The grain conveying means is provided with a rotary feeder at the lower end of the outlet of the hopper and a blower tube is installed at the vertical lower end of the discharge tube of the rotary feeder in a horizontal direction so that the grain falling from the hopper is discharged to the lower discharge port by the rotary feeder. It is transferred by the wind pressure of.

② 또 다른 곡물 이송수단으로는 특허원 98-43120호가 있으며 이 곡물 이송장치는 도 1에 표시된 바와 같이 홉퍼(H)의 하단부에 로터리 피더(F)가 설치되고 홉퍼(H)의 중간내부에 여과망(M)이 설치되며 그 측방에 진공펌프의 흡입구(D)가 형성되어 모터(M)와 감속기(C)에 의하여 진공펌프(V)와 로터리 피더(F)의 밴(b)을 동시적으로 구동하면 진공펌프(V)에 의하여 흡입된 곡류가 홉퍼(H)의 여과망(M)에서 유체와 분리되게 하고 홉퍼(H)에서 분리된 곡류는 로터리 피더(F)의 흡입구(I)를 통하여 밴(b)에 의하여 토출구(U)로 토출되면 상기 진공펌프(V)의 송풍압에 의하여 외부로 이송하게 되어 있다.② Another grain conveying means is Patent Application No. 98-43120, the grain conveying device is a rotary feeder (F) is installed at the lower end of the hopper (H) as shown in Figure 1 and the filtering network in the middle of the hopper (H) (M) is installed and the suction port (D) of the vacuum pump is formed on the side thereof, and the van (b) of the vacuum pump (V) and the rotary feeder (F) by the motor (M) and the reducer (C) simultaneously. When driven, the grains sucked by the vacuum pump (V) are separated from the fluid in the filter network (M) of the hopper (H), and the grains separated from the hopper (H) are banned through the inlet (I) of the rotary feeder (F). When discharged to the discharge port U by (b), it is transferred to the outside by the blowing pressure of the vacuum pump (V).

상기 ①의 선행기술의 곡물 이송수단은 로터리 피더의 토출구의 수직 하방에 송풍관이 직각으로 교차되어 있기 때문에 송풍압력이 토출관으로 역류되어 회전되는 로터리 피더의 밴과 풍압에 의한 부디침으로 배출이 불량하고 곡류가 부서지는 등의 문제점이 있었다.The grain conveying means of the prior art of ① is discharged poorly due to the vane of the rotary feeder which is rotated by flowing back to the discharge pipe because the blower pipe crosses at right angles vertically below the discharge port of the rotary feeder. There was a problem such as broken grains.

상기 ②의 선행기술의 곡물 이송수단은 이전의 선행수단①에 비하여 곡류의 이송통로와 유체 통로 간에 충돌이 없는 이점이 있으나 로터리 피더의 상부에 홉퍼가 돌출되어 부피가 크고 운반 취급이 불편하며 사용이 거추장스러운 미비점이 있었다.The grain conveying means of the prior art of the above ② has the advantage that there is no collision between the conveying passage and the fluid passage of cereals as compared to the previous preceding means ①, but the hopper is protruded on the upper part of the rotary feeder, which is bulky and inconvenient to handle and use. There was a cumbersome flaw.

본 발명의 목적은 특히 상기 ①의 곡물 이송수단의 홉퍼를 생략하고 전체 구조를 보다 간소화하여 제작시의 생산 코스트를 절감하고 운반 취급이 간편하며 누구나 편리하게 각종 용도로 사용할 수 있는 입상물질의 이송 로터리 피더장치를 제공하려는데 있다.The purpose of the present invention is to omit the hopper of the grain conveying means of the above ① and to simplify the overall structure to reduce the production cost at the time of manufacturing, easy handling and transport of granular material that anyone can use for various purposes conveniently It is to provide a feeder device.

