[0001] The invention relates to the technical field of agricultural crushing, and in particular to a straw sorting and crushing integrated machine. Background Art

[0002] In agriculture, straw is a byproduct with a huge output. Processing and recycling it can bring great economic benefits.

DETAILED DESCRIPTION

[0053] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0054] Reference Figure 1-28A straw sorting and crushing integrated machine includes: a straw sorting component 1, a conveying component 2, and a crushing component 3; wherein, the feeding end of the conveying component 2 corresponds to the bottom of the straw sorting component 1, and the entrance position of the crushing component 3 corresponds to the discharge end of the conveying component 2; the straw that has been preliminarily processed is evenly conveyed to the crushing component 3 through the conveying component 2, and then the crushing operation is carried out; through the integrated design of straw sorting and crushing, the operation effect is guaranteed to be good and stable.

[0055] In some embodiments, the grass separating assembly 1 includes: a frame, and a collecting hopper 11 located at an upper position of the frame, with an open lower end and provided with a grass separating roller 12 .

[0056] Among them, Figure 1 , 2 , 4, and 7; the frame of the grass-dividing component 1 includes a lower support leg portion and a top frame portion; the collecting hopper 11 is raised as a whole, and the conveying component 2 is placed underneath it; the front and rear side panels of the collecting hopper 11 are inclined panels, and the left and right side panels are arranged in a vertical plate shape in conjunction with the frame structure; at the same time, a power component is arranged on one side of the collecting hopper 11, and one end of the grass-dividing roller 12 passes through the outside to cooperate with the power component for transmission; the other end passes through the outside and is provided with an axle seat and other structures for cooperation.

[0057] In addition, if Figure 4 As shown; multiple reinforcement plates are arranged on the outer side of the aggregate hopper 11 to significantly improve the overall strength and reliability; it can be understood that the reinforcement plates are arranged perpendicular to the wall panels of the aggregate hopper 11, and reinforcement beams are arranged on the frame to provide stronger support for the reinforcement plates.

[0058] In some embodiments, one side of the lower end of the collecting hopper 11 is set as an arc plate 13, and the other side is set as a multi-fold plate 14; at the same time, a hinged plate 15 is swingably set below the multi-fold plate 14; the hinged plate 15 cooperates with the arc plate 13 to form a grass separation outlet.

[0059] like Figure 4 , 6 As shown, the arc plate 13 on one side cooperates with the grass separating roller 12; Figure 6 , 7 As shown, the distance between the multi-fold plate 14 on the other side and the grass separating roller 12 is larger; at the same time, the slope of each panel of the multi-fold plate 14 gradually increases from top to bottom, forming a multi-stage downward expansion shape.

[0060] like Figure 6 As shown; during operation, the grass separating roller 12 is driven to rotate, and the incoming straw is pushed to one side of the multi-fold plate 14; the straw is gradually discharged downward along the various folded surfaces.

[0061] It should be noted that the hinged plate 15 can be set to a fixed state after appropriate adjustment, which will not affect the normal discharging; or, the hinged plate 15 can be set to a movable state, and can swing outward and expand as the feed moves during the discharging process; optionally, a torsion spring, a pressure telescopic rod and other mechanisms are set on the outer side of the hinged plate 15, which pushes it inward under normal conditions and swings it outward when subjected to force; thereby, when the amount of straw added increases, the grass separation outlet below can be appropriately expanded.

[0062] In addition, additional explanation is given for the principle of the grass-separating component 1; when in use, the straw is placed in a disorderly manner into the collecting hopper 11; at this time, with the unidirectional rotation of the grass-separating roller 12, the straw is pushed toward the multi-fold plate 14; in this process, the straw tends to be arranged along the axial direction of the grass-separating roller 12; after reaching the position of the multi-fold plate 14, on the multiple folding surfaces formed, the straw is further adjusted to tend to be along the axial direction of the grass-separating roller 12; at the same time, with the changes in the folding surfaces, the straw is further adjusted again and again; after that, it falls relatively neatly along the folding surfaces and the hinged plate 15 to the conveying component 2 and is sent away.

