Description

Technical Field

[0001] This utility model relates to the field of sunflower seed harvesting equipment, specifically to a sunflower seed anti-clogging feeding device. Background Technology

[0002] The sunflower harvester includes a harvesting platform, a threshing mechanism, a screening mechanism, a lifting mechanism, and a storage bin. The sunflower seeds screened by the screening mechanism need to be fed to the lifting mechanism, which then transports them to the storage bin. Currently, the screening mechanism's undersize outlet is a channel with a downward-sloping bottom. Due to the vibration of the screening mechanism, this channel needs to have a gap connection with the inlet of the lifting mechanism, extending into the inlet to allow for movement without interference. A soft cover is fixed to the outside of both the undersize outlet and the lifting mechanism's inlet to prevent leakage. The lifting mechanism uses a pneumatic conveying method; details can be found in [reference needed]. The patent application CN221634486U describes a sunflower seed pneumatic conveying and lifting device, which includes a blower, a feeding device, and a conveying pipe. During operation, sunflower seeds fall from the inlet of the feeding device. The airflow generated by the blower enters the feeding device. Part of the airflow enters the upper conveying channel and carries away the sunflower seeds that have fallen on the second partition. Part of the airflow enters the lower conveying channel. Since the inlet area of ​​the lower conveying channel is larger than the outlet area, the airflow velocity increases. The high-speed airflow lifts the material falling from the second partition to a storage box at a higher position through the conveying pipe.

[0003] However, in the above process, when the channel extends into the feed inlet, it is set horizontally and obliquely along the wind direction. This is to facilitate the material being blown away by the wind after it falls out, but it will cause the channel opening to narrow. As the sunflower seed harvest increases, it is easy for the seeds to accumulate in the channel opening, which slows down the material collection of the lifting mechanism and reduces the feeding efficiency. Secondly, a large number of sunflower seeds fall on the second partition and cannot slide off in time, causing accumulation and making it difficult for the lifting mechanism to feed the material. Utility Model Content

[0004] The purpose of this utility model is to provide a sunflower seed anti-clogging feeding device.

[0005] This utility model is implemented by the following technical solution:

[0006] A sunflower seed anti-clogging feeding device includes a fan, a ramp channel, a feeding device, and a conveying channel. The feeding device includes a rectangular shell and a rectangular cover. The bottom of the rectangular cover is connected to and fixed to the top of the rectangular shell. One side of the rectangular cover is provided with the feeding inlet of the feeding device. The feeding inlet of the feeding device extends into the undersize outlet channel of the screening mechanism. The other side of the rectangular cover and the top of the rectangular cover are provided with several through holes.

[0007] The two ends of the rectangular shell are respectively set as the air inlet and air outlet of the feeding device;

[0008] The air outlet of the blower is connected to the air inlet of the feeding device through the inclined channel, and the air outlet of the feeding device is connected to one end of the conveying channel through a bend.

[0009] One side of the inclined channel is connected to an air outlet pipe. The air outlet pipe is connected to one end of a hose through a valve. The other end of the hose passes through the housing of the screening mechanism and is connected to an air blower at the bottom of the undersize material outlet channel. The air blower is connected to the rectangular cover through the undersize material outlet channel.

[0010] Inside the rectangular housing, above the air inlet of the feeding device, a first partition is provided. The two sides of the first partition are fixed to the inner wall of the rectangular housing. One end of the first partition near the center of the interior of the rectangular housing is inclined downward. Inside the center of the rectangular housing, below the first partition, a second partition is provided. The two sides of the second partition are fixed to the inner wall of the rectangular housing. The second partition is inclined and parallel to the inclined downward end of the first partition. Inside the rectangular housing, above the air outlet of the feeding device, a baffle is provided. The two sides of the baffle are fixed to the inner wall of the rectangular housing.

[0011] Preferably, a window is provided on the other side of the rectangular cover, a door panel is hinged to the window, and several through holes are provided on the door panel on the other side of the rectangular cover. The door panel is movably fixed to the rectangular cover by a latch.

