Description

Technical Field

[0001] The present application relates to the technical field of agricultural product feed production, and specifically discloses an agricultural product feed conveying and screening device. Background Art

[0002] Agricultural product feed refers to animal feeding materials made from food crops, oil crops, forages, and other agricultural and sideline products through processing, and is a key link connecting agriculture and animal husbandry.

[0003] Generally, in the production process of agricultural product feed, it will go through processes such as impurity removal, crushing, granulation, drying, spraying, and warehousing. Among them, during the conveying processes of granulation, drying, spraying, and warehousing, due to the collision of agricultural product feed during the processing process or during the conveying process, some powder substances are easily generated. If the powder substances are not screened, it will not only affect the finished product quality of agricultural product feed, but also increase the production cost.

[0004] In the current processing process, usually the powder substances in agricultural product feed are screened before each process step, which not only increases the production equipment and cost, but also prolongs the production steps and processes, that is, the production efficiency is reduced. Therefore, in view of this, the present invention provides an agricultural product feed conveying and screening device to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem that in the traditional conveying process of agricultural product feed, the particulate matter in the agricultural product feed cannot be screened in time, resulting in the prolongation of production steps and processes and the reduction of production efficiency.

[0006] To achieve the above purpose, the basic scheme of the present invention provides an agricultural product feed conveying and screening device, including:

[0007] A support frame;

[0008] A conveying component arranged on the support frame, including a roller arranged on the support frame, a feed pipe arranged at one end of the roller, a discharge pipe arranged at the other end of the roller, a spiral conveying roller rotatably connected inside the roller, and a driving mechanism for driving the rotation of the spiral component roller;

[0009] A screening cylinder arranged inside the roller. The side wall of the screening cylinder is respectively provided with notches communicated with the feed pipe and the discharge pipe. A plurality of screening holes are evenly arranged on the screening cylinder. The spiral conveying roller rotates along the inner wall of the screening cylinder. A slag discharge gap is formed between the outer wall of the screening cylinder and the inner wall of the roller. A slag discharge pipe is arranged at one end of the screening cylinder.

[0010] The principle and effect of this basic scheme are as follows:

[0011] Compared with the prior art, by providing a screening cylinder in the present invention, during the process of driving the spiral conveyor roller to rotate through a driving mechanism to convey agricultural product feed, the powder contained in the agricultural product feed falls from the screening holes of the screening cylinder into the slag discharge gap and is discharged from the slag discharge pipe, thereby completing the screening process of the powder in the agricultural product feed during the conveying process, avoiding the screening process of the powder in the agricultural product feed before each process step, reducing the equipment cost, that is, effectively solving the problem that in the traditional conveying process of agricultural product feed, the particulate matter in the agricultural product feed cannot be screened in time, resulting in the extension of the production steps and processes and the reduction of production efficiency.

[0012] Furthermore, it further includes a scraper provided in the slag discharge gap, driven by the driving mechanism and scraping along the outside of the screening cylinder. By providing the scraper, the powder adhered to the screening cylinder can be scraped off in time to prevent the screening holes from being blocked due to the long-term accumulation of powder and affecting the normal screening performance of the screening cylinder.

[0013] Furthermore, the driving mechanism includes:

[0014] A power component;

[0015] A roller shaft, rotatably connected to the roller and drivingly connected to the output end of the power component;

[0016] A conversion gear, coaxially connected to the roller shaft and drivingly connected to the output end of the power component, with one end of the scraper connected to the side wall of the conversion gear. By driving the roller shaft and the conversion gear to rotate through the power component, and then respectively driving the spiral conveyor roller to rotate for screening the agricultural product feed and driving the scraper to rotate to scrape off the powder adhered to the screening cylinder, the debugging, control and later maintenance costs of the driving mechanism are lower.

