Description

Technical Field

[0001] The invention relates to the field of grain conveying, in particular to a grain scraper conveyor. Background Art

[0002] In the process of conveying grains, the conveying of grains is usually achieved through scraper conveyors, which are suitable for a variety of grains and different conveying environments. Whether it is raw grains such as wheat, corn, and rice, or processed materials such as flour, bran, and cake, scraper conveyors can effectively convey them.

[0003] Scraper conveyor is usually a continuous transport device that uses moving chains and scrapers to transport grain materials in a closed rectangular cross-section shell. It uses the power transmission between the chain and the rotating shaft to move the scraper along the bottom of the trough inside the shell. When a discharge port is opened at the bottom of the trough, the scraper pushes the grain material out of the discharge port, thereby realizing the transportation of the grain material.

[0004] With respect to the above-mentioned related technologies, when the grain materials are transported in the shell of the scraper conveyor, the transported grain materials are easily attached to the scraper and are always circulated and transported together with the scraper, which makes it difficult to ensure the transport effect of the grain materials. Summary of the invention

[0005] In order to prevent the transported grain materials from always being circulated and transported together with the scraper, thereby ensuring the transport effect of the grain materials, the present application provides a grain scraper conveyor.

[0007] By adopting the above technical scheme, when the grain material is fed into the shell, the driving wheel is driven to rotate through the transmission drive member so that the transmission chain drives each scraper to circulate and transport in the shell, thereby discharging the grain material through the discharge port. Subsequently, when the scraper continues to transport, the grain material attached to the scraper is also discharged from the discharge port under the blocking effect of the curtain, so that the grain material transported in the shell is not easy to be always circulated and transported together with the scraper, which is beneficial to ensure the transportation effect of the grain material. The setting of the curtain to limit the transported grain material makes the limiting effect of the grain material softer, and it is not easy for the transported grain material to be damaged by excessive impact. At the same time, it also makes it difficult for the material transported in the shell to move with the scraper to the inner wall of the shell, which is beneficial to ensure the cleanliness of the inside of the shell and facilitates the subsequent cleaning of the inside of the shell.

[0008] Optionally, the material blocking mechanism also includes a reset assembly, which includes a reset fixing rod, a reset connecting seat, a reset connecting rod and a reset torsion spring. The reset fixing rod is horizontally arranged in the shell, the reset connecting seat is sleeved and slidably fitted on the reset fixing rod, one end of the reset connecting rod is rotatably installed on the reset connecting seat, and the other end is installed on the blocking curtain, and the reset torsion spring is used to reset the reset connecting rod.

[0009] By adopting the above technical solution, the elastic effect of the reset torsion spring facilitates the stable reset of the barrier curtain, which is beneficial to further ensure the barrier curtain's material blocking performance for conveying grain materials.

[0010] Optionally, the material blocking fixed seat is provided with a lifting component for driving the reset fixed rod to move in the vertical direction, the lifting component includes a lifting screw and a lifting guide rod, the lifting screw is vertically rotatably installed on the material blocking fixed seat, the lifting screw is passed through and threadedly engaged with the reset fixed rod, the lifting guide rod is vertically fixedly installed on the material blocking fixed seat, the lifting guide rod is passed through and slidably engaged with the reset fixed rod, and the reset connecting rod is a telescopic rod.

[0011] By adopting the above technical scheme, when the lifting screw is rotated, the reset fixing rod cooperates with the thread of the lifting screw and moves in the vertical direction under the limiting action of the lifting guide rod, so that it is easy to adjust the blocking height of the grain material by the barrier curtain, and it is easy to adapt to different grain material conveying conditions in the shell. It has strong applicability, and the setting of the reset connecting rod as a telescopic rod facilitates the synchronous realization of adaptive adjustment of the height of the reset fixing rod, so that the barrier curtain can always be reset stably.

[0012] Optionally, one end of the lifting screw is fixedly connected to a lifting handwheel.

[0014] Optionally, a plurality of the blocking curtains are evenly distributed along the axial direction of the material blocking fixing seat, and a plurality of the reset components are arranged in a one-to-one correspondence with the blocking curtains.

[0015] By adopting the above technical solution, the setting of multiple barrier curtains makes it easier for the barrier curtains to form a denser barrier layer, increasing the probability of grain materials being blocked during transportation and improving the blocking effect. At the same time, it is beneficial to disperse the impact force and friction force of grain materials on the barrier curtains when a single barrier curtain is used, thereby improving the stability and durability of the entire material blocking mechanism.