[0012] The advantages of this invention are as follows: The feeding device itself uses airflow blown by a blower to feed the material. When a large amount of material becomes blocked during the feeding process of the undersize material outlet channel, a portion of the blower's airflow can be directed towards the undersize material outlet channel to clear the blockage and improve feeding efficiency. Secondly, a large number of sunflower seeds fall into the rectangular shell, some landing on the second partition and some directly at the bottom of the rectangular shell. At this time, air blown out from the narrow opening acts on the top of the second partition, accelerating the conveying of sunflower seeds at the top of the second partition. Air also blown out from the narrow opening acts on the bottom of the rectangular shell, accelerating the conveying of sunflower seeds at the bottom of the rectangular shell, avoiding accumulation that affects efficiency, and enabling rapid air conveying to avoid feeding difficulties.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-6 As shown, a sunflower seed anti-clogging feeding device includes a fan 1, a ramp channel 2, a feeding device 3, and a conveying channel 4. The feeding device 3 includes a rectangular shell 3.1 and a rectangular cover 3.2. The bottom of the rectangular cover 3.2 is connected to and fixed to the top of the rectangular shell 3.1. The feeding device 3 has an inlet on one side of the rectangular cover 3.2. The undersize outlet channel 5 with a screening mechanism extends into the feeding device 3's inlet. Several through holes 6 are provided on the other side and the top of the rectangular cover 3.2.

[0023] The undersize material from the screening mechanism, namely sunflower seeds, slides through the undersize material outlet channel 5 into the rectangular cover 3.2 via the feed inlet of the feeding device 3, and then falls downward into the rectangular shell 3.1.

[0024] The two ends of the rectangular shell 3.1 are respectively set as the air inlet and air outlet of the feeding device 3;

[0025] The air outlet of the blower 1 is connected to the air inlet of the feeding device 3 through the inclined channel 2, and the air outlet of the feeding device 3 is connected to one end of the conveying channel 4 through the bend.

[0026] The blower 1 blows air through the inclined channel 2 to the feeding device 3, and uses the airflow to push the sunflower seeds through the vertical conveying channel 4 to the storage box. The outlet end of the conveying channel 4 passes through the bottom of the storage box and extends to a high position, so that the sunflower seeds are sprayed out and fall into the storage box for storage.

[0027] One side of the inclined channel 2 is connected to an air outlet pipe 7. The air outlet pipe 7 is connected to one end of a hose 9 through a valve 8. The other end of the hose 9 passes through the housing of the screening mechanism and is connected to an air blower 10 at the bottom of the undersize material outlet channel 5. The air blower 10 is connected to the rectangular cover 3.2 through the undersize material outlet channel 5.

[0028] When the air blown by blower 1 passes through the inclined channel 2, a portion is drawn out by the air outlet pipe 7, passes through the hose 9, and then blown out from the air outlet 10. The air outlet 10 is flat and elongated, and the airflow direction is diagonally downward along the bottom of the undersize material outlet channel 5, consistent with the discharge direction of the undersize material outlet channel 5. In this way, when a large amount of sunflower seeds clog or accumulate at the port of the undersize material outlet channel 5, the air blown out from the air outlet 10 can be used to clear the blockage. In particular, after the sunflower seed pile is cleared from the bottom, it can fall more quickly from the undersize material outlet channel 5 into the rectangular channel. The shape of the cover is 3.2; the valve 8 controls whether to blow air, and the opening degree of the valve 8 can control the blowing force; in actual use, a camera is fixed near the outlet end of the conveying channel 4, and there is a monitor in the harvester cab. If the storage of the storage box slows down or the discharge from the outlet end of the conveying channel 4 slows down, it can be judged that there may be a blockage in the undersize outlet channel 5. At this time, the valve 8 can be opened to blow air, or the opening degree of the valve 8 can be controlled to keep a small breeze blowing through the air outlet 10, which can also improve the passability of sunflower seeds.

[0029] When the air blower 10 blows air, it will blow some sunflower seeds or a very small amount of light impurities (not cleaned) to one side of the rectangular cover 3.2. At this time, the ventilation through several holes 6 can dissipate the air force, and the sunflower seeds or light impurities fall back into the rectangular shell 3.1.

[0030] Inside the rectangular shell 3.1, above the air inlet of the feeding device 3, there is a first partition 3.1.1. The two sides of the first partition 3.1.1 are fixed to the inner wall of the rectangular shell 3.1. The end of the first partition 3.1.1 near the center of the interior of the rectangular shell 3.1 is inclined downward. Inside the center of the interior of the rectangular shell 3.1, below the first partition 3.1.1, there is a second partition 3.1.2. The two sides of the second partition 3.1.2 are fixed to the inner wall of the rectangular shell 3.1. The second partition 3.1.2 is inclined and parallel to the inclined downward end of the first partition 3.1.1. The second partition 3.1.2 is also located below the outlet end of the half-screen material outlet channel 5. Inside the rectangular shell 3.1, above the air outlet of the feeding device 3, there is a baffle 3.1.3. The two sides of the baffle 3.1.3 are fixed to the inner wall of the rectangular shell 3.1.

