Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery. Background Technique

[0002] Crop straw is an important feed resource. Vigorously promoting the utilization of straw as feed not only plays an irreplaceable role in expanding the feed source, reducing grain consumption, and promoting the development of herbivorous livestock such as cattle and sheep. The collection and utilization of crop straw are of great significance for reducing open-air burning of straw, improving air quality, and developing green circular agriculture. The straw baling and wrapping machine can complete the storage and fermentation of crop straw in the first time. While significantly improving efficiency, shortening the harvesting time, and reducing labor intensity, the produced bale can be stacked outdoors for a long time, which is convenient to use. Compared with the traditional cellar storage or tower storage method, it saves a large amount of costs and is conducive to the commercialization and circulation of straw feed.

[0029] The utility model includes a frame 4, a conveyor belt 5 installed on the frame 4, a straw conveyor belt 1, a baling motor 3, and a chain plate conveying motor 13. The baling motor 3 and the chain plate conveying motor 13 are installed on the frame 4. The frame 4 is a frame welded by many horizontal bars and vertical bars. In order to facilitate the installation of some devices, many spaces are reserved. The baling motor 3 and the chain plate conveying motor 13 are installed in these spaces as long as they do not block other work. The conveyor belt 5 is a conveying device. There is a gap in the conveyor belt 5 for loose straw to fall, so that some excess loose materials in the process of conveying round straw will fall to the ground from the gap. The straw conveyor belt 1 is a mechanism for conveying loose materials into the baling mechanism 2, and the loose straw is gradually sent into the baling mechanism 2. The baling motor 3 and the chain plate conveying motor 13 are motors that provide power to the baling mechanism 2 and the conveyor belt 5 respectively.

[0030] The utility model installs a bundling mechanism 2 at the front end of a conveyor belt 5 on a frame 4, and installs a round bale platform support mechanism 6 and a film winding mechanism at the rear end. The upper end of a straw conveyor belt 1 corresponds to a straw inlet of the bundling mechanism 2, and a net winding mechanism 8 is installed on the bundling mechanism 2; a bundling mechanism input pulley 9 and a chain plate conveyor pulley 11 are respectively installed on the motor shafts of a bundling motor 3 and a chain plate conveyor motor 13; see Figure 1 and Figure 2 , the installation sequence of the utility model is as follows: the bulk materials are conveyed to the bundling mechanism 2 through the straw conveyor belt 1 for bundling and winding into a round bale, the round bale is sent to the round bale platform support mechanism 6 through the conveyor belt 5, and the round bale is coated by the film winding mechanism on the round bale platform support mechanism 6 to complete the process.

[0031] Baling mechanism 2: Baling mechanism 2 is composed of a front baling fixed frame 205 and a rear baling movable frame 213. The upper ends of the front baling fixed frame 205 and the rear baling movable frame 214 are connected through a baling frame shaft 211. The bottom ends of the cylinder bodies of the synchronous left cylinder 209 and the synchronous right cylinder 218 are respectively axially connected to the two sides of the front baling fixed frame 205. The top ends of the cylinder plugs of the synchronous left cylinder 209 and the synchronous right cylinder 218 are respectively axially connected to the two sides of the rear baling movable frame 214. A plurality of bottom row sprockets 202 are respectively installed on the lower side of the side of the front baling fixed frame 205 through a plurality of bottom row wheel group shafts 215. The plurality of bottom row sprockets 202 are connected through bottom row wheel group shafts 215. The wheel chain 203 is connected, a coaxial synchronous single-groove lower pulley 201 is installed on the bottom wheel group shaft 215 of the bottom wheel power input sprocket 216, and a coaxial synchronous double-groove lower pulley 204 is installed on the bottom wheel group shaft 215 of the bottom wheel power output sprocket 217; a plurality of top-row sprockets 207 are respectively installed on the upper side of the side of the front frame 205 through a plurality of top-row wheel group shafts 210, and the plurality of top-row sprockets 207 are connected through a top-row wheel chain 208, and a coaxial synchronous double-groove upper pulley 206 is installed on the top-row wheel group shaft 210 of the top-row wheel power input sprocket 228; A plurality of movable frame sprockets 220 are respectively installed on the side of the rear movable frame 213 through a plurality of movable frame wheel shafts 212, and the plurality of movable frame sprockets 220 constitute a movable frame sprocket group, and a movable frame single sprocket 225 is installed through a movable frame single-row wheel shaft 214. A tensioning wheel support plate 222 is installed on the outer end of the movable frame wheel shaft 212 of the top sprocket 221 of the movable frame sprocket group through a bearing, and a tensioning wheel 223 is installed on the other end of the tensioning wheel support plate 222 in an axial manner. A fixed frame single sprocket 224 is installed on the second top-row wheel group shaft 210 on the other side of the fixed frame 205 before baling. All movable frame sprockets 220 and movable frame single sprockets 225 are installed. 5. The fixed frame single sprocket 224, the tensioning wheel 223 and the top sprocket 221 are connected by the wheel chain 219; an assist spring 226 is installed between the top of the tensioning wheel support plate 222 and the shaft at the top of the cylinder plug of the synchronous right cylinder 218; the top row wheel group shaft 210, the movable frame wheel shaft 212 and the movable frame single row wheel shaft 214 are respectively connected to the fixed frame 205 before baling or the movable frame 213 after baling through bearings, and the top row wheel group shaft 210, the movable frame wheel shaft 212 and the movable frame single row wheel shaft 214 inside the fixed frame 205 before baling and the movable frame 213 after baling are all equipped with a baling roller 227 with a spiral pattern on the surface.