[0063] In addition, it should be noted that when the hinged plate 15 is in a movable form, it can also better match straws of different diameters; for example, the outer diameter of corn straw is several times that of wheat straw.

[0064] Furthermore, considering that although the cooperation between the collecting hopper 11 and the grass separating roller 12 can achieve a better grass separating effect on the straws, it is inevitable that some straws will not be straightened out; therefore, the structure of the grass separating roller 12 is designed specifically.

[0065] like Figure 5 , 6 As shown, the grass separating roller 12 includes: a central tube 121, a plurality of axially extending mounting plates 122 fixed around the central tube 121, and blades 123 mounted on the mounting plates 122; the central tube 121 with a hollow structure is provided with a larger outer diameter and a larger shifting surface; at the same time, the rotation cooperates with the blades 123, and while shifting the straw, some unstraightened straw is cut into smaller segments and falls between the blades 123, thereby significantly enhancing the grass separating effect.

[0066] In addition, the installation plate 122 is provided to cooperate with the blade 123, which not only facilitates the maintenance and replacement of the blade 123, but also forms a blocking position and a shifting surface at the same time, and together with the blade 123 forms an enlarged shifting surface.

[0067] Preferably, a round hole is opened on the mounting plate 122, and a long hole is opened on the blade 123, so as to facilitate operations such as alignment, installation, and adjustment.

[0068] Furthermore, the blade 123 is mounted on a surface of the mounting plate 122 that is in the same direction as the rotation direction; thus, an enlarged shifting surface and a cutting surface are directly formed by the blade 123 .

[0069] Furthermore, a plurality of reinforcing ribs 124 are provided at one end of the mounting plate 122 away from the blade 123 .

[0070] like Figure 5 As shown; it should be noted that the reinforcing ribs here do not only reinforce the mounting plate 122; they also form small partitions on one side of the mounting plate 122; so that straw is not easy to remain at the connection between the mounting plate 122 and the central tube 121.

[0071] Furthermore, the cross section of the reinforcing rib 124 is triangular; during operation, as the grass separating roller 12 rotates, the reinforcing rib 124 also forms a guiding effect on the straw, further improving the grass separating effect.

[0072] It should be noted that the blade surface of the blade 123 is opposite to the working rotation direction (see Figure 6 , counterclockwise); its cutting effect is very general, because the purpose of setting here is mainly to sort and separate the grass; only for some larger and too messy straws, it can form an appropriate cutting effect.

[0073] In some embodiments, the conveying component 2 is a conveyor belt, and inclined baffles 21 with outwardly expanded tops are arranged on both sides of the conveyor belt.

[0074] like Figure 6 As shown; the inclined baffle 21 prevents the straw from deviating to both sides from the conveyor belt.

[0075] Furthermore, one end of the conveying component 2 is provided with a moving wheel, and the other end is provided with a telescopic support leg, which can facilitate operations such as moving it and adjusting the support.

[0076] In some embodiments, a dust removal component 4 is also provided on the conveying component 2 .

[0077] It should be noted that some metal impurities may be mixed into the straw, which can easily cause damage to the crushing component 3; therefore, an impurity removal component 4 is added to remove some of the mixed metals.

[0078] like Figure 8-11 As shown; the impurity removal component 4 includes: a circulating belt 42 assembled on a bracket body 41, and a plurality of electromagnets 43 arranged at intervals on the circulating belt 42; during operation, the electromagnet 43 located above the conveying component 2 absorbs the mixed metal substances and sends them to the outside.

[0079] like Fig. 9As shown; the bracket body 41 cooperates with the circulating belt 42 to form a trapezoidal operating shape with a larger upper part and a smaller lower part, and its lower end is parallel to and covers and exceeds the width of the conveyor belt; thus, in the operating state of the circulating belt 42, the electromagnet 43 passing above the straw generates an adsorption force, which adsorbs the metal object and drives it to the outside; at this time, when reaching the inclined surface, part of the metal object can fall naturally due to the change of the center of gravity.

