Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plate processing, especially relates to a single chain scraper conveyor. BACKGROUND

[0002] In wood processing enterprises, the collection of sawdust is generally carried out by using a dust collector to transport the sawdust out of the workshop through a pipeline under negative pressure. However, for wet sawdust, the dust collection power needs to be very large but the effect is not good, and manual cleaning is still required. Especially in some small wood processing plants, due to the lack of equipment and dispersion, when processing raw wood or wet boards, the wet sawdust generated cannot be treated by dust collection, and dry sawdust needs to be separately sucked by a dust collector, which is noisy and unsanitary. Therefore, manual cleaning is required every certain period of time, which is dangerous and affects work efficiency. SUMMARY

[0003] The utility model aims at providing a single chain scraper conveyor to solve the problems in the background art, so that it is suitable for collecting dry and wet sawdust and avoiding pipeline blockage caused by the high moisture content and heavy weight of wet sawdust.

[0008] A drive mechanism is fixed to the rack and connected to one end of one of the rotating shafts;

[0009] A plurality of scraper assemblies are provided and connected to the transmission chain.

[0010] Preferably, the rack is symmetrically connected to a limiting strip in front and back, and the limiting strip has a curvature that makes the plurality of scraper assemblies located in the lower half of the transmission chain lie in the same plane.

[0011] Preferably, the limiting strip has an upward curvature at both ends.

[0012] Preferably, the scraper assembly comprises a connecting piece connected to both ends of two adjacent pin shafts of the transmission chain.

[0013] A scraper is fixed to the side of the connecting piece away from the transmission chain.

[0014] Preferably, the scraper has rubber fixed to the side away from the connecting piece.

[0015] Preferably, the driving mechanism is a servo motor connected to the rotating shaft through a shaft coupling.

[0016] The utility model discloses the beneficial effects obtained:

[0017] The single-chain scraper conveyor of the utility model is suitable for collecting dry and wet sawdust, avoids pipeline blockage caused by the high moisture content and heavy weight of wet sawdust, and is more simple and efficient and lower in cost than the dust suction device.

[0022] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0023] In the description of the utility model, it should be understood that the terms "up", "down", "front", "back", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0024] Please refer to Figure 1 and Figure 2 A single-chain scraper conveyor comprises a rack 1.

[0025] Two rotating shafts 2 are rotatably connected to the rack 1, and the two rotating shafts 2 are arranged in parallel with each other.

[0026] Two sprockets 3 are fixed on the two rotating shafts 2 respectively.

[0027] The transmission chain 4 is in a ring shape and is connected to the two sprockets 3.

[0028] The driving mechanism 5 is fixed on the frame 1 and connected with one end of the rotating shaft 2;

[0029] The scraper assembly 6 is provided with a plurality of scraper assemblies 6 connected to the transmission chain 4 and located outside the chain 4. The scraper assembly is provided to scrape and clean the dry and wet sawdust, so as to be suitable for the collection of dry and wet sawdust, avoid the pipe blockage caused by the high moisture and heavy weight of the wet sawdust, and the device is more simple and efficient than the dust collection device, and has lower cost and smaller floor area, and is more suitable for the collection of wet sawdust after the discharge of small enterprises.

[0030] Please refer to Figure 1 and Figure 2 The scraper assembly 6 may scrape the heavy wet sawdust during scraping, so as to pass over the wet sawdust, resulting in incomplete scraping. Or the transmission chain 4 is in a loose state after long-time use, so as to pass over the large or heavy sawdust, thereby affecting the scraping effect. Therefore, in order to effectively adhere the scraper assembly 6 to the surface where the sawdust is located, avoid the scraper assembly 6 passing over or avoiding the sawdust, the limiting strip 7 is symmetrically connected on the frame 1, the limiting strip 7 has a plurality of scraper assemblies 6 located in the lower half of the transmission chain 4 in the same plane, and the limiting strip is arranged to make the plurality of scraper assemblies 6 in the lower half of the transmission chain 4 closely adhere to the surface where the sawdust is located, thereby improving the scraping effect.
