DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0027] Please refer to Figures 1-7, the grain hulling waste temporary storage bin comprises a storage bin 1, a discharging assembly, a hammering assembly 3 and a speed reducer 4, the storage bin 1 is fixed vertically in a cylindrical shape, the bottom of the storage bin 1 is provided in a conical structure, the discharging assembly is installed on the inner side of the bottom of the storage bin 1 in a matched mode, the hammering assembly 3 comprises multiple groups of components installed on the outer side of the top of the storage bin 1 in a matched mode, and the speed reducer 4 is fixedly installed on the top of the storage bin 1 and is linked with the discharging assembly and the hammering assembly 3 through a transmission assembly; the discharging assembly comprises a mounting shaft A21, a spiral strip 22 and a connecting rod 23, the mounting shaft A21 is rotatably installed in the storage bin 1 and is linked with the speed reducer 4, the spiral strip 22 comprises multiple groups of components arranged in an annular array, the spiral strip 22 is fixedly connected to the bottom of the mounting shaft A21 through the connecting rod 23, and the spiral strip 22 is kept in close contact with the inner wall of the bottom of the storage bin 1.

[0028] The structural design of the storage bin 1 can ensure that the grain hulling waste is quickly injected into the storage bin 1 and is quickly output under the cooperation of the discharging assembly and the hammering assembly 3. When the speed reducer 4 works, the discharging assembly and the hammering assembly 3 are driven to run synchronously through the transmission assembly, the discharging assembly can quickly discharge the grain hulling waste accumulated at the bottom of the storage bin 1, ensuring the smoothness of the discharge of the grain hulling waste, and the hammering assembly 3 can shake off the grain hulling waste that is damp, caked and adhered to the inner wall of the storage bin 1, ensuring that the grain hulling waste can be completely discharged from the storage bin 1 and ensuring the cleanliness of the inner wall of the storage bin 1.

[0029] The spiral strip 22 needs to be in close contact with the inner wall of the storage bin 1 and rotate under the driving action of the speed reducer 4 and the mounting shaft A21, and the wear resistance of the spiral strip 22 needs to be ensured, therefore the spiral strip 22 comprises an iron base material and a wear-resistant strip fixed to the iron base material and kept in close contact with the inner wall of the storage bin 1.

[0030] Since the bottom of the storage bin 1 is provided in a conical structure, the grain hulling waste stored therein can be quickly discharged from the bottom, therefore the specific structural shape of the spiral strip 22 is a spiral strip 22 with a large top radius and a small bottom radius, which can be stably in close contact with the inner wall of the bottom conical storage bin 1.

[0031] In order to ensure that the mounting shaft A21 can be stably installed in the storage bin 1 in a relatively rotating mode, a mounting bracket 24 is fixedly connected to the inner side of the bottom of the storage bin 1, and the bottom of the mounting shaft A21 is rotatably installed on the mounting bracket 24.

[0032] Due to the bottom of the storage bin 1 is set as a tapered structure, the grain hulling waste accumulated at the bottom of the storage bin 1 is subjected to the gravity of the upper waste, and part of the waste is adhered to the tapered structure at the bottom. At the same time, due to the tapered structure has a smaller cross-sectional area from top to bottom, the accumulated grain hulling waste is difficult to be discharged quickly. When the speed reducer 4 is working to drive the discharge assembly to operate, the spiral strip 22 can scrape off the waste adhered to the inner wall of the tapered structure. At the same time, the structure and operating state of the spiral strip 22 are similar to those of the screw conveyor, which can exert a force on the grain hulling waste accumulated at the bottom of the storage bin 1 to quickly discharge the hulling waste.

[0033] In order to ensure the strength of the storage bin 1 to meet the stable strength of the grain hulling waste therein, ensure the normal input and discharge of the hulling waste in the storage bin 1, and ensure the stable installation of the speed reducer 4, the discharge assembly and the hammer assembly 3 on the storage bin 1, the following technical solutions are provided.

