DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The following provides a ore chute having a unique ore storage mechanism, which can accumulate a layer of ore on the surface of the chute to replace the wear-resistant auxiliary plate, transfer the wear caused by the falling ore to the ore itself, so as to increase the service life of the chute.

[0028] Combination Figure 1 , the lower chute includes:

[0029] The tank body 1 comprises a bottom wall 11 and side walls 12 erected on both sides of the bottom wall 11, and is used to guide the ore to flow downward between the bottom wall 11 and the side walls 12;

[0030] The baffle bars 2 are erected on the bottom wall 11 of the trough body 1 and extend along the width direction of the trough body 1 to the two side walls 12 of the trough body 1. When the number of baffle bars is greater than one, they are arranged side by side along the length direction of the trough body 1 to form an ore storage area (3) for accumulating ore between the bottom wall 11 of the trough body 1 and the two side walls 12.

[0031] When the bottom wall 11 of the trough body 1 is at an inclined angle relative to the horizontal plane, the trough body 1 can be used to transport ore. The ore flows along the bottom wall 11 of the trough body 1 under the action of gravity. A part of the ore is blocked by the baffle 2 and stays in the ore storage area (3) formed between two adjacent baffles 2. The stopped ore forms a wear-resistant layer with a longitudinal section of a triangle or a body, which is used to protect the bottom wall 11 of the trough body 1 from being worn by the flowing ore.

[0032] Optionally, the width of the trough body 1 is 60 cm, the height of the side wall 12 of the trough body 1 is 30 cm, the length of the trough body 1 is 2 m, the height of the baffle is 8 cm, the thickness of the baffle is 2 cm, and the distance between adjacent baffles 2 is 30 cm.

[0033] The baffle 2 can be directly welded to the bottom wall 11 of the tank body 1, but welding the two has obvious defects. Figure 3 and Figure 4 The greater the inclination angle of the trough body 1, the higher the height of the wear-resistant layer, and the easier it is for the ore accumulated inside the ore storage area (3) to collapse under the impact of the flowing ore, resulting in the bottom wall 11 of the trough body 1, which is located between two adjacent baffles 2 and is higher, not being covered by the ore and lacking the protection of the wear-resistant layer.

[0034] In order to solve the above problem, the greater the inclination angle of the trough body 1, the more baffles 2 are needed, and the distance between two adjacent baffles 2 is reduced so that the height difference between two adjacent baffles 2 is less than the maximum height of the wear-resistant layer, so that the bottom wall 11 of the trough body 1 is always protected by the ore. However, the more baffles 2 there are, the more baffles 2 will be worn synchronously, thereby increasing the maintenance cost of the trough body 1.

[0035] Therefore, preferably, the baffle 2 is detachably connected to the bottom wall 11 of the trough body 1. This design allows the staff to select the appropriate number of baffles 2 according to the unloading angle of the trough body 1, so as not to cause wear of the bottom wall 11 of the trough body 1 or excessive wear of the baffles 2.

[0036] Combination Figure 3 and Figure 5 The trough body 1 is covered with a plurality of through holes 13, and an anchor bolt 14 is inserted into each of the through holes 13. The anchor bolts 14 are located on both sides of the trough body 1 and are fully welded to the trough body 1. The anchor bolts 14 are mushroom-shaped, and have a cylindrical portion 141 inserted into the through hole 13 and a disc portion 142 located outside the through hole 13. A gap is left between the disc portion 142 and the bottom wall 11 of the trough body 1. The baffle 2 is made of angle steel, and the baffle 2 includes an insert plate 21 inserted between the bottom wall 11 of the trough body 1 and the disc portion 142. An opening 211 that matches the cylindrical portion 141 is formed on one side of the insert plate 21. The baffle 2 also includes a baffle plate 22 that is perpendicular to the insert plate 21 and stands upright on the bottom wall 11 of the trough body 1.

[0037] After the plug plate 21 is plugged into the anchor bolt 14, the baffle plate 22 is located above the plug plate 21. This design makes the connection between the plug plate 21 and the anchor bolt 14 more secure when the baffle plate 22 is impacted by ore. The anchor bolt 14 not connected to the baffle bar 2 is covered by the ore and is not impacted or worn by the ore.

[0038] After cleaning the ore on the tank body 1, the blocking bar 2 can be separated from the tank body 1 by lifting it upward along the bottom wall 11 of the tank body 1, and vice versa, the blocking bar 2 can be installed.

[0039] Furthermore, since the tank body 1 and the baffle 2 are light in weight, they are prone to vibration, displacement and overturning when transporting dense ore. In order to solve this problem, Figure 3 , Figure 4 and Figure 5 The lower ore chute also includes: a counterweight 4, which is fixedly connected to the bottom of the chute body 1.

[0040] Optionally, the counterweight 4 includes a square box 41, the top of the square box 41 is fitted with the bottom of the trough body 1 and fully welded, the square box 41 is a hollow box with a length of 2m, a width of 60cm, a height of 10cm and a thickness of 1cm, a 5cm grouting hole is reserved on one side of the square body, and concrete 42 is poured inside. Other solidifiable slurries besides concrete 42 may also be used, as long as they can improve the plasticity of the square box 41 and increase its weight.

[0041] Furthermore, combined with Figure 3 and Figure 4 .

[0042] A hook 43 is provided at one end of the counterweight 4. The hook 43 is used to hook and fix the building when the tank body 1 is tilted, so that the position of one end of the tank body 1 is constrained.

[0043] A support leg 5 is provided at the other end of the counterweight 4, and the support leg 5 is rotatably connected to the counterweight 4. The rotation axis 52 of the support leg 5 is horizontally arranged, and the bottom of the support leg 5 is provided with anti-slip grooves 51. The support leg 5 is used to support the counterweight 4 to prevent the end of the counterweight 4 from being worn.

[0044] A bracket 44 is provided at one end of the counterweight 4 connected to the support leg 5, and an axial hole 45 is provided on the bracket 44. The support leg 5 is fixedly connected to a rotating shaft 52, and the rotating shaft 52 is inserted into the inside of the axial hole 45. The diameter of the axial hole 45 is larger than the diameter of the rotating shaft 52, so that the rotating shaft 52 can move radially a certain distance inside the axial hole 45.

[0045] The bracket 44 is provided with an arc-shaped arc-shaped through hole 46, which takes the shaft hole 45 as the center, and a plurality of side-by-side grooves 47 are formed on the side of the arc-shaped through hole 46 facing the shaft hole 45. The support leg 5 is fixedly connected with a load-bearing rod 53, which is inserted into the interior of the arc-shaped through hole 46 and can slide inside the arc-shaped through hole 46, and the load-bearing rod 53 can be engaged with any one of the grooves 47.

[0046] Combination Figure 4 When the support leg 5 is not in contact with the ground, the load-bearing rod 53 can move inside the arc-shaped through hole 46. After the support leg 5 contacts the ground and the weight of the counterweight 4 is transferred to the support leg 5, the load-bearing rod 53 engages with the groove 47 directly above it, so that the relative angle between the load-bearing rod 53 and the rotating shaft 52 is locked, thereby locking the relative angle between the support leg 5 and the bracket 44, so that the support leg 5 can be more firmly seated on the ground.