[0016] Optionally, one end of the reset torsion spring is fixedly connected to the reset connecting seat, and the other end is fixedly connected to the reset connecting rod. The outer peripheral surface of the reset connecting seat is provided with a plurality of fixing holes circumferentially distributed around its own axis. The reset connecting seat is tightly fixed to the reset fixing rod by a fixing bolt threadedly engaged with one of the fixing holes.

[0017] By adopting the above technical solution, the reset connecting seat is rotated to different angles so that the fixing bolts are passed through different fixing holes to achieve tight fixation of the reset connecting seat, and the torque of the reset torsion spring can be adjusted, thereby facilitating the adaptive adjustment of the curtain according to the conveying speed and quantity of the grain material, thereby ensuring a stable blocking effect during the conveying of the grain material and avoiding unstable blocking caused by excessive or insufficient torque.

[0018] Optionally, a positioning hole is formed on the outer peripheral surface of the reset connecting rod, and a positioning bolt is fitted into the inner thread of the positioning hole.

[0019] By adopting the above technical solution, the positioning bolt is screwed so that the positioning bolt is pressed or not pressed against the reset connecting seat, thereby achieving the fixing or loosening of the position of the reset connecting rod. Therefore, when the curtain is not needed to block and limit the conveyed grain materials, the position of the curtain can be quickly and adaptively adjusted. At the same time, it is also convenient to firmly fix the curtain in a specific position so that the curtain can always achieve stable limitation of the conveyed grain materials.

[0020] Optionally, the reset fixing rod is provided with a material stopping position limiting portion, and the material stopping position limiting portion is used to limit the rotation of the curtain.

[0021] By adopting the above technical solution, the material blocking limiting part plays a role in limiting the rotation of the material blocking, so that the blocking curtain can quickly return to its original position after blocking the conveyed grain material.

[0022] Optionally, a support assembly is installed in the shell, and the support assembly includes a support fixing rod and a support bearing plate. The support fixing rod is horizontally fixed in the shell and multiple support fixing rods are evenly distributed along the length direction of the shell. The support bearing plate is fixedly installed on the top of each support fixing rod, and the support bearing plate is used to support the scraper transported at the top.

[0025] By adopting the above technical solution, the two adjusting nuts can be loosened so that the two adjusting nuts are fixed at different length positions of the adjusting screw rod to adjust the position of the adjusting seat and the driven wheel, that is, to adjust the tension of the transmission chain, which is convenient and stable. During the adjustment of the driven wheel position, the adjusting baffle always closes the opening of the adjusting groove, so that the grain material is not easy to flow out of the shell through the opening of the adjusting groove, which is beneficial to further ensure the stability of the grain material during transportation.

The driving wheel 6 is coaxially fixed with a rotating shaft 10, and the rotating shaft 10 is passed through the outside of the housing 1 and rotated on the output end of the reducer 9, so that the transmission motor 8 drives the driving wheel 6 to rotate through the reducer 9 and the rotating shaft 10.

[0039] Continue to refer to Figure 2 and Figure 3 Two fixing plates 11 are fixedly installed outside the shell 1, and the two fixing plates 11 are respectively located on both sides of the width direction of the shell 1. The shell 1 is also provided with an adjustment component, and two groups of adjustment components are provided corresponding to the fixing plates 11. The adjustment component includes an adjustment screw 12, a fixing nut 13, an adjustment nut 14, an adjustment seat 15 and an adjustment baffle 16, wherein the adjustment screw 12 is arranged along the length direction of the shell 1, and the two fixing nuts 13 are threadedly matched with the outer peripheral surface of the adjustment screw 12, and the fixing plate 11 is located between the two fixing nuts 13. By screwing the two fixing nuts 13, the two fixing nuts 13 are pressed against the fixing plate 11 to achieve the fixation of the position of the adjustment screw 12, that is, the adjustment screw 12 is fixedly installed on the outside of the shell 1.

[0040] Continue to refer to Figure 2 and Figure 3The adjusting screw 12 is inserted into the adjusting seat 15 and slides with the adjusting seat 15. Two adjusting nuts 14 are provided and both are threadedly engaged with the adjusting screw 12. The adjusting seat 15 is located between the two adjusting nuts 14. The two adjusting nuts 14 are loosened so that the two adjusting nuts 14 press and fix the adjusting seat 15 at different length positions of the adjusting screw 12 to adjust the position of the adjusting seat 15. Both sides of the width direction of the housing 1 are provided with adjusting grooves 17 extending along the length direction of the housing 1.