[0034] The top end of the storage bin 1 is fixedly connected with a mounting top plate 11, the lower surface of the mounting top plate 11 is fixedly connected with a mounting ring 12 arranged on the periphery of the storage bin 1, the mounting top plate 11 is fixedly installed with a feed hopper 13 in communication with the storage bin 1, the speed reducer 4 is fixedly installed on the mounting top plate 11, the mounting shaft A21 is rotatably installed on the mounting top plate 11, and the hammer assembly 3 is installed on the inner side of the mounting ring 12; the middle section of the storage bin 1 is fixedly connected with a reinforcing ring 14, and the bottom of the storage bin 1 is fixedly connected with an on-off valve.

[0035] The mounting top plate 11 and the mounting ring 12 arranged thereon can ensure the stable installation of the speed reducer 4, the hammer assembly 3 and the mounting shaft A21 of the discharge assembly on the storage bin 1, and the reinforcing ring 14 can improve the strength of the storage bin 1 to ensure the stability thereof when storing the grain hulling waste.

[0036] The grain hulling waste can be injected into the storage bin 1 through the feed hopper 13 at the top of the storage bin 1 for temporary storage, and the discharge of the grain hulling waste can be controlled by opening the on-off valve at the bottom of the storage bin 1.

[0037] As an embodiment for facilitating the maintenance and cleaning of the storage bin 1, the mounting top plate 11 can be installed on the top of the storage bin 1 by means of bolt fixation, which facilitates the disassembly and assembly of the mounting top plate 11. After the mounting top plate 11 is removed, the installation, maintenance and cleaning of the discharge assembly installed in the storage bin 1 can be facilitated.

[0038] In order to ensure that the hammer assembly 3 can effectively act on the storage bin 1 and ensure that the hammer assembly 3 is stably installed between the storage bin 1 and the mounting ring 12, the following technical solutions are provided.

[0039] The hammering assembly 3 comprises a guide sliding groove 31, a sliding seat 32, a hammer head 33, a cushion seat 34, a return spring 35, a transmission rack 36, and a sector gear 37. The guide sliding groove 31 is fixedly installed on the inner wall of the mounting ring 12. The cushion seat 34 is fixedly installed on the outer wall of the storage bin 1 and is arranged opposite to the guide sliding groove 31. The sliding seat 32 is slidingly installed on the guide sliding groove 31. The return spring 35 is arranged in the guide sliding groove 31 and is fixedly connected at both ends to the inner wall of the mounting ring 12 and the sliding seat 32, respectively. The transmission rack 36 and the hammer head 33 are both fixedly connected to the sliding seat 32, and the hammer head 33 abuts against the cushion seat 34. The sector gear 37 is rotatably installed on the mounting top plate 11 and is linked with the reduction motor 4, and the sector gear 37 is in engagement with the transmission rack 36.

[0040] When the reduction motor 4 drives the sector gear 37 to rotate, the transmission rack 36 and the sliding seat 32 and the hammer head 33 fixedly combined with the transmission rack 36 are driven to move towards the inside of the guide sliding groove 31, at this time, the return spring 35 is compressed and stores elastic potential energy. When the gap position of the sector gear 37 rotates to one side of the transmission rack 36, the sector gear 37 cancels the engagement with the transmission rack 36, at this time, the return spring 35 can normally release the elastic potential energy and the sliding seat 32 and the transmission rack 36 and the hammer head 33 thereon are ejected, so that the hammer head 33 strikes the cushion seat 34, and the vibration generated by the striking is transmitted to the storage bin 1 to shake off the adhered grain hulling waste thereon. After that, the sector gear 37 further rotates, and the teeth thereon re-act with the transmission rack 36 to enter the next vibration work.

[0041] Since the hammering assembly 3 comprises multiple groups arranged in an annular array, the vibration generated by the simultaneous operation of each group of the hammering assembly 3 can be uniformly transmitted to the inner wall of the storage bin 1, and the adhered grain hulling waste is effectively shaken off.

[0042] In order to ensure that each group of the hammering assembly 3 can be synchronously operated under the driving of the reduction motor 4 and to ensure that the sector gear 37 is stably installed on the mounting top plate 11, the following technical solutions are provided.

[0043] The hammering assembly 3 further comprises a connecting shaft 38 and a synchronous wheel 39. The connecting shaft 38 is rotatably installed on the mounting top plate 11. The sector gear 37 and the synchronous wheel 39 are both fixedly installed on the connecting shaft 38. A synchronous belt 310 is wound on the synchronous wheel 39 in each group of the hammering assembly 3 and is in a tight state.

