Description

Technical Field

[0001] The utility model relates to the field of baling equipment, in particular to a baling mechanism and a harvesting and baling all-in-one machine. Background Art

[0002] Alliums are a traditional perennial herbaceous crop that plays an important role in agriculture, animal husbandry, and medicine. Many species in this genus are edible, and some, such as garlic, scallions, and leeks, have long been widely cultivated as vegetables. In recent years, domestically grown leeks and other Allium crops, including scallions, have seen a continuous increase in exports, with exports steadily expanding into the international market. This has led to a growing demand for mechanized production of these crops in the domestic market. Compared to other root vegetables, such as potatoes and radishes, the development of specialized machinery for Allium crops has been slow and underdeveloped.

[0003] Across the tens of thousands of hectares of leek cultivation in China, most harvesting is done manually, with little use of machinery. Harvesting typically accounts for 50% of the entire leek production process, undoubtedly the most labor-intensive and time-consuming step. This overreliance on manual labor significantly increases the overall cost of leek harvesting, hindering the further development of the leek and other allium crops industry chain.

[0004] Currently, most allium harvesters on the domestic market are semi-automatic, with relatively backward technology and average performance. Harvesters also have the problem of loose knots. Utility Model Content

[0045] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

The use of "first" or "second" is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of the indicated technical features, or implicitly indicating the order of the indicated technical features.

[0048] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0049] Reference Figures 1 to 6 As shown, the first embodiment of the present invention provides a baling mechanism, which includes: a base 100 , a tightening ring 200 , a baling ring 300 , a switching assembly 400 , a conveying assembly 500 and a fixing assembly 600 .

[0050] In this embodiment, the base 100 is a mounting member, which may be in the shape of a box. The tightening ring 200 passes through two opposite sides of the box. The baling ring 300, the switching assembly 400, the conveying assembly 500, and the fixing assembly 600 are all disposed within the base 100. Alternatively, the base 100 may be in the shape of a frame to support the tightening ring 200.

[0051] The constriction ring 200 is annular, with its outer circumference connected to the base 100, and its inner circumference forming a constriction channel 210. The constriction ring 200 may also be in other shapes, such as a rectangular shape, but has a cylindrical constriction channel 210. The constriction ring 200 has a constriction channel 210 for constricting materials. The constriction channel 210 is used to accommodate materials. For example, after a certain number of leeks are cut or a certain weight is reached, the leeks are loaded into the constriction channel 210 to bundle the leeks to form a bundle for subsequent sorting and transportation. The specific loading process of the leeks can be manual or automatic. The constriction channel 210 includes a constriction ring surface and a baling ring surface. The constriction ring surface is used to constrict the material, and the baling ring surface has an inlet and outlet 211 for communication with the outside world. The baling ring surface can be divided into a first ring surface and a second ring surface. After the leeks are loaded into the constriction ring 200, the center of the leeks aligns with the baling ring surface, allowing the baling mechanism to baling the leeks in the middle, making the baling more secure. As another embodiment, the ends of the leeks can be aligned with the baling ring surface, and the baling mechanism can baling and securing the leeks at the ends.

