Description
Technical field
The utility model relates to a kind of weighing utensil, especially relates to a kind of automatic weighing loading and unloading device.
Background technology
In vast rural area, daily necessitiess commonly used such as similar cereal crops such as many things such as flour, wheat, corn and granulated sugar, salt, alkali face will be leaned on manual weighing, loading and unloading when carrying out the short run packing or sporadicly buying and selling, waste time and energy at present.Though special-purpose automatic equipment is arranged on the market, cost an arm and a leg, be mainly used on the production line of producing bagged product, inapplicable for the rural area that income is lower.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, easy to use, cheap automatic weighing loading and unloading device.
For achieving the above object, the utility model can be taked following technical proposals:
Automatic weighing loading and unloading device described in the utility model, it comprises the platform balance body that is arranged on the bracing frame, and the scale pan of described platform balance body is provided with the cover body of upper opening, and discharge channel is obliquely installed in described cover body and extends outside the cover body; Be hinged with a U-shaped batch box in the upper end of described discharge channel, its upper shed was corresponding with the discharging opening of the feeding hopper that is arranged on the support frame as described above top when described U-shaped batch box was upright; The sidewall of cover body is provided with motor and thrust spring; Be wound with two stay cords on the motor shaft of described motor, the other end of described two stay cords is connected with the elasticity bin gate at U-shaped batch box, feeding hopper discharging opening place respectively; Lateral wall when the other end of described thrust spring is upright with the U-shaped batch box contacts; Bracing frame is provided with switch; Below the sliding weight of steelyard of platform balance body, be provided with electric contact with described sliding weight of steelyard opening and closing.
Described stay cord is an elastic drag rope.
Corresponding position at U-shaped batch box and discharge channel is provided with adhesive tape.
Advantage of the present utility model is when needs weighing article, connect between the electric contact by the switch on the bracing frame and sliding weight of steelyard and sliding weight of steelyard below, constitute the loop, drive motor rotates, and drives the unlatching of the upright and feeding hopper discharging opening of U-shaped batch box simultaneously, in the article impouring U-shaped batch box of splendid attire in feeding hopper, after the article in the U-shaped batch box reach the weight that needs weighing on the platform balance rule, lift on the sliding weight of steelyard, with the electric contact disengaging of sliding weight of steelyard below, motor stall; The U-shaped batch box tilts along discharge channel, and article are poured out and are collected along discharge channel in it, thereby realizes the purpose of automatic weighing.Process is simple and reliable, weighing is accurate, and with low cost, is specially adapted to the rural area.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, automatic weighing loading and unloading device described in the utility model, it comprises the platform balance body that is arranged on the bracing frame 1, and the scale pan 2 of described platform balance body is provided with the cover body 3 of upper opening, and discharge channel 4 is obliquely installed in described cover body 3 and extends outside the cover body 3; Be hinged with a U-shaped batch box 5 in the upper end of described discharge channel 4, its upper shed was corresponding with the discharging opening of the feeding hopper 6 that is arranged on bracing frame 1 top when described U-shaped batch box 5 was upright; The sidewall of cover body 3 is provided with motor 7 and thrust spring 8; Be wound with two stay cords 9,10 on the motor shaft of described motor 7, the other end of described two stay cords 9,10 is connected with the elasticity bin gate 11 at U-shaped batch box 5, feeding hopper 6 discharging opening places respectively; Lateral wall when the other end of described thrust spring 8 and U-shaped batch box 5 are upright contacts; Bracing frame 1 is provided with switch 12,13; Below the sliding weight of steelyard 14 of platform balance body, be provided with electric contact 15 with described sliding weight of steelyard 14 opening and closing.
For guaranteeing safety, this device can select to be lower than 40 volts safe voltage.When not working, U-shaped batch box 5 tilts to place along discharge channel 4.When the needs weighing, rule is allocated to and need locates the weighing location, at this moment sliding weight of steelyard 14 contacts with the electric contact 15 of its below, operating switch 12 and contact 18 conductings, operating switch 13 and contact 16 conductings, motor 7 energisings drive U-shaped batch box 5 and rise to stand up position, elasticity bin gate 11 is opened simultaneously, and material flows out.After the article in the U-shaped batch box 5 reach the weight that needs weighing on the platform balance rule, lift on the sliding weight of steelyard 14, with electric contact 15 disengagings of sliding weight of steelyard 14 belows, motor 7 stalls; U-shaped batch box 5 tilts along discharge channel 4, and toggle switch 13 disconnects with contact 16, and article are poured out and are collected along discharge channel 4 in it, finish disposable loading and unloading.
For making things convenient for the short run weighing, this device also can be realized continuous action: operating switch 12 and contact 19 conductings, operating switch 13 and contact 17 conductings, rely on the break-make between sliding weight of steelyard 14 and the electric contact 15 below it, the action of beginning continuity is pulled with contact 19 disconnections and can be stopped until switch 12.For guaranteeing that U-shaped batch box 5 has time enough to unsnatch material, stay cord 9 can be arranged to elastic drag rope, in the corresponding position of U-shaped batch box and discharge channel adhesive tape is set.