[0032] See Figures 3 - 8, the tying mechanism 2 formed by the fixed frame 205 before tying and the movable frame 213 after tying is an opening and closing mechanism. The fixed frame 205 before tying is a fixed half box body, fixedly installed on the frame 4. The movable frame 213 after tying is a movable half box body that rotates around the tying frame shaft 211. In this way, when tying with the internal net winding, the fixed frame 205 before tying and the movable frame 213 after tying are in a closed (sealed) state. After the net winding and tying are completed, the movable frame 213 after tying opens, and the round bale after net winding and packing is discharged onto the conveyor belt 5.

[0033] The synchronous left cylinder 209 and the synchronous right cylinder 218 work synchronously and are used to open and close the movable frame 213 after tying.

[0034] There are two groups of shaft rollers on the fixed frame 205 before tying: the bottom row horizontal roller group, which is composed of the bottom row sprocket 202 (the power input sprocket 216 and the power output sprocket 217 of the bottom row wheel group), the bottom row wheel group shaft 215, and the bottom row wheel group chain 203; the top row roller group, which is composed of the top row sprocket 207 (the power input sprocket 228 of the top row wheel group), the bottom row wheel group shaft 215, and the top row wheel group chain 208. From Figure 3 , Figure 4 it can be seen that this roller group is arranged in an arc shape. From Figure 3 it can be seen that there is a space left at the front end between the bottom row horizontal roller group and the top row roller group. This space corresponds to the loose material inlet, so that the loose material is sent into the cavity formed by the fixed frame 205 before tying and the movable frame 213 after tying by the straw conveyor belt 1 (after the loose material transported to the inside is sufficient for net winding and packing the finished product, a door can be set at the front inlet and closed).

[0035] The input pulley 9 of the tying mechanism is connected to the coaxial synchronous single-groove bottom row pulley 201 through a belt. The two grooves of the coaxial synchronous double-groove bottom row pulley 204 are respectively connected to the coaxial synchronous double-groove top row pulley 206 and the single-groove pulley 10 of the straw conveyor belt through belts. The other groove of the coaxial synchronous double-groove top row pulley 206 is connected to the single-groove pulley 810 of the net winding mechanism through a belt.

[0036] The power input sprocket 216 and the power output sprocket 217 of the bottom row wheel group and the bottom row sprocket 202 are the same sprockets. See Figure 4, they are connected together by the bottom row of pulley chains 203. The end of the bottom row of pulley power input sprocket 216's bottom row of pulley group shaft 215 extends, and a coaxial synchronous single-groove bottom row pulley 201 is installed thereon. Since the coaxial synchronous single-groove bottom row pulley 201 is connected to the bale forming mechanism input pulley 9 by a belt, when the bale forming motor 3 starts, its bale forming mechanism input pulley 9 rotates, and is transmitted to the coaxial synchronous single-groove bottom row pulley 201 through the connecting belt to make it rotate simultaneously. In this way, it will simultaneously drive the bottom row of pulley power output sprocket 217 connected to the coaxial synchronous single-groove bottom row pulley 201's chain (bottom row of pulley power input sprocket 216), all the bottom row sprockets 202, and each sprocket's bottom row of pulley group shaft 215 to rotate simultaneously.

