Description

Technical Field

[0001] This utility model relates to a straw crushing device, and also to a residual film recycling machine equipped with the straw crushing device. Background Technology

[0002] Straw crushing devices are widely used in the straw crushing field, such as in residual film recycling machines, which typically include a crushing device as a pre-processing unit. This utility model also relates to further improvements of the straw crushing, residual film recycling, and baling combined operation machine disclosed in CN120615351A, which uses a synchronous belt for film collection. Further improvements are proposed to address problems encountered during the experimental use of the residual film recycling and baling combined operation machine described in Chinese patent document CN120615351A. Simultaneously, the inventors further investigated other devices equipped with crushing devices for straw crushing to determine the causes of related technical problems.

[0003] Through the inventor's research, it was found that known equipment containing straw crushing devices are all high-speed, high-load mechanisms (the high speed and high load here refer to the operation and load of straw crushing, which are known technologies). The crushing blades are installed on the striking shaft in a predetermined distribution pattern. The wear and damage of blades in different positions usually vary. With the wear and damage of the blades, as well as the influence of debris adhering to the blades, the blade shaft is prone to dynamic imbalance, which generates vibration. This, in turn, induces vibration of the striking device, which may lead to equipment damage, reduced reliability, and reduced service life of the entire equipment.

[0004] To reduce the impact of vibration, the strength and rigidity of relevant parts of the equipment are usually increased. However, this will result in an excessively large total mass of the equipment, which will seriously reduce the economic efficiency of the equipment operation.

[0005] It should be noted that, for example, the working environment of a residual film recycling machine is very harsh, with a lot of dust on site, and there may be stones, wires, etc. in cotton fields. Damaged or deformed blades, as well as uneven adhesion of dust or mud, can all lead to dynamic imbalance. This kind of dynamic imbalance is difficult to solve on site. In other words, dynamic imbalance is often the norm for straw crushing equipment.

[0006] Note: Straw crushing equipment is generally used as a component of agricultural equipment such as harvesters for crushing and returning straw to the field, rather than in applications such as workshops. The operating conditions are highly variable, and the on-site working conditions are generally quite harsh.

[0007] It should be noted that the above background technology is technical information that the inventor has acquired in order to deduce the relevant technical problems or obtained in the process of designing this utility model, and does not mean that the above background technology was already prior art before this utility model application, especially the technical content of the cognition and confirmation of the relevant technical problems.

Detailed Implementation

[0036] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that "machine body" is a general term, primarily used in the embodiments of this utility model as a mounting base for other components on the striking rod device 2. Furthermore, in a residual film recycling machine, there exists a generally constitutive main body, including a portion for mounting the striking rod device 2. In other words, the machine body can also refer to, for example, the basic structure of a residual film recycling machine. In the mechanical field, installation includes direct installation and indirect installation, with indirect installation including but not limited to installation on the machine body via other components. Installation via other components includes dynamic connections and static connections.

[0037] In some embodiments of this invention, the traction unit 1 is used to tow a vehicle, such as a tractor head, for example, a residual film recycling machine, and the power for the residual film recycling machine can come from, for example, the tractor head. In some embodiments, an independent power unit can be provided for the residual film recycling machine. In the embodiments of this invention, the basic structure of the lever device 2 is described in detail, such as the first drive mechanism for driving the cutter shaft 8, without describing its power source or motor. However, it should be understood that, given a defined motion pattern of the cutter shaft 8, driving the cutter shaft 8 can be achieved without creative effort based on existing technology. For example, if the cutter shaft 8 employs simple rotational motion, it can be directly driven by an electric motor, pneumatic motor, or hydraulic motor, or the power from a traction device such as a trailer can be connected by a drive shaft assembly provided on the traction unit.

[0038] In the field of vehicle technology, a defined front and rear are defined. In the embodiments of this utility model, the end where the traction unit 1 is located is the front end, and the end where the impurity removal and residual film recovery unit 3 is located is the rear end. Under these conditions, the front and rear are defined in the embodiments of this utility model. Furthermore, in the field of vehicle technology, under the condition that the front and rear are defined, the left and right are also defined. However, it should be noted that in the embodiments of this utility model, "up," "down," and other terms such as "left," "right," "inner," "outer," "front," and "rear," as well as similar expressions, are for illustrative and explanatory purposes only, and are intended not to mislead those skilled in the art.