[0052] The baling ring 300 is annular, but the axial length of the constricting ring 200 is greater than that of the baling ring 300. The baling ring 300 is completely located within the constricting channel 210, allowing the leeks to pass through the constricting channel 210. The baling ring 300 includes a main ring portion 310 and an abutment portion 320 connected to one end of the main ring portion 310. The main ring portion 310 is annular, and the outer circumference of the main ring portion 310 and the outer circumference of the abutment portion 320 are both spaced apart from the inner circumference of the constricting channel 210. After the outer circumference of the main ring portion 310 and the inner circumference of the constricting channel 210 are spaced apart, a gap is formed between the main ring portion 310 and the constricting channel 210 to accommodate the passage of a baling strap. It should be noted that the baling strap is flat and generally thin. The radial dimension of the gap along the constricting channel 210 is sufficient to allow the baling strap to pass through within its thickness, thereby guiding the shape of the baling strap. The abutment portion 320 is in the form of an arcuate sheet or a flat sheet. It can be directly welded to the main ring portion 310 or integrally formed. The abutment portion 320 and the notch are sequentially arranged along the circumference of the baling ring 300. The central angle of the abutment portion 320 generally does not exceed 180°. The smaller the central angle of the abutment portion 320, the greater the space for the baling band to move during baling, resulting in a better bundling effect for the leeks. Furthermore, the smaller the central angle of the abutment portion 320, the smaller its size, which can reduce its structural strength. A suitable balance between bundling effect and structural strength can be achieved based on practical needs. The abutment portion 320 can be aligned with the inlet / outlet 211 along the radial direction of the constriction channel 210, allowing the abutment portion 320 to align with one end of the baling band, facilitating securement of the end of the baling band. The baling ring 300 has a first position and a second position.

[0053] The switching assembly 400 is transmission-connected to the baling ring 300 and is used to drive the baling ring 300 to switch to the first position or the second position along the axial direction of the bundling channel 210. In this embodiment, the switching assembly 400 can be of various types and only needs to meet a certain linear travel, for example, a telescopic lever, a screw slider structure, and a crank slider structure in which the slider performs linear motion.

[0054] The conveying assembly 500 is used to convey the strap toward the inlet and outlet 211 or to retract the strap. It should be noted that, unlike conventional flexible ropes, the strap itself has a certain degree of rigidity. In other words, even when the strap is extended, it can remain basically straight. Therefore, as long as the conveying assembly 500 conveys the extended strap toward the inlet and outlet 211, the strap can be inserted into the inlet and outlet 211 by virtue of its own rigidity.

[0055] The fixing assembly 600 is arranged outside the convergence channel 210. The fixing assembly 600 includes a fixing portion 610 aligned with the inlet and outlet 211 along the radial direction of the convergence channel 210. The fixing portion 610 can be inserted into the inlet and outlet 211 and abut against the outer peripheral surface of the abutting portion 320; after being inserted into the inlet and outlet 211, the fixing portion 610 can abut against the abutting portion 320 to fix one end of the strapping belt.

[0056] The baling ring 300 is configured as follows: in the first position, the main ring portion 310 is aligned with the baling ring surface, and an annular baling space is formed. The conveying assembly 500 conveys one end of the baling strap toward the inlet and outlet 211, and the baling strap wraps around the baling ring 300 along the baling space. After wrapping around the baling ring 300, one end of the baling strap returns to the position of the inlet and outlet 211, and a portion of one end of the baling strap is located between the abutment portion 320 and the inlet and outlet 211 along the radial direction of the converging channel 210. Under the drive of the switching assembly 400, the baling ring 300 is 0 switches to the second position, the abutting portion 320 is aligned with the inlet and outlet 211, part of the strap is aligned with the abutting portion 320 along the radial direction of the constriction channel 210, and the other part is aligned with the notch portion. The fixing portion 610 and the abutting portion 320 clamp one end of the strap together, and the conveying assembly 500 retracts the strap. The portion of the strap aligned with the notch portion will retract toward the center of the constriction channel 210 and tighten the leeks. At the same time, the leeks will also exert a reaction force on the strap. When the stress of the strap binding the material reaches the preset stress, the binding is completed.

