As shown in fig. 1 to 3 and 9, a push type formwork discharging device for engineering road construction comprises a feeding mechanism 1, a blanking box 2, a horizontal bidirectional pushing mechanism 3, an elastic supporting mechanism 4 and a longitudinal feeding mechanism 5;
the feeding mechanism 1 is mounted on the mobile equipment and used for supplementing templates to the lower material box 2;
the blanking box 2 is mounted on the mobile equipment, and the feeding end of the blanking box is connected with the discharging end of the feeding mechanism 1 and used for blanking the template;
the horizontal bidirectional pushing mechanism 3 is arranged on the blanking box 2, is provided with a pair of working ends arranged towards the two sides of the blanking box 2 and is used for pushing the templates on the blanking box 2 to the discharging ends at the two sides;
the elastic supporting mechanisms 4 are arranged on two sides of the blanking box 2, are blocked on the discharging end of the blanking box 2 in a non-working state and are used for installing the longitudinal feeding mechanism 5;
and the longitudinal feeding mechanism 5 is arranged on the movable end of the elastic supporting mechanism 4, faces the central position of the blanking box 2 and is used for vertically and downwards sending the template out from the discharging end of the blanking box 2 at a constant speed.
The feeding mechanism 1, the horizontal bidirectional pushing mechanism 3, the elastic supporting mechanism 4 and the longitudinal feeding mechanism 5 are all electrically connected with the controller. The mobile equipment is an engineering vehicle. A plurality of groups of templates are firstly hoisted to the feeding mechanism 1 and the blanking box 2 by workers. The device is moved by the engineering vehicle during working. The controller sends signals to the horizontal bidirectional pushing mechanism 3, and after the horizontal bidirectional pushing mechanism 3 receives the signals, one pair of working ends of the horizontal bidirectional pushing mechanism 3 respectively pushes the two groups of templates to the longitudinal feeding mechanisms 5 at the two sides. The outermost formwork abuts against the working end of the longitudinal feed mechanism 5. The longitudinal feeding mechanism 5 retreats to two sides along with the movable end of the elastic supporting mechanism 4 after being pressed, thereby avoiding the blocked discharging end of the blanking box 2. When the template on the outermost side moves to the upper part of the discharge end of the blanking box 2, the two sides of the template are respectively and tightly propped against the template on the inner side and the working end of the longitudinal feeding mechanism 5. The controller sends a signal to the longitudinal feeding mechanism 5, and the longitudinal feeding mechanism 5 drives the template on the outermost side of the blanking box 2 to vertically and downwards penetrate through the discharging end of the blanking box 2 to fall at a constant speed after receiving the signal. When one template on the outermost side falls down, the longitudinal feeding mechanism 5 abuts against the template on the outermost side which is currently left on the blanking box 2 under the elastic support of the elastic supporting mechanism 4, and the previous process is repeated to finish blanking one by one for two groups of templates preinstalled on the blanking box 2. After the templates on the blanking box 2 are completely blanked. The controller sends a signal to the feeding mechanism 1, the feeding mechanism 1 supplements new two groups of templates into the blanking box 2 after receiving the signal, and then repeats the blanking operation steps on the blanking box 2 until all the template groups on the feeding mechanism 1 finish blanking through the blanking box 2.
As shown in fig. 4, the feeding mechanism 1 includes a feeding frame 1a, a first material guiding chute 1b, a second material guiding chute 1c, a first sliding chute 1d, a first material pushing plate 1e and a first linear driving assembly 1 f;

Workers firstly hoist a plurality of groups of templates in the first material guide groove 1b and the second material guide groove 1c, and the end surfaces of the templates are parallel to the moving direction of the templates in the first material guide groove 1b and the second material guide groove 1 c. After the two groups of templates on the two sides in the blanking box 2 are completely blanked, the controller sends a signal to the first linear driving assembly 1f, and the first linear driving assembly 1f drives the pair of first material pushing plates 1e to synchronously move towards the blanking box 2 in the first material guide groove 1b and the second material guide groove 1c respectively through the working end of the first linear driving assembly after receiving the signal, so that the plurality of groups of templates in the first material guide groove 1b and the second material guide groove 1c are simultaneously pushed towards the blanking box 2, and the feeding of the template group at the foremost end into the blanking box 2 is completed again.

a second supporting plate 4a vertically installed at one side of the discharging box 2;
a movable plate 4b movably installed at an inner side of the second supporting plate 4a in a horizontal direction for installing the longitudinal feeding mechanism 5;
a plurality of guide posts 4c, which are uniformly and vertically installed on one side of the movable plate 4b facing the second support plate 4a, are in clearance fit with the second support plate 4a, and are used for guiding and limiting the movement direction of the movable plate 4 b;

and a contact switch 4e installed on one side of the second supporting plate 4a facing the movable plate 4b for triggering the operation of the longitudinal feeding mechanism 5.
The contact switch 4e is electrically connected to the controller. The spring 4d provides elastic support to stop the longitudinal feeding mechanism 5 on the blanking groove 2c of the blanking box 2 in the non-working state. When the template abuts against the inner side of the longitudinal feeding mechanism 5, the longitudinal feeding mechanism 5 is pushed to move towards the direction of the second supporting plate 4a, so that the pushing movable plate 4b moves towards the direction of the second supporting plate 4a along the axial direction of the guide post 4c, and the longitudinal feeding mechanism 5 is driven to open the blanking groove 2c of the blanking box 2. The springs 4d also cause the working end of the longitudinal feed mechanism 5 to have a force directed towards the die plate, thereby clamping the outer end face of the die plate. When the movable plate 4b touches the contact switch 4e, it means that the template is located just above the blanking slot 2c of the blanking box 2. The contact switch 4e sends a signal to the controller, and the controller immediately sends a signal to the longitudinal feeding mechanism 5 after receiving the signal so as to start the longitudinal feeding mechanism 5. The movable plate 4b is a movable end of the elastic support mechanism 4.
As shown in fig. 8 and 10, the longitudinal feeding mechanism 5 includes a mounting frame 5a, a driving roller 5b, a driven roller 5c, a third rotary driver 5d, a conveyor belt 5e, and a pressure detecting assembly 5 f;