[0039] Similarly, statements that are mutually explanatory, such as vertical or horizontal, are also for the purpose of explanation or clarification.

[0040] In addition, in the field of mechanics, it should be known that the front-to-back direction is also called longitudinal, head-to-tail, or length direction, while the left-to-right direction is also called transverse, width direction, or width direction.

[0041] In addition, to facilitate the description of the relationship between one component or component and another component or component shown in the accompanying drawings, spatially relative terms such as "lower," "upper," and similar terms may be used in embodiments of this invention. It should be understood that the spatially relative terms are intended to cover different orientations of the device during use and operation, in addition to those depicted in the accompanying drawings.

[0042] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0043] Furthermore, as a special note, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0044] It should be understood that in the field of mechanics, standard geometric terms are typically used to describe approximate mechanical structures, without implying that the mechanical mechanism possesses the exact geometric characteristics corresponding to those terms. For example, the bolt head of a hexagonal head bolt is actually a hexagonal prism, and the ends of the bolt head are rounded.

[0045] In the embodiments of this utility model, the main purpose of the pulverizing device 2 is to crush, for example, cotton stalks and return them to the field. It includes two parts: crushing the cotton stalks and the discharge direction when returning them to the field. Generally, after the cotton stalks are crushed, the discharge direction is usually backward. However, in the residual film recycling machine, a waste removal and residual film recycling section 3 is provided after the pulverizing device 2. It is necessary to consider the impact of the crushed cotton stalks thrown backward on the residual film recycling.

[0046] Furthermore, from a technical perspective, current impact-bearing devices 2 typically generate significant vibrations, leading to harsher operating environments for machines such as residual film recycling machines. Additionally, traditional impact-bearing devices 2 often use fixed blades, resulting in a rigid impact on the plant. The plant's reaction force against the blades is very large, and the fixed blades lack cushioning, easily causing deformation or damage to the blades and their mounting structure.

[0047] The following will provide a detailed explanation of the relevant content described in the above two paragraphs, and propose solutions in conjunction with the embodiments of this utility model.

[0048] The body of the striking device 2 is usually also a component of the body of a residual film recycling machine, and is generally a beam-shell structure. Without causing motion interference, crossbeams can be installed to improve overall strength, or longitudinal beams can be installed. If the strength and stiffness of the shell component constituting the beam-shell structure meet the design requirements, both crossbeams and longitudinal beams can be omitted. For example, the left wall panel 5 and the right wall panel 12 are usually made of steel plates with a thickness of 8mm or more, which have relatively high stiffness and strength, and can serve as mounting bases for, for example, the cutter shaft 8.

[0049] Accordingly, a left mounting hole is provided on the left wall panel 5, and a right mounting hole is provided on the right wall panel 12. In a preferred embodiment, the two mounting holes adopt a split structure to facilitate, for example, the installation of the cutter shaft 8; in other embodiments, the holes can be directly formed as round holes, installed by through-hole method, and assembled through flanges.

[0050] When using a split structure, a top-bottom split structure is preferred.

[0051] In the embodiments of this utility model, the blade body 9, the blade shaft 8, and the corresponding left and right bearing seats of the striking blade are assembled into an assembly, namely the striking blade assembly. During installation, the striking blade assembly is directly assembled onto the machine body as a whole.

[0052] Accordingly, the punching tool assembly includes the tool shaft 8 and the tool bodies 9 distributed on the tool shaft 8. Regarding the distribution density of the tool bodies 9 on the tool shaft 8 and the assembly method, unless otherwise specified, please refer to the prior art regarding the distribution density, distribution form and assembly method of the tool bodies 9 on the tool shaft 8, which will not be repeated here.

[0053] Accordingly, the support components including, for example, the left bearing housing are collectively referred to as the left support assembly, and the support components including the right bearing housing are collectively referred to as the right support assembly, with the left support assembly and the right support assembly providing portions that mate with the corresponding left mounting holes and right mounting holes.

[0054] Additionally, the two corresponding support assemblies have bearing housings and bearings mounted within the bearing housings for supporting the cutter shaft 8, such as... Figure 3The left bearing 16 and the right bearing 18 are shown in the diagram.

[0055] Furthermore, a left damping sleeve 15 is provided, through which the left support assembly is mounted on the left mounting hole. Correspondingly, a right damping sleeve 19 is provided, through which the right support assembly is mounted on the right mounting hole.