[0037] The outer end of the bottom row of pulley power output sprocket 217's bottom row of pulley group shaft 215 extends, and a coaxial synchronous double-groove bottom row pulley 204 with two belt connecting grooves that rotates synchronously with the bottom row of pulley power output sprocket 217 is installed. One belt groove of the coaxial synchronous double-groove bottom row pulley 204 is connected to the straw conveyor single-groove pulley 10 by a belt, and the power will be input to the straw conveyor single-groove pulley 10. The straw conveyor single-groove pulley 10 is the power shaft of the straw conveyor 1, thus driving the conveyor belt on the straw conveyor 1 to work and conveying the loose materials to the bale forming mechanism 2. The other belt groove of the coaxial synchronous double-groove bottom row pulley 204 is connected to the coaxial synchronous double-groove upper row pulley 206 by a belt. The coaxial synchronous double-groove upper row pulley 206 is installed on the extended section of the end of the top row of pulley power input sprocket 228's top row of pulley group shaft 210. Therefore, when the coaxial synchronous double-groove bottom row pulley 204 drives the coaxial synchronous double-groove upper row pulley 206 to rotate, the top row of pulley power input sprocket 228 also rotates synchronously. Since the top row of pulley power input sprocket 228 and all the top row sprockets 207 are connected by the top row of pulley chains 208, all the sprockets of the top row roller group and the top row of pulley group shafts rotate synchronously.

[0038] See Figure 9 , on the left is the form of the coaxial synchronous double-groove bottom row pulley 204 or the coaxial synchronous double-groove upper row pulley 206, which has two belt grooves side by side; on the right is the form of the straw conveyor single-groove pulley 10, the coaxial synchronous single-groove bottom row pulley 201 or the net winding mechanism single-groove pulley 810, which has only one belt groove.

[0039] There are many identical moving frame sprockets 220 on the bale forming rear moving frame 213. These sprockets form an arc-shaped sprocket group. Each sprocket in the arc-shaped sprocket group has an independent sprocket shaft (moving frame row pulley shaft 212). All the moving frame sprockets 220 and the sprocket shafts form a semi-circular arc (see Figure 5), there is also an independent sprocket (single sprocket 225 on the moving frame) and a sprocket shaft (single-row sprocket shaft 214 on the moving frame) on the side of the moving frame 213 after bundling. Since the chain (row sprocket chain 219) is relatively long between the fixed-frame single sprocket 224 and the lowest moving-frame sprocket 220, it is easy for the chain to become loose and the operation to be unstable. Therefore, this independent sprocket is set to reduce the empty length of the chain, increase the running stability, and at the same time, make the chain avoid the middle part of the gap between the fixed frame 205 before bundling and the moving frame 213 after bundling.

[0040] A fixed-frame single sprocket 224 is installed on the other side of the second sprocket shaft in the bottom of the top row roller group of the fixed frame 205 before bundling. When all the sprockets and sprocket shafts in the top row roller group rotate synchronously, the fixed-frame single sprocket 224 will also rotate simultaneously. In this way, all the sprockets, sprocket shafts in the arc-shaped sprocket group, the single sprocket 225 on the moving frame, and the single-row sprocket shaft 214 on the moving frame are driven to rotate synchronously through the row sprocket chain 219.

[0041] The setting of the tensioner support plate 222 and the tensioner 223: Since the row sprocket chain 219 is relatively long, it is very easy to have problems such as loose chain. Therefore, a tensioner 223 is equipped to increase the tightness of the row sprocket chain 219. From Figure 5 and Figure 7 it can be seen that the tensioner 223 presses on the upper end of the row sprocket chain 219. The tensioner support plate 222 is connected to the sprocket shaft of the top sprocket 221 through a bearing. Therefore, when the top sprocket 221 and the sprocket shaft rotate, the tensioner support plate 222 will not rotate. The tightness of the tensioner support plate 222 and the tensioner 223 is completed through the elastic force of the assist spring 226.