[0080] Furthermore, debris buckets are provided below the support body 41 and on both sides of the conveying assembly 2 to collect fallen metal objects.

[0081] Preferably, upper rollers 411 are provided on both sides of the upper end of the bracket body 41, and lower rollers 412 are provided on both sides of the lower end; the circulating belt 42 is sleeved on the upper rollers 411 and the lower rollers 412; and the width between the two lower rollers 412 is greater than the width of the conveyor belt.

[0082] It can be understood that the upper roller 411 and the lower roller 412 are rotatably matched with the bracket body 41, and are externally powered to connect any one or more rollers.

[0083] It should be noted that there is no restriction on the specific form of the bracket body 41; whether it is a rod frame structure or a plate structure, as long as it can cooperate to achieve reliable support for the circulating belt 42. In addition, the overall fixation of the impurity removal component 4 can be achieved by setting additional legs or directly connecting it to the conveying component 2.

[0084] like Figure 8 As shown; the oblique baffle 21 of the conveying assembly 2 is provided with a gap for the circulating belt 42 to pass through; connecting members are provided on both sides of the bracket body 41 and fixed on the oblique baffle 21.

[0085] It is additionally noted that the impurity removal component 4 is perpendicular to the conveying direction of the conveying component 2 so as to adsorb the metal objects and discharge them to the outside and has good stability during the adsorption operation.

[0086] Correspondingly, the electromagnet 43 is arranged along the width direction of the circulating belt 42 with a gap therebetween to adapt to the turning part of the circulating belt 42; as for the connection form between the electromagnet 43 and the circulating belt 42, bolt connection, clamping, gluing and the like can be adopted.

[0087] In some of the above technical solutions, some metal objects in the straw are adsorbed by electromagnetic effect; however, inevitably, how to put the adsorbed metal objects down at a suitable position is still a problem; although relying on the inclined surface of the circulating belt 42 during operation can produce a certain effect, it is not reliable and uncontrollable; therefore, further changes are made to the electromagnetic effect to achieve automatic triggering.

[0088] Specifically, both ends of the electromagnet 43 are respectively extended outward to be provided with electric contacts 431 ; the lower end of the bracket body 41 is provided with a conductive strip 44 that cooperates with the electric contacts 431 ; and the length of the conductive strip 44 covers and exceeds the conveyor belt width of the conveyor assembly 2 .

[0089] Thus, when the electromagnet 43 is located at the lower section, it contacts the conductive strip 44 to realize power supply, generates electromagnetism, and adsorbs metal objects; after leaving the conductive strip 44, the electromagnet 43 loses power supply and no longer generates magnetic force, and the metal objects lose attraction and fall off naturally.

[0090] It can be understood that an electric contact 431 is provided at each end of the electromagnet 43; two conductive strips 44 are provided correspondingly, and an insulating member is provided to isolate the conductive strips 44 from the bracket body 41; and the conductive strips 44 are connected to external electrical energy.

[0091] Furthermore, an electromagnetic plate 45 is disposed at the lower inner portion of the bracket body 41 .

[0092] like Fig. 9 , 11 As shown; adding an electromagnetic plate 45 can better absorb metal objects mixed in the straw; and, after the metal objects are absorbed, due to the presence of a circulating belt 42 between the electromagnetic plate 45, they will not be absorbed on the electromagnetic plate 45, but will still be taken out with the circulating belt 42.

[0093] It should be noted that the magnetic force of the electromagnetic plate 45 can be greater than the magnetic force of the electromagnet 43; some metal objects that are difficult to be adsorbed by the electromagnet 43 are sucked up by the electromagnetic plate 45 and then adsorbed by the electromagnet 43 again, and then transported out; in addition, some metal objects may also be adsorbed by the electromagnetic plate 45, sandwiched between the electromagnets 43, and then transported out.

