Description

Technical Field

[0001] This application belongs to the technical field of filling equipment for storage devices, and particularly relates to a grain feeder with multiple crushing standard sections. Background Technology

[0002] The silo is an important piece of equipment for grain storage. Because of its height, if the grain falls directly into the silo, it will be very easy to break and segment it, which will affect the quality of the stored grain. Therefore, the grain feeder is crucial for preventing grain segmentation and reducing breakage.

[0003] Currently, grain feeders have many structures, such as feeders with a central discharge pipe, but feeders with a central discharge pipe have the following problems:

[0004] 1. Some central unloading pipes lack a core buffer, resulting in poor grain anti-grading and anti-breakage effects. Each section of the central unloading pipe has a grain outlet, leading to serious grain spillage.

[0005] 2. Some central unloading pipes only have a buffer structure, and the effect of preventing grain grading and reducing breakage needs to be improved;

[0006] 3. The radial overflow distribution pipe is always open, so the grain cannot be concentrated into the central unloading pipe, causing the grain to enter the radial overflow distribution pipe in advance. Utility Model Content

[0007] In order to solve the above problems, this application provides a grain feeder with multiple crushing standard sections.

[0008] The purpose of this application is to provide a grain feeder with multiple crushing standard sections. Under the combined action of the crushing sections and airflow, the grain is mixed more evenly and falls more slowly during the falling process, thereby achieving the purpose of preventing grading and reducing breakage.

[0009] To achieve the purpose of this application, the technical solution of this application is as follows:

[0010] A grain feeder with multiple crushing standard sections includes a central discharge pipe, a maintenance section at the lower end of the central discharge pipe, and multiple crushing standard sections on the maintenance section. Each crushing standard section includes a standard section and crushing sections arranged above the standard section. The crushing sections include perforated crushing sections and non-perforated crushing sections. The perforated crushing sections are arranged in the middle and lower sections of the central discharge pipe, and the non-perforated crushing sections are arranged in the upper section of the central discharge pipe. An overflow buffer and a flow guide buffer are arranged inside the crushing sections. The overflow buffer is arranged above the flow guide buffer. An upper air distribution box is provided at the upper end of the central discharge pipe, and a lower air distribution box is provided at the lower end of the central discharge pipe. The upper air distribution box is connected to a circulating fumigation machine through a fumigation pipe, and the upper air distribution box is connected to a central ventilator through a ventilation pipe. The central discharge pipe includes a ventilation duct arranged on the outer side, and the upper and lower air distribution boxes are connected to the ventilation duct.

[0011] Furthermore, the lower air distribution box is equipped with a ventilation duct pipe, a return air pipe, and a dual-purpose pipe. The ventilation duct pipe connects to the ventilation cylinder and the ventilation duct, while the return air pipe and the dual-purpose pipe connect to the central pipe in the central unloading pipe.

[0012] Furthermore, a cylinder cage is installed at the upper end of the upper air box, and a maintenance manhole is provided on the cylinder cage.

[0013] Furthermore, a material collection hopper is installed inside the upper air collection box, and a valley cooling return air outlet is installed on the upper air collection box.

[0014] Furthermore, a central tube for the material distributor is installed inside the hopper, a material flow converter is installed at the lower end of the central tube, a pneumatic gate is installed at the lower end of the material flow converter, and a discharge pipe is installed at the lower end of the pneumatic gate. The discharge pipe is arranged above the collection hopper.

[0015] Furthermore, the central tube of the material distributor is equipped with multiple mounting joints, each with a chute, and a pneumatic flap valve is installed on the central tube of the material distributor, with the pneumatic flap valve located inside the mounting joint.

[0016] Furthermore, the cage is equipped with bracing, and the ends of the bracing are connected to the chute.

[0017] Furthermore, a discharge port is provided inside the chute, and a pneumatic valve is installed on the discharge port.

[0018] Furthermore, the end of the chute is equipped with a lifting lug, and a lifting chain is installed on the lifting lug. The upper end of the lifting chain is fixed to the hopper.

[0019] Furthermore, the overflow buffer includes a bucket-shaped buffer, and the flow guide buffer includes a buffer bucket arranged at the upper end and a ventilation bucket arranged at the lower end, with ventilation holes provided on the ventilation bucket.