[0042] See Figure 7 and Figure 8 , bundling pressure rollers 227 are installed on all sprocket shafts placed inside the fixed frame 205 before bundling and the moving frame 213 after bundling. In order to facilitate the compaction of the bulk materials in a pile, there are many spiral-like patterns on the surface of the bundling pressure rollers 227. Under the action of the net winding and these patterns, the bulk materials are gradually rolled into a round bale form ( Figure 1 the round bale 18 in

[0043] Net Winding Mechanism 8: There are two side plates 807 of the net winding mechanism, which are fixedly installed at the upper end of the bundling mechanism 2. The single-groove pulley 810 of the net winding mechanism is installed on the shaft of the power roller 803 of the net winding mechanism. The two ends of the shaft of the power roller 803 of the net winding mechanism are respectively installed with two side plates 807 of the net winding mechanism through bearings; there are net roller placement grooves 809 on the two side plates 807 of the net winding mechanism, and the roller shafts at both ends of the net winding roller 808 are placed in the net roller placement grooves 809; there is an auxiliary roller 805 of the net winding mechanism corresponding to the power roller 803 of the net winding mechanism. The two ends of the auxiliary roller 805 of the net winding mechanism are installed on the roller lifting plate 812 through bearings. The two sides of the roller lifting plate 812 are inserted into the longitudinal guiding grooves 813, and the longitudinal guiding grooves 813 are fixed on the side plates 807 of the net winding mechanism. The cylinder body of the roller lifting motor 806 is installed at the upper end of the longitudinal guiding grooves 813, and the piston rod of the roller lifting motor 806 is installed at the upper end of the roller lifting plate 812; a transverse guiding groove 814 is installed at the front end of the side plate 807 of the net winding mechanism. The two ends of the transverse sliding plate 815 are inserted into the transverse guiding groove 814, and the net cutting knife 802 is installed between the two transverse sliding plates 815. The cylinder body of the transverse motor 804 is installed at the outer end of the transverse guiding groove 814, and the piston rod of the transverse motor 804 is connected to the outer end of the transverse sliding plate 815; a cutter docking seat 801 is installed between the two side plates 807 of the net winding mechanism corresponding to the cutting edge of the net cutting knife 802; there is a net winding inlet at the position of the bundling mechanism 2 through the gap 811 between the cutting edge of the net cutting knife 802 and the cutter docking seat 801.

[0044] From Figure 10 It can be seen that the side plates 807 of the net winding mechanism are composed of two left and right sheet plates, which are fixed at the front position of the upper end of the bundling mechanism 2, and other mechanisms such as roller shafts are installed between the two side plates. The net winding roller 808 is an existing roller with net winding. The power roller 803 and the auxiliary roller 805 of the net winding mechanism are longitudinally installed corresponding to each other between the side plates 807 of the net winding mechanism in front of the net winding roller 808. The power roller 803 of the net winding mechanism is a roller that can only rotate and cannot move, and its power is transmitted through the single-groove pulley 810 of the net winding mechanism. The auxiliary roller 805 of the net winding mechanism is a roller that rotates passively (it can only rotate when it contacts the power roller 803 of the net winding mechanism) and can move up and down (the movement is achieved by the operation of the roller lifting motor 806, so that its motor shaft pushes the roller lifting plate 812 to move up and down in the longitudinal guiding groove 813 to complete the contact or separation between the auxiliary roller 805 of the net winding mechanism and the power roller 803 of the net winding mechanism). The net winding conveyed by the net winding roller 808 passes between the auxiliary roller 805 of the net winding mechanism and the power roller 803 of the net winding mechanism. A net cutting mechanism is installed at the front end of the side plate 807 of the net winding mechanism, and the net cutting knife 802 can move horizontally ( Figure 11In the disengaged state, the movement is achieved by the operation of the horizontal motor 804, so that its motor shaft pushes the horizontal slide plate 815 to move horizontally within the horizontal guide groove 814. The horizontal slide plate 815 drives the net-wrapping cutter 802 to gradually approach and cooperate with the cutter docking seat 801, cutting the net-wrapping position between them. After cutting, the horizontal motor 804 moves in the reverse direction, driving the net-wrapping cutter 802 back to the Figure 11 original state). The cooperation between the net-wrapping cutter 802 and the cutter docking seat 801 is similar to the cooperation mode between a kitchen knife and a chopping board. The net-wrapping provided by the net-wrapping roller 808 comes between the auxiliary roller 805 of the net-wrapping mechanism and the power roller 803 of the net-wrapping mechanism, then passes between the net-wrapping cutter 802 and the cutter docking seat 801, and finally enters the bundling mechanism 2 through the net-wrapping inlet at the upper end of the bundling mechanism 2. When all the bundling pressure rollers 227 in the bundling mechanism 2 roll, the straw and the net-wrapping will be mixed and wound together and pressed into a round bale.