[0056] Regarding the damping materials used in the left damping sleeve 15 and the right damping sleeve 19, if the structure is simply a cylindrical structure, the range of damping materials to choose from is relatively wide. For example, spring steel can be made into a corrugated plate first, and then wound into a cylinder, with the circumference of the cylinder corresponding to the wavelength of the wave.

[0057] Another good option is rubber cushioning material for mechanical equipment, which is currently the most widely used cushioning material in the machinery field, and the selection range is relatively wide, such as natural rubber, styrene-butadiene rubber, neoprene rubber, nitrile rubber, silicone rubber, butadiene rubber, and butyl rubber. Another advantage of using rubber materials is their relative ease of molding, allowing for the creation of features such as flanges. This enables a more reliable connection on the fixed side and achieves better vibration damping and isolation. Specifically, in addition to the vibration damping and isolation performance of the sleeve body, the flange provides more options for fixing it together with the bearing housing and forms vibration damping isolation between the wall panel surface and, for example, the flange of the bearing housing.

[0058] One superior cushioning material for mechanical equipment is ACF (Acoustic Collagen Fluoride), a biomimetic cartilage material that can absorb up to 97.1% of vibrations. This is 3 to 5 times the vibration damping performance of traditional rubber damping materials, and its fatigue resistance is far superior. Although the cost is relatively high, considering both vibration damping performance and service life, ACF material has good application prospects and is already widely used in mechanical equipment. It can be a better choice for the embodiments of this utility model.

[0059] Similar to rubber materials, ACF materials are also easy to manufacture into sleeves and flanges, resulting in better shock absorption performance.

[0060] More specifically, the bearing housing may have a cylindrical outer profile, and the corresponding mounting holes may have a depth comparable to that of the bearing housing, the depth of which is the same as the length of the main body of the bearing housing. The bearing housing has an outer flange, located outside the corresponding wall panel. Bolt holes are drilled on the flange to align with it, and bolts are then used to fix the bearing housing to the corresponding wall panel through the flange. The flange is clamped between the outer wall surface of the wall panel and the flange of the bearing housing, thus forming a second damping pad. Correspondingly, the bearing housing and the mounting space form a first damping pad; the simultaneous placement of the first and second damping pads provides better vibration damping performance.

[0061] As mentioned earlier, the dimensions of the bearing housing determine the depth of the bore, and the size of the bearing housing is determined by the bearing dimensions and the mounting dimensions. Those skilled in the art will have a clear understanding of this, and it will not be elaborated further here.

[0062] Relatively speaking, the hole depth can be smaller than the width of the bearing housing, but the hole depth should not be too small in order to meet the load requirements, and generally should not be less than 75mm.

[0063] The hole depth determines the maximum length of the shock absorber sleeve, but in the preferred embodiment, the length of the shock absorber sleeve is not less than 75mm.

[0064] It should be noted that with the development of technology, new damping materials with better shock absorption performance have emerged, including the aforementioned ACF material, whose cushioning performance is 3 to 5 times that of traditional rubber materials. It can be seen that with the emergence of new material technology, there are lower requirements for the size of damping components. For example, the length of the damping sleeve can be greatly reduced to 30mm. Under the condition that the performance of new materials is determined, the selection of its size specifications will also be predictable.

[0065] Regarding the wall thickness of the shock absorber sleeve, in the embodiments of this utility model, the wall thickness of the rubber shock absorber sleeve currently used in the experiment is 8mm. If a better-performing ACF material is used, a shock absorber sleeve made of ACF material with a wall thickness of 2~3mm can be selected.

[0066] The driving mechanism for the cutter shaft 8 is prior art and has been described previously. In some embodiments, a belt drive mechanism is used to input power. The belt drive mechanism has a certain buffering capacity and is more suitable for applications with harsh working conditions.

[0067] Belt drives can also be replaced by chain drives with flexible components.

[0068] Furthermore, when the power is supplied from the traction unit 1, for example, the power of a locomotive, the power is generally input to the first-stage power shaft of the traction unit 1 via a drive shaft equipped with a universal joint. The power shaft is equipped with a drive pulley, which is connected to the traction unit 1 via a transmission belt. Figure 3 The driven pulley 6 shown forms a belt drive mechanism, thereby forming a first drive mechanism for driving the cutter shaft 8.

[0069] If a hydraulic or pneumatic system is used, the drive shaft can be omitted, and power can be transmitted to the driven object, such as a hydraulic motor or a pneumatic motor, through a hydraulic circuit or pneumatic pipeline.