[0057] It is worth noting that when the baling ring 300 is in the first position, an annular baling space is formed by the gap between the main ring portion 310 and the closing channel 210. When the conveying assembly 500 conveys the baling strap, the baling strap will pass through the inlet and outlet 211 of the closing ring 200 and enter the baling space. Guided by the inner circumference of the closing channel 210, the baling strap will wrap around the outer circumference of the baling ring 300 in a full circle, and one end of the baling strap will be located at the position of the inlet and outlet 211 again. Then, the switching assembly 400 drives the baling ring 300 to move axially along the closing channel 210 to the second position. When the baling ring 300 is in the second position, the main ring portion 310 moves along the closing channel 210. The channel 210 is axially misaligned with the strapping band, and the outer circumferential surface of the main ring portion 310 will not block the contraction of the annular strapping band, while the abutting portion 320 is aligned with the inlet and outlet 211 and also aligned with the strapping band. By the radial movement of the fixing portion 610 along the constriction channel 210, the fixing portion 610 and the abutting portion 320 clamp one end of the strapping band together, and the one end of the strapping band is clamped and fixed. At this time, the conveying assembly 500 contracts the strapping band, which will reduce the inner diameter of the ring formed by the strapping band, thereby tightening the material in the constriction channel 210 until the internal stress of the strapping band reaches the preset stress. The material can be tightly bound with the preset stress, so that the material bundling effect is better.

[0058] Reference Figure 3and Figure 4 As shown, in some specific embodiments of the present invention, the conveying assembly 500 includes at least one pair of clamping wheel assemblies, and the clamping wheel assemblies include a first clamping wheel 510 and a second clamping wheel 520 that are arranged opposite to each other on the outer circumference. The first clamping wheel 510 and the second clamping wheel 520 are used to clamp and convey the strapping belt; wherein the clamping wheel assembly is configured such that the rotation directions of the first clamping wheel 510 and the second clamping wheel 520 are opposite.

[0059] In this embodiment, the strap is flat, and the clamping wheel assembly is used to clamp the strap along its thickness. Specifically, the first clamping wheel 510 and the second clamping wheel 520 rotate in opposite directions, allowing the strap to move in the same direction. If the strap is conveyed in the counterclockwise direction of the first clamping wheel 510 and the clockwise direction of the second clamping wheel 520, then the strap is retracted in the clockwise direction of the first clamping wheel 510 and the counterclockwise direction of the second clamping wheel 520, and vice versa.

[0060] Reference Figure 3 and Figure 4 As shown, in some specific embodiments of the present invention, the clamping wheel group includes a first transmission gear 530, a second transmission gear 540 and a clamping drive source, the first transmission gear 530 is coaxially fixedly connected to the first clamping wheel 510, the second transmission gear 540 is coaxially fixedly connected to the second clamping wheel 520, the first transmission gear 530 is engaged with the second transmission gear 540, the clamping drive source is transmission-connected to the first transmission gear 530, and is used to drive the first transmission gear 530 to rotate around the axis of the first transmission gear 530.

[0061] It is worth noting that using a single clamping drive source to achieve counter-rotation of the first clamping wheel 510 and the second clamping wheel 520 results in lower operating costs. In this embodiment, the clamping drive source is a motor, which is in transmission connection with the first transmission gear 530. The motor drives the first transmission gear 530 to rotate. The first transmission gear 530, through meshing force, causes the second transmission gear 540 to rotate in opposite directions, thereby causing the first clamping wheel 510, which is fixedly connected to the first transmission gear 530, and the second clamping wheel 520, which is fixedly connected to the second transmission gear 540, to rotate in opposite directions.

[0062] As another embodiment, the first clamping wheel 510 may be driven by a separate motor, and the second clamping wheel 520 may be driven by a separate motor, and the two motors may be controlled by a driver to achieve reverse rotation.

[0063] Reference Figure 3 、 Figure 4 and Figure 6As shown, in some specific embodiments of the present invention, the fixing assembly 600 includes a slip ring 620 connected to the fixing part 610, a rotating rod 630 whose outer circumference is threadedly connected to the inner circumference of the slip ring 620, and a fixed driving source that is transmission-connected to the rotating rod 630. The fixed driving source is used to drive the rotating rod 630 to rotate. The rotating rod 630 is arranged radially along the convergence channel 210, and the slip ring 620 can only move axially along the rotating rod 630 to drive the slip ring 620 to move axially along the rotating rod 630.

