Description

Technical Field

[0001] This invention relates to the field of maize pollination technology, and in particular to an adjustable intelligent precision pollen collection and pollination integrated device for maize hybridization. Background Technology

[0002] Hybrid breeding of maize is a core method in modern maize breeding, playing a crucial role in developing new varieties that are high-yielding, of high quality, resistant to multiple diseases, and widely adaptable. The successful implementation of this technology heavily relies on two key steps: first, the efficient and highly active collection of pollen from the male parent; and second, the precise and timely transfer of pollen to the female ear of the female parent. However, in current breeding and seed production practices, pollen collection and ear pollination are usually treated as two separate processes, completed by single-function instruments or manually, resulting in a series of technical bottlenecks that urgently need to be addressed.

[0003] In pollen collection, traditional methods often involve directly cutting off the tassels or using collection bags or tubes. These methods have significant drawbacks: First, cutting off the tassels damages the plant and prevents the reuse of pollen; second, forcibly inserting the scattered tassels into the collection device can easily damage or break the anthers, leading to pollen loss and decreased activity, as well as low collection efficiency.

[0004] In terms of pollination, manual pollination is easily affected by the operator's skill level, resulting in uneven pollination and serious pollen waste; spraying pollen in windy conditions in the field results in huge pollen loss and is prone to pollen contamination between different varieties, which seriously affects the purity of hybridization; while bagging pollination can avoid pollen contamination, it is cumbersome to operate, extremely inefficient, and cannot achieve precise quantitative pollination.

[0005] Most existing pollination devices, whether sleeve-type or spray-type, are designed based on the assumption that the female ear has sufficient operating space so that the instrument opening can be smoothly inserted into or aligned with the ear. However, when there is almost no gap between the female ear and the stem, the feasibility of operation is extremely low. Attempting to forcibly insert a conventional rigid pollination shell or pollination nozzle into the narrow space between the female ear and the stem is not only extremely difficult to operate, but also very likely to cause severe mechanical damage such as compression and scratching to the delicate female ear bracts, silks, and even the stem itself during the insertion process. Such damage will directly lead to pollination failure or poor grain development, causing irreversible loss of valuable breeding materials. Summary of the Invention

[0006] This application provides an adjustable, intelligent, precise pollen collection and pollination integrated device for hybrid maize. It solves the problems of existing devices where, during pollen collection from tassels, the female ear is typically inserted into the collection tube, which is easily damaged during insertion due to the tassels' dispersed shape, leading to reduced pollen collection efficiency. Furthermore, individual spraying during pollination results in low success rates. Additionally, when the female ear is close to the maize stalk, it is impossible to individually cover it with the device. This application achieves a solution where, compared to traditional spraying, the device completely envelops the female ear, significantly reducing pollen waste and contamination of non-target plants. The V-shaped opening formed by the two collection slots improves pollen collection from the surface of the tassel, allowing the tassel to be completely moved into the pollination shell for pollen collection. To address the issue of the close proximity between the female ear and the main stalk of corn, this device places the female ear and the corn stalk together inside. Operators no longer need to precisely align the fragile female ear; they only need to align the opening of the device with the stalk and fasten it. This greatly reduces the difficulty of operation and the technical requirements, allowing even inexperienced workers to quickly get started and reducing the risk of damaging the female ear due to stressful operation. It also avoids pulling and squeezing the female ear in a confined space, minimizing mechanical damage to the corn female ear and promoting normal kernel development after pollination.

[0007] This application provides an adjustable intelligent precision pollen collection and pollination integrated device for maize hybrids, including a pollination component;

[0008] The pollination assembly includes a pollination shell and a sealing component; The sealing components include a base plate, an arc plate, an airbag, and a baffle. There are two pollination components, arranged symmetrically. The pollination shell is arc-shaped, and the two pollination shells are rotatably connected. The two pollination shells fit together to form a cylindrical shape that runs through its axis. The base plate is fixed inside the pollination shell, the arc-shaped plate is fixed on the base plate, the airbag is arc-shaped, and the airbag is fixed in the inner circle of the arc-shaped plate. There are two baffles, which are fixed to both ends of the curved plate respectively; When collecting pollen from the male tassel, the corn tassel enters from the top of the cylindrical shape formed by the two pollinating shells fitting together. During pollination of the female ear, the pollination shells in the two pollination components are kept far apart, and the corn stalk and female ear are placed between the two air bladders for clamping and sealing pollination.

