Abstract

The utility model discloses a multiple belt combined feeder for the conveying of various materials, comprising a driving mechanism, a machine frame, a carrying roller, a feed apparatus and a material guide apparatus. The barrels on the two sides of the machine frame are provided with concave grooves for preventing the conveyor belt from deviating, or the lower part of the barrel is provided with spacing grooves for preventing the conveyor belt from deviating. The conveyor belt is corresponding to the concave groove on the barrel or the spacing grooves in the lower part of the barrel are matched with conveyor belts with different structures. The multiple belt combined feeder has the advantages of reasonable structure, easy production, convenient operation and maintenance. The conveyor belt runs with no deviation, small operation resistance, low power consumption, and high power factor. Besides, the conveyor belt is an elastic body, which can relax the impact of the materials and absorb the vibration, so the transmission is stable and the noise is few. The utility model has no environmental limitation, which can be used in hostile environment such as the underground with high firedamp, high dust, low temperature, high dampness, etc. The multiple belt combined feeder of the utility model can convey the hard and sharp materials such as iron ware, and the materials with a temperature less than 200 degree, which brings long service life and extensive practicability.

Description

Multiple belt combination feeder

One, technical field

The utility model relates to multiple belt combination feeder, is particularly useful for the conveying of coal, ore, also is applicable to the conveying of various materials.

Two, background technology

Being used for feeding device under the storehouse at present has multiplely, mainly contains reciprocating feeder, oscillating feeder, chain type feeding machine.The reciprocating feeder base plate needs to bear the very big friction force of material in backhaul, so power consumption is big, vibration is big, and feed is discontinuous, and productive capacity is low, and the movement parts wearing and tearing are big, and maintenance capacity is also big; Oscillating feeder is owing to be by higher frequency and amplitude vibration feed, amplitude and frequency are subjected to the granularity of material and density to influence bigger, so cause the feeding coal instability, the adjustment of feeding coal is difficulty relatively, be difficult to control when particularly needing to stop feeding coal immediately, the noise that vibration is produced is big, and base plate can not bear than material in the storehouse of big pressure; Therefore the chain type feeding machine is far from suitable to bulk materials and foreign material owing to be carrier bar and chain gear feed, particularly runs into ironware and timber and easily causes chain rupture, disconnected plate accident.Another crawler type feeder is because no anti-deflection device, only keeping off anti-partially by the metal on load-transfer device both sides and polyester plate, and adhesive tape and metal tape serious wear are added between adhesive tape in its load-transfer device and the metal tape and easily entered material, cause faults such as sideslip.

Three, technology contents

1. goal of the invention

In view of the deficiency that prior art exists, the purpose of this utility model provides a kind of simple in structure, and is low in energy consumption, and feed is continuous, sideslip not, long service life, effective multiple belt combination feeder.

2. technical scheme

The multiple belt combination of the utility model feeder, it comprises transmission device, the carrying roller that is provided with on frame and the frame; Ride over feed arrangement and material guide device on the frame, can offer the groove that prevents belt deflection on the cylinder that the frame both sides are provided with, or the position-limited trough that prevents belt deflection is set, the load-transfer device of the position-limited trough coupling different structure of the groove on the load-transfer device respective rollers or its below below cylinder.

The multiple belt combination of the utility model feeder, the position-limited trough that groove on the cylinder or cylinder below are provided with is symmetrical arranged.It can be trapezoidal stating the groove that symmetry is offered on the cylinder, also can be circular arc, can also be rectangle.Load-transfer device can be that caoutchous is made, and also can be that rubber and hard ware are synthetic.Load-transfer device following or above be provided with the boss of respective rollers groove or position-limited trough.With rubber and the synthetic load-transfer device of hard ware, its hard ware is spaced agent and is pressed in the rubber tape

3. technique effect

The multiple belt combination of the utility model feeder, be best suited for the conveying of coal, ore, on the cylinder of frame both sides setting, offer the groove that prevents belt deflection, or the position-limited trough that prevents belt deflection is set, the load-transfer device of the position-limited trough coupling different structure of the groove on the load-transfer device respective rollers or its below below cylinder.Compared with prior art, load-transfer device is sideslip not, and is rational in infrastructure, is easy to make, and is convenient to operation and maintenance; Its running resistance is little, and is low in energy consumption, the power factor height; Load-transfer device is an elastic body, can relax the impact of material, absorbs vibration, stable drive, and noise is little; Be not subjected to environmental restraint, under harsies environment such as the high gas in down-hole, high dust low temperature and moisture, can use; Can carry such as the hard sharp material of ironware, the material of right＜200 ℃ also can be carried, and long service life has practicality widely.

Five, body embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described:

The multiple belt combination of the utility model feeder, as shown in Figure 1, it comprises transmission device, the carrying roller 6 that is provided with on frame 1 and the frame 1; Ride over feed arrangement 3 and material guide device 7 on the frame 1, frame 1 is provided with cylinder 2 and load-bearing cylinder 4 end to end, can offer the groove that prevents load-transfer device 5 sideslips on the cylinder 2, or the position-limited trough 8 that prevents load-transfer device 5 sideslips is set below cylinder 2, the load-transfer device 5 of the position-limited trough 8 coupling different structures of the groove on load-transfer device 5 respective rollers 2 or its below, the position-limited trough that groove on the cylinder 2 or cylinder 2 belows are provided with is symmetrical arranged.Load-transfer device 5 is as follows with cylinder 2 specific embodiments:
