Description

Technical Field

[0001] The invention relates to the technical field of silage balers, and in particular to a silage square bale compression and wrapping system. Background Art

[0002] At present, corn has been used as feed corn and has become an important raw material for animal fattening. Among them, immature whole corn plants are used as green feed; on the other hand, corn silage is obtained from the whole corn plant in the milk stage and is one of the main types of feed in the world.

[0003] In addition, corn cob silage is used as a basis for pig fattening. Since feed corn is usually grown by specialized farms, fermentation and reuse on farms for animal fattening are often spatially separated, so feed corn must be transported and stored. There are currently three technologies for preserving feed corn.

[0004] The first method is to store feed corn in a high pit plant, load the chopped and kernel-crushed corn into the tower, add additives and compact it to form a tight layer on the surface of the corn, close the environment and prevent fermentation. One problem with this method is that in order to avoid fermentation of silage during operation or before use, only one or two days' worth of silage is taken out from the feed pit plant at a time, which is cumbersome and increases the workload.

[0005] The second method is to compact the chopped feed maize in a bag wrapping machine by means of a pressing plate in an upwardly opened bag, which is suspended in a basket for stability. The disadvantages of this method are that the feed maize may partially expand again when the pressing plate is moved out of the bag after compaction; in addition, the degree of compaction of the feed maize is low because the feed maize is only compacted from one side; in addition, due to the geometry of the bags used, the shape of the compacted feed maize is not optimal, so that the bags cannot be stored in a space-saving manner.

[0006] The third method: In a cylindrical wrapping system with a horizontal axis, the cut and crushed feed corn is rolled into a cylindrical shape with a certain pressure, and then wrapped with mesh and plastic film to form a cylindrical wrapping. The cylindrical wrapping has a low space utilization rate and cannot be stored and transported in a space-saving manner. The transportation cost is relatively high. Summary of the invention

[0007] The invention provides a silage bale compression and wrapping system to solve the technical problems of low compaction degree of silage and low space utilization rate due to the final formed shape existing in the existing wrapping method.

[0008] The technical solution adopted by the present invention is as follows:

[0012] Furthermore, the shape of the push plate is adapted to the cross-sectional shape of the feed bag; multiple door panels are arranged corresponding to multiple surfaces of the feed bag so as to be parallel to the corresponding surfaces on the feed bag after opening, thereby providing auxiliary support for the feed bag that gradually slides out of the forming groove.

[0013] Furthermore, the first coating device includes a hollow cylindrical mounting cylinder, a first driving roller group connected to the mounting cylinder to drive the mounting cylinder to rotate, a first coating roller and a first tensioning roller group rotatably installed in the mounting cylinder; a first plastic film is wound on the first coating roller, and the starting end of the first plastic film is tensioned by the first tensioning roller group for connection with the feed bag; the first driving roller group is used to drive the mounting cylinder to rotate, and then when the feed bag is pushed into the mounting cylinder, the first coating roller rotates around the feed bag to drive the first plastic film to wrap the feed bag along the spiral direction to form a circumferential coating bag.

[0014] Furthermore, the second coating device includes a winding frame rotatably arranged around a vertical axis, a flipping drive mechanism arranged on the winding frame, and a second coating mechanism located outside the winding frame; the flipping drive mechanism is used to support the circumferential coating package that is completely out of the pressing mold and flip the circumferential coating package around the horizontal axis; the second coating mechanism is used to seal and coat the flipped circumferential coating package along the length direction during the process of the winding frame driving the flipping drive mechanism to rotate around the vertical axis, so that the circumferential coating package is formed into a fully coated package.

[0015] Furthermore, the flipping drive mechanism includes two groups of second driving rollers arranged on both sides of the sliding direction of the circumferential coating package, and two groups of second driving rollers for driving the two groups of second driving rollers to rotate respectively; the two groups of second driving rollers are respectively supported on the winding frame and extend along the sliding direction of the circumferential coating package; the circumferential coating package that is completely out of the pressing mold is supported on the two groups of second driving rollers so as to flip around the horizontal axis during the rotation of the two groups of second driving rollers.

The finally formed fully coated bag is compacted and well sealed, which can effectively avoid the fermentation of the silage during storage and transportation. In the present invention, the silage is tightly compacted under the action of the pressing mold, and is sealed and coated under the action of the first coating device and the second coating device, and is finally formed into a cubic bag with a certain length and a polygonal cross-section. Compared with cylindrical bags, cubic bags can be stably and reliably stacked. It not only improves the safety of storage and transportation, but also has high space utilization, effectively saves storage and transportation space, and reduces transportation costs. In addition, due to the cross-winding of the first coating and the second coating, it is possible to peel off the coating and take out part of the silage, while the remaining silage can still maintain its shape and relatively sealed state under the action of the first coating and the second coating, avoiding the fermentation of the silage. This is particularly beneficial for buyers. Compared with storage in a feed pit factory, the maximum single-time removal amount can be significantly reduced, and it can be used as needed without worrying about the fermentation of the remaining silage.