[0009] As an improvement, the base plate is arc-shaped, with the outer ring of the base plate fixed to the inner wall of the pollination shell, and the outer ring of the arc-shaped plate fixed to the inner ring of the base plate. The baffle is fixed to the inner wall of the pollination shell and the side of the bottom plate; The axes of the two pollinating shells are parallel to each other, and when the two pollinating shells are in contact with each other, the axes of the two pollinating shells are on the same straight line. The pollination shell, bottom plate, arc plate, and baffle plate together form the storage cavity for storing pollen. When the pollination shells inside the two pollination components are in contact with each other, the bottom plate, arc plate, airbag and baffle inside the two pollination components are also in contact with each other, sealing the lower end of the two pollination shells. When the two base plates and the two curved plates are attached to each other, they all form a cylindrical shape that runs through their axes.

[0010] As an improvement, the pollination assembly also includes a collection tank, an exhaust vent, a net, a barrier membrane, and a reset plate; A collection trough is provided on one side of the pollination shell, and the collection trough is located at the top of the pollination shell; Vent holes are made on the side of the pollination shell, and an intercepting net is fixed inside the vent holes. The mesh diameter of the intercepting net is smaller than the diameter of the pollen. When the pollination shells inside the two pollination components are in contact with each other, the two collection grooves form a V-shape. An interception membrane made of rubber is fixed inside the collection tank; A reset plate is rotatably installed inside the collection tank, with the reset plate located at the top of the collection tank, and the intercepting membrane is fixed to one side of the reset plate; A torsion spring is fitted on the rotating shaft that rotatably connects the reset plate and the collection tank, with the two ends of the torsion spring fixed to the reset plate and the collection tank respectively. When the pollination shells inside the two pollination components are in contact with each other, the two barrier membranes are in contact with each other.

[0011] As an improvement, the pollination assembly also includes an operating component, which includes a telescopic rod, a fixing block, and a control button; The fixing block is fixed to one side of the pollination shell, and one end of the telescopic rod is fixed to the lower side of the fixing block. The telescopic rod is an electric telescopic rod. The control button is fixed to the outside of the fixed sleeve of the telescopic rod; The control button is electrically connected to the telescopic pole.

[0012] As an improvement, the pollination assembly also includes a cover; The cover assembly includes a mounting block, a cover plate, a motor, a groove, and an adhesive film; The mounting block is fixed to one side of the pollination shell, the cover plate is rotatably connected to the mounting block, the motor is fixed to the mounting block, and the output end of the motor is fixed to the rotating rod that is rotatably connected to the cover plate and the mounting block. When the mounting block is placed on the pollination shell and the pollination shells in the two pollination components are in contact with each other, the two mounting blocks in the two pollination components are in contact with each other, sealing the upper end of the pollination shell. In the initial state, when the mounting block cover is placed on the pollination shell, the side of the reset plate is in contact with the cover plate; A groove is made on one side of the cover plate, and an adhesive film is fixed in the groove. The adhesive film is made of rubber. When the mounting block cover is placed on the pollination shell and the pollination shells in the two pollination components are attached to each other, the two grooves on the two cover plates are connected to each other, and the two bonding films in the two grooves are attached to each other.

[0013] As an improvement, the pollination assembly also includes a pollination component; The pollination equipment includes an air pump and an air delivery block; The air pump is fixed on the outside of the pollination shell, the air conveying block is arc-shaped and fixed in the inner ring of the pollination shell. The air conveying block is located in the storage cavity for storing pollen, which is composed of the pollination shell, the bottom plate, the arc plate and the baffle. The gas delivery block has multiple one-way valves on its surface, and the gas delivery block is connected to the output end of the air pump.

[0014] As an improvement, the pollination component also includes magnets; Magnets are fixed to one side of the pollination shell; When the pollination shells inside the two pollination components are attached to each other, the two magnets adhere and attract each other.

[0015] As an improvement, a tapping component is also included; The tapping assembly includes a motor, a rotating rod, and a tapping stick; Motor 2 is located on the outside of the pollination shell, and the rotating rod is rotatably connected inside the pollination shell. The output end of motor 2 is fixed on the rotating shaft that is rotatably connected to the rotating rod and the pollination shell. The patting stick is fixed to the rotating rod and is made of rubber. When the second motor drives the rotating rod to rotate, the patting rod pats the corn stalks. The tapping component is located on one side of the collection tank.