[0070] The bottom of the striking device 2 is open to directly crush cotton stalks, for example, that are inserted between the left wall plate 5 and the right wall plate 12 of the striking device 2. However, cotton mold recycling machines, for example, usually move by dragging, and cotton fields cannot be guaranteed to be flat. In order to avoid the blades 9 in the striking device 2 from hitting the ground and thereby reduce ineffective hitting and damage to the blades 9, a contour roller 22 is provided on the rear side of the striking blade assembly.

[0071] Figure 9 The structure shown clearly reveals the bottom structure of the striking device. As can be seen from the figure, the contour roller 22 provides a supporting height, thus ensuring an interference-avoiding distance between the striking blade assembly and the ground when the residual film recycling machine is on a flat surface. It should be understood that for the blade body 9, the condition for it to strike the ground is when its sweeping path, driven by the blade shaft 8, comes into contact with the ground. The portion of the blade body 9 corresponding to this sweeping path is obviously a cylindrical surface, which can typically be denoted as the blade tip circle.

[0072] Correspondingly, the height difference between the lower generatrix of the contour roller 22 and the tip circle of the striking blade assembly is 25mm~65mm, that is, the lower generatrix of the contour roller 22 is lower, which can effectively reduce or avoid the probability of the striking blade assembly hitting the ground.

[0073] Regarding the direction of throwing the crushed straw back into the field, if there are no other processing devices in the equipment included in the straw-beating blade assembly, the crushed straw can be thrown directly backward. However, in some embodiments, such as residual film recycling machines, in order to reduce the impact of crushed straw on residual film recycling, a straw-collecting auger assembly 23 is installed on the rear side of the straw-beating blade assembly. This straw-collecting auger assembly 23 is arranged laterally and located on the rear side of the straw-beating blade assembly. After the crushed cotton stalks are thrown backward, they are received by the straw-collecting auger assembly 23 and conveyed to one end of the straw-collecting auger assembly 23.

[0074] Accordingly, the auger assembly 23 includes a front-opening tube housing and a helical rotor installed inside the tube housing. One end of the tube housing is sealed, and the other end forms the auger opening. The shaft of the helical rotor extends from the center hole at the sealed end of the tube housing to connect to a second drive mechanism that drives the helical rotor. The second drive mechanism... Figure 9 The illustrated structure also employs a belt drive mechanism. Under these conditions, the shredded straw is discharged to one side of the threshing device, thereby reducing the impact on residual film recycling.

[0075] If the contour roller 22 is present at the same time, the auger assembly 23 is also arranged laterally, with its longitudinal position behind the contour roller 22. Since the contour roller 22 is relatively low, the crushed straw is usually thrown backward and upward, so the presence of the contour roller 22 does not have a significant impact on the auger assembly.

[0076] exist Figure 10In the illustrated structure, the blade 9 is mounted on the blade shaft 8 via a pin 31 parallel to the blade shaft 8, thus possessing the freedom to rotate around the pin 31. When the blade shaft 8 rotates, the blade 9 extends radially due to centrifugal force and possesses a certain moment of inertia under the influence of the blade shaft 8. When the blade 9 strikes the straw, the reaction force of the straw on the blade 9 causes the blade 9 to rotate in the opposite direction. The blade 9 is relatively less prone to deformation, and the connection between the blade 9 and the blade shaft 8 is not rigid, thereby extending the service life of the connection structure between the blade 9 and the blade shaft 8.

[0077] Furthermore, due to the rotating structure formed by the pin 31 connection, even after the reaction force of the straw is lost, the blade 9 still extends radially under centrifugal force. If the blade 9 is fixedly connected to the blade shaft 8, the fixed structure will deform with increasing usage time, gradually changing the shape of the blade 9 and affecting the crushing efficiency. In contrast, the swing connection method of the blade 9 in the above embodiment of this utility model can more effectively ensure that the crushing efficiency remains at a relatively high level.

[0078] It should be noted that the structure of mounting via pin 31 described above is the preferred embodiment of this utility model. In some embodiments, the implementation method of fixing the cutter body 9 on the cutter shaft 8 can still be selected.

[0079] Furthermore, in some embodiments, in order to reduce the radial length of the cutter body 9 on the cutter shaft 8 and improve the load-bearing capacity, the cutter shaft 8 can be a tube shaft. In other embodiments, based on the same consideration, another form can be used to achieve the function of a tube shaft, and the size of this structure can be relatively larger than that of a tube shaft.