[0017] Furthermore, dividing strips for dividing the slag discharge gap vertically are symmetrically provided in the slag discharge gap, and a plurality of air inlet pipes for introducing dry hot air into the roller are communicated with the top of the roller. By introducing dry hot air into the roller, the agricultural product feed during the conveying process can be dried to prevent the agricultural product feed from being affected by moisture absorption and caking during the conveying process and affecting the finished product quality of the agricultural product feed.

[0018] Furthermore, the driving mechanism further includes:

[0019] A sector gear, coaxially connected to the roller shaft;

[0020] A sliding frame, with top teeth and bottom teeth that can mesh with the sector gear respectively provided at the top and bottom of the sliding frame, and the conversion gear meshes with one of the top teeth or the bottom teeth.

[0021] By setting the sector gear and the sliding carriage, when the driving mechanism drives the roller shaft to rotate, the sector gear meshes with the top teeth and the bottom teeth on the sliding carriage respectively, so that the sliding carriage slides reciprocally. Then, by continuously meshing one of the top teeth or the bottom teeth with the conversion gear, the conversion gear and the scraper are driven to swing reciprocally, so that the scraper swings in the slag discharge gap, which not only avoids the interference between the scraper and the dividing strip, but also prevents the scraper from bringing the powder into the top of the slag discharge gap, thus preventing the problem that the powder re-enters the inside of the screening cylinder.

[0022] Further, the difference between the tooth width of the bottom teeth and the tooth width of the top teeth is not less than the tooth width of the conversion gear, so as to facilitate the mutual cooperation of the top teeth, the bottom teeth, the sector gear and the conversion gear.

[0023] Further, a separation assembly is provided in the slag discharge pipeline, including:

[0024] A fan blade, which is arranged in the slag discharge pipeline and makes the air flow in the slag discharge pipeline flow spirally;

[0025] A separation cylinder, including an inner cylinder body extending into the slag discharge pipeline and an outer cylinder body located outside the slag discharge pipeline. A slag flow channel is formed between the inner cylinder body and the slag discharge pipeline, and an air flow channel communicating with the inside of the slag discharge pipeline is formed inside the inner cylinder body;

[0026] A transmission mechanism for driving the fan blade to rotate.

[0027] The transmission mechanism drives the fan blade to rotate, so that the air flow in the slag discharge pipeline flows spirally, the powder is thrown to the inner wall of the slag discharge pipeline, and then enters the separation cylinder along the slag flow channel, and the air enters the air flow channel and is discharged.

[0028] Further, the transmission mechanism includes a transmission shaft, a bevel gear pair arranged between the transmission shaft and the roller shaft, and a gear pair arranged between the transmission shaft and the outside of the fan blade, so as to facilitate driving the fan blade to rotate by the rotation of the roller shaft, making the transmission more compact and the control cost lower.

[0029] Based on the same inventive concept, the present invention provides a method for transporting and screening agricultural product feed, including transporting and screening the agricultural product feed using the above-mentioned agricultural product feed transporting and screening device.

[0030] Further, the steps of transporting and screening the agricultural product feed using the above-mentioned agricultural product feed transporting and screening device are as follows:

[0031] Step S1, introducing the agricultural product feed after the previous processing process into the screening cylinder through the feed pipe;

[0032] Step S2: The driving mechanism drives the spiral conveyor roller to rotate, driving the agricultural product feed to move. Meanwhile, during the movement, the powder material falls from the screening holes of the screening cylinder into the slag discharge gap and is discharged from the slag discharge pipe.

[0033] Step S3: After the conveying and screening are completed, the agricultural product feed enters the next processing station through the discharge pipe.

[0034] This method can complete the screening process of the powder material in the agricultural product feed during the conveying process, avoiding the screening process of the powder material in the agricultural product feed before each process step, reducing the equipment cost, that is, effectively solving the problem that in the traditional conveying process of agricultural product feed, the particulate matter in the agricultural product feed cannot be screened in time, resulting in the extension of the production steps and processes and the reduction of production efficiency.