[0016] As an improvement, the pollination component also includes an energy storage battery; The energy storage battery is detachably mounted on one side of the pollination shell; Motor 1, Motor 2, and the control buttons are all electrically connected to the energy storage battery; The control buttons are electrically connected to motor one and motor two.

[0017] As an improvement, a limit band is also included; The two ends of the limiting band are respectively fixed to the inner ring of one end of the arc plate inside the two pollination components; When the two pollination components are in the open state, the two ends of the limiting band are respectively fixed to the inner rings of the two arc-shaped plates inside the two pollination components at the ends that are far apart from each other; The limiting band is located at the center of the airbag, and both the upper and lower ends of the limiting band are two to four centimeters away from the top and bottom of the airbag, respectively. The length of the limiting band is consistent with the circumference of the inner circle of the vertically penetrating cylinder formed by the two arc plates; When the two pollination components hold the corn stalk and the female ear, the limiting band is in contact with the corn stalk and the female ear, and the air bladders on both sides of the limiting band are in contact with the corn stalk and the female ear.

[0018] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: Firstly, the collected pollen is stored directly inside the pollination shell of the device, avoiding loss of viability and quantity due to exposure to the external environment during transfer. The pollen is concentrated and directly applied to the target female ear; compared to traditional spraying, the device completely encloses the female ear, greatly reducing pollen waste and contamination of non-target plants. The airbag seal effectively isolates it from wind interference, ensuring that the pollen adheres stably to the filaments of the female ear, unaffected by adverse weather conditions. This is crucial for ensuring the purity and success rate of hybridization experiments. The V-shaped opening formed by the two collection troughs improves the collection effect of pollen from the surface of the male ear, allowing the male ear to be completely moved into the pollination shell for pollen collection.

[0019] To address the issue of the close proximity between the female ear and the main stalk of corn, this device places the female ear and the corn stalk together inside. Operators no longer need to precisely align the fragile female ear; they only need to align the opening of the device with the stalk and fasten it. This greatly reduces the difficulty of operation and the technical requirements, allowing even inexperienced workers to quickly get started and reducing the risk of damaging the female ear due to stressful operation. It also avoids pulling and squeezing the female ear in a confined space, minimizing mechanical damage to the corn female ear and promoting normal kernel development after pollination.

[0020] Secondly, operators simply need to place the corn stalks and ears along the limiting bands. The limiting bands clearly indicate the correct placement position, namely the central area between the two airbags. This ensures that when the device is closed, the flexible airbags accurately hold the corn stalks and ears, preventing them from colliding or being squeezed by hard baffles or other components. This provides crucial protection for the precious hybrid material and greatly improves the safety and reliability of the operation. Attached Figure Description

[0026] Example 1: As Figures 1-8 As shown, this application discloses an adjustable intelligent precision pollen collection and pollination integrated device for maize hybrids, including a pollination component 100 and a tapping component 200. The pollination assembly 100 includes a pollination shell 110, a collection tank 111, an exhaust hole 112, an interception net 113, an interception membrane 120, a reset plate 130, an operating component 140, a cover component 150, a pollination component 160, an energy storage battery 170, a sealing component 180, and a magnet 190. The sealing component 180 includes a base plate 181, an arc-shaped plate 182, an airbag 183, and a baffle 184; There are two pollination components 100, which are arranged symmetrically. The pollination shell 110 is arc-shaped, and the two pollination shells 110 are rotatably connected. The two pollination shells 110 fit together to form a cylindrical shape that runs through its axis. The axes of the two pollination shells 110 are parallel to each other, and when the two pollination shells 110 are in contact with each other, the axes of the two pollination shells 110 are on the same straight line.

