Description

Technical Field

[0001] The utility model relates to the technical field of cement production equipment, in particular to a bulk cement discharge port device. Background Art

[0002] In the bulk cement transportation industry, docking the cement discharge port with the cement delivery vehicle's feed port is a vital task. In existing technologies, this docking process mainly relies on manual operation. Specifically, the staff needs to drive the vehicle to the designated area first, align the vehicle's left front wheel with the ground mark to determine whether the upper discharge port and the cement delivery vehicle's feed port are aligned, and then manually adjust the position of the corrugated pipe to align it precisely with the cement delivery vehicle's feed port. This operation method has the following obvious defects:

[0003] First, factors such as the driver's seat height, height, and driving experience will affect the alignment accuracy between the left front wheel of the vehicle and the ground mark. If the driver's driving experience is insufficient, it is impossible to ensure that the vehicle can be parked at the corresponding position every time, so the vehicle position still needs to be adjusted many times, which consumes a lot of time;

[0004] Secondly, manual docking is inefficient, and the height of the cement truck is relatively high, so the docking personnel need to climb to a higher place to complete the manual docking, which poses a risk of falling. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a bulk cement discharge port device to overcome the deficiencies in the above-mentioned prior art.

[0008] It also includes a control terminal, and the electric telescopic rod, the first motor, the second motor and the visual detection camera are all electrically connected to the control terminal; the upper end of the first telescopic tube is connected to the silo.

At this time, the docking personnel drives the electric telescopic rod through the control terminal to move the pipe mouth downward to complete the docking of the pipe mouth and the feed port; during the entire docking process, there is no need to accurately park according to ground markings, nor is there any need for the docking personnel to climb to a high place for manual docking, and after the device is positioned, the position of the pipe mouth can be fixed due to the support of the electric telescopic rod, thereby avoiding the existing corrugated pipe from shaking out of the feed port of the cement delivery truck due to the impact of cement during the unloading process.

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] like Figure 1-2 As shown, in Example 1, a bulk cement discharge port device comprises a rectangular base 10, a telescopic discharge pipe 20 and a driving mechanism 30; the discharge pipe 20 comprises a first telescopic pipe 201, a first fixing ring 202, a second telescopic pipe 203, a second fixing ring 204 and a pipe mouth 205 connected in sequence from top to bottom, the first fixing ring 202 and the second fixing ring 204 are connected by an electric telescopic rod 206; the lower end surface of the second fixing ring 204 is provided with a visual detection camera 207;

[0023] The driving mechanism 30 includes a first motor 301, a second motor 302, a first screw rod 303, a second screw rod 304, a first nut seat 305 and a second nut seat 306. The rotating shaft of the first motor 301 is connected to the first screw rod 303, the first nut seat 305 moves linearly on the first screw rod 303, the second motor 302 is connected to the first nut seat 305, the rotating shaft of the second motor 302 is connected to the second screw rod 304, the second nut seat 306 moves linearly on the second screw rod 304, and the second nut seat 306 is connected to the first fixing ring 202; the first screw rod 303 is located on one side of the rectangular base 10, the second screw rod 304 is perpendicular to the first screw rod 303, and parallel to the other side of the rectangular base 10;

[0024] It also includes a control terminal, and the electric telescopic rod 206, the first motor 301, the second motor 302 and the visual detection camera 207 are all electrically connected to the control terminal; the upper end of the first telescopic tube 201 is connected to the silo.

[0025] When the cement delivery truck stops at the parking area, the visual detection camera 207 collects the image of the feed port of the cement delivery truck in real time and transmits the image to the control terminal. The docking personnel drives the first motor 301 and / or the second motor 302 to rotate by controlling the position of the feed port in the image displayed on the control terminal. When the position of the feed port in the image is located in the calibration area in the image, it indicates that the pipe mouth 205 is located directly above the feed port. At this time, the docking personnel drives the electric telescopic rod 206 through the control terminal to move the pipe mouth 205 downward to complete the docking of the pipe mouth 205 with the feed port. During the entire docking process, there is no need to accurately park according to the ground markings, nor is there any need for the docking personnel to climb to a high place for manual docking. After the device is positioned, due to the support of the electric telescopic rod 206, the position of the pipe mouth 205 can be fixed, thereby preventing the existing corrugated pipe from shaking out of the feed port of the cement delivery truck due to the impact of cement during the unloading process.

[0026] It should be noted that the position of the visual inspection camera 207 on the lower end surface of the second fixed ring 204 is fixed, which is equivalent to the fixed position of the visual inspection camera 207 relative to the pipe mouth 205, and further equivalent to the fixed position of the visual inspection camera 207 relative to the feed port of the cement delivery truck directly below the pipe mouth 205. When the pipe mouth 205 is moved to directly above the feed port through the first motor 301 and / or the second motor 302, the shooting angle of the visual inspection camera 207 to the feed port is consistent, and the feed port is located in a fixed area in the image. This fixed area is marked in advance and is the calibration area.

[0027] In a specific implementation, the control terminal includes a display screen for displaying images, and also includes a driving button for driving the first motor 301 , the second motor 302 and the electric telescopic rod 206 .