[0044] The connecting shaft 38 is fixedly combined with the sector gear 37 and the synchronous wheel 39, and is in engagement with each synchronous wheel 39 through the synchronous belt 310, so as to realize the synchronous operation of each sector gear 37. When the reduction motor 4 drives one group of the hammering assembly 3 to operate, the remaining groups can be synchronously driven to operate.

[0045] To avoid the motion interference between the connecting shaft 38 and the corresponding running slide 32, a strip-shaped guide groove is formed on the slide 32, and the bottom end of the connecting shaft 38 is arranged in the strip-shaped guide groove.

[0046] To ensure that the reduction motor 4 can drive the vibration hammer assembly 3 and the discharge assembly to run stably through the synchronous belt 310, the following technical solutions are provided.

[0047] The transmission assembly includes a mounting shaft B51, a first drive gear 52, a second drive gear 53, a first transmission gear 54, and a second transmission gear 55. The mounting shaft B51 is rotatably mounted above the mounting top plate 11 and fixedly combined with the rotating shaft of the reduction motor 4. The first drive gear 52 and the second drive gear 53 are fixedly mounted on the mounting shaft B51. The first transmission gear 54 is fixedly mounted on the top end of the mounting shaft A21 and engaged with the first drive gear 52. The top end of one set of the connecting shaft 38 of the vibration hammer assembly 3 is fixedly connected with the second transmission gear 55, and the second transmission gear 55 is engaged with the second drive gear 53.

[0048] To cooperate with the installation of the reduction motor 4 and stably transmit power to the mounting shaft 21 and the connecting shaft 38, the first drive gear 52, the second drive gear 53, the first transmission gear 54, and the second transmission gear 55 all adopt bevel gears.

[0049] When the reduction motor 4 drives the mounting shaft B51 and the first drive gear 52 and the second drive gear 53 on it to rotate, power can be transmitted to the first transmission gear 54 and the second transmission gear 55, respectively. The rotation of the first transmission gear 54 drives the mounting shaft A21 and the spiral strip 22 fixedly connected thereto to run effectively, thereby realizing the function of the discharge assembly. The rotation of the second transmission gear 55 drives the connecting shaft 38 fixedly connected thereto to rotate stably, thereby driving the vibration hammer assembly 3 to run synchronously through the combination of the synchronous belt 310 and the synchronous wheel 39, thereby realizing the function of the vibration hammer assembly 3.

[0050] Since the storage bin 1 is usually installed outdoors, if the on-off valve at the bottom of the storage bin 1 is controlled by electricity or hydraulic pressure, it is prone to malfunction in cold winter or rainy and snowy weather. To ensure the stability of the on-off valve, a mechanical control scheme is selected, and the following technical solutions for the on-off valve are provided.

[0051] The bottom of the storage bin 1 is communicated with a discharge pipe 15, and a switch valve is matched with the discharge pipe 15, and the switch valve comprises a mounting cover 161, a trapping plate 162, a sliding block 163, an adjusting screw 164 and a driving wheel 165, the mounting cover 161 is fixedly installed on the discharge pipe 15, a sliding groove 166 is formed in the mounting cover 161, the sliding block 163 is slidingly installed in the sliding groove 166, the trapping plate 162 is fixedly connected with the sliding block 163 and extends into the inner side of the discharge pipe 15, the inner side end of the adjusting screw 164 is rotatably installed on the sliding block 163, the adjusting screw 164 is rotatably connected with the mounting cover 161, and the driving wheel 165 is fixedly connected with the outer side end of the adjusting screw 164 and is arranged outside the mounting cover 161.

[0052] When the driving wheel 165 is rotated to drive the adjusting screw 164 to rotate, the adjusting screw 164 can move relative to the mounting cover 161, thereby driving the sliding block 163 and the trapping plate 162 to slidingly extend and retract in the sliding groove 166, so as to control the plugging state of the trapping plate 162 to the discharge pipe 15 and control the discharge of the shelling waste of the grain, and the switch valve is designed as a mechanical type, which has better stability than an electric control type and a hydraulic type, and has very low maintenance cost and maintenance frequency.

[0053] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended to encompass all changes falling within the meaning and scope of the equivalent elements of the claims. Any reference signs in the claims should not be considered as limiting the claims involved.