[0094] It should be noted that the trapezoidal lower end formed by the bracket body 41 and the circulating belt 42 can be set longer; it is best to make the length of the electromagnetic plate 45 larger than the conveyor belt width of the conveying component 2.

[0095] In some embodiments, the impurity removal assembly 4 further includes: a plurality of permanent magnet bars 9 disposed between the inclined baffles 21 .

[0096] like Figure 8 As shown, the electromagnet 43 cooperates with the electromagnetic plate 45 to absorb some metal objects; but the effect is not very good for some tiny metal impurities; therefore, some permanent magnetic bars 9 are provided to perform multi-stage impurity removal.

[0097] It should be noted that the axial direction of the permanent magnet bar 9 is perpendicular to the conveying direction (in a horizontal plane), or horizontally inclined; when vertically coordinated, the permanent magnet bar 9 directly crosses over the conveyor belt of the conveying assembly 2; when inclined, the length of the permanent magnet bar 9 is increased, which can increase the adsorption working surface.

[0098] Furthermore, a clamping seat 91 is provided on the inner wall of the conveying assembly 2 (on the inner wall of the inclined baffle 21 ), and both ends of the permanent magnet bar 9 are placed in the clamping seat 91 .

[0099] It should be noted that the lower end of the permanent magnet bar 9 is higher than the normal material height of the conveyor belt and does not interfere with the straw transportation.

[0100] In addition, it should be noted that the permanent magnetic rod 9 does not have a self-cleaning function, so multiple permanent magnetic rods 9 are provided; some of them can be removed for cleaning without stopping the machine.

[0101] However, this creates another problem; since the amount of metal impurities mixed in the straw is uncertain, it is impossible to know how long it will take for the permanent magnet bar 9 to absorb more metal impurities; it is not necessarily appropriate to rely solely on a fixed time period.

[0102] Therefore, the permanent magnet bar 9 is further designed.

[0103] In simple terms, a load-bearing trigger is designed to determine the operating state of the permanent magnet bar 9 .

[0104] Specifically, a gravity sensor is provided in the card mounting seat 91; by monitoring the gravity change of the permanent magnetic bar 9, a signal is sent outward after reaching a threshold value to remind personnel to operate.

[0105] It is understandable that, for the signal form, it is possible to use sound and light triggering, control system to send information outward, etc.

[0106] It should be noted that the gravity sensor does not need to be in continuous operation; just set a suitable time interval for triggering the sensing.

[0107] In the aforementioned part, the straw was sorted and weeded; next, the straw will be crushed; in order to ensure the straw processing effect and be applicable to a variety of straws, a multi-stage crushing mechanism is designed.

[0108] Specifically, the crushing assembly 3 includes: a material shifting assembly 5, a primary crushing assembly 6, a fine crushing assembly 7 and a material discharging assembly 8 which are arranged in sequence from front to back.

[0109] like Fig.13 As shown, the straw is sequentially fed through the material-selecting component 5, preliminarily crushed by the primary crushing component 6, crushed again by the fine crushing component 7, and then discharged outwardly through the discharging component 8; wherein the discharging component 8 throws the crushed straw upwards.

[0110] In some embodiments, the material diverting assembly 5 includes: a material diverting box 51 with front and rear openings, and a material gathering roller 52 that is cooperatively arranged in the material diverting box 51 and rotates.

[0111] like Figure 12-17 As shown; the front end of the material box 51 is a large opening, which cooperates with the conveying component 2.

[0112] The gathering roller 52 is symmetrically provided with two augers 521 with opposite rotation directions; during operation, the straw is gathered to the middle position; correspondingly, the rear end opening of the material shifting box 51 is a reduced opening at the center position.