[0064] In this embodiment, the slip ring 620 and the rotating rod 630 form a lead screw slider structure. The lead screw slider structure is a common structure in the mechanical field that converts rotational motion into linear motion. The specific structure of the lead screw slider structure will not be described in detail. Specifically, the slip ring 620, driven by the rotating rod 630, moves along the axial direction of the rotating rod 630, thereby driving the fixed portion 610 to move along the axial direction of the rotating rod 630, that is, along the radial direction of the constriction channel 210. The fixed portion 610 is inserted into the inlet 211 along the radial direction of the constriction channel 210, and abuts the abutment portion 320, thereby clamping one end of the strapping tape together with the abutment portion 320.

[0065] As another embodiment, the fixing portion 610 may also be driven by other linear motion mechanisms, such as a telescopic lever, a crank slider mechanism, and the like.

[0066] Reference Figure 1 and Figure 2 As shown, in some specific embodiments of the present invention, the baling mechanism further includes: a stop assembly 700, the stop assembly 700 includes a stopper 710 capable of opening or closing the convergence channel 210, the convergence channel 210 has a feed port, the feed port, the baling ring surface and the stopper 710 are sequentially arranged along the axial direction of the convergence channel 210; wherein the stopper 710 is configured to: stop one end of the material when closing the convergence channel 210; and transport the material along the axial direction of the convergence channel 210 when opening the convergence channel 210.

[0067] It is worth understanding that, by stopping one end of the leek in the convergence channel 210 through the stopper 710, the position of the leek relative to the convergence channel 210 is fixed in the convergence channel 210. According to the position of the leek in the convergence channel 210, the bundling position of the leek can be set at different positions along the axial direction of the convergence channel 210 according to actual needs, so as to bundle the leek at different positions, thereby facilitating the control of the bundling position of the leek.

[0068] In this embodiment, after the leeks are mature, their length is basically fixed. According to the average length of the leeks, the baling ring surface and the stopper 710 are spaced apart along the axial direction of the bundling channel 210. The spacing distance is basically half of the average length of the leeks, so that the baling ring surface bundles the middle part of the leeks, and the bundling ring surface is also divided into two by the baling ring surface.

[0069] Reference Figure 1 and Figure 2 As shown, in some specific embodiments of the present invention, the stop assembly 700 also includes a gear condition 720 connected to the stop member 710 and a stop drive source 730 engaged with the gear condition 720. The gear condition 720 is radially penetrated through the base 100 along the convergence channel 210. The stop drive source 730 is transmission-connected to the gear condition 720 to drive the gear condition 720 to move radially along the convergence channel 210 and enable the stop member 710 to close or open the convergence channel 210.

[0070] In this embodiment, the rack member 720 is disposed through the base 100 and is guided by the base 100 to move radially along the convergence channel 210. The stopper drive source 730 includes a motor and a gear disposed on the motor output shaft. The gear and the rack member 720 are meshed radially along the convergence channel 210. When the gear rotates, the meshing force of the teeth causes the rack member 720 to move radially along the convergence channel 210, thereby causing the stopper 710 to close or open the convergence channel 210. An escape channel is provided within the base 100 to avoid the stopper 710, allowing the stopper 710 to completely move radially along the convergence channel 210 to the outside of the convergence channel 210.

[0071] In addition, the convergence channel 210 is tilted toward the ground, the feed port is located at the high end of the convergence channel 210, and the stopper 710 is located at the low end of the convergence channel 210. The leeks in the convergence channel 210 can slide to the ground under the action of their own gravity.

[0072] Reference Figure 3 As shown, in some specific embodiments of the present invention, the strapping mechanism further includes: a hot melt assembly and a cutting assembly 800. The hot melt assembly is used to hot-melt one end of the strapping band and the overlapping portion of the strapping band. The cutting assembly 800 is provided between the fixing assembly 600 and the conveying assembly 500. The cutting assembly 800 is used to cut the strapping band between the hot melt position and the conveying position.