[0027] The base plate 181 is fixed inside the pollination shell 110, the arc plate 182 is fixed on the base plate 181, the airbag 183 is arc-shaped, and the airbag 183 is fixed in the inner circle of the arc plate 182. The base plate 181 is arc-shaped, and the outer ring of the base plate 181 is fixed to the inner wall of the pollination shell 110. The outer ring of the arc-shaped plate 182 is fixed to the inner ring of the base plate 181. There are two baffles 184, which are fixed to both ends of the arc-shaped plate 182 respectively; Baffle 184 is fixed to the inner wall of pollination shell 110 and the upper side of bottom plate 181; The pollination shell 110, the base plate 181, the arc-shaped plate 182, and the baffle 184 together constitute the storage cavity for storing pollen. When collecting pollen from the male ear, the corn male ear enters from the top of the cylindrical shape formed by the two pollinating shells 110 fitting together. During pollination of the female ear, the pollination shells 110 in the two pollination components 100 are separated from each other, and the corn stalk and female ear are placed between the two air bags 183 for clamping and sealing pollination.

[0028] When the pollination shells 110 inside the two pollination components 100 are in contact with each other, the bottom plate 181, arc plate 182, airbag 183 and baffle 184 inside the two pollination components 100 are also in contact with each other, sealing the lower ends of the two pollination shells 110.

[0029] When the two base plates 181 and the two arc-shaped plates 182 are attached to each other, they all form a cylindrical shape that runs through their axis.

[0030] Specifically, when pollinating corn ears, when the ear is close to the corn stalk, the two pollination components 100 are placed far apart and open to each other. The corn stalk and ear are placed together between the two air bladders 183. Then, the two pollination components 100 are brought close together and fitted together. The corn stalk and ear are held in place by the two air bladders 183. The bottom plate 181, arc plate 182, air bladder 183 and baffle 184 inside the two pollination components 100 are also fitted together to seal the lower end of the two pollination shells 110, preventing a large amount of pollen from escaping from the device during the pollination process.

[0031] When the two pollination components 100 are used away from each other, the outer arc surface of the pollination component 100 faces itself, and the opening of the open part faces the corn stalk and female ear, making it convenient to put it into the device.

[0032] A collection groove 111 is provided on one side of the pollination shell 110, and the collection groove 111 is located at the uppermost end of the pollination shell 110. A vent hole 112 is provided on the side of the pollination shell 110, and an intercepting net 113 is fixed inside the vent hole 112. The mesh diameter of the intercepting net 113 is smaller than the diameter of the pollen. When the pollination shells 110 inside the two pollination components 100 are in contact with each other, the two collection grooves 111 form a V shape. An intercepting membrane 120 is fixed inside the collection tank 111. The intercepting membrane 120 is made of rubber. A reset plate 130 is rotatably installed inside the collection tank 111. The reset plate 130 is located at the uppermost end of the collection tank 111, and the intercepting membrane 120 is fixed to one side of the reset plate 130. A torsion spring is fitted on the rotating shaft that rotatably connects the reset plate 130 and the collection tank 111, and the two ends of the torsion spring are fixed on the reset plate 130 and the collection tank 111 respectively. When the pollination shells 110 inside the two pollination components 100 are attached to each other, the two barrier films 120 are attached to each other.

[0033] Specifically, when collecting pollen from maize tassels, the corn stalk is positioned between two reset plates 130. As the stalk moves downward or the device moves upward, the stalk continuously presses down on the reset plates 130, creating a gap between the two intercepting membranes 120. The corn stalk and tassel then enter the space between the two intercepting membranes 120 and between the two pollination shells 110 to collect pollen. After the reset plates 130 are no longer pressed by the stalk, they quickly reset via a torsion spring on the rotating shaft.

[0034] After pollen collection is complete, the corn stalks or moving device can be pulled outward to pull the stalks and tassels out between the two intercepting membranes 120.

[0035] The operating component 140 includes a telescopic rod 141, a fixing block 142, and a control button 143; The fixing block 142 is fixed to one side of the pollination shell 110, and one end of the telescopic rod 141 is fixed to the lower side of the fixing block 142. The telescopic rod 141 is an electric telescopic rod. The control button 143 is fixed to the outside of the fixed sleeve of the telescopic rod 141; The control button 143 is electrically connected to the telescopic rod 141.

[0036] Specifically, when encountering corn stalks with a high height, the height of the pollination shell 110 can be adjusted by adjusting the height of the telescopic rod 141, and the fixed sleeve of the telescopic rod 141 can be used as a handle to facilitate the handling of the entire device. Furthermore, by controlling the length of the telescopic rod 141 on one side to extend and touch the ground, it can assist in positioning, distribute the weight of the device, and improve the convenience of use.

[0037] The control button 143 allows for easy control of the extension and retraction of the telescopic rod 141.

