[0001] The invention relates to the field of conveying devices, in particular to an auger for conveying grains. Background Art

[0002] The grain conveying auger is a common material conveying equipment, which plays an important role in agricultural production. It is mainly used for conveying grains and oilseeds such as wheat, corn, soybeans, and rapeseed. The grain conveying auger usually consists of a spiral shaft and a closed round tube shell. The spiral shaft is driven by a motor and runs in the round tube shell. The thrust generated by its rotation realizes the conveying of materials. The grain conveying auger has the advantages of compact structure, easy operation, and high conveying efficiency.

[0003] During the working process of the grain conveying auger, the grains, i.e. materials, are pushed from one end of the round tube shell to the other end mainly by the rotation of the screw shaft. During the material conveying process, due to the nature of the conveyed grains or the aging and wear of the screw shaft, when conveying different grains, the discharge port of the round tube shell may be clogged with materials. Since the discharge port of the round tube shell is usually an integrated closed structure, it is not convenient to timely and effectively perform the maintenance of the screw shaft when the material is clogged inside the round tube shell.

[0038] Continue to refer to Figure 2 and Figure 3 The screw shaft 2 includes a screw conveying section 201 and a discharge connection section 202. One end of the screw conveying section 201 is passed through and rotatably mounted on the conveying shell 101. The outer peripheral surface of the screw conveying section 201 has a screw blade 8, so that the screw conveying section 201 drives the rotation of the screw blade 8 to realize the conveying of the boring in the conveying shell 101. One end of the discharge connection section 202 is rotatably connected to the discharge shell 102, and the other end is detachably connected to the screw conveying section 201. Specifically, the screw conveying section 201 is provided with a coaxial connection groove 9 extending along its own axis direction toward one end of the discharge connection section 202. The discharge connecting section 202 includes a discharge plug-in portion 2021 and a discharge fixing portion 2022 fixedly connected to one end of the discharge plug-in portion 2021. The discharge plug-in portion 2021 is plugged into the connecting groove 9. The cross-sectional size of the discharge fixing portion 2022 is larger than the cross-sectional size of the discharge plug-in portion 2021. When the discharge plug-in portion 2021 is plugged into the connecting groove 9, the end of the spiral conveying section 201 contacts the discharge fixing portion 2022 to achieve the positioning of the discharge connecting section 202 in the axial direction.

[0039] Reference Figure 3In order to facilitate the positioning of the discharge connecting section 202 in the circumferential direction, a positioning bar 10 is fixedly connected to one end of the discharge fixing portion 2022 close to the discharge plug-in portion 2021, and a positioning groove 11 corresponding to the position of the positioning bar 10 and plugged into the positioning bar 10 is opened at one end of the spiral conveying section 201 toward the discharge connecting section 202, so as to limit the rotation of the discharge connecting section 202 through the cooperation of the positioning bar 10 and the positioning groove 11.

[0040] Reference Figure 2 and Figure 3 The outer circumferential surface of the spiral conveying section 201 is provided with positioning holes 12 connected to the connecting groove 9. In the embodiment of the present application, there are two groups of positioning holes 12 distributed along the axis of the spiral conveying section 201, and each group of positioning holes 12 is evenly distributed circumferentially around the axis of the spiral conveying section 201. The discharge connecting section 202 is provided with connecting holes 13 that are the same in number as the fixing holes and are arranged one by one. A positioning piece 14 is arranged in each connecting hole 13, and the discharge connecting section 202 is provided with a positioning drive member that allows the positioning piece 14 to pass through or be received in the connecting hole 13.

[0041] Reference Figure 3 Specifically, in the embodiment of the present application, the positioning member 14 is a rod-shaped structure, and the positioning member 14 is inserted and slidably matched with the connecting hole 13. The positioning drive member includes a positioning drive rod 15, a positioning ring 16, a positioning stopper 17, and a positioning connecting rod 18, wherein the positioning drive rod 15 is coaxially rotatably installed on the discharge connecting section 202, and one end of the positioning drive rod 15 is inserted through the end of the discharge connecting section 202 away from the spiral conveying section 201 and is fixedly connected with a positioning rotating plate 19, so that the positioning drive rod 15 can be rotated by applying force through the positioning rotating plate 19.