[0031] When air passes through the rectangular shell 3.1, it is restricted by the first partition 3.1.1, blowing along the bottom of the first partition 3.1.1 into the interior of the rectangular shell 3.1, and does not directly dissipate upwards, thus reducing the airflow force. Then, the air passes between the first partition 3.1.1 and the second partition 3.1.2. Due to the downward-sloping end of the first partition 3.1.1, the air blows out along the top of the second partition 3.1.2. The narrow vent has an accelerating effect on the airflow, and this effect also acts above the second partition 3.1.2. Simultaneously, air also passes between the second partition 3.1.2 and the bottom of the rectangular shell 3.1. The smaller vent also has an accelerating effect on the airflow. Furthermore, the effect is applied above the bottom of the rectangular shell 3.1; when sunflower seeds enter the rectangular shell 3.1, some first fall on the top of the second partition 3.1.2, and then fall to the bottom of the rectangular shell 3.1 along the tilt angle, while others fall directly to the bottom of the rectangular shell 3.1. At this time, the airflow between the first partition 3.1.1 and the second partition 3.1.2 sends the sunflower seeds on the top of the second partition 3.1.2, and the airflow between the second partition 3.1.2 and the bottom of the rectangular shell 3.1 sends the sunflower seeds at the bottom of the rectangular shell 3.1, making the sunflower seeds faster to be transported, which can play a role in transporting a large number of sunflower seeds; the narrow opening has a fast gas flow rate, and the principle is similar to the Venturi effect.

[0032] A window 11 is provided on the other side of the rectangular cover 3.2. A door panel 12 is hinged to the window 11. Several through holes 6 are provided on the door panel 12 on the other side of the rectangular cover 3.2. The door panel 12 is movably fixed to the rectangular cover 3.2 by a latch. Opening the door panel 12 facilitates maintenance and repair of the rectangular shell 3.1, the rectangular cover 3.2, the screened material outlet channel 5 and other structures through the window 11.

[0033] Working principle: When this utility model is in use, the sunflower seeds that are screened out slide into the rectangular cover 3.2 through the feed inlet of the feeding device 3 via the screened material outlet channel 5, and then fall down into the rectangular shell 3.1. The fan 1 blows air into the feeding device 3 through the inclined channel 2, and uses the airflow to push the sunflower seeds through the vertical conveying channel 4 to the storage box.

[0034] A portion of the air blown out by the blower 1 is led out by the air outlet pipe 7 and blown out through the hose 9 from the air outlet 10. The blowing direction is consistent with the discharge direction of the undersize material outlet channel 5. When a large number of sunflower seeds are blocked or accumulated at the port of the undersize material outlet channel 5, the air blown out by the air outlet 10 can be used to clear the blockage.

[0035] When sunflower seeds enter the rectangular shell 3.1, some first fall onto the top of the second partition 3.1.2 and then drop to the bottom of the rectangular shell 3.1 along the inclined angle. Others fall directly to the bottom of the rectangular shell 3.1. At this time, the airflow between the first partition 3.1.1 and the second partition 3.1.2 sends the sunflower seeds at the top of the second partition 3.1.2, and the airflow between the second partition 3.1.2 and the bottom of the rectangular shell 3.1 sends the sunflower seeds at the bottom of the rectangular shell 3.1. This allows the sunflower seeds to be transported more quickly and effectively transports a large number of sunflower seeds.

[0036] Advantages: The feeding device 3 itself uses the airflow blown by the blower 1 to feed the material. When a large amount of material gets blocked during the feeding process of the undersize material outlet channel 5, a portion of the airflow from the blower 1 can be directed towards the undersize material outlet channel 5 to clear the blockage and improve feeding efficiency. Secondly, a large number of sunflower seeds fall into the rectangular shell 3.1, some of which fall onto the second partition 3.1.2, and some fall directly to the bottom of the rectangular shell 3.1. At this time, the air blown out from the narrow opening acts on the top of the second partition 3.1.2, accelerating the conveying of the sunflower seeds on the top of the second partition 3.1.2. The air also blown out from the narrow opening acts on the bottom of the rectangular shell 3.1, accelerating the conveying of the sunflower seeds at the bottom of the rectangular shell 3.1, avoiding accumulation that affects efficiency. It can be quickly pneumatically conveyed, avoiding feeding difficulties.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
