Description

Technical Field

[0001] The utility model relates to the technical field of grain conveying machinery, in particular to a discharger. Background Art

[0002] After the bulk grain is unloaded from the truck bed, it needs to be transported to the production equipment or piled up by a belt unloader.

[0003] After unloading, the grains are first fed into the feed hopper, and then the grains fall from the outlet at the bottom of the feed hopper onto the belt conveyor, and then are sent to the production equipment or piled up through the belt conveyor. After the grains fall onto the belt conveyor, they will form a hill shape with a high middle and low sides, which makes the distribution of the grains on the belt of the belt conveyor very uneven, causing the middle of the belt conveyor to be subjected to greater force and less force near the edge, thus causing uneven wear of the belt of the belt conveyor, causing the middle of the belt to be damaged prematurely due to wear, thereby shortening the service life of the belt.

[0029] Example 1

[0030] like Figures 1 to 4 As shown, a discharge machine includes a first frame 2, a horizontal first belt conveyor 4 fixedly arranged on the first frame 2, a feed hopper 3 arranged above the first belt conveyor 4 and fixedly connected to the first frame 2, a second frame 8 arranged on the right side of the first frame 2, and a second belt conveyor 5 fixedly arranged on the second frame 8 and inclined from the lower left to the upper right. The first frame 2 and the second frame 8 are both welded from profiles, and a paddle 1 is provided on the outer surface of the belt of the second belt conveyor 5 to prevent materials from sliding downward along the belt surface of the second belt conveyor 5.

[0031] The lower left feed end of the second belt conveyor 5 corresponds to the right discharge end of the first belt conveyor 4; a herringbone dividing plate 6 is provided in the discharge port 7 at the bottom of the feed hopper 3, and the dividing plate 6 is in a long strip shape, and the conveying direction of the dividing plate 6 is consistent with that of the belt conveyor. In actual production, the dividing plate 6 can be made of angle steel. The two ends of the dividing plate 6 are respectively fixedly connected to the inner side of the feed hopper 3, and there is a gap between the two sides of the dividing plate 6 and the inner wall corresponding to the feed hopper 3. The dividing plate 6 separates the discharge port 7, and after the material is added to the feed hopper 3, it falls downward from the gaps on both sides of the dividing plate 6 onto the first belt conveyor 4.

[0032] Combination Figure 7 and Figure 8 As shown, Figure 7 This is a schematic diagram of materials being piled up on the belt of the first belt conveyor 4 when the material dividing plate 6 is not provided. Figure 8 It is a schematic diagram of the material being piled up on the belt of the first belt conveyor 4 after the material dividing plate 6 is set. It can be seen that after the material dividing plate 6 is set, the material is piled up more evenly on the first belt conveyor 4, so that the belt of the first belt conveyor 4 is more evenly stressed, preventing the belt from being accelerated to wear due to excessive stress locally, thereby extending the service life of the first belt conveyor 4.

[0033] Example 2

[0034] like Figure 5 and Figure 6 As shown, the difference between this embodiment and embodiment 1 is that:

[0035] The material dividing plate 6 includes a first baffle plate 9 and a second baffle plate 10 which are symmetrically arranged, and the first baffle plate 9 and the second baffle plate 10 form a herringbone shape. A rotating shaft 13 is arranged in the feed hopper 3, and both ends of the rotating shaft 13 are respectively fixedly connected to the feed hopper 3. The top of the first baffle plate 9 and the top of the second baffle plate 10 are both rotatably connected to the rotating shaft 13, and a driving mechanism for opening or closing the first baffle plate 9 and the second baffle plate 10 is arranged on the feed hopper 3.

[0036] The driving mechanism includes a linear slide 14 arranged below the first baffle 9 and the second baffle 10. The linear slide 14 is parallel to the rotating shaft 13. Both ends of the slide seat of the linear slide 14 are fixedly connected to the feed hopper 3. Connecting rods 12 are respectively arranged on both sides of the slider 17 of the linear slide 14. The two connecting rods 12 are symmetrically arranged on both sides of the slider 17. The ends of the connecting rods 12 away from the slider 17 are respectively connected to the corresponding first baffle 9 or second baffle 10. Each connecting rod 12 intersects with the axis space of the rotating shaft 13. The connecting rods 12 connected to the first baffle 9 are parallel to each other, and the connecting rods 12 connected to the second baffle 10 are parallel to each other. Universal ball joints 11 are arranged between the slider 17 of the linear slide 14 and the connecting rod 12, between the first baffle 9 and the connecting rod 12, and between the second baffle 10 and the connecting rod 12.

[0037] The linear slide 14 is provided with two slider groups with opposite moving directions, each slider group has at least one slider 17, and the sliders 17 of the two slider groups move in opposite directions. The connecting rods 12 corresponding to the same slider group and located on the same side of the linear slide 14 are parallel to each other, and the connecting rods 12 corresponding to the two slider groups and located on the same side of the linear slide 14 are in opposite directions.

[0038] When the sliders 17 in the two slider groups move in the opposite direction, the corresponding ends of the connecting rods 12 move in the opposite direction, thereby driving the first baffle 9 and the second baffle 10 to open or close, so that the areas of the two discharge ports 7 separated by the first baffle 9 and the second baffle 10 can be adjusted, and then the flow rate of the material falling from the feed hopper 3 to the first belt conveyor 4 can be adjusted. This is particularly suitable for conveying grains of different particle sizes. By adjusting the area of ​​the discharge port 7, the material can be ensured to fall smoothly, and the material can be prevented from accumulating in large quantities on the first belt conveyor 4 and causing blockage.

[0039] The two sets of slider groups have the same number of connecting rods 12, so that the forces acting on the first baffle plate 9 and the second baffle plate 10 in the axial direction of the rotating shaft 13 can offset each other, thereby making the first baffle plate 9 and the second baffle plate 10 swing more smoothly.

[0040] Since the linear slide 14 , the universal ball joint 11 and the connecting rod 12 are all arranged under the first baffle 9 and the second baffle 10 , it is possible to prevent materials from entering the linear slide 14 and affecting the operation of the linear slide 14 .

[0041] Example 3

[0042] The linear slide 14 is a screw linear slide, and the screw 15 of the screw linear slide has a thread direction opposite to that of the parts corresponding to the two slider groups.

[0043] One end of the lead screw 15 is fitted with a gap through the feed hopper 3, and the lead screw 15 is provided with a hand wheel 16 at the end. The hand wheel 16 is turned to drive the lead screw 15 to rotate, and then the first baffle 9 and the second baffle 10 are driven to swing through the connecting rod 12, so as to adjust the opening and closing angles of the first baffle 9 and the second baffle 10, so as to adjust the area of ​​the discharge port 7. After the hand wheel 16 stops turning, the positions of the first baffle 9 and the second baffle 10 can be locked by the self-locking function of the lead screw 15.