[0113] Furthermore, there is a gap between the two end augers 521, and two gear plates 522 are symmetrically arranged in the gap area; wherein the gear plates 522 are perpendicular to the central axis of the material gathering roller 52, and both gear plates 522 pass over the middle position of the material gathering roller 52 from one side.

[0114] During operation, the straw is gathered by the auger 521 and then moved and transported backward by the toothed plate 522 .

[0115] Here we need to combine the previous working form; as mentioned above, the straw is arranged into a form that tends to be along the conveying direction; at this time, when entering the material box 51, it still maintains the general direction unchanged; however, the auger 521 will inevitably produce a certain offset to it; at this time, the role of the tooth plate 522 is expanded; the front end of the tooth plate 522 is evenly arranged teeth; when force is applied to the straw, it cooperates with the rotation of the material gathering roller 52 to convey the straw to the rear end in a relatively straight manner; so that the straw entering the next stage basically remains consistent with the conveying direction; thus, it can be more conducive to subsequent crushing operations.

[0116] Furthermore, a reinforcing plate 523 is provided on the gear shift plate 522 to improve the bearing performance.

[0117] Preferably, the reinforcing plate 523 is a right-angle plate structure, and a discharge hole 5231 is opened on the plate surface to reduce blockage.

[0118] In some embodiments, the shaft of the gathering roller 52 passes through the outside of the material shifting box 51 and is assembled through the swing arm 53; thus, when different straw materials are fed in, the gathering roller 52 can form a certain degree of self-swing.

[0119] Specifically, one end of the swing arm 53 is rotatably assembled with the material shifting box 51 , and the other end is rotatably assembled with the axis of the material gathering roller 52 ; correspondingly, a strip opening for cooperating with the swinging is opened on the material shifting box 51 .

[0120] In addition, it should be noted that gears or pulleys and other structures are provided on the shaft of the material gathering roller 52, which are connected to the power assembly (not shown in the drawings); bearings and other structures are provided on the swing arm 53, and the rotation and swing of the material gathering roller 52 do not cause interference.

[0121] In some embodiments, the primary crushing assembly 6 includes: a large crushing roller 61 and a small crushing roller 62 arranged above the inside of the shell, and a rear pulley 63 and a flat roller 64 arranged below.

[0122] The large crushing roller 61 and the small crushing roller 62 rotate counterclockwise; the rear pulley 63 and the flat roller 64 rotate clockwise; the four work together to transport the straw backwards.

[0123] At the same time, the large crushing roller 61 and the small crushing roller 62 are surrounded by tooth blades 65 extending along the axial direction; a plurality of folding plates 66 connected front and back are surrounded by the rear pull wheel 63; the folding plates 66 form a force application surface for pushing backwards; the coordination of various structures has a good conveying and crushing effect.

[0124] It should be noted that a corresponding driving structure is also provided; in order to better maintain the force balance and reduce the wear of the equipment operation; the power of the large crushing roller 61 and the small crushing roller 62 is set on one side, and the power of the rear pulley 63 and the flat roller 64 is set on the other side.

[0125] like Fig.18 , 19 As shown; a gear box is provided on each side of the primary crushing assembly 6; the corresponding gears assembled on the rear paddle wheel 63 and the flat roller 64 are driven in the same direction through a synchronous gear; at the same time, a transmission shaft extends inward from the gear box and is connected to the gear box on the other side through a universal shaft transmission; in the gear box on the other side, the gears assembled on the large crushing roller 61 and the small crushing roller 62 are driven in the same direction through another synchronous gear.

[0137] Preferably, the tension rod 733 is a telescopic rod or an elastic rod; during operation, it can produce a certain amount of self-adjustment, thereby changing the shape of the front plate 73.

[0138] like Fig.23 , 24 As shown, the strip-shaped wear-resistant block 74 is assembled on the top of the front plate 73, and it can be inspected, maintained and replaced regularly.

[0139] In some embodiments, the discharge assembly 8 includes: two pairs of rollers 81 arranged to rotate in opposite directions inside the shell.