[0020] Compared with the prior art, the beneficial effects of this application are as follows:

[0021] 1. This application has a central unloading pipe. This application mainly uses a central unloading pipe with multiple crushing reduction standard sections to achieve crushing reduction unloading of grain, rather than mainly using radial overflow distribution pipes to achieve unloading. When the grain flows along the central unloading pipe, under the dual action of the crushing reduction section and airflow, the grain is more evenly mixed and the falling speed is slower during the falling process, so as to achieve the purpose of preventing grading and reducing crushing.

[0022] 2. This application utilizes a central unloading pipe in conjunction with a radial overflow distribution pipe. The central unloading pipe completes the unloading and distribution of grain in the middle and lower sections, while the radial overflow distribution pipe completes the unloading and distribution of grain in the upper section. During unloading and distribution in the central unloading pipe, the radial overflow distribution pipe is closed to allow the central unloading pipe to discharge material smoothly. After the central unloading pipe finishes unloading, it is closed, allowing the grain to flow out from the radial overflow distribution pipe, reducing the falling distance of the grain and minimizing grain breakage.

[0023] 3. This application arranges an overflow buffer and a flow guide buffer in the crushing section, so that the grain first passes through the overflow buffer, and under the buffering effect of the overflow buffer, the grain slows down and mixes, and then enters the flow guide buffer. Under the flow guide and ventilation effect of the flow guide buffer, the grain slows down and mixes again, so as to achieve the purpose of preventing grading and reducing breakage.

[0024] 4. This application arranges a ventilation duct on the central unloading pipe, which can be filled with nitrogen, dry cold air, dry air, etc., to provide a longer storage time for grain. Attached Figure Description

[0039] Example 1

[0040] This embodiment is a grain feeder with multiple crushing reduction standard sections, installed inside a grain storage silo. The grain feeder includes a central discharge pipe for discharging grain from the lower middle section of the silo. A maintenance section 2 is installed at the lower end of the central discharge pipe, connected to the central discharge pipe via flanges and bolts. As a core structure, the maintenance section 2 in this embodiment has multiple crushing reduction standard sections 3 installed on it. Each crushing reduction standard section 3 includes a standard section 3 and crushing reduction sections arranged above it. The standard section 3 and the crushing reduction sections are connected together via flanges and bolts. The crushing reduction sections include perforated crushing reduction sections 4 and... The non-perforated crushing reduction section 5 and the perforated crushing reduction section 4 are arranged in the middle and lower sections of the central unloading pipe. The non-perforated crushing reduction section 5 is arranged in the upper section of the central unloading pipe. The perforated crushing reduction section 4 has a grain outlet, and the grain flows out from the perforated crushing reduction section 4 along the grain outlet. For example, in this embodiment, seven crushing reduction standard sections 3 are installed at the upper end of the maintenance section 2. The lowest crushing reduction standard section 3 includes one standard section 3 and one crushing section. The remaining six crushing reduction standard sections 3 include two standard sections 3 and one crushing section. The uppermost two crushing reduction standard sections 3 are non-perforated crushing reduction sections 5, and the rest are perforated crushing reduction sections 4.

[0041] In this embodiment, an overflow buffer 28 and a flow guide buffer 29 are installed in the crushing section. The overflow buffer 28 is arranged above the flow guide buffer 29. The overflow buffer 28 includes a bucket-shaped buffer, and an overflow pipe is installed on the side wall of the bucket-shaped buffer. In this embodiment, the overflow pipe is a horizontal pipe. After the grain enters the bucket-shaped buffer, the grain moves slowly in the narrow bucket-shaped buffer. Some grain is pushed into the overflow pipe and slowly descends. Some grain flows out slowly from the lower end of the bucket-shaped buffer, and some grain flows out from the upper end of the bucket-shaped buffer, realizing the slow flow of grain. The flow guide buffer 29 includes a buffer bucket arranged at the upper end and a ventilation bucket arranged at the lower end. The ventilation bucket has ventilation holes with an opening ratio of not less than 30%. The grain flowing out of the overflow buffer 28 enters the flow guide buffer 29 and bounces. The airflow enters the flow guide buffer 29 from the ventilation holes, which slows down the grain and prevents or reduces the grading of the grain.

[0042] In this embodiment, an upper air collection box 7 is installed at the upper end of the central unloading pipe. Two standard sections 3 are installed on the uppermost crushing standard section 3 and connected to the upper air collection box 7. A lower air collection box 1 is installed at the lower end of the central unloading pipe. The upper air collection box 7 is connected to the circulating fumigation machine 19 through the fumigation pipe 15. The upper air collection box 7 is connected to the central ventilator 20 through the ventilation pipe 17. Telescopic hoses 18 are installed on both the fumigation pipe 15 and the ventilation pipe 17.

