[0002] In order to prevent bulk grain from compacting in the silo, it is necessary to transfer the bulk grain to different silos from time to time. Bulk grain transfer devices are used between silos to achieve the transfer of bulk grain. During the bulk grain transfer process, the bulk grain needs to be measured for storage management.

[0003] With regard to the above-mentioned related technologies, during the transfer process of bulk grain, the material level in the transfer pipeline will change with the feed amount and feed speed. If the bulk grain discharge is always maintained at the same speed, it will affect the stability of subsequent work. Summary of the invention

[0004] In order to improve the discharging stability of a bulk grain transfer device, the present application provides a bulk grain transfer metering device with automatic material level control.

[0006] By adopting the above technical solution, the bulk grain enters the buffer chute through the feed pipe and is weighed by the chute scale. At the same time, the bulk grain level in the buffer chute is detected by the capacitive distance sensor, and the capacitive distance sensor transmits the bulk grain level signal to the controller, which controls the opening size of the gate component. It ensures that the bulk grain level is always maintained between the high material point and the low material point, and improves the discharge stability of the bulk grain transfer device.

[0007] Optionally, the gate assembly includes: Two first telescopic rods, the two first telescopic rod fixed ends are symmetrically and fixedly mounted on the discharge pipe, and the controller is electrically connected to the first telescopic rods; A sliding plate is slidably mounted on the discharge pipe and is fixedly connected to the movable end of the first telescopic rod.

When the gate assembly opening is reduced, the controller controls the movable end of the first telescopic rod to extend, and the movable end of the first telescopic rod drives the two sliding plates to move toward each other, thereby reducing the diameter of the discharge pipe opening and improving the discharge stability of the bulk grain transfer device. This prevents materials from accumulating in the buffer chute and on the chute scale, thereby affecting the metering accuracy of the chute scale.

[0009] Optionally, two groups of material shaking components are installed in the discharge pipe, and the two groups of material shaking components are respectively connected to the two sliding plates, and the two groups of material shaking components include: Two sliding rods, two of the sliding rods are inserted into the discharge pipe, two of the sliding rods are horizontally slidably mounted on the discharge pipe, and two of the sliding rods are vertically slidably mounted on the discharge pipe; A push plate, the push plate is arranged in the discharge pipe, and the push plate is fixedly connected to the sliding rod; A first spring, one end of which is fixedly mounted on the inner wall of the discharge pipe, and the other end of which is fixedly connected to the push plate; A cam is rotatably mounted on the discharge pipe, and the cam abuts against an end of the sliding rod away from the push plate.

When the amount of bulk grain accumulated in the discharge pipe decreases, the vertical downward pressure exerted by the bulk grain on the sliding rod decreases, and under the action of the third spring, the sliding rod and the push plate move vertically upward, and the upward movement of the sliding rod and the push plate drives the movable end of the third telescopic rod to extend, thereby improving the mechanical linkage of a bulk grain transfer metering device with automatic material level control.

[0031] The following is combined with Figure 1-7 This application is described in further detail.

[0032] The embodiment of the present application discloses a bulk grain transfer metering device with automatic material level control.

[0033] Reference Figure 1 and Figure 2 The bulk grain transfer metering device with automatic material level control includes a feed pipe 1, a buffer chute 2, a discharge pipe 3, a gate assembly 4 and a controller. A chute scale 11 is installed on the feed pipe 1. One end of the buffer chute 2 is connected to the feed pipe 1, and a capacitive distance sensor 23 is installed in the buffer chute 2. A high material point 21 and a low material point 22 are arranged in the buffer chute 2, the high material point 21 is arranged at the end of the buffer chute 2 away from the discharge pipe 3, and the low material point 22 is arranged at the end of the buffer chute 2 close to the discharge pipe 3. The discharge pipe 3 is connected to the end of the buffer chute 2 away from the discharge pipe 3. The gate assembly 4 is installed on the discharge pipe 3. The controller is connected to the gate assembly 4, the controller is used to control the gate assembly 4, and the controller is electrically connected to the capacitive distance sensor 23.

[0034] The bulk grain enters the buffer chute 2 through the feed pipe 1, and is weighed by the chute scale 11. At the same time, the bulk grain level in the buffer chute 2 is detected by the capacitive distance sensor 23, and the capacitive distance sensor 23 transmits the bulk grain level signal to the controller, and the controller controls the opening size of the gate assembly 4. When the material level is close to the high material point 21, the opening of the gate assembly 4 is increased, and when the material level is close to the low material point 22, the opening of the gate assembly 4 is reduced to ensure that the bulk grain level is always maintained between the high material point 21 and the low material point 22, thereby improving the discharge stability of the bulk grain transfer device.