A round package platform driving sprocket 607 is installed at the outer end of the round package platform driving shaft 611. The round package platform driving sprocket 607 is connected to the round package platform power sprocket 608 through a chain. The round package platform power sprocket 608 is installed on the motor shaft of the round package platform power motor 601. The round package platform power motor 601 is installed under the round package platform bracket 606. A material roller towing belt 603 with a central depression is installed between the round package platform driving roller 605 and the round package platform driven roller 604; Plastic film cutting devices 602 are installed on both sides of the round package platform bracket 606. A round package platform guard plate 612 is installed on the round package platform bracket 606 between the plastic film cutting devices 602 and the round package platform driving roller 605 and the round package platform driven roller 604; The top end shaft of the piston rod of the round package unloading hydraulic cylinder 609 is installed under the round package platform bracket 606, and the cylinder body shaft of the round package unloading hydraulic cylinder 609 is installed on the frame 4 in a form. One end of the round package platform bracket 606 is connected to the frame 4 at the end of the conveyor belt 5 in a shaft form, and the other end is supported by the round package unloading hydraulic cylinder 609.

[0048] Plastic Film Cutting Device 602: The cutting device fixing frame 60207 is installed on the side of the round package platform bracket 606 through the bolt rod 60208. A cutting device hydraulic cylinder 60201 is installed on the cutting device fixing frame 60207. The front end shaft of the cutting device piston rod 60202 of the cutting device hydraulic cylinder 60201 is connected to a rotating arm 60203. A plastic film pressing roller 60205 is installed at the front end of the rotating arm 60203. The middle part of the rotating arm 60203 is installed at the top of the crank arm at the front end of the cutting device fixing frame 60207 through the rotating arm shaft 60204; A plastic film pressing groove frame 60206 is installed on the crank arm through a bracket. The groove of the plastic film pressing groove frame 60206 corresponds to the plastic film pressing roller 60205. A film cutting tooth knife 60209 is installed on the inner side wall of the plastic film pressing groove frame 60206.

[0049] The film winding mechanism works in cooperation with the round package platform bracket mechanism 6, and both are placed at the conveying end of the conveyor belt 5. That is to say, the conveyor belt 5 conveys the round packages successfully bundled by the bundling mechanism 2 to the round package platform bracket mechanism 6, and while rolling on the round package platform bracket mechanism 6, the plastic film is wrapped around the round package through the film winding mechanism.

[0050] See Figure 12, the winding film mechanism support 14 is a suspended support. A winding net rotating frame 15 is installed on the rotating shaft 17 of the rotating motor 7. When the rotating shaft 17 of the rotating motor 7 rotates, it drives the winding net rotating frame 15 to rotate synchronously with the rotating shaft 17, and the plastic film frames 16 installed at both ends of the winding net rotating frame 15 rotate around the circular wrapping platform on the circular wrapping platform support mechanism 6.

[0051] See Figure 13 , the film roller 1602 in the plastic film frame 16 is an existing plastic grinding roller. The shaft in its center is butted with the film roller shaft 1601, so that the film roller 1602 will rotate around the film roller shaft 1601. Two pressure roller support plates 1604 and two pressure roller support rods 1610 form a pressure support. The pressure of this pressure support is realized by the elastic force of the film roller assistant spring 1609. Under the action of the film roller assistant spring 1609, the surface of the plastic film driving roller 1612 contacts the surface of the film roller 1602. In this way, when the film roller 1602 rotates, it will drive the plastic film driving roller 1612 to rotate at the same time. The rotation of the film roller 1602 is realized by dragging the film on it. The film of the film roller 1602 passes between the plastic film driving roller 1612 and the plastic film driven roller 1611, so that the film will not be scratched or damaged by other components during the running process. The rotation of the plastic film driven roller 1611 is transmitted by the gear meshing of the plastic film driving gear 1614 and the plastic film driven gear 1613.