[0043] In this embodiment, the central unloading pipe includes a ventilation duct 27 arranged on the outside. The upper air collecting box 7 and the lower air collecting box 1 are connected to the ventilation duct 27. The airflow entering from the upper air collecting box 7 will enter the lower air collecting box 1 and the interior of the central unloading pipe along the ventilation duct 27. Specifically, the lower air collecting box 1 is equipped with a ventilation ground channel pipe 24, a return air pipe 25, and a dual-purpose pipe 26. The ventilation ground channel pipe 24 connects the ventilation duct 27 and the ventilation ground channel. The airflow entering from the upper air collecting box 7 enters the ventilation ground channel along the ventilation duct 27 and flows out of the hopper along the ventilation ground channel, forming a circulation. The return air pipe 25 and the dual-purpose pipe 26 are connected to the central pipe in the central unloading pipe. The dual-purpose pipe 26 can be connected to nitrogen or a valley cooling pipe.

[0044] In this embodiment, the upper air collecting box 7 is equipped with a material collecting hopper 6. The material collecting hopper 6 serves as the last material collection before entering the central unloading pipe, and has the purpose of collecting grain and slowing down the grain flow. The upper air collecting box 7 is equipped with a grain cooling return air inlet. A cylinder cage 9 is installed at the upper end of the upper air collecting box 7. A maintenance manhole 8 is provided on the cylinder cage 9. A sealing plate and a sealing gasket are installed on the maintenance manhole 8. That is, the maintenance manhole 8 is an important maintenance component at the upper end of the grain distributor in this embodiment. The important maintenance component at the lower end of the grain distributor is the maintenance section 2. A maintenance door is installed on the maintenance section 2. A sealing plate and a sealing gasket are installed on the maintenance door.

[0045] A feeder center tube is installed inside the cage 9. A feeder converter 11 is installed at the lower end of the feeder center tube. The feeder converter 11 has several holes, but the diameter is smaller than the diameter of the grain. A pneumatic gate 10 is installed at the lower end of the feeder converter 11. A discharge pipe is installed at the lower end of the pneumatic gate 10. The discharge pipe is arranged above the collecting hopper 6. The grain is collected in the feeder converter 11 to achieve the purpose of slowing down the grain. In addition, the feeder converter 11 can be connected to a ventilation duct 17 to blow air into the feeder converter 11. In addition, in this embodiment, a vibrator can also be installed on the feeder converter 11 to ensure that the grain flows out smoothly from the feeder center tube.

[0046] In this embodiment, the central tube of the feeder is equipped with multiple mounting joints 16. As one implementation, there are six mounting joints 16 in this embodiment. A chute 13 is installed on the mounting joint 16. A pneumatic flap valve 12 is installed on the central tube of the feeder. The pneumatic flap valve 12 is arranged inside the mounting joint 16. By closing the pneumatic gate 10, grain is prevented from flowing out of the central tube of the feeder. By opening the pneumatic flap valve 12, grain will enter the chute 13 along the mounting joint 16. Multiple discharge ports are installed in the chute 13. Pneumatic valves 23 are installed on the discharge ports. In this embodiment, closing the pneumatic gate 10 closes the central discharge pipe. Opening the pneumatic flap valve 12 opens the chute 13. As grain continuously accumulates in the central tube of the feeder, grain flows into the chute 13. As grain fills the chute 13, the pneumatic valve 23 is opened, allowing grain to flow out from the discharge port.

[0047] As a fixing scheme for the radial overflow distribution pipe, this embodiment has a brace 14 installed on the hopper 9. The head end of the brace 14 is fixed to the central tube of the distributor, and the end of the brace 14 is connected to the chute 13, so that the brace 14 and the chute 13 are fixed together. The fixing position is located in the middle section of the chute 13. The end of the chute 13 is equipped with a lifting lug 21, and a lifting chain 22 is installed on the lifting lug 21. The upper end of the lifting chain 22 is fixed to the hopper. In this embodiment, the front section of the chute 13 is fixed by the mounting joint 16, the middle section of the chute 13 is fixed by the brace 14, and the rear section of the chute 13 is fixed by the lifting chain 22. If the chute 13 is fixed entirely by the lifting chain 22, the chute 13 will easily shake when impacted by grain. This embodiment can reduce the impact of grain on the chute 13, so that the grain feeding is stable. After the grain is fed, the hopper is leveled.
