Description

Technical Field

[0001] The utility model belongs to the technical field of material conveying equipment, in particular to a scraper conveyor. Background Art

[0002] In the transportation of materials such as ore, a belt transmission device is usually used for material transmission. However, the belt transmission device usually takes away some materials when the belt returns, resulting in that some materials cannot smoothly enter the receiving port, and most of these materials will be spilled on the ground during the belt return process, causing waste. Utility Model Content

[0003] In order to solve the deficiencies of the prior art, the utility model provides a scraper machine which can completely deliver materials into a material receiving port to prevent the materials from spilling.

[0004] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0005] A scraper machine comprises a material trough and a scraper.

[0006] There are drive components on both sides of the trough, and sensors on both ends of the trough;

[0007] Connecting shafts are provided at both ends of the scraper, and the connecting shafts at both ends are rotatably arranged on a connecting block respectively. The scraper is arranged in the trough, and the angle between the scraper and the bottom surface of the discharge end of the trough is an obtuse angle; the connecting blocks are respectively connected to the driving components on both sides of the trough, and the scraper is driven to reciprocate along the two ends of the trough by the driving components. The sensor is used to detect and transmit the scraper in place signal to the driving component.

[0008] The beneficial effect of the utility model is that the structure can not only prevent the material from being scattered and make all the material fall into the material receiving port, but also prevent the material from being accumulated in the material trough, thereby accelerating the material conveying speed.

[0014] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0015] like Figures 1 to 3 As shown, a scraper machine includes: a material trough 1 and a scraper 2.

[0016] Specifically, driving components are provided on both sides of the trough 1 , and sensors 11 are provided on both ends of the trough 1 .

[0017] Specifically, connecting shafts 21 are provided at both ends of the scraper 2, and the connecting shafts 21 at both ends are rotatably arranged on a connecting block 22 respectively. The scraper 2 is arranged in the material trough 1, and the angle between the scraper 2 and the bottom surface of the discharge end of the material trough 1 is an obtuse angle; the connecting blocks 22 are respectively connected to the driving components on both sides of the material trough 1, and the scraper 2 is driven to reciprocate along the two ends of the material trough 1 through the driving components. The sensor 11 is used to detect and transmit the scraper 2 in place signal to the driving component.

[0018] Working principle: the material is fed in from the front end of the trough 1 and discharged from the rear end of the trough 1; when scraping the material, the drive assembly drives the scraper 2 to move to the rear end of the trough 1 through the connecting block 22. Because the angle between the scraper 2 and the bottom surface of the discharge end of the trough 1 is an obtuse angle, when the scraper 2 is subjected to the resistance of the material, the lower side of the scraper 2 will slide in contact with the bottom of the trough 1, thereby pushing the material to the rear end of the trough 1 to complete the purpose of scraping. When the sensor 11 at the rear end of the trough 1 detects the scraper 2, the sensor 11 will transmit the scraper 2 arrival signal to the drive assembly, and the drive assembly will drive the scraper 2 to move to the front end of the trough 1. During the process of the scraper 2 moving toward the front end of the material trough 1, the material can be continuously conveyed inside the material trough 1, because the angle between the scraper 2 and the bottom surface of the discharge end of the material trough 1 is an obtuse structure, and the two ends of the scraper 2 are connected to the connecting block 22 by rotating through the connecting shaft 21, so the scraper 2 can avoid the material being conveyed inside the material trough 1 by swinging upward around the connecting shaft 21, so that the scraper 2 can move smoothly to the front end of the material trough 1; similarly, because the connecting shafts 21 at both ends of the scraper 2 rotate the connecting blocks 22 at both ends, the scraper 2 does not contact the bottom of the material trough 1 at the beginning of its movement, and it can also swing downward after encountering resistance, so that the bottom of the scraper 2 contacts the bottom of the material trough 1. When the sensor 11 at the front end of the trough 1 detects the scraper 2, it transmits the signal to the driving component again, and the driving component will drive the scraper 2 to move to the rear end of the trough 1 again, so as to achieve the purpose of reciprocating scraping. This structure can not only prevent the material from spilling and make all the materials fall into the receiving port, but also prevent the material from accumulating in the trough 1, speed up the material conveying speed, and avoid time-consuming and labor-intensive manual scraping operations.

[0019] As a preferred structure, the driving component is a linear cylinder or a linear motor; the sensor 11 is a proximity switch or a travel switch.

[0020] Preferably, the distance between the connecting shaft 21 and the lower edge of the scraper 2 is greater than the distance between the connecting shaft 21 and the upper edge of the scraper 2, so that the weight of the scraper 2 below the connecting shaft 21 is greater, thereby ensuring that the lower edge of the scraper 2 is always facing downward and preventing the scraper 2 from turning upside down.

[0021] Preferably, the scraper 2 is perpendicular to the conveying direction of the trough 1 so as to push the material in the trough 1 backward in parallel.

[0022] Preferably, the driving assembly includes a pair of ring chains 31 provided on both sides of the trough 1, and sprockets 32 connected to the ring chains 31 are provided at both ends of the trough 1. The sprockets 32 are driven by a motor, and the connecting blocks 22 are respectively connected to the ring chains 31 on both sides. Compared with linear cylinders and linear motors, this transmission structure takes up less space for installation, which can make the equipment more compact.

[0023] Further preferably, Figure 1 , Figure 2 As shown, the sprockets 32 on both sides of the same end of the trough 1 are coaxially connected through a transmission rod 33, and one of the transmission rods 33 is connected to a motor, so that one motor can be used to drive two ring chains 31 to rotate synchronously at the same time, thereby simplifying the overall structure of the equipment.

[0024] Preferably, Figure 2 As shown, the sensor 11 is a travel switch, and a disc 23 is provided at the end of the scraper 2 for triggering the travel switch. Compared with proximity switches and other sensing devices that rely on infrared detection, travel switches are more suitable for environments with heavy dust.

[0025] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