[0035] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0036] Reference Figure 1-69-10, the preferred embodiment of the present invention provides a silage square bale compression and wrapping system, comprising: a pressing mold 1, a first film coating device 3, and a second film coating device 5 arranged in sequence along the running direction of the silage. The pressing mold 1 is used to allow the silage to be compressed to enter therein, and after compressing the entered silage into a feed bag 2 with a certain length along the axial direction and a polygonal cross-section, the feed bag 2 is gradually pushed out toward the first film coating device 3. The first film coating device 3 is located on one side of the feed bag 2 being pushed forward, so as to rotate around the feed bag 2 during the process of the feed bag 2 being pushed forward, so as to seal and coat the outer peripheral surface of the feed bag 2 to form it into a circumferentially coated bag 4. The second coating device 5 is used to receive the circumferential coating package 4 gradually pushed out by the pressing mold 1, and start after the circumferential coating package 4 completely escapes from the pressing mold 1, so that the circumferential coating package 4 revolves around the vertical axis and flips around the horizontal axis, so as to seal and coat the circumferential coating package 4 along the length direction, so that the circumferential coating package 4 is formed into a full coating package 6 with both ends and the outer peripheral surface coated.

[0037] When the silage square bag compression and wrapping system of the present invention is working, first, the external silage to be compressed enters the pressing mold 1 through the feed inlet opened on the pressing mold 1, and under the action of the pressing mold 1, the silage is compressed into a feed bag 2 with a certain length along the axial direction and a polygonal cross-section, and then the feed bag 2 is gradually pushed out toward the first coating device 3 under the action of the pressing mold 1; when the front end of the feed bag 2 moves out of the pressing mold 1, the first coating device 3 starts to rotate around the feed bag 2, so that the feed bag 2 gradually moves forward and is pushed out of the pressing mold 1 under the action of the pressing mold 1, and at the same time, the first coating device 3 rotates around the feed bag 2 to seal and coat the outer peripheral surface of the feed bag 2, so that it is formed into a circumferentially coated bag 4, such as Figure 7 As shown; during the process of the feed bag 2 continuing to be pushed out, the second coating device 5 supports the front end of the coating of the feed bag 2, and after the feed bag 2 completely exits the pressing mold 1 and is completely coated circumferentially to form a circumferentially coated bag 4, the circumferentially coated bag 4 is now supported on the second coating device 5, and the second coating device 5 is started, so that the circumferentially coated bag 4 revolves around the vertical axis and flips around the horizontal axis. During the revolution and flipping of the circumferentially coated bag 4, the film is sealed and coated along its length direction, so that the circumferentially coated bag 4 is formed into a fully coated bag 6 with both ends and the outer circumference coated, as shown Figure 8 As shown, the full coating of a feed bag 2 is completed.

[0038] In the system of the present invention, the silage is fully and tightly pressed by the pressing mold 1. Compared with unilateral compaction, its compaction degree is high, and the pressed feed bag 2 is tightly wrapped by the first coating device 3 in the circumferential coating at the same time as it is pushed out of the pressing mold 1, so as to prevent the compacted feed bag 2 from expanding and improve the pressing effect of the silage. The circumferentially coated bag 4 after circumferential coating is also coated in the length direction by the second coating device 5, so that the length ends of the circumferentially coated bag 4 are also sealed by the coating. The finally formed full-coated bag 6 is compacted and well sealed, which can effectively prevent the silage from fermenting during storage and transportation. In the present invention, the silage is tightly compacted under the action of the pressing mold 1, and is sealed and coated under the action of the first coating device 3 and the second coating device 5, and is finally formed into a cubic bag with a certain length and a polygonal cross-section. Compared with the cylindrical bag, the cubic bag can be stable The silage can be stacked securely and reliably, which not only improves the safety of storage and transportation, but also has high space utilization, effectively saves storage and transportation space, and reduces transportation costs. In addition, due to the cross-winding of the first coating and the second coating, it is possible to peel off the coating and take out part of the silage, while the remaining silage can still maintain its shape and relatively sealed state under the action of the first coating and the second coating, thus avoiding the fermentation of the silage. This is particularly advantageous for buyers. Compared with storage in a feed pit factory, the maximum single removal amount can be significantly reduced, and it can be used as needed without worrying about the fermentation of the remaining silage. The storage form of silage improved by the system of the present invention also attracts users who have given up using stored silage due to restrictions on the use of silage outside the pit factory, thereby expanding the base of potential buyers.