The two ends of the driven shaft 18 slide and fit in the two adjusting grooves 17 respectively, and the two ends of the driven shaft 18 are rotatably mounted on the two adjusting seats 15 respectively, so that when the adjusting seat 15 is adjusted in position, the position of the driven wheel 7 is adjusted at the same time. The transmission chain 4 is in a ring shape connected end to end and is wound around the driving wheel 6 and the transmission wheel and meshed with the driving wheel 6 and the transmission wheel. When the position of the driven wheel 7 is adjusted, the tension of the transmission chain 4 is adjusted synchronously, which is convenient and stable.

[0041] Reference Figure 1 and Figure 3 The adjusting baffle 16 is fixedly mounted on the adjusting seat 15. The housing 1 is provided with an adjusting chute 19 extending along its length direction. Two groups of adjusting chute 19 and adjusting baffle 16 are provided correspondingly. Each group of adjusting chute 19 is provided with two adjusting chute 19. The two sides of the adjusting baffle 16 in the height direction slide and fit in the two adjusting chute 19 of each group respectively. When the adjusting seat 15 is fixed at different length positions of the adjusting screw 12, the adjusting baffle 16 slides in the adjusting chute 19 and always closes the opening of the adjusting slot 17, so that the grain material transported in the housing 1 is not easy to flow out of the housing 1 through the opening of the adjusting slot 17. The adjusting chute 19 plays a role in limiting the position of the adjusting baffle 16 when it moves, which is conducive to ensuring the stability of the adjusting baffle 16 when it moves. The scraper 5 is rotated on the transmission chain 4 and is evenly distributed along the length direction of the transmission chain 4. When the transmission motor 8 drives the driving wheel 6 to rotate, the driven wheel 7 and the transmission chain 4 move synchronously, so that each scraper 5 can realize the transmission and transportation of the grain material in the housing 1.

[0042] Reference Figure 2 and Figure 4The material blocking mechanism is arranged at the discharge port 3, and the material blocking mechanism includes a material blocking fixing seat 20 and a blocking curtain 21, wherein the two ends of the material blocking fixing seat 20 in the length direction are respectively fixedly installed on the two inner walls of the shell 1, and the blocking curtain 21 is installed at the bottom of the material blocking fixing seat 20, and a plurality of blocking curtains 21 are evenly distributed along the axial direction of the material blocking fixing seat 20, and adjacent two blocking curtains 21 abut against each other, so that each blocking curtain 21 forms a dense blocking layer for blocking the grain material transported to the discharge port 3. When the scraper 5 transports the grain material to the discharge port 3 and continues to transport it, the grain material attached to the scraper 5 is also discharged from the discharge port 3 under the blocking effect of the blocking curtain 21, so that the grain material transported in the shell 1 is not easy to be always circulated and transported together with the scraper 5, which is beneficial to ensure the transportation effect of the grain material.

[0043] Reference Figure 4 and Figure 5 Furthermore, the material blocking mechanism also includes a reset component, which includes a reset fixing rod 22, a reset connecting seat 23, a reset connecting rod 24 and a reset torsion spring 25, wherein the reset fixing rod 22 is horizontally arranged in the shell 1 and is located on one side of the output direction of the curtain 21, and the material blocking fixing seat 20 is provided with a lifting component for driving the reset fixing rod 22 to move in the vertical direction. Specifically, the lifting component includes a lifting screw 26 and a lifting guide rod 27, wherein the lifting screw 26 is vertically rotatably installed on the material blocking fixing seat 20, the lifting screw 26 is penetrated and threadedly matched with the reset fixing rod 22, the lifting guide rod 27 is vertically fixedly installed on the material blocking fixing seat 20, the lifting guide rod 27 is penetrated and slidably matched with the reset fixing rod 22, and one end of the lifting screw 26 is fixedly connected with a lifting handwheel 28, so that the staff can apply force to realize the rotation of the lifting screw 26. When the lifting screw 26 rotates, the reset fixing rod 22 cooperates with the thread of the lifting screw 26 and moves in the vertical direction under the limiting action of the lifting guide rod 27, so that it is convenient to adjust the blocking height of the grain material in the shell 1 by the curtain 21, so as to adapt to different grain material conveying conditions.

[0044] Continue to refer to Figure 4 and Figure 5, a plurality of reset connecting seats 23, reset connecting rods 24 and reset torsion springs 25 are arranged in a one-to-one correspondence with the curtain 21, the reset connecting seat 23 is sleeved and slidably matched with the reset fixing rod 22 along the axial direction of the reset fixing rod 22, the reset connecting rod 24 is a telescopic rod, and one end of the reset connecting rod 24 is rotatably installed on the reset connecting seat 23, and the other end is installed on the curtain 21, the reset torsion spring 25 is sleeved outside the reset connecting seat 23, and one end of the reset torsion spring 25 is fixedly connected to the reset connecting seat 23, and the other end is fixedly connected to the reset connecting rod 24, so that the curtain 21 can be reset stably through the elastic force of the reset torsion spring 25, thereby fully ensuring the material blocking performance of the curtain 21 for conveying grain materials. In addition, the setting of the reset connecting rod 24 as a telescopic rod facilitates the synchronous realization of adaptive adjustment when adjusting the height of the reset fixing rod 22, thereby facilitating the stable reset of the curtain 21 at all times.