[0042] Continue to refer to Figure 3 The positioning ring 16 is sleeved and threadedly engaged with the outside of the positioning drive rod 15, and the positioning limit piece 17 is used to limit the rotation of the positioning ring 16. Specifically, in the embodiment of the present application, the positioning limit piece 17 includes a limit pin, and the outer peripheral surface of the positioning ring 16 is provided with a receiving hole 20, and the limit pin is inserted into the receiving hole 20. The groove wall of the connecting groove 9 is provided with a limit slide groove 21 extending along the length direction of the discharge connecting section 202, and the limit pin is slidably engaged in the limit slide groove 21 to play a limiting role in the circumferential rotation of the positioning ring 16.

[0043] Reference Figure 2 and Figure 3There are two positioning rings 16 and positioning limit members 17 corresponding to the two groups of positioning holes 12, and two groups of positioning connecting rods 18 and positioning members 14 are correspondingly provided. Each group of positioning connecting rods 18 and positioning members 14 is provided with multiple positioning connecting rods 18 corresponding to each other. One end of each positioning connecting rod 18 is rotatably connected to the positioning ring 16 and the other end is rotatably connected to the positioning member 14, so that when the positioning drive rod 15 is rotated by applying force through the positioning rotating plate 19, the positioning ring 16 is matched with the thread of the positioning drive rod 15 and slides along the length direction of the positioning drive rod 15 under the limiting action of the positioning limit pin, thereby allowing the positioning connecting rod 18 to drive each positioning member 14 to slide in the connecting hole 13. When the positioning member 14 is inserted into or out of the fixing hole, the connection or disconnection between the spiral conveying section 201 and the discharging connecting section 202 is realized. The thread self-locking effect between the positioning ring 16 and the positioning driving rod 15 is conducive to fully ensuring the stability of the relative position of the spiral conveying section 201 and the discharging connecting section 202 after connection.

[0044] Reference Figure 1 and Figure 2 Furthermore, the motor 3 drives the spiral shaft 2 to rotate through a transmission mechanism, wherein the transmission mechanism includes a reducer 22, a driving wheel 23, a driven wheel 24, a synchronous belt 25 and an adjustment component. The output end of the motor 3 is installed at the input end of the reducer 22, and the driving wheel 23 is installed at the output end of the reducer 22, so that the motor 3 drives the driving wheel 23 to rotate through the reducer 22, thereby ensuring high torque and low speed operation of the driving wheel 23. The motor 3, the reducer 22 and the driving wheel 23 are all located at the bottom of the shell 1.

[0045] Reference Figure 2 One end of the spiral conveying section 201 is passed through the end of the conveying shell 101 away from the discharge shell 102, and the driven wheel 24 is coaxially fixedly installed on the end of the spiral conveying section 201 passing through the conveying shell 101. The synchronous belt 25 is wound around the outer circumference of the driving wheel 23 and the driven wheel 24, so that when the driving wheel 23 rotates, the spiral conveying section 201 is driven to rotate synchronously through the synchronous belt 25 and the driven wheel 24. The adjustment component is used to adjust the distance between the driving wheel 23 and the driven wheel 24.

[0046] Reference Figure 1 and Figure 2Specifically, the adjustment assembly includes an adjustment fixing plate 26, an adjustment screw 27, an adjustment nut 28, a first fixing nut 29 and a second fixing nut 30, wherein two adjustment fixing plates 26 are provided and are fixedly mounted on the bottom of the conveying shell 101 of the shell 1. There are four adjustment screws 27 distributed in a rectangular shape and are respectively arranged on the two adjustment fixing plates 26, and a reduction mounting plate 31 is fixedly mounted on the top of the reducer 22. Each adjustment screw 27 is sequentially passed through the adjustment fixing plate 26 and the reduction mounting plate 31 on the top of the reducer 22, and the adjustment nut 28 is threadedly matched with the reduction mounting plate 31. The adjustment nut 28, the first fixing nut 29 and the second fixing nut 30 are all threadedly matched with the adjustment screw 27 and are sequentially distributed from bottom to top, wherein the second fixing nut 30 is screwed so that the second fixing nut 30 is pressed against the bottom of the adjustment fixing plate 26 to achieve the desired effect. Now, the position of the adjusting screw 27 is firmly fixed, and the speed reduction mounting plate 31 is located between the adjusting nut 28 and the first fixing nut 29. By screwing the adjusting nut 28 and the first fixing nut 29 to respectively press the two sides of the speed reduction mounting plate 31 at different positions, the speed reducer 22 and the driving wheel 23 can be fixed at different height positions, which is convenient and fast. By adjusting the distance between the driving wheel 23 and the driven wheel 24, it is beneficial to stably adjust the tension of the synchronous belt 25, and then it is beneficial to ensure the driving stability when the motor 3 drives the spiral conveying section 201, that is, the spiral shaft 2 to rotate.