[0080] Accordingly, the cutter shaft 8 includes: Shaft, such as Figure 2 The left shaft 7 and right shaft 11 shown are two relatively short shafts, designed to be as short as possible while still satisfying the requirements for spoke connection. The area where the spokes are located is the part of the cutter shaft 8 used to mount the cutter body 9, denoted as the shaft base.

[0081] In some embodiments, spokes may be provided only at both ends of the shaft base, and the spokes are used to determine the diameter of the shaft base. The spokes located at the ends are referred to as end spokes. At each end of the shaft base, one or two end spokes may be provided. If two end spokes are provided at each end, the distance between the two end spokes at the same end is 0.4 to 1.2 times the diameter of the end spoke.

[0082] In some embodiments, intermediate spokes may also be provided in the remaining portion of the shaft base.

[0083] Furthermore, a cover plate is provided, which is installed on the centrifugal side of the spoke by means of, for example, screw connection, to form a cylindrical structure, referred to as the mounting cylinder.

[0084] Correspondingly, screw holes are provided on the centrifugal side of the middle spoke.

[0085] The screw holes can also be rivet holes, so that the cover plate can be fixed to the spoke plate by riveting.

[0086] Accordingly, the blade body 9 is mounted on the mounting cylinder.

[0087] exist Figure 10 In the illustrated structure, the mounting structure of the cutter body 9 on the cutter shaft 8 includes: Two mounting plates, such as Figure 10 The first mounting plate 25 and the second mounting plate 33 shown are axially opposed to each other on the cutter shaft 8, thus forming a mounting space between the two mounting plates. Pin holes are also provided on both mounting plates.

[0088] Provide a headed pin, such as Figure 10 The pin 31 shown has a lead pin that passes through the pin hole, and the end of the lead pin opposite to its lead has a cotter pin hole; a cotter pin 32 is also provided, which locks the pin 31 in place after it has been inserted. This structure is relatively easy to maintain and facilitates the replacement of the cutter body 9.

[0089] exist Figure 10 In the illustrated structure, the blade body 9 includes two blades, such as... Figure 10 The first side blade 27 and the second side blade 28 shown are opposite each other. They can be connected as one unit or are two relatively independent units, so as to replace them separately rather than as a whole, thereby reducing maintenance costs.

[0090] Furthermore, in Figure 10 In the illustrated structure, both blades include a base plate perpendicular to the axis of the pin hole and an outwardly flared portion connected to the end of the base plate and folded to one side. The outwardly flared portions on the two blades contained in the same blade body 9 are folded in opposite directions, presenting the state shown in the figure.

[0091] exist Figure 10 In the illustrated structure, a reinforcing plate 29 is provided between the base plate and the outward-flaring portion, and the reinforcing plate is located on the outward-flaring side of the outward-flaring portion. The reinforcing plate 29 is connected to the blade by welding.

[0092] The two blades are bonded together on their base plates, resulting in a relatively compact structure.

[0093] In addition, the two mounting plates are subjected to significant impacts during operation. Compared to the maintainability of the cutting blade, the mounting plates are welded to the sheathing plate, thus requiring higher rigidity. Figure 10 As can be seen in the illustrated structure, the two mounting plates are generally channel steel components. Similar steel structural components can also be used. For example, when a channel steel component is formed, the mounting plate includes a web with the pin hole and reinforcing flanges on both sides of the web, and the overall shear section modulus is relatively large.

[0094] As can be seen from the above, the impact on the cutter body is mitigated by the rotation of the pin 31, thereby further reducing vibration.

[0095] Correspondingly, the reinforcing flanges on the two mounting plates fold in opposite directions.

[0096] In some embodiments, side-drum blades are provided on both sides of the lower part of the machine body, such as Figure 2 The left membrane blade 4 and the right membrane blade 13 shown are used to cut the plastic film on the ground, thereby facilitating the recycling of residual film.

[0097] exist Figure 2 In the illustrated structure, the edge membrane blade bends downward and inward, has relatively high rigidity, and is not easily damaged.

[0098] The above description is illustrative in conjunction with the accompanying drawings and is not intended to limit the scope of this utility model. Within the concept of this utility model, the above embodiments or different embodiments can be combined without conflict. Although the utility model has been described in detail in the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