[0045] Reference Figure 5 and Figure 6 To ensure the stability of the position of the curtain 21 after it is reset, the reset fixing rod 22 is fixedly installed with a material stopping limit part 29, which is L-shaped. The material stopping limit part 29 includes a vertical section 291 fixedly installed on the reset fixing rod 22 and a horizontal section 292 fixedly connected to the bottom of the vertical section 291. The curtain 21 is located between the horizontal section 292 and the reset connecting rod 24. In normal state, the horizontal section 292 presses the curtain 21 to achieve a limiting effect on the position of the curtain 21, so as to facilitate the stable reset of the curtain 21 after rotation.

[0046] Reference Figure 4 and Figure 5 In order to facilitate the adjustment of the elastic force of the reset torsion spring 25, and thus facilitate the adaptive adjustment of the blocking force of the curtain 21 according to the conveying speed and quantity of the grain material, a plurality of fixing holes 30 distributed circumferentially around its own axis are opened on the outer peripheral surface of the reset connecting seat 23. The reset connecting seat 23 is fixed to the reset fixing rod 22 by a fixing bolt 31 that is threadedly engaged with one of the fixing holes 30 and presses against the reset fixing rod 22. By rotating the reset connecting seat 23 to different angles so that the fixing bolt 31 is passed through different fixing holes 30 to achieve the tight fixation of the reset connecting seat 23, the torque of the reset torsion spring 25 can be adjusted, which is convenient and stable.

[0047] Continue to refer to Figure 4 and Figure 5The outer surface of the reset connecting rod 24 is provided with a positioning hole 32, and the inner thread of the positioning hole 32 is matched with a positioning bolt 33. On the one hand, when the curtain 21 is not needed to block and limit the conveyed grain materials, the reset connecting rod 24 is rotated to the position where the curtain 21 does not block the conveyed grain materials, and the positioning bolt 33 is screwed so that the positioning bolt 33 is pressed against the reset connecting seat 23 to fix the position of the reset connecting rod 24; on the other hand, the curtain 21 can also be firmly fixed to a specific position by pressing the positioning bolt 33 against the reset connecting seat 23, so that the curtain 21 can always achieve stable limiting of the conveyed grain materials, and the applicability is strong.

[0048] Reference Figure 2 and Figure 4 In order to further ensure the stability of the scraper 5 in the shell 1 when conveying grain materials, a support assembly is installed in the shell 1, and the support assembly includes a support fixing rod 34 and a support bearing plate 35, wherein the support fixing rod 34 is horizontally fixed in the shell 1 and a plurality of support fixing rods 34 are evenly distributed along the length direction of the shell 1, and the support bearing plate 35 is fixedly installed on the top of each support fixing rod 34, and each support fixing rod 34 and support bearing plate 35 are located in the enclosed area of ​​the transmission chain 4. The scraper 5 conveyed at the top of the shell 1 abuts against the top of the support bearing plate 35 during transmission, so that the support bearing plate 35 can support the scraper 5 conveyed near the top of the shell 1.

[0049] The implementation principle of a grain scraper conveyor in the embodiment of the present application is as follows: when the grain material is fed into the shell 1, the driving wheel 6 is driven to rotate by the transmission motor 8 so that the transmission chain 4 drives each scraper 5 to circulate and convey in the shell 1, thereby discharging the grain material through the discharge port 3. Subsequently, when the scraper 5 continues to convey, the grain material attached to the scraper 5 is also discharged from the discharge port 3 under the blocking effect of the curtain 21, so that the grain material transported in the shell 1 is not easy to be always circulated and conveyed together with the scraper 5, which is beneficial to ensuring the transportation effect of the grain material. The setting of the curtain 21 to limit the transported grain material makes the limiting effect of the grain material softer, and it is not easy for the transported grain material to be damaged by excessive impact. At the same time, it is also difficult for the material transported in the shell 1 to move to the inner wall of the shell 1 with the scraper 5, which is beneficial to ensuring the cleanliness of the inside of the shell 1 and facilitating the subsequent cleaning of the inside of the shell 1.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
