Description

Technical Field

[0001] This utility model relates to poultry farming equipment, and more specifically, to a feed supply device. Background Technology

[0002] With the continuous development of technology, feed supply in large-scale chicken farms has evolved from traditional manual feeding to a highly automated stage. For large-scale, plant-style chicken farms, feed is mostly supplied through feed supply devices. These devices typically consist of feed storage bins, pre-storage hoppers, and a feeding system. The main function of these devices is to automate feed delivery, reducing the need for manual operation. Specifically, feed storage bins are installed outside the plant, and feed is transported through pipelines to the pre-storage hoppers inside the plant, from where it is then distributed to each breeding line.

[0003] Currently, the most common method for conveying feed from storage bins to pre-storage hoppers is electric conveyor transport. Electric conveyors include belt conveyors, chain conveyors, and bucket elevators, which are driven by electric motors and can continuously and stably transport feed from the storage area to the plant. However, this method exposes the feed to the elements, making it more susceptible to weather conditions and requiring additional waterproofing. In addition, there is pneumatic conveying. This method uses compressed air as power to transport feed in fluid form through pipelines. It is not affected by external weather conditions and is therefore more widely used. However, pneumatic conveying also has certain drawbacks.

[0004] Currently, compressed air in pneumatic conveying systems is typically drawn directly from the outside using an air pump, and this compressed air is then used to power the feed flow within the pipeline. After the feed is delivered into the pre-storage hopper inside the plant, the gas needs to be filtered before being discharged. Furthermore, after the compressed air and feed enter the pre-storage hopper, the gas needs to be discharged promptly; otherwise, excessive air pressure in the hopper will force the air compressor to consume more power to overcome this pressure and achieve normal feeding. Therefore, pneumatic conveying systems consume a relatively large amount of energy, primarily due to the work required to compress air and overcome uncertain pressure differences. Based on this, this invention provides a feed supply device to solve the above problems. Utility Model Content

An air supply pipe is provided on the side of the feed storage cylinder away from the feeding pipe. A sealing box is connected to the end of the air supply pipe. An air extractor is installed in the sealing box. The output end of the air extractor is connected to the air supply pipe. A return pipe is connected to the end of the sealing box away from the air supply pipe. The return pipe is connected to the pre-storage hopper and extends into the pre-storage hopper. A filter is installed at the end of the return pipe that extends into the pre-storage hopper.

[0015] Beneficial effects

[0016] The advantages of this utility model are:

[0017] 1. This utility model is based on existing feed supply devices. By adding a sealed box and a return pipe between the feed storage cylinder and the pre-storage hopper, the feed supply device utilizes internal air to form a circulating airflow system. Compared with existing technologies, it avoids the problem of the vacuum pump having to do extra work to overcome abnormal pressure differences due to the gas not being discharged in time, thereby reducing the power consumption of the vacuum pump.

Detailed Implementation

[0022] The present invention will be further described below with reference to embodiments, but this does not constitute any limitation on the present invention. Any limited modifications made by any person within the scope of the claims of the present invention are still within the scope of the claims of the present invention.

[0023] See Figs. 1-2 This utility model discloses a feed supply device, comprising a feed storage cylinder 1 and a pre-storage hopper 5, with a feeding pipe 2 between the feed storage cylinder 1 and the pre-storage hopper 5, and an air supply pipe 7 on the side of the feed storage cylinder 1 away from the feeding pipe 2. In this embodiment, the original installation structure of the feed storage cylinder 1 and the pre-storage hopper 5 is not modified, so the specific installation structure can be retained as before, which can effectively save the cost of modifying the feed supply device.

[0024] In traditional feed supply devices, the air extractor is directly externally mounted for air extraction. However, in this embodiment, it is placed inside a sealed box 8. Specifically, the end of the air delivery pipe 7 is connected to the sealed box 8, and the air extractor 11 is installed inside the sealed box 8. Furthermore, the air extractor 11 used in this embodiment consists of a motor and an extractor head. The motor is located outside the sealed box 8, with its output shaft passing through the sealed box 8 and dynamically sealed to it. The extractor head is installed inside the sealed box 8, and its drive unit is dynamically connected to the motor's output shaft. This design facilitates motor maintenance and avoids the problem of the motor's lifespan being affected by the dusty environment inside the sealed box 8. The output end of the air extractor 11 is connected to the air delivery pipe 7, and the end of the sealed box 8 furthest from the air delivery pipe 7 is connected to a return pipe 9, which is connected to the pre-storage hopper 5. When the air extractor 11 is working, it draws air from the pre-storage hopper 5 through the return pipe 9, reducing the air pressure in the pre-storage hopper 5. The air drawn by the air extractor 11 is then sent through the air delivery pipe 7 to the discharge section below the feed storage cylinder 1, and feeds the feed there into the feeding pipe 2, thus conveying the feed in fluid form. Because the air pressure in the pre-storage hopper 5 is low, the fluid feed can be better delivered into the pre-storage hopper 5 under the action of high-pressure air. After the air and feed separate in the pre-storage hopper 5, the air is drawn back to the return pipe 9, thus forming a circulation system. That is, the feed supply device of this embodiment uses internal air to form a circulating airflow system, creating a pressure difference between the feeding pipe 2 and the pre-storage hopper 5. This pressure difference enables smoother delivery of fluid feed. Compared with the prior art, it avoids the problem of the air extractor having to do extra work to overcome the abnormal pressure difference due to the gas not being discharged in time, thereby reducing the power consumption of the air extractor and achieving the purpose of saving energy.

