The delivery platform 9 includes an outer diagonal brace 91, a column 92, a crossbeam 93, a long longitudinal beam 94, and a main load-bearing beam 95; the outer diagonal brace 91, the column 92, the crossbeam 93 and the long longitudinal beam 94 form a gantry truss structure, the main load-bearing beam 95 is installed across the top of the long longitudinal beam 94, and the main load-bearing beam 95 is provided with a delivery hoisting interface, and the projection position of the delivery hoisting interface corresponds to the receiving platform 25. When in use, the delivery object is hung on the delivery hoisting interface, and the delivery hoisting interface is unlocked to make the delivery object fall, and the delivery object falls to the receiving platform 25, rolling down along the inclined surface, and continuing to roll along the extension direction of the guide frame 21 due to inertia until it is stopped by the stop pile 1.

[0020] Furthermore, it also includes a mobile operating platform 3, which is a ladder-shaped frame structure and is used to install the delivered objects on the delivery hoisting interface.

[0021] Furthermore, it also includes a curtain wall 8 made of transparent or semi-transparent material and arranged outside the track 23 .

[0022] Used for protection and to facilitate observation of the falling status of dropped objects.

[0023] Furthermore, the surface of the shock-absorbing pad 4 is provided with grooves to reduce the contact area with the object to be thrown, thereby further reducing the friction.

[0024] Furthermore, the receiving surface of the stop pile 1 is arranged with an anti-collision rubber strip to cushion the impact force of the dropped objects.

[0025] Furthermore, a pushing mechanism 5 is provided at the top of the inclined surface for providing a thrust to the falling objects in the extension direction of the track 23 . Furthermore, the pushing mechanism 5 includes a base 51, a buffer 52, a pushing fork 53, a support frame 54, a side support 55, a linear guide pair 56, a servo electric cylinder 57, a tail hinge seat 58, and a rear support 59; wherein the base 51 adopts a frame structure, with the side support 55 installed on its upper part, and the rear support 59 installed on the upper part of its rear end, and the base 51, the side support 55 and the rear support 59 constitute the base of the pushing mechanism 5; the buffer 52 is installed at the front end of the pushing fork 53, and the pushing fork 53 is installed in the support frame 54, and the support frame 54 is fixedly connected to the side support 55 through the linear guide pair 56; the cylinder body of the servo electric cylinder 57 is connected to the rear support 59 through the tail hinge seat 58, and the push rod of the servo electric cylinder 57 is connected to the pushing fork 53 through a pin shaft; under the action of the push rod of the servo electric cylinder 57, the pushing fork 53 reciprocates along the direction specified by the linear guide pair 56 to push away the object to be put.

[0026] Furthermore, it also includes a photoelectric sensor assembly 6 and an operating table 7. The photoelectric sensor assembly 6 is composed of a sensor and a reflector. The photoelectric sensor assembly 6 is arranged on the delivery stand 9 and is used to detect the delivery trajectory of the delivered object and generate a collection signal. The operating table 7 receives the collection signal of the photoelectric sensor assembly 6 and controls the push mechanism 5 to move and push the delivered object according to the collection signal. The operating table 7 can be a control device such as a computer.

[0027] According to one embodiment of the utility model, Figure 1-4As shown, the sensors and reflectors of the photoelectric sensor assembly 6 are arranged at both ends of the delivery platform, with an interval of 9m, and the delivery trajectory of the delivered object just passes through the sensor light-sensing area. The buffer 52 includes a polyurethane sponge, which can reduce the impact of the screw mechanism inside the servo electric cylinder 57. The control panel 7 has two control modes, manual and automatic. It can receive and process the delivery object existence signal collected by the photoelectric sensor assembly, and then control the two groups of electric push mechanisms to move synchronously. It also has overcurrent and emergency protection functions. The curtain wall 8 is a bulletproof curtain wall with a modular design. There are 5 groups in total, which can be seamlessly connected together to protect the safety of the operator. Each group of curtain walls is protected by high-strength composite bulletproof glass, and a lifting caster is set at the bottom to facilitate movement and fixation. The control panel 7 is located behind the bulletproof curtain wall 8 outside the delivery platform 9, and personnel are located here to operate. The patterned steel plate 24 is installed on the inclined surface of the receiving platform 25 by screws, and a shock-absorbing pad 4 is arranged above the patterned steel plate 24. When the object is separated from the launching device under the control of the delivery signal, it falls on the shock-absorbing pad 4. At this time, the photoelectric sensor component 6 detects the falling of the bullet and transmits the signal to the operating console 7, thereby controlling the action of the electric pushing mechanism 5, pushing the object away from its original position, and rolling it along the top track 23 of the guide frame 21 to the stop pile 1. At this time, the servo electric cylinder of the electric pushing mechanism 5 is reset to prepare for subsequent continuous delivery.