[0038] The cover 150 includes a mounting block 151, a cover plate 152, a motor 153, a groove 154, and an adhesive film 155; Mounting block 151 is fixed on one side of pollination shell 110, cover plate 152 is rotatably connected to mounting block 151, motor 153 is fixed to mounting block 151, and the output end of motor 153 is fixed to the rotating rod rotatably connected to cover plate 152 and mounting block 151. When the mounting block 151 is placed on the pollination shell 110 and the pollination shells 110 in the two pollination components 100 are in contact with each other, the two mounting blocks 151 in the two pollination components 100 are in contact with each other, sealing the upper end of the pollination shell 110. In the initial state, when the mounting block 151 is placed on the pollination shell 110, the upper side of the reset plate 130 is in contact with the cover plate 152; A groove 154 is provided on one side of the cover plate 152, and an adhesive film 155 is fixed in the groove 154. The adhesive film 155 is made of rubber. When the mounting block 151 is placed on the pollination shell 110 and the pollination shells 110 in the two pollination components 100 are in contact with each other, the two grooves 154 on the two cover plates 152 are connected to each other, and the two bonding films 155 in the two grooves 154 are in contact with each other.

[0039] Specifically, the operation of motor 153 can be controlled by control button 143, thereby controlling the opening or closing of cover 152; When collecting pollen from the male spike, the cover plate 152 is first opened by the motor 153. After the male spike presses down on the reset plate 130 and enters the pollination shell 110, the motor 153 controls the cover plate 152 to cover the pollination shell 110 for sealing. When collecting pollen from the male spike again, the cover plate 152 is opened again, and this process is repeated. During the pollination operation, the cover plate 152 is always placed on the pollination shell 110. When the corn stalk and female ear are put into the device, the corn stalk is located in the groove 154 and is sealed by the bonding film 155.

[0040] Pollination component 160 includes an air pump 161 and an air delivery block 162; The air pump 161 is fixed on the outside of the pollination shell 110. The air conveying block 162 is arc-shaped and fixed on the inner ring of the pollination shell 110. The air conveying block 162 is located in the storage cavity for storing pollen, which is formed by the pollination shell 110, the bottom plate 181, the arc plate 182 and the baffle 184. The surface of the gas delivery block 162 is equipped with multiple one-way valves, and the gas delivery block 162 is connected to the output end of the air pump 161.

[0041] Specifically, during the pollination operation, the corn stalk and female ear are placed between two air bags 183. After being sealed and fitted by the air bags 183, the air pump 161 operates to supply air to the air conveying block 162. Multiple one-way valves on the surface of the air conveying block 162 blow out gas, continuously blowing up the pollen in the pollen storage cavity formed by the pollination shell 110, the bottom plate 181, the arc plate 182, and the baffle 184, and pollinating the female ear located in the device.

[0042] During the pollination process, the gas blown out by the air supply block 162 is discharged through the exhaust hole 112, and during the exhaust process, the pollen is intercepted by the interception net 113.

[0043] Magnet 190 is fixed to one side of pollination shell 110; When the pollination shells 110 inside the two pollination components 100 are attached to each other, the two magnets 190 are attached and attracted to each other.

[0044] Specifically, the two pollination shells 110 are brought into contact with each other by the mutual attraction between the two magnets 190, thus fixing the position between the two pollination shells 110. When it is necessary to open and separate the two pollination shells 110, the worker only needs to use both hands to separate the two pollination shells 110.

[0045] The tapping assembly 200 includes a motor 210, a rotating rod 220, and a tapping stick 230; Motor 210 is located on the outside of pollination shell 110, and rotating rod 220 is rotatably connected inside pollination shell 110. The output end of motor 210 is fixed on the rotating shaft that is rotatably connected to rotating rod 220 and pollination shell 110. The patting stick 230 is fixed on the rotating rod 220, and the patting stick 230 is made of rubber. When motor 210 drives rotating rod 220 to rotate, beater 230 beats corn stalks. The tapping component 200 is located on one side of the collection tank 111.

[0046] Specifically, during the pollen collection process, after the corn tassels enter the pollination shell 110 and the cover plate 152 is placed on the pollination shell 110, the motor 210 drives the rotating rod 220 to rotate, causing the beating rod 230 to beat the corn stalks, thereby causing the corn tassels to vibrate and shake off the pollen on the surface. The shaken pollen falls and is collected in the storage cavity formed by the pollination shell 110, the bottom plate 181, the arc plate 182, and the baffle 184, and the collection operation is carried out.

