Description

Technical Field

[0001] This application relates to the field of garden harvesting equipment, and in particular to a garden harvesting equipment with intelligent data transmission. Background Technology

[0002] With the development of data processing technology, it has played a significant role in improving the harvesting efficiency of agricultural planting. During the agricultural harvesting process, the integrated transmission and processing of various sensors and GPS data can help plan the harvesting path of modern harvesting equipment and adjust the harvesting status according to the lodging of crops to ensure comprehensive harvesting, reduce the possibility of harvesting omissions and secondary harvesting, greatly reduce the amount of harvesting labor, and help realize the intensive development of modern agriculture.

[0003] Existing harvesting equipment cuts the crop and then sends it to the intermediate conveying device via a screw conveyor. The conveying device continues to transport the crop from the header to the separation device. During the rolling process, the screening cylinder brushes away the straw piled on the surface of the screening plate and transfers it away from the inside of the harvesting equipment. However, in actual operation, the screening cylinder has limited effect on brushing away the straw stuck in the screening plate. As a result, the screening plate is easily blocked by the straw stuck inside, which affects the effective separation and screening of grains and straw.

[0004] To address this, we propose an intelligent data transmission field harvesting device. Based on the rolling and cleaning of straw, a flexible adhesive structure is added to ensure the separation of straw while also allowing for easy detachment, thus enabling continuous grain separation. Summary of the Invention

[0005] The purpose of this application is to improve garden harvesting equipment, providing an intelligent data transmission garden harvesting device compared to existing technologies. The device includes a harvester body, inside which is installed an arc-shaped screening plate and a screening roller above the screening plate. A brush plate with its tail end in contact with the surface of the screening roller is mounted around the surface of the screening roller. One side surface of the brush plate has a conical hole, and an adhesive cone block is slidably mounted through the conical hole. An electromagnetic plate is mounted on the inner wall of the brush plate. A compression spring with its tail end connected to the electromagnetic plate is connected to the end of the adhesive cone block near the electromagnetic plate. A supporting cylindrical tube is mounted on the surface of the electromagnetic plate, located outside the compression spring, and the compression spring is slidably connected to the inner wall of the supporting cylindrical tube. An inclined guide plate is mounted on the top of the harvester body. One end of the guide plate is connected to the end of the screening plate, and the other end of the guide plate extends out of the edge of the harvester body. When the screening drum is working normally, the rolling brush plate that is in contact with the screening plate can roll and clean the straw accumulated on the surface of the screening plate to the surface of the guide plate. When straw is stuck inside the screening plate, the exposed adhesive cone will poke the straw and follow the rotation of the screening drum to pull it off. When it moves to the three-quarters tangent point of the screening drum, the adhesive cone will retract due to the attraction between the electromagnetic plate and the adhesive cone. Combined with the gas diffused outward from the inside of the brush plate, the straw at the end of the adhesive cone can be smoothly detached and fall to the surface of the guide plate, so as to realize the periodic cleaning operation of stuck straw and ensure that the screening plate is in a clear state for normal ear and stalk separation.

[0006] Furthermore, the screening plate has screening cone holes inside, and the diameter of the screening cone holes increases from the inside to the outside, which facilitates the separation of the straw with grains stuck in the screening cone holes during the pulling and separating process of the connecting rod.

[0007] Furthermore, an air pump is installed on the surface of the harvester body. The output end of the air pump is connected to an air hose, and the tail end of the air hose extends into the interior of the screening drum through a rotating joint. The tail end of the brush plate is connected to the screening drum in a sealed manner. The air inflation process can be used to separate the straw from the end of the adhesive cone when the electromagnetic plate is started. It can also clean the straw juice on the surface of the adhesive cone.

[0008] Furthermore, the adhesive cone includes a magnetic block connected to the compression spring, and the electromagnetic plate has a magnetic attraction with the magnetic block when it is energized. A flexible sealing block is connected to the end of the magnetic block away from the compression spring, and a steel tip is connected to the end of the flexible sealing block away from the compression spring. The use of the flexible sealing block can enhance the sealing effect of the adhesive cone on the conical hole, prevent the brush plate from blowing air outward when the electromagnetic plate is not activated, and thus prevent the brush plate from having a reverse unblocking effect on the screening plate with straw stuck in it when it moves inside the screening plate, ensuring the ear and stalk separation effect of the harvester body.