[0035] Reference Figure 2 , Figure 3 and Figure 4 The gate assembly 4 includes two first telescopic rods 41 and a sliding plate 42. The fixed ends of the two first telescopic rods 41 are symmetrically and fixedly mounted on the discharge pipe 3, and the controller is electrically connected to the first telescopic rods 41. The sliding plate 42 is slidably mounted on the discharge pipe 3, and the sliding plate 42 is fixedly connected to the movable ends of the first telescopic rods 41.

[0036] When the material level is close to the high material point 21, the gate assembly 4 opening is increased, the controller controls the movable end of the first telescopic rod 41 to contract, and the movable end of the first telescopic rod 41 drives the two sliding plates 42 to move away from each other, increasing the diameter of the discharge pipe 3. When the material level is close to the low material point 22, the gate assembly 4 opening is reduced, the controller controls the movable end of the first telescopic rod 41 to extend, and the movable end of the first telescopic rod 41 drives the two sliding plates 42 to move toward each other, reducing the diameter of the discharge pipe 3, ensuring that the bulk grain material level is always maintained between the high material point 21 and the low material point 22, and improving the discharge stability of the bulk grain transfer device. Prevent materials from accumulating in the buffer chute 2, and avoid materials accumulating on the chute scale 11, which affects the metering accuracy of the chute scale 11.

[0037] Reference Figure 2 , Figure 3 and Figure 4 Two groups of shaking material components 6 are also installed in the discharge pipe 3. The two groups of shaking material components 6 are respectively connected to the two sliding plates 42. The two groups of shaking material components 6 include two sliding rods 61, a push plate 62, a first spring 63, a cam 64, a driven bevel gear 68, an active bevel gear 67, a spur gear 66, a rack 65, a third telescopic rod 69 and a second spring 691. The two sliding rods 61 are penetrated on the discharge pipe 3, the two sliding rods 61 are horizontally slidably installed on the discharge pipe 3, and the two sliding rods 61 are vertically slidably installed on the discharge pipe 3. The push plate 62 is arranged in the discharge pipe 3, and the push plate 62 is fixedly connected to the sliding rod 61. One end of the first spring 63 is fixedly installed on the inner wall of the discharge pipe 3, and the other end of the first spring 63 is fixedly connected to the push plate 62. The cam 64 is rotatably installed on the discharge pipe 3, and the cam 64 abuts against the end of the sliding rod 61 away from the push plate 62.

[0038] The driven bevel gear 68 is coaxial with and fixedly connected to the cam 64. The driving bevel gear 67 is meshed with the driven bevel gear 68. The spur gear 66 is coaxial with and fixedly connected to the driving bevel gear 67, and the spur gear 66 is rotatably mounted on the discharge pipe 3. The rack 65 is meshed with the spur gear 66, and the rack 65 is fixedly connected to the sliding plate 42.

[0040] When the sliding plate 42 slides, it drives the rack 65 to move, and the movement of the rack 65 drives the spur gear 66 to rotate, and the rotation of the spur gear 66 drives the active bevel gear 67 to rotate, and the active bevel gear 67 drives the driven bevel gear 68 to rotate, and the driven bevel gear 68 drives the cam 64 to rotate, and the rotation of the cam 64 drives the sliding rod 61 to move. The movement of the sliding rod 61 drives the push plate 62 to move synchronously. At the same time, under the action of the first spring 63, the sliding rod 61 is always in contact with the cam 64, so that the sliding rod 61 reciprocates, and then drives the push plate 62 to reciprocate. Through the reciprocating motion of the two push plates 62, the loose grain in the discharge pipe 3 is shaken to prevent the loose grain from accumulating in the discharge pipe 3 and failing to discharge normally.

[0041] When the amount of bulk grain accumulated in the discharge pipe 3 increases, the vertical downward pressure exerted by the bulk grain on the sliding rod 61 increases, causing the sliding rod 61 and the push plate 62 to move vertically downward. The sliding rod 61 and the push plate 62 move downward, thereby shortening the movable end of the third telescopic rod 69. When the amount of bulk grain accumulated in the discharge pipe 3 decreases, the vertical downward pressure exerted by the bulk grain on the sliding rod 61 decreases. Under the action of the third spring, the sliding rod 61 and the push plate 62 move vertically upward. The sliding rod 61 and the push plate 62 move upward, thereby extending the movable end of the third telescopic rod 69.
