[0029] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following will make a detailed description of the specific implementation manners of the present utility model with reference to the accompanying drawings of the specification.

[0030] Refer to Figures 1-9 , which is an embodiment of the present utility model, and provides a parallel scraper conveyor. This parallel scraper conveyor includes a machine body 1, a driving shaft 2 and a driven shaft 3. The driving shaft 2 and the driven shaft 3 are arranged inside the machine body 1. A first driving wheel 21 is provided on the driving shaft 2. Second driving wheels 22 are symmetrically arranged on both sides of the first driving wheel 21. A driven wheel 31 is provided on the driven shaft 3. A first conveyor chain 4 is connected between the first driving wheel 21 and the middle driven wheel 31 in a matching manner. Second conveyor chains 5 are connected between the second driving wheels 22 and the driven wheels 31 on both sides in a matching manner. Scrapers 6 are arranged at intervals on the first conveyor chain 4.

[0031] A first wheel groove 211 is axially formed in the middle position of the first driving wheel 21. A second wheel groove 311 is formed in the middle driven wheel 31. The central cross-sections of the first wheel groove 211 and the second wheel groove 311 are in the same plane and have the same width. The first conveyor chain 4 passes through the first wheel groove 211 and the second wheel groove 311 to form a chain drive with the first driving wheel 21 and the middle driven wheel 31.

[0032] The first conveyor chain 4 is composed of a plurality of conveyor links, which improves the supporting force of the first conveyor chain 4. An earring is provided on one side of each conveyor link.

[0033] An ear clip rotatably connected to the earring is provided on one side of the scraper 6. An opening is formed in the scraper 6 at the position of the ear clip to prevent the conveyor link from rubbing against the earring during rotation.

[0034] Connecting bars 61 are fixedly connected to both sides of the scraper 6 close to the second conveyor chain 5. The other ends of the connecting bars 61 are connected to the second conveyor chain 5.

[0035] A support platform 13 is arranged below the second conveyor chain 5. One side of the support platform 13 is fixedly connected to the machine body 1. The two ends of the support platform 13 do not exceed the innermost points of the second driving wheel 22 and the outer driven wheels 31. One side of the support platform 13 close to the first conveyor chain 4 exceeds one side of the second wheel groove 311 close to the first conveyor chain 4.

[0036] The central cross-sections of the second pulley grooves 311 on the second driving pulley 22 and the outer driven pulley 31 are in the same plane and have the same width. The second transmission chain 5 passes through the second pulley grooves 311 and forms a chain drive connection with the second driving pulley 22.

[0037] The top of the machine body 1 is provided with a feed inlet 11, and a discharge outlet 12 is provided on one side of the machine body 1 close to the driven shaft 3.

[0038] One side of the driving shaft 2 passes through the machine body 1 and is connected with a speed reducer 7, and the other end of the speed reducer 7 is connected with an electric motor 8.

[0039] During use, the electric motor 8 operates. After being decelerated by the speed reducer 7, the driving shaft 2 rotates, and the first driving pulley 21 and the second driving pulley 22 thereon rotate accordingly, driving the first transmission chain 4 and the second transmission chain 5 to transmit. The scraper 6 above levels the material. During the transmission process, the second transmission chain 5 is more stable under the action of the support platform 13. In the whole process, the material can be continuously fed through the feed inlet 11 and continuously discharged through the discharge outlet 12.