[0009] Furthermore, the sum of the initial length of the compression spring and the lengths of the magnetic block and the flexible sealing block is greater than the distance between the electromagnetic plate and the conical hole, and the initial length of the compression spring is greater than the supporting round tube, ensuring that the adhesive cone block can be stably sealed and connected to the conical hole when the electromagnetic plate is not activated.

[0010] Furthermore, the height of the end of the screening plate near the guide plate is the same as the height at the three-quarters tangent point of the screening drum.

[0011] A smart data transmission field harvesting device, the operation of which includes the following steps:

[0012] S1. The harvester body starts and conveys the cut straw and grain mixture to the inside of the screening plate for preliminary screening and separation.

[0013] S2. The screening drum rotates counterclockwise, and the adhesive cones on the surface are exposed on the surface of the screen plate. During the rotation, the exposed adhesive cones will be stuck in the straw in the screen plate, and the stuck straw will be pulled away from the screen plate under the action of rotation.

[0014] S3. When the screening drum moves to the end of the screening plate near the guide plate, the electromagnetic plate is energized, the bonding cone is forced to retract inward, and the cone hole creates a gap. The wind inside the brush plate blows through the gap to the straw stuck at the end of the bonding cone. The straw detaches and falls to the surface of the guide plate, and slides down the surface of the guide plate to the harvesting ground.

[0015] Furthermore, the diameter of the tapered hole is no greater than the diameter of the end of the flexible sealing block near the magnetic block.

[0016] Optionally, the surface of the flexible sealing block is coated with a heat-insulating coating, and the interior of the flexible sealing block is provided with an isolation cavity. A quick-drying adhesive layer is installed inside the isolation cavity, and an inner rubber component is installed on the inner side of the quick-drying adhesive layer. After the flexible sealing block is damaged, the quick-drying adhesive layer is released to bond the inner rubber component to the conical hole, thereby ensuring the sealing effect and avoiding reverse drainage caused by gas release.

[0017] Optionally, the interior of the quick-drying adhesive layer is filled with oil-soluble quick-drying adhesive containing fluorescent particles, and the surface of the flexible sealing block near the quick-drying adhesive layer is coated with a light-shielding material.

[0018] Compared to existing technologies, the advantages of this application are:

[0019] (1) When the screening drum is working normally, the rolling brush plate that is in contact with the screening plate can roll and clean the straw accumulated on the surface of the screening plate to the surface of the guide plate. When straw is stuck inside the screening plate, the exposed adhesive cone will poke the straw and follow the rotation of the screening drum to achieve traction and separation. When it moves to the three-quarters tangent point of the screening drum, the adhesive cone will shrink inward due to the attraction between the electromagnetic plate and the adhesive cone. Combined with the gas diffused outward from the inside of the brush plate, the straw at the end of the adhesive cone can be smoothly separated and fall to the surface of the guide plate, so as to realize the periodic cleaning operation of the stuck straw and ensure that the screening plate is in a clear state for normal ear and straw separation.

[0020] (2) The use of flexible sealing blocks can enhance the sealing effect of adhesive cone blocks on cone holes, prevent the brush plate from blowing air outward when the electromagnetic plate is not activated, and thus prevent the brush plate from having a reverse unblocking effect on the screening plate with straw stuck in it when it moves inside the screening plate, ensuring the separation effect of ears and stalks of the harvester body.

[0021] (3) The length data of the compression spring, the steel tip and the flexible sealing block are used to ensure that the adhesive cone can be stably sealed and connected to the cone hole when the electromagnetic plate is not started.

[0022] (4) After the flexible sealing block is destroyed, the quick-drying adhesive layer is released to bond the inner rubber parts to the conical hole, thereby ensuring the sealing effect and avoiding reverse drainage caused by gas release.

