Abstract
The utility model discloses a sand hopper with an automatic opening-closing device, wherein a discharge hole (4) of the sand hopper (3) is provided with an automatic opening-closing device; the automatic opening-closing device comprises a cross bar (6), a supporting rod (2) fixedly connected at the side surface of the discharge hole (4), and a baffle (5) and a balance weight (1) which are used for blocking the discharge hole (4); the cross bar (6) and the baffle (5) are fixedly connected; the cross bar (6) is movably connected at the lower end of the supporting rod (2); and the balance weight (1) is movably connected on the cross bar (6) to lead the balance weight (1) to drop by gravity so as to lead the baffle to block the discharge hole (4). The sand hopper with the automatic opening-closing device has high reliability and does not generate blocking phenomenon.
Description
Technical field
The utility model relates to the sand hopper of charging, especially the drawing mechanism of sand hopper.
Background technology
Sand hopper is widely used on the industrial production.Sand hopper is mainly used to loaded material and passes through discharge hole for discharge.Sand hopper commonly used is provided with opening and closing device at discharging opening, by the motor-driven opening and closing device, reaches the purpose of discharging on request.The shortcoming of above-mentioned opening and closing device is a complex structure, in when operation, by motor-driven, often owing to when bigger material piece occurring, can produce stuck phenomenon, easily burns motor, and reliability is low, can cause very big influence to production.
The utility model content
The purpose of this utility model is exactly to solve the easily stuck problem of existing sand hopper opening and closing device, and a kind of sand hopper with automatic switch device is provided.
The technical solution adopted in the utility model is: the sand hopper of band automatic switch device, it is characterized in that it is that discharging opening at sand hopper is provided with automatic switch device, described automatic switch device comprises cross bar, be fixed in the support bar of discharging opening side and be used for sealing the baffle plate and the balance weight of discharging opening, cross bar and baffle plate are fixed together, cross bar is movably connected in the support bar lower end, balance weight is movably connected on the cross bar, makes balance weight make baffle plate seal discharging opening because of gravity descends.
Adopt technique scheme, discharging opening is closed during moment that the moment that produces in sand hopper material amount lower weight produces less than balance weight, during moment that the moment of giving birth to when sand hopper material volume production produces greater than balance weight, material will overcome the moment that balance weight produces, the baffle plate upset is opened, and material spills from discharging opening.
The beneficial effects of the utility model are: the utility model parts are few, and are simple in structure, so use cost is low; The utility model does not have drive unit simultaneously, therefore can not produce stuck phenomenon, and good reliability has effectively guaranteed the normal operation of producing.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Among the figure, 1, balance weight, 2, support bar, 3, sand hopper, 4, discharging opening, 5, baffle plate, 6, cross bar.
The specific embodiment
The sand hopper of the utility model band automatic switch device, as shown in Figure 1, it is that discharging opening 4 at sand hopper 3 is provided with automatic switch device, described automatic switch device comprises cross bar 6, be fixed in the support bar 2 of discharging opening 4 sides and be used for sealing the baffle plate 5 and the balance weight 1 of discharging opening 4, cross bar 6 is fixed together with baffle plate 5, cross bar 6 is movably connected in support bar 2 lower ends, and balance weight 1 is movably connected on the cross bar 6, makes balance weight 1 make baffle plate seal discharging opening 4 because of gravity descends.
Adjust for convenient, can between cross bar 6 and balance weight 1, be provided with positioner, make balance weight 1 on cross bar 6, to locate the optional position, thereby can make according to actual needs, adjust the position of balance weight 1.
Claims (1)
1. be with the sand hopper of automatic switch device, it is characterized in that it is that discharging opening (4) in sand hopper (3) is provided with automatic switch device, described automatic switch device comprises cross bar (6), is fixed in the support bar (2) of discharging opening (4) side and is used for sealing the baffle plate (5) and the balance weight (1) of discharging opening (4), cross bar (6) is fixed together with baffle plate (5), cross bar (6) is movably connected in support bar (2) lower end, balance weight (1) is movably connected on the cross bar (6), makes balance weight (1) make baffle plate seal discharging opening (4) because of gravity descends.