본 발명은 로터리 피더와 진공펌프가 결합되어 감속기를 가진 모터의 선단축에 의하여 진공펌프의 팬이 고속으로 회전되고 모터의 감소기 축에 의하여 로터리 벤이 회전하게 된 것에 있어서, 로터리 피더의 흡입구를 진공펌프의 흡입구가 되게하고 로터리 피더의 토출구가 진공펌프의 토출구가 되도록 진공펌프의 U형 유체통로 중간부에 가로질러 로터리 피더의 입상물질 통로가 구성되게 하며 로터리 피더의 하우징 일부에 여과망이 장착된 진공펌프의 흡입통로가 되게 구성하였다.According to the present invention, the rotary feeder and the vacuum pump are coupled to each other so that the fan of the vacuum pump is rotated at a high speed by the front end shaft of the motor having the speed reducer and the rotary ben is rotated by the reducer shaft of the motor. The granular material passage of the rotary feeder is formed across the middle of the U-shaped fluid passage of the vacuum pump so that the suction port of the vacuum pump is the discharge port of the vacuum pump, and the filtering net is mounted on a part of the housing of the rotary feeder. The suction passage of the vacuum pump was configured.

따라서 진공펌프의 유체통로는 로터리 피더의 흡입구와 토출구를 통하게 되고 로터리 피더의 입상물질의 통로는 상기 유체통로의 근접거리로 연결되어 진공펌프의 흡인력에 의하여 흡입된 곡류나 입상물질은 로터리 피더를 통하여 밴에 의하여 토출구로 토출되는 순간 진공팬의 송풍압력에 의하여 목적하는 장소로 이송된다.Therefore, the fluid passage of the vacuum pump passes through the suction port and the discharge port of the rotary feeder, and the passage of the granular material of the rotary feeder is connected to the proximal distance of the fluid passage, so that the grain or granular material sucked by the suction force of the vacuum pump passes through the rotary feeder. At the moment of being discharged to the discharge port by the van, it is transferred to the desired place by the blowing pressure of the vacuum fan.

또 로터리 피더와 진공펌프가 결합된 간단한 구조로 되어 있고 홉퍼의 구조가 생략되어 그만큼 제작에 따른 생산 코스트가 경제적으로 보다 절감되고 운반취급이 용이하여 곡물이나 각종 입상원료, 또는 입상물질 등을 이송하는데 누구나 보다 편리하게 사용할 수 있다.In addition, it has a simple structure that combines rotary feeder and vacuum pump, and the structure of the hopper is omitted so that the production cost is reduced more economically and the transportation and handling are easy. Anyone can use it more conveniently.

도 1은 본 발명의 구성을 보인 개략도이다.1 is a schematic view showing the configuration of the present invention.

진공펌프(1)와 로터리 피더(2)가 결합되어 감소기(3)를 가진 모터(4)의 회전축(4a)에 의하여 진공펌프(1)의 팬(1f)이 회전되고 감속기(3)의 회전축(4a)에 의하여 로터리 밴(2v)이 회전되게 구성되어 모터(4)의 동력으로 진공펌프(1)와 로터리 피더(2)가 동시적으로 가동하게 된 것에 있어서, 진공펌프(1)의 흡입관(1a)은 로터리 피더(2)의 상부 하우징(2h)에 형성된 통기공(2b)에 여과망(2m)과 함게 커버(1b)를 통하여 접속되어 로터리 피더(2)의 흡입관(2a)이 진공펌프의 흡입관을 겸하게 되어 있고 진공펌프(1)의 토출관(1c)은 로터리 피더(2)의 토출구(2c)와 직결되어 진공펌프의 토출구를 겸하게 되어 U형의 유체통로 중간부에 입상물체의 통로가 직결된 것이다.The fan 1f of the vacuum pump 1 is rotated by the rotary shaft 4a of the motor 4 having the reducer 3 by combining the vacuum pump 1 and the rotary feeder 2, The rotary van 2v is rotated by the rotation shaft 4a so that the vacuum pump 1 and the rotary feeder 2 are operated simultaneously by the power of the motor 4, so that the vacuum pump 1 The suction pipe 1a is connected to the vent hole 2b formed in the upper housing 2h of the rotary feeder 2 through the cover 1b together with the filter net 2m so that the suction pipe 2a of the rotary feeder 2 is vacuumed. It serves as the suction pipe of the pump, and the discharge pipe 1c of the vacuum pump 1 is directly connected to the discharge port 2c of the rotary feeder 2 to serve as the discharge port of the vacuum pump. The passage is directly connected.

이러한 구성으로 된 본 발명은 곡물의 이송이나 산업체에서 각종 입상(粒狀)원료나 입상물체를 이송하는데 사용한다.The present invention having such a configuration is used for conveying various granular raw materials or granular objects in grain conveyance or industrial use.