[0023] (5) It facilitates the separation of straw with grains stuck in the screening cone during the pulling and separating process of the connecting rod. Attached Figure Description

Detailed Implementation

[0036] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0037] Example 1: This invention provides an intelligent data transmission field harvesting device. Please refer to [link / reference]. Figure 1-6 The harvester includes a harvester body 1. Inside the harvester body 1, there is an arc-shaped screening plate 2 and a screening roller 3 located above the screening plate 2. The surface of the screening roller 3 is surrounded by a brush plate 31 whose tail end is in contact with the surface of the screening plate 2. One side surface of the brush plate 31 is provided with a conical hole, and an adhesive cone block 32 is slidably installed through the conical hole. An electromagnetic plate 35 is installed on the inner wall of the brush plate 31. The end surface of the adhesive cone block 32 near the electromagnetic plate 35 is connected to a compression spring 33 whose tail end is connected to the surface of the electromagnetic plate 35. A support tube 34 located outside the compression spring 33 is installed on the surface of the electromagnetic plate 35, and the compression spring 33 is slidably connected to the inner wall of the support tube 34. An inclined guide plate 4 is installed on the top of the harvester body 1. One end of the guide plate 4 is connected to the end of the screening plate 2, and the other end of the guide plate 4 extends out of the edge of the harvester body 1.

[0038] Specifically, when the harvester body 1 is harvesting and separating grains from straw, the belt drive and the rotation of the harvester body 1 drive the screening drum 3 to rotate, which in turn drives the brush plate 31 to adhere to and clean the straw accumulated on the surface of the screening plate 2, achieving a rolling cleaning effect. During this process, for straw stuck in the mesh of the screening plate 2, the adhesive cones 32 exposed on the surface of the brush plate 31 can poke the stuck straw and pull it to clean it as the screening drum 3 rotates. When the screening drum 3 moves to the end of the screening plate 2, the electromagnetic plate 35 is activated to attract the adhesive cones 32, forcing the adhesive cones 32 to retract into the brush plate 31. At this time, the adhesive cones 32 with straw stuck on their surface can achieve a surface cleaning effect, so that the straw that falls to the surface of the guide plate 4 can slide smoothly to the ground where the harvester body 1 passes, ensuring the smooth flow of the screening plate 2 during the harvesting process.

[0039] The support tube 34 is used to support the compression spring 33, preventing the compression spring 33 from bending and deforming under the action of gravity, thereby ensuring that the adhesive cone 32 and the compression spring 33 always maintain a straight connection, and thus ensuring the smooth entry and exit of the adhesive cone 32 inside the cone hole.

[0040] Please see Figure 7 The screening plate 2 has a screening cone hole 21 inside, and the diameter of the screening cone hole 21 increases from the inside to the outside.

[0041] Specifically, if grains located in the mesh of the screening plate 2 remain on the surface of the straw stuck inside the screening plate 2, during the process of pulling and cleaning the straw, the grains are affected by the reduction in the aperture when they are pulled out of the screening cone hole 21, and are able to smoothly detach from the surface of the straw and fall into the space below the screening plate 2.

[0042] Please see Figure 2 An air pump 5 is installed on the surface of the harvester body 1. The output end of the air pump 5 is connected to an air hose, and the tail end of the air hose extends into the interior of the screening drum 3 through a rotating joint. The tail end of the brush plate 31 is connected to the screening drum 3 through a sealed connection.

[0043] Specifically, the air pump 5 is used to provide an air source. When the electromagnetic plate 35 is activated and drives the adhesive cone 32 to retract, the internal gas can be released through the gap between the cone-shaped hole and the adhesive cone 32, which enhances the effect of blowing away and cleaning the straw pierced by the tip of the adhesive cone 32. At the same time, it can also clean the juice left on the surface of the adhesive cone 32.

[0044] Please see Figure 8The adhesive cone block 32 includes a magnetic block 323 connected to the compression spring 33, and the electromagnetic plate 35 has a magnetic attraction with the magnetic block 323 when it is energized. A flexible sealing block 322 is connected to the end of the magnetic block 323 away from the compression spring 33, and a steel tip block 321 is connected to the end of the flexible sealing block 322 away from the compression spring 33.

[0045] Specifically, the magnetic block 323 is used to make the adhesive cone block 32 have a magnetic attraction effect, so as to better cooperate with the electromagnetic plate 35.

[0046] The 321 stainless steel spike is used to poke the straw, making it easier to pull and clean it up later.

[0047] The flexible sealing block 322 is made of rubber material and has a good sealing effect when it is engaged with the conical hole. This prevents the leakage of internal wind force of the brush plate 31 when the electromagnetic plate 35 is not activated. This also prevents the internal wind force of the brush plate 31 from blowing into the mesh of the screening plate 2 during the process of the brush plate 31 passing through the screening plate 2, causing the straw that was originally engaged in the mesh of the screening plate 2 to be blown into the grain storage space by the wind force, thus reducing the possibility of reverse unblocking.

