap. The diameter of the bolt 4 can be equal to or slightly smaller than the width of the elongated hole 30.

[0027] Preferably, the sidewall of the discharge pipe 12 is vertical and / or inclined inward from top to bottom, and the sidewall of the feed pipe 22 is vertical and / or inclined outward from top to bottom; the fixing plate 3, the discharge pipe 12, the feed pipe 22, and the sliding plate 23 are made of rigid material. The inclined sidewall of the discharge pipe 12 or the feed pipe 22 facilitates the insertion of the discharge pipe 12 into the feed pipe 22 during installation.

[0028] Preferably, the minimum spacing of the first gap is 1.2mm-2.0mm.

[0029] It should be noted that the spacing of the first gap can be fixed (e.g., Figure 4 and Figure 6 As shown), it can also be gradually changed (e.g. Figure 5 As shown in the figure, the minimum spacing is the minimum value of the first gap. A reasonable minimum value of the first gap can reduce the entry of foreign objects 2 into the first gap while reducing the vibration transmitted to the discharge pipe 12. Preferably, this feeder is more suitable for granular feed.

[0030] Preferably, the system further includes a first baffle 81 and a second baffle 82. The front and rear sides of the housing 1 are fixedly connected to the first baffle 81, respectively. The front and rear sidewalls of the feed pipe 22 are located between the first baffle 81 and the discharge pipe 12. The left and right sides of the housing 1 are fixedly connected to the second baffle 82, respectively. The left and right sidewalls of the feed pipe 22 are located between the second baffle 82 and the discharge pipe 12. The first baffle 81 and the second baffle 82 are in contact, and together they cover the upper opening of the first gap. The first baffle 81 and the second baffle 82 are used to prevent solid and liquid foreign objects from entering the first gap and to avoid contamination of the feed in the feed pipe 2.

[0031] Preferably, the discharge pipe 12 further includes a main pipe 21, which is located below the feed pipe 22 and is fixedly connected to the feed pipe 22. The interior of the main pipe 21 is connected to the lower opening of the feed pipe 22.

[0032] Preferably, the system further includes a rotor 6, a motor 7, and a rotating shaft 61. The housing 1 also includes a feeding section 11 and a funnel 13. The upper and lower ends of the feeding section 11 are fixedly connected to and communicate with the funnel 13 and the discharge pipe 12, respectively. The two ends of the rotating shaft 61 are rotatably connected to the feeding section 11. The rotating shaft 61 is fixedly connected to the rotor 6, which is located in the feeding section 11. Multiple circumferentially arranged blades are formed on the outer side of the rotor 6. The motor 7 is fixedly connected to the housing 1 and drives the rotating shaft 61 to rotate. The feeding speed is controlled by controlling the rotational speed of the rotor. The funnel 13 is fixedly connected to the material tower.