[0052] See Figure 14 , after the circular package is placed on the material roller towing 603, since the contact parts of both ends of the material roller towing 603 with the circular wrapping platform driving roller 605 and the circular wrapping platform driven roller 604 are higher than the middle part of the material roller towing 603, in this way, the circular package will be stuck on the material roller towing 603 and will not roll down. When the circular wrapping platform power motor 601 is started, the circular wrapping platform power sprocket 608 transmits the power to the circular wrapping platform driving sprocket 607 through the chain. When the circular wrapping platform driving sprocket 607 rotates, the material roller towing 603 will roll around the circular wrapping platform driving sprocket 607 and drive the circular wrapping platform driven roller 604 to rotate at the same time. In this way, the circular package will remain in a rolling state on the material roller towing 603.

[0053] See Figure 15 , the plastic film cutting device 602 has two functions. First, it is responsible for pressing the end of the plastic film on the film roller 1602 before the circular package is wrapped with the plastic film. Second, it cuts the plastic film after the circular package is wrapped with the plastic film. The telescopic movement of the cutting device hydraulic cylinder 60201 drives the rotating arm 60203 and the plastic film pressing roller 60205 to stand upright or lie in the groove of the plastic film pressing groove frame 60206 with the rotating arm shaft 60204 as the axis.

[0054] Process of covering with plastic film: The round bale is transported from the conveyor belt 5 to the roller towing 603. The power motor 601 of the round bale platform operates to always keep the round bale rolling on the roller towing 603. At this time, the plastic film pressing roller 60205 is placed in the groove of the plastic film pressing groove frame 60206 and simultaneously clamps the end of the plastic film. Then, the rotating motor 7 operates, and the net-winding rotating frame 15 drives the plastic film frames 16 on both sides to rotate around the roller towing 603. At this time, while the round bale on the roller towing 603 is rolling, the film of the film roller 1602 on the plastic film frame 16 gradually covers the round bale 18. When it is half-covered, the plastic film pressing roller 60205 is slightly lifted (as long as it does not affect the film winding) to release the clamping pressure on the end of the film. When the plastic film covering is completed, during the rotation gap of the net-winding rotating frame 15, the plastic film pressing roller 60205 continues to be lifted and is basically in a vertical state with the ground. When the unbroken film runs onto the plastic film pressing groove frame 60206, the plastic film pressing roller 60205 quickly presses down until it lies in the groove of the plastic film pressing groove frame 60206. Under the action of the film-cutting tooth knife 60209, the plastic film is torn and disconnected. At this time, the round bale 18 has been covered with plastic film. Then, the round bale unloading hydraulic cylinder 609 contracts, and the front end of the round bale platform support 606 descends, and the covered round bale 18 will roll down to the ground from the front (at this time, the rotating motor 7 stops working. Whether the round bale platform support mechanism 6 stops is not very crucial and can be determined according to the on-site situation).

[0055] The utility model intends to carry out research on straw film-covered green and yellow silage feed production equipment. After the recovered straw is chopped, sprayed with microbial agents, and mixed and stirred, it is extruded into round bales, and then covered with film and sealed, fermented, and stored through an automatic film-winding mechanism. Compared with the traditional green and yellow silage methods of cellar storage or tower storage: mildew, liquid leakage, and feeding losses are all greatly reduced; the storage period is long; the storage is simple, not affected by seasons, sunlight, rainfall, and groundwater levels, and can be stacked outdoors; it is convenient to feed; the costs of building cellars and maintenance are saved; it is easy to transport and commercially circulate.

[0056] The utility model can complete the harvesting, storage, and fermentation of crop straw in the first time. While significantly improving efficiency, shortening the harvesting time, and reducing labor intensity, the produced bale can be stacked outdoors for a long time and is convenient to use. Compared with the traditional cellar storage or tower storage methods, it saves a large amount of costs, and is conducive to the commercialization and circulation of straw feed. The implementation of the utility model also reduces the pressure on the agricultural production environment, improves the straw feed conversion rate, provides high-quality straw feed for the livestock industry, and helps the implementation of the "Straw to Meat" and the construction project of tens of millions of beef cattle.