the third rotary driver 5d is arranged on the mounting frame 5a, and an output shaft is fixedly connected with one end of the driving roller 5b and used for driving the driving roller 5b to rotate;
the conveying belt 5e is in transmission connection with the driving roller 5b and the driven roller 5c and used for abutting against the template and blanking the template at a constant speed;
and the pressure detection assembly 5f is arranged on the inner side of the conveyor belt 5e, the two sides of the pressure detection assembly are fixedly connected with the two sides of the mounting frame 5a, and the working end of the pressure detection assembly abuts against the inner position of one side, in contact with the template, of the conveyor belt 5 e.
The third rotary driver 5d and the pressure detection assembly 5f are electrically connected to the controller. When the outermost template on the lower bin 2 abuts the conveyor belt 5e, the conveyor belt 5e transmits pressure to the pressure sensing assembly 5f inside it. The pressure detection assembly 5f sends a signal to the controller, and the controller adjusts the driving speed of the working end of the horizontal bidirectional pushing mechanism 3 according to the pressure received by the pressure detection assembly 5f so as to ensure that the conveyor belt 5e can provide stable clamping effect for the template. When the die plate moves above the blanking slot 2c of the blanking box 2. The controller sends a signal to the third rotary driver 5d, the third rotary driver 5d drives the driving roller 5b to rotate after receiving the signal, the driving roller 5b and the driven roller 5c are matched together to drive the conveying belt 5e to rotate, and the template is conveyed downwards from the blanking groove 2c of the blanking box 2 at a constant speed. The end face of the conveyor belt 5e is provided with a texture, not shown, for increasing the longitudinal friction.
As shown in fig. 10, the pressure detecting unit 5f includes a mounting plate 5f1 and an electronic scale 5f 2;
the mounting plate 5f1 is arranged on the inner side of the conveyor belt 5e, and two sides of the mounting plate are respectively fixedly connected with two sides of the mounting frame 5a to mount the electronic scale 5f 2;
and the electronic scale 5f2 is arranged at one end of the mounting plate 5f1 facing the inner side of the lower feed box 2, and the working end of the electronic scale is abutted against the inner side of the conveyor belt 5e so as to detect the acting force applied to the conveyor belt 5e from the template.
The electronic scale 5f2 is electrically connected to the controller. Mounting plate 5f1 provides support for electronic scale 5f 2. When the template moves towards the two sides of the blanking box 2, the template is abutted to the conveyor belt 5e, the conveyor belt 5e transmits the pressure to the electronic scale 5f2, the electronic scale 5f2 sends a signal to the controller, and the controller adjusts the driving speed of the horizontal bidirectional pushing mechanism 3 according to the signal so as to ensure that the conveyor belt 5e can be abutted to the outer side of the template.
The working principle of the invention is as follows:
the device realizes the functions of the invention through the following steps, thereby solving the technical problems provided by the invention:
firstly, a plurality of groups of templates are hoisted to a feeding mechanism 1 and a blanking box 2 by workers.
And step two, moving the device through the engineering vehicle during working.
And step three, the controller sends signals to the horizontal bidirectional pushing mechanism 3, and after the horizontal bidirectional pushing mechanism 3 receives the signals, one pair of working ends of the horizontal bidirectional pushing mechanism 3 respectively pushes the two groups of templates to the directions of the longitudinal feeding mechanisms 5 on the two sides.
And step four, the template at the outermost side is abutted against the working end of the longitudinal feeding mechanism 5. The longitudinal feeding mechanism 5 retreats to two sides along with the movable end of the elastic supporting mechanism 4 after being pressed, thereby avoiding the blocked discharging end of the blanking box 2.
And step five, when the template on the outermost side moves to the position above the discharge end of the blanking box 2, the two sides of the template are respectively abutted by the template on the inner side and the working end of the longitudinal feeding mechanism 5.
And step six, the controller sends a signal to the longitudinal feeding mechanism 5, and the longitudinal feeding mechanism 5 drives the template on the outermost side of the blanking box 2 to vertically and downwards penetrate through the discharging end of the blanking box 2 to fall at a constant speed after receiving the signal.
And seventhly, after one template on the outermost side falls down, the longitudinal feeding mechanism 5 abuts against the template on the outermost side left on the blanking box 2 under the elastic support of the elastic support mechanism 4, and the previous process is repeated to finish blanking of the two groups of templates pre-installed on the blanking box 2 one by one.
And step eight, after all the templates on the blanking box 2 are blanked. The controller sends a signal to the feeding mechanism 1, the feeding mechanism 1 supplements new two groups of templates into the blanking box 2 after receiving the signal, and then repeats the blanking operation steps on the blanking box 2 until all the template groups on the feeding mechanism 1 finish blanking through the blanking box 2.
