Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, to the technical solution in the embodiment of the utility model into
Row clearly and completely describes, it is clear that and the described embodiments are only a part of the embodiments of the utility model, rather than all
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creative work premise
Lower all other embodiments obtained, shall fall within the protection scope of the present invention.
As Figure 1-Figure 2, a kind of feed device that feeding amount is adjusted by self-balancing of the utility model, including material
Bucket 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 hinged, and lower supporter 21 is fixedly mounted on the ground, which can be around
Hinge joint is freely rotated；Feed device 3 includes two roll shafts 31 and a conveyer belt 32, and a roll shaft 31 is installed on balance bracket
2 end, another roll shaft 31 are installed 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 fixing bracket
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 is contacted with the material mouth of 1 rear lower of hopper, the middle part of long connecting rod 42 and the side wall of hopper 1
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 hinged with balance bracket 2, and the hinge joint between short connecting rod 43 and balance bracket 2 is located at balance bracket 2 and lower supporter 21
Between hinge joint and balance weight mechanism 5.Its principle is：By making balance bracket 2 and the left and right sides of the hinge joint of lower supporter 21
Torque is equal, direction on the contrary, keep hopper door 41 folding size, realize the constant of conveying amount, if conveying amount changes so that
Balance bracket 2 and the change of the torque size on the right side of the hinge joint of lower supporter 21 are influenced, 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, direction conversely, because 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 hinge 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 hinge 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 hinge joint both sides is found out,
Reduce calculating.
If two roll shafts 31 are located at the side of lower supporter 21 and the hinge 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 stent 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 adjusting of own wt, can also proceed to bottom branch
The distance between hinge joint of frame 21 and balance bracket 2 is adjusted, its concrete structure is：Balance weight mechanism 5 includes 52 He of base
More weights 53, the straight-bar 54 of a vertical direction are 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 adjusting；Balance bracket
2 are provided with the sliding slot 22 along 2 length direction of balance bracket in the position of installation balance weight mechanism 5, and base 52 is relative to sliding slot 22
Position be provided with through hole 51, a bolt is pierced into through hole 51, and locked with nut, this is adjusted into row position
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, which can rotate around its shaft.
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 21 hinge joint of lower supporter, 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 the discharge port of material from 1 lower part of hopper drops at this time
On conveyer belt 32, under the movement of conveyer belt 32, material is brought to right side；
At this time, if the material from hopper 1 out is excessive, the torque on the left of torque ratio hinge joint on the right side of hinge joint
Big, balance bracket 2 is rotated clockwise along hinge joint at this time, while short connecting rod 43 moves up, driving long connecting rod 42 around
Hinge joint between hopper 1 rotates clockwise, so as to drive hopper door to move down, the discharge port of hopper 1 is reduced, so that
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 hinge joint on the left of hinge joint is big,
Balance bracket 2 is rotated counterclockwise along hinge joint at this time, while short connecting rod 43 moves down, driving long connecting rod 42 around with hopper
Hinge joint between 1 rotates counterclockwise, so as to drive hopper door to move up, the discharge port of hopper 1 is increased, so as to increase thing
The conveying capacity of material.
While there has been shown and described that the embodiment of the utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from the principle of the utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