[0047] The implementation principle of an auger for conveying grains in an embodiment of the present application is as follows: when it is necessary to convey materials, the materials are first placed in the shell 1 through the feed hopper 4, and the motor 3 drives the screw shaft 2 to rotate so as to convey the materials in the shell 1, and the conveyed materials are finally discharged through the discharge port 5. When material blockage occurs in the shell 1, the discharge shell 102 is removed from the conveying shell 101, and the positioning drive rod 15 is rotated to make each positioning member 14 disengage from the fixing hole, thereby releasing the fixation between the discharge connecting section 202 and the spiral conveying section 201, thereby facilitating the rapid elimination of material blockage, and timely and effective inspection and maintenance of the spiral conveying section 201 can reduce the probability of subsequent material blockage.

[0048] Example 2.

[0049] Reference Figure 4 and Figure 5The main difference between the embodiment of the present application and the embodiment 1 is that the specific structures of the positioning member 14 and the positioning drive member are different. In the embodiment of the present application, the positioning member 14 includes a positioning ball 141, and the diameter of the positioning ball 141 is larger than the diameter at the opening of the connecting hole 13, so that the positioning ball 141 can pass through the connecting hole 13 and penetrate into the positioning hole 12 to achieve the fixation between the spiral conveying section 201 and the discharge connecting section 202. The positioning drive member includes a positioning slide rod 32 and a positioning spring 33. One end of the discharge connecting section 202 is provided with a positioning slide groove 34 that is arranged along its own axis. The connecting hole 13 is connected to the positioning slide groove 34. Specifically, the positioning slide groove 34 includes a first sliding section 341, a second sliding section 342 and a third sliding section 343 that are arranged in sequence. The second sliding section 342 is smaller than the diameter of the first sliding section 341 and the third sliding section 343.

[0050] Continue to refer to Figure 4 and Figure 5 The positioning slide bar 32 includes a positioning pressing portion 321, a positioning sliding portion 322 and a positioning accommodating portion 323 which are fixedly connected in sequence, wherein the positioning pressing portion 321, the positioning sliding portion 322 and the positioning accommodating portion 323 are slidably fitted in the first sliding section 341, the second sliding section 342 and the third sliding section 343 respectively, and the outer circumferential surface of the third sliding section 343 is provided with a positioning accommodating groove 35 for accommodating the positioning ball 141, the positioning spring 33 is sleeved on the outside of the positioning sliding portion 322, and one end of the positioning spring 33 is connected to the groove wall of the first sliding section 341 close to the second sliding section 342, and the other end is connected to the positioning pressing portion 321, so that the positioning slide bar 32 moves in the direction away from the discharge connecting section 202 under the elastic force of the positioning spring 33, and in normal state, the positioning ball 141 is passed through the outside of the connecting hole 13 and is clamped in the positioning hole 12 to achieve fixation between the spiral conveying section 201 and the discharge connecting section 202. In order to facilitate the positioning ball 141 to slide into or out of the positioning hole 12 , the groove walls of the positioning accommodating groove 35 close to both ends of the discharge connecting section 202 are provided with guiding inclined surfaces 36 to facilitate the driving of the positioning ball 141 .

[0051] The implementation principle of the auger for grain conveying in the embodiment of the present application is the same as that of the embodiment 1, and the main difference is that when releasing the fixation between the discharge connection section 202 and the spiral conveying section 201, the positioning slide bar 32 is pressed, and when the positioning groove 35 corresponds to the position of the positioning ball 141, the positioning groove 35 can accommodate the positioning ball 141, and at this time, the connection between the spiral conveying section 201 and the discharge connection section 202 can be released by applying force to move the discharge connection section 202. By pressing the positioning slide bar 32, the positioning ball 141 can be easily inserted into or separated from the positioning hole 12 to realize the fixation or non-fixation between the spiral conveying section 201 and the discharge connection section 202, which is convenient and fast.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
