Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in embodiments of the invention is carried out it is clear,
It is fully described by, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.Base
Embodiment in the present invention, those of ordinary skill in the art obtained under the premise of creative work is not made it is all its
His embodiment, belongs to the scope of protection of the invention.
As Figure 1-Figure 2, a kind of feed device that feeding amount is adjusted by self-balancing of the invention, including hopper 1,
Balance bracket 2, feed device 3, hopper door open-and-close mechanism 4, balance weight mechanism 5.
Balance bracket 2 and lower supporter 21 are be hinged, and lower supporter 21 is fixedly mounted on the ground, and the balance bracket 2 can be around
Pin joint freely rotates；Feed device 3 includes two roll shafts 31 and a conveyer belt 32, and a roll shaft 31 is arranged on balance bracket
2 end, another roll shaft 31 are arranged on the middle part of balance bracket 2, and the set fastened on two roll shafts 31 is filled with
One conveyer belt 32, feed device 3 are driven by the motor on balance bracket 2.It is provided with the other end of balance bracket 2
Balance weight mechanism 5.
Hopper 1 is fixedly mounted on ground, and the conveyer belt of the sawing sheet mouth alignment feed device 3 of hopper 1 by fixed support
32, one striker plate 12 is installed at the back of hopper 1, to prevent the material from hopper 1 out from sliding to the left.Hopper door folding
The inner side of the hopper door 41 of mechanism 4 contacts with the material mouth of the rear lower of hopper 1, the middle part of long connecting rod 42 and the side wall of hopper 1
Be hinged, one end of long connecting rod 42 is fixedly connected with hopper door 41, and one end of the other end and short connecting rod 43 is hinged, short connecting rod 43 it is another
One end is be hinged with balance bracket 2, and the pin joint between short connecting rod 43 and balance bracket 2 is located at balance bracket 2 and lower supporter 21
Between pin joint and balance weight mechanism 5.Its principle is：By making balance bracket 2 and the left and right sides of the pin joint of lower supporter 21
Torque is equal, in opposite direction, keeps the folding size of hopper door 41, realizes the constant of conveying amount, if conveying amount changes, so as to
Balance bracket 2 and the change of the torque size on the right side of the pin joint of lower supporter 21 are influenceed, final result is to make opening for hopper door 41
Close size to change so that conveying, which measures, to be changed.
Lever principle is：Two torques acted on lever are equal in magnitude, in the opposite direction, due in the present embodiment,
The gravity of balance bracket 2 can not possibly ignore, and in order to reduce computing, improve the efficiency of adjustment balance weight mechanism 5, in the present embodiment
The pin joint of lower supporter 21 and balance bracket 2 be located at the position of centre of gravity of balance bracket 2, so in balance bracket 2 in pin joint
The moiety by weight of both sides is equal, and it is regular, it is easy to position of centre of gravity of the balance bracket 2 in pin joint both sides is found out,
Reduce calculating.
If two roll shafts 31 are located at the side of lower supporter 21 and the pin joint of balance bracket 2, so in balance weight mechanism 5
During selection, it is necessary to increase the weight of balance weight mechanism 5, in order to reduce the weight of balance weight mechanism 5, two roll shafts 31 are respectively positioned at flat
The both sides of the position of centre of gravity of weighing apparatus support 2.
Because the feed device is when in use, it is impossible to a kind of freight volume is only to maintain, so, balance weight mechanism 5 is necessary can
To be adjusted.In the present embodiment, balance weight mechanism 5 can not only carry out the regulation of own wt, can also proceed to bottom branch
The regulation of the distance between pin joint of frame 21 and balance bracket 2, its concrete structure are：Balance weight mechanism 5 includes a He of base 52
More weights 53, the straight-bar 54 of a vertical direction is provided with base 52, the top of the straight-bar 54 is provided with screw thread, weight 53
Middle part is provided with through hole, is through on straight-bar 54, this is the mechanism for carrying out balance weight mechanism own wt regulation；Balance bracket
2 are provided with the chute 22 along the length direction of balance bracket 2 in the position of installation balance weight mechanism 5, and base 52 is relative to chute 22
Position be provided with through hole 51, a bolt is pierced into through hole 51, and locked with nut, this is to carry out position adjustments
Mode.
Conveyer belt 32 is for a long time in use, relaxation, such conveyer belt 32 can be produced due to the ductility of own material
Slip can be produced between roll shaft 31, have impact on the efficiency of conveying, in order to ensure that conveyer belt 32 can be opened in time after relaxation
Tightly, a loosening and tightening wheel 34 is also installed on feed device 3, concrete structure is：The lower section of balance bracket 2 downwards with balance bracket 2
The vertical position of body is provided with a support 23, and fluting 24 is provided with support, is pacified on fluting 24 by bolt and nut
Loosening and tightening wheel 34 is filled, the loosening and tightening wheel 34 can be around its axis of rotation.
Operation principle：First first according to the speed of the material to be transmitted, calculate weight needed for balance weight mechanism 5, with
The distance of balance bracket 2 and the pin joint of lower supporter 21, the weight of adjustment balance weight mechanism 5 is realized by increasing and decreasing the quantity of weight 53
Amount；
Motor is opened, the roll shaft 31 of driving feed device 3 rotates, and now material drops from the discharging opening of the bottom of hopper 1
On conveyer belt 32, under the movement of conveyer belt 32, material is brought to right side；
Now, if the material from hopper 1 out is excessive, the torque on the left of torque ratio pin joint on the right side of pin joint
Big, now balance bracket 2 rotates clockwise along pin joint, while short connecting rod 43 moves up, driving long connecting rod 42 around
Pin joint between hopper 1 is rotated clockwise, and so as to drive hopper door to move down, the discharging opening of hopper 1 is reduced, so as to
Reduce the conveying capacity of material；
If the material from hopper 1 out is very few, the torque on the right side of torque ratio pin joint on the left of pin joint is big,
Now balance bracket 2 rotates counterclockwise along pin joint, while short connecting rod 43 moves down, driving long connecting rod 42 around with hopper
Pin joint between 1 rotates counterclockwise, and so as to drive hopper door to move up, the discharging opening of hopper 1 is increased, so as to increase thing
The conveying capacity of material.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of changes, modification can be carried out to these embodiments, replace without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