[0073] It is worth noting that the fixing portion 610 and the contact portion 320 clamp one end of the strap, but not exactly at the end. Instead, they clamp the strap at a position farther back, allowing a portion of the strap to extend beyond the clamping position between the fixing portion 610 and the contact portion 320. The hot melt assembly aligns this portion with the loop portion of the strap, overlapping them, and then hot melts the strap to form a closed loop, thus sealing the loop strap. Subsequently, the cutting assembly 800 cuts the straight portion outside the loop strap, separating the loop strap from the conveyed straight strap, thereby completing the bundling of individual leeks.

[0074] In this embodiment, after the hot melt assembly and the cutting assembly 800 complete their actions, the stop drive source 730 drives the stop member 710 to open the convergence channel 210, allowing the leeks to escape from the convergence channel 210. After the bundle of leeks escapes, the stop member 710 closes the convergence channel 210 again to allow a new bundle of leeks to enter.

[0075] Reference Figure 6 As shown, in some specific embodiments of the present invention, the baling ring 300 includes a support ring portion 330 , the outer circumference of the support ring portion 330 is slidably connected to the inner circumference of the bundling channel 210 , and one end of the support ring portion 330 is connected to the main ring portion 310 .

[0076] It is worth noting that the support ring portion 330 is used to support the main ring portion 310 and keep the relative position of the main ring portion 310 and the constriction channel 210 fixed to form an annular gap of substantially fixed size, so that the movement of the strapping band in the annular gap is more stable.

[0077] In this embodiment, the support ring portion 330 is fixedly connected to the main ring portion 310 as a whole. Alternatively, the main ring portion 310 can move relative to the support ring portion 330 along the axial direction of the constriction channel 210, so that the main ring portion 310 can move completely into the support ring portion 330. When part of the strap is in contact with the outer circumference of the main ring portion 310, the axial movement of the main ring portion 310 along the constriction channel 210 will drive the strap to move axially along the constriction channel 210. At this time, the end surface of the support ring portion 330 will abut against one side of the strap, making it difficult for the strap to move axially along the constriction channel 210 with the main ring portion 310. The strap is sequentially located on the strapping ring surface, which facilitates separation of the strap from the main ring portion 310 and subsequent bundling of leeks with the strap.

[0078] Reference Figure 5As shown, in some specific embodiments of the present invention, the switching assembly 400 includes a switching turntable 410, a switching transmission rod 420, a switching rod 430 and a switching drive source 440. The switching turntable 410 is transmission-connected to the switching drive source 440 and rotates under the drive of the switching drive source 440. One end of the switching transmission rod 420 has a waist-shaped hole. The switching turntable 410 has a first rotating portion located at the edge of the switching turntable 410. The first rotating portion is transmission-connected to the waist-shaped hole. The other end of the switching transmission rod 420 is transmission-connected to one end of the switching rod 430. The switching rod 430 is limitedly connected to the base 100 and is limited by the base 100 to only move along the axial direction of the convergence channel 210. The other end of the switching rod 430 is connected to the baling ring 300.

[0079] It is worth noting that the switch dial 410, the switch transmission rod 420, and the switch rod 430 form a crank slider structure. The positional constraints of the switch rod 430 and the base 100 allow the switch rod 430 to move only in a linear motion, thus enabling the use of the crank slider structure in linear motion. It should be noted that the first rotating portion is located at the edge of the switch dial 410. The first rotating portion and the switch dial 410 form an eccentric mechanism, which drives the switch transmission rod 420 through the eccentric mechanism, thereby causing the switch rod 430 to move linearly.

[0080] The second embodiment of the present invention provides an all-in-one harvester and baler, which includes: a baling mechanism according to the first embodiment of the present invention.

[0081] It is worth noting that the harvester-baler uses the baling mechanism of the first embodiment to achieve automated baling and better baling effect. The other structures of the harvester-baler are common knowledge to those skilled in the art and will not be described in detail here.

[0082] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