[0048] The sum of the initial length of the compression spring 33 and the lengths of the magnetic block 323 and the flexible sealing block 322 is greater than the distance between the electromagnetic plate 35 and the conical hole, and the initial length of the compression spring 33 is greater than the supporting round tube 34.

[0049] Specifically, when the electromagnetic plate 35 is not activated, the connection state of the compression spring 33, the magnetic block 323, and the flexible sealing block 322 allows the flexible sealing block 322 to be in the conical hole. Under the inflated state inside the brush plate 31, the sealing and locking effect between the auxiliary flexible sealing block 322 and the conical hole can be enhanced.

[0050] The height of the end of the screening plate 2 near the guide plate 4 is the same as the height of the three-quarters tangent point of the screening roller 3.

[0051] Specifically, when the screening roller 3 moves to the three-quarters tangent point, the electromagnetic plate 35 is activated. At this time, the straw that is stuck on the surface of the adhesive cone block 32 is detached and falls onto the surface of the guide plate 4 that is transitionally connected to the screening plate 2, thereby realizing the straw conveying.

[0052] A smart data transmission field harvesting device, the operation of which includes the following steps:

[0053] S1. The harvester body 1 starts and conveys the cut straw and grain mixture to the inside of the screening plate 2 for preliminary screening and separation.

[0054] S2. The screening drum 3 rotates counterclockwise, and the adhesive cones 32 on the surface are exposed on the surface of the brush plate 31. During the rotation, the exposed adhesive cones 32 will poke the straw stuck in the screening plate 2, and under the pulling action of rotation, the stuck straw will be pulled away from the screening plate 2.

[0055] S3. When the screening roller 3 moves to the end of the screening plate 2 near the guide plate 4, the electromagnetic plate 35 is energized, the adhesive cone 32 is forced to retract inward, and the cone hole creates a gap. The wind inside the brush plate 31 blows through the gap to the straw stuck at the end of the adhesive cone 32. The straw detaches and falls to the surface of the guide plate 4, and slides down the surface of the guide plate 4 to the harvesting ground.

[0056] The diameter of the tapered hole is no greater than the diameter of the end of the flexible sealing block 322 near the magnetic block 323.

[0057] Specifically, the diameter difference between the conical hole and the magnetic block 323 prevents the magnetic block 323 from rubbing against the inner wall of the conical hole during the process of the adhesive cone block 32 retracting and extending to expose itself, thereby preventing the frictional heat from interfering with the demagnetization of the magnetic block 323.

[0058] Example 2: Please refer to Figure 9-10 Components identical or corresponding to those in Embodiment 1 are referred to by the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is that the surface of the flexible sealing block 322 is coated with a heat-insulating coating, the interior of the flexible sealing block 322 is provided with an isolation cavity, and a quick-drying adhesive layer 7 is installed inside the isolation cavity. An inner rubber component 6 is installed on the inner side of the quick-drying adhesive layer 7.

[0059] Specifically, when there are residual branches on the surface of the straw pierced by the steel tip 321, the flexible sealing block 322 may be damaged during the pulling process. At this time, the quick-drying adhesive in the quick-drying adhesive layer 7 is released and dries instantly, so that the bonding cone 32 can be bonded and fixed to the cone hole, forming a stable sealing effect and preventing the internal airflow from overflowing.

[0060] The interior of the quick-drying adhesive layer 7 is filled with oil-soluble quick-drying adhesive, and the quick-drying adhesive contains fluorescent particles. The surface of the flexible sealing block 322 near the quick-drying adhesive layer 7 is coated with a light-shielding material.

[0061] Specifically, when the quick-drying adhesive layer 7 is exposed and in action, the fluorescent particles inside are also released. By observing the location of the fluorescence, the location of the damaged flexible sealing block 322 in the cone block 32 bonded to the surface of the brush plate 31 can be determined, so that the quick-drying adhesive can be dissolved with insulating oil to repair and replace the damaged flexible sealing block 322.

[0062] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and its improved concept, should be covered within the scope of protection of this application.