[0025] Additionally, the return pipe 9 extends into the pre-storage hopper 5, and a filter 14 is installed at one end of the return pipe 9 extending into the pre-storage hopper 5. The filter 14 at the end of the return pipe 9 prevents feed particles from flowing back into the return pipe 9. Therefore, the pre-storage hopper 5 can be configured as a sealed unit, requiring only a discharge port 6 at its bottom and a control valve 2 installed in the discharge port 6. When feed is being delivered to the pre-storage hopper 5, the control valve 2 is closed, creating a relatively sealed space within the entire feed supply device. When feeding is complete and the pre-storage hopper 5 needs to be emptied, simply open the control valve 2.

[0026] Considering the large amount of dust in the feed, if the filter is only filtered through the filter 14, the filter 14 will easily become clogged. Therefore, the filter is only used to filter feed particles, while the dust generated during the feeding process can be filtered out by setting a filter assembly in the sealed box 8.

[0027] Specifically, the filter assembly includes a collection hopper 13 and multiple filter screens 12. The collection hopper 13 is placed at the bottom of the sealed box 8 to collect the filtered dust. The inner wall of the sealed box 8 above the collection hopper 13 has slots that match the filter screens 12. The filter screens 12 are inserted into the slots, and all the filter screens 12 are located between the vacuum pump 11 and the return pipe 9. This design facilitates the removal, placement, cleaning, and replacement of the filter screens 12. Furthermore, the mesh size of the multiple filter screens 12 gradually increases from the return pipe 9 towards the vacuum pump 11 to achieve a better filtration effect.

[0028] Preferably, the multiple filter screens 12 are arranged at an angle in the sealed box 8, which facilitates the falling off of the filtered dust and reduces the rate at which dust accumulates on the filter screens 12.

[0029] In this embodiment, the sealing box 8 consists of a box body and a lid, which are hinged together and a sealing rubber strip is provided between them. The box body and lid are locked together by a locking device. This design ensures the sealing performance of the sealing box 8 and also facilitates the maintenance of its internal filter 12 and vacuum pump 11.

[0030] In this embodiment, an air supply pipe 10 is installed on the sealed box 8, and the air supply pipe 10 is connected to the interior of the sealed box 8. A control valve is installed in the air supply pipe 10. In actual application, it is difficult to achieve a complete seal between the sealed box 8 and the pre-storage hopper 5, and there will be some air leakage. Therefore, air needs to be supplied through the air supply pipe 10 to ensure that the circulating airflow system formed inside the feed supply device can effectively and reliably deliver feed. During implementation, the air supply amount can be set according to the amount of air leakage, which can be achieved by controlling the opening of the control valve. When supplying air, the air pressure inside the sealed box 8 is lower than that outside due to the gas flow, so the control valve can be opened directly, or air can be introduced into it through an air pump.

[0031] In this embodiment, the return pipe 9 is installed on the top of the pre-storage hopper 5, and the feeding pipe 2 is installed on the side wall of the pre-storage hopper 5. This design reduces the risk of feed being sucked into the return pipe 9.

[0032] A transparent pipe section 3 is provided at one end of the feeding pipe 2 near the feed storage cylinder 1. It is mainly used to observe whether the feeding is proceeding normally. If there is no feed in the transparent pipe section 3 during feeding, it means that there is no feed in the feed storage cylinder 1.

[0033] In this embodiment, an anti-clogging corner 4 is installed at the corner of the feeding pipe 2 to prevent feed from clogging at the corner of the feeding pipe 2. The anti-clogging corner 4 is already widely used in feed supply devices, and this invention does not improve upon it.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present utility model. These modifications and improvements will not affect the effectiveness of the present utility model or the practicality of the patent.