즉, 로터리 피더(2)의 흡입구(2a)는 곡류 등의 입상물체에 삽입한 흡입관에 연결하고 동 토출구(2c)는 이송관에 관접한 다음 모터(4)와 감속기(3)에 의하여 진공펌프(1)의 팬(1f)과 로터리 피더(2)의 밴(2v)을 동시에 구동한다.That is, the suction port 2a of the rotary feeder 2 is connected to the suction pipe inserted into the granular object such as grains, and the discharge port 2c is connected to the transfer pipe, and then the vacuum pump is driven by the motor 4 and the reducer 3. The fan 1f of (1) and the van 2v of the rotary feeder 2 are simultaneously driven.

진공펌프(1)의 가동에 의하여 부압이 된 로터리 피더(2)의 흡입구(2a)로 흡입되는 유체와 함께 입상물체가 흡입되어 로터리 피더(2)의 하우징 내부(2h)로 유입된다.The granular object is sucked into the housing 2h of the rotary feeder 2 together with the fluid sucked into the suction port 2a of the rotary feeder 2 which becomes negative pressure by the operation of the vacuum pump 1.

하우징(2h)내부로 유입된 곡류 등의 입상물체는 여과망(2m)에 의하여 유체와 분리되어 밴(2v)의 회전력에 의하여 로터리 펌프처럼 토출구(2c)로 토출되고 하우징(2h)에 유입된 유체는 통기공(2b)을 통하여 흡입관(1a) 및 진공펌프(1)의 팬(1f)을 거쳐 로터리 피더(2)의 토출구(2c)로 송풍된다.Granular objects such as grains introduced into the housing 2h are separated from the fluid by the filter net 2m and discharged to the discharge port 2c like a rotary pump by the rotational force of the van 2v and flowed into the housing 2h. Is blown to the discharge port 2c of the rotary feeder 2 via the suction pipe 1a and the fan 1f of the vacuum pump 1 through the vent hole 2b.

따라서 로터리 피더(2)의 토출구(2c)로 토출된 곡류는 송풍압력에 의하여 유체와 함께 이송관을 통하여 어느 한 위치에서 다른 위치로 이송되는 것이다.Therefore, the grains discharged to the discharge port 2c of the rotary feeder 2 are transferred from one position to another position through the transfer pipe together with the fluid by the blowing pressure.

로터리 피더와 진공펌프가 결합된 것에 있어서, 진공펌프의 흡입관 및 토출관을 로터리 피더의 흡입관 및 토출관으로 겸하게 구성하여 진공펌프의 흡입구와 흡입관, 진공펌프, 토출관 및 토출구를 연결하는 U형의 유체통로의 중간부에 로터리 피더의 흡입구와 로터리 피더 하우징 및 토출구를 연결하는 입상물질의 통로가 직결되게 형성하였기 때문에 진공펌프의 흡입력에 의하여 로터리 피더에 유입된 입상물체는 밴에 의하여 토출구로 토출되면서 진공펌프의 송풍압력으로 이송되므로 입상물체의 통로와 유체통로의 간섭이 없고 입상물질의 역류 형상이 없이 유체에너지의 이송효율이 보다 향상된다.In the rotary feeder and the vacuum pump combined, the suction and discharge tubes of the vacuum pump serve as the suction and discharge tubes of the rotary feeder to connect the suction and suction pipes of the vacuum pump, the vacuum pump, the discharge pipe and the discharge port. Since the passage of granular material connecting the inlet port of the rotary feeder, the rotary feeder housing and the outlet port is directly connected to the middle part of the fluid passage, the granular object introduced into the rotary feeder by the suction force of the vacuum pump is discharged to the outlet port by the van. Since it is conveyed by the blowing pressure of the vacuum pump, there is no interference between the passage of the granular object and the fluid passage, and the transfer efficiency of the fluid energy is improved without the reverse flow shape of the granular material.

또 종래의 홉퍼의 구조가 략되고 그만큼 생산 코스트가 경제적으로 절감되며운반 취급이 용이하고 각종 용도에 누구나 편리하게 사용할 수 있는 효과가 있다.In addition, the structure of the conventional hopper is shortened, the production cost is reduced economically by that, easy to handle handling and there is an effect that anyone can use conveniently in various applications.