[0047] The energy storage battery 170 is detachably mounted on one side of the pollination shell 110; Motor 153, Motor 210 and control button 143 are all electrically connected to energy storage battery 170; The control buttons 143 are electrically connected to motor 153 and motor 210.

[0048] The start and stop of motor 153, motor 210 and telescopic rod 141 are controlled by control button 143.

[0049] The energy storage battery 170 and the control button 143 are existing technologies and will not be described in detail here.

[0050] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages: The collected pollen is stored directly inside the pollination shell 110 of the device, avoiding loss of viability and quantity due to exposure to the external environment during transfer. The pollen is concentrated and directly applied to the target female ear. Compared with traditional pollination, the device completely encloses the female ear, greatly reducing pollen waste and contamination of non-target plants. The airbag 183 effectively isolates wind interference, ensuring that the pollen can stably adhere to the filaments of the female ear, unaffected by adverse weather conditions. This is crucial for ensuring the purity and success rate of the hybridization experiment. The V-shaped opening formed by the two collection troughs 111 improves the collection effect of pollen on the surface of the male ear, allowing the male ear to be completely moved into the pollination shell 110 for pollen collection.

[0051] To address the issue of the close proximity between the female ear and the main stalk of corn, this device places the female ear and the corn stalk together inside. Operators no longer need to precisely align the fragile female ear; they only need to align the opening of the device with the stalk and fasten it. This greatly reduces the difficulty of operation and the technical requirements, allowing even inexperienced workers to quickly get started and reducing the risk of damaging the female ear due to stressful operation. It also avoids pulling and squeezing the female ear in a confined space, minimizing mechanical damage to the corn female ear and promoting normal kernel development after pollination.

[0052] Example 2: During the use of the above-mentioned device, the corn stalk and the female ear are placed together between the airbags 183 for clamping and sealing. However, during the clamping process between the corn stalk and the two pollination components 100, the corn stalk or the device itself may obstruct the worker's judgment of the placement position, easily resulting in the corn stalk or female ear being clamped and damaged. Therefore, the solution in Example 1 is improved as follows: Figure 8 As shown: It also includes a 300mm limit band; The two ends of the limiting band 300 are respectively fixed to the inner ring of one end of the arc plate 182 inside the two pollination components 100; When the two pollination components 100 are in the open state, the two ends of the limiting band 300 are respectively fixed to the inner rings of the two arc plates 182 inside the two pollination components 100 at the ends that are far apart from each other. The limiting band 300 is located at the center of the airbag 183, and the upper and lower ends of the limiting band 300 are two to four centimeters away from the uppermost and lowermost ends of the airbag 183. The length of the limiting band 300 is consistent with the inner circumference of the vertically penetrating cylindrical shape formed by the two arc plates 182; Specifically, the length of the limiting band 300 is consistent with the inner circumference of the vertically penetrating cylinder formed by the two arc-shaped plates 182. When clamping the corn stalk and female ear, it can keep them always between the two arc-shaped plates 182 and prevent them from being clamped by the deepest baffle 184 after the two pollination components 100 are opened.

[0053] When the two pollination components 100 clamp the corn stalk and the female ear, the limiting band 300 is in contact with the corn stalk and the female ear, and the air bladders 183 on both the upper and lower sides of the limiting band 300 are in contact with the corn stalk and the female ear.

[0054] Specifically, when the corn stalk and ear are placed together between the air bladders 183, the corn stalk and ear will abut against the limiting band 300. The limiting band 300 restricts the position of the corn stalk and ear, preventing them from being located between the two air bladders 183 when the corn stalk and ear are clamped, instead of between the two pollination components 100 after they are opened, and thus preventing damage to the clamping mechanism.

[0055] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages: Operators simply need to place the corn stalks and ears along the limiting band 300. The limiting band 300 clearly indicates the correct placement position, namely the central area between the two airbags 183. This ensures that when the device is closed, the flexible airbags 183 accurately hold the corn stalks and ears, preventing them from colliding or being squeezed by rigid components such as the baffle 184. This provides crucial protection for the valuable hybrid material and greatly improves the safety and reliability of the operation.

For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