[0039] Alternatively, if Figure 1-2As shown, the pressing mold 1 includes a fixed bottom mold 11, a plurality of movable molds 12 that are movably arranged, a pushing mechanism 13 and a closed door 14. The top of the fixed bottom mold 11 is provided with a concave and transversely extending forming groove 101, and a feed inlet connected to the forming groove 101. The plurality of movable molds 12 are movably arranged in the forming groove 101, and the pushing mechanism 13 and the closed door 14 are relatively arranged at the two ends of the forming groove 101. The forming groove 101, the plurality of movable molds 12, the pushing mechanism 13 and the closed door 14 cooperate to squeeze the silage entering the forming groove 101, so that the silage is formed into a feed bag 2 having a length defined by the spacing between the pushing mechanism 13 and the closed door 14, and a polygonal cross-sectional shape defined by the plurality of movable molds 12 and the forming groove 101. The closed door 14 is also used to open after the feed bag 2 is formed, so that the pushing mechanism 13 gradually pushes the feed bag 2 out of the pressing mold 1 along the forming groove 101 toward the first coating device 3. During the pressing process, the closed door 14 is closed, the silage enters the forming trough 101, and the pushing mechanism 13 is started to slowly push the silage toward the closed door 14, or the pushing mechanism 13 is started again after all the silage of a feed bag 2 is formed and enters the forming trough 101. The pushing mechanism 13 pushes the silage forward, and at the same time, the movable mold 12 also cooperates with the forming trough 101 to press the silage, so that the feed bag 2 is formed under the cooperation of the forming trough 101, the multiple movable molds 12, the pushing mechanism 13 and the closed door 14, wherein the length of the feed bag 2 is limited by the distance between the pushing mechanism 13 and the closed door 14, and the cross-sectional shape of the feed bag 2 is limited by the multiple movable molds 12 and the forming trough 101.

[0040] In this option, if Figure 1 As shown, the forming groove 101 is a "V"-shaped groove, and the number of movable molds 12 is two, so the formed feed bag 2 is a tetrahedral bag; on the one hand, the pressing mold 1 for forming the tetrahedral bag has a simple structure and is easy to process and prepare, and on the other hand, the tetrahedral bag is also easier to stack stably and occupies less space, so it is generally formed into a tetrahedral bag.

[0041] In this option, if Figure 1 and 2 As shown, the push mechanism 13 includes a push plate 131 and a sliding drive member 132 connected to the push plate 131 for driving the push plate 131 to slide. In a specific embodiment of this optional solution, the push mechanism 13 also includes a reinforcing rib 133 connected to the push plate 131 for reinforcing its structural rigidity; the sliding drive member 132 is an existing conventional drive member that can drive the push plate 131 to slide linearly, such as a telescopic cylinder.

[0042] In this option, if Figure 2As shown, the closed door 14 includes a plurality of door panels that cooperate to close the outlet end of the molding groove 101, and a rotating drive member connecting each door panel, one side of each door panel is hinged to the fixed bottom mold 11, and the two ends of the rotating drive member are respectively connected to the corresponding door panel and the fixed bottom mold 11, so as to drive the door panel to rotate to open or close the outlet end of the molding groove 101. During the pressing process of the feed bag 2 in the pressing mold 1, the closed door 14 is closed, and after the pressing is completed, the closed door 14 is opened under the action of the rotating drive member, so that the pushing mechanism 13 gradually pushes the feed bag 2 out of the molding groove 101 along the length direction of the molding groove 101. In the specific embodiment of this optional scheme, the rotating drive member can be a telescopic cylinder.

[0043] Preferably, if Figure 1 As shown, the shape of the push plate 131 is adapted to the cross-sectional shape of the feed bag 2 to more stably push the silage to move. Multiple door panels are arranged corresponding to multiple surfaces of the feed bag 2, so as to be parallel to the corresponding surfaces on the feed bag 2 after opening, thereby providing auxiliary support for the feed bag 2 that gradually slides out of the forming groove 101. Under the action of the push mechanism 13, the front end of the feed bag 2 slides out of the forming groove 101. At this time, the feed bag 2 is auxiliary supported by the opened multiple door panels to prevent the front end of the feed bag 2 from tilting down and expanding and affecting its forming shape, and at the same time, it is also convenient for the first coating device 3 to coat the feed bag 2.

[0044] Alternatively, if Figure 2 and Figure 3 As shown, the first film coating device 3 includes a hollow cylindrical mounting cylinder 31, a first driving roller group 32 connected to the mounting cylinder 31 to drive the mounting cylinder 31 to rotate, a first film coating roller 33 rotatably mounted in the mounting cylinder 31, and a first tensioning roller group 34. A first plastic film 35 is wound on the first film coating roller 33, and the beginning of the first plastic film 35 is tensioned by the first tensioning roller group 34 and is used to connect with the feed bag 2. The first driving roller group 32 is used to drive the mounting cylinder 31 to rotate, and then the first film coating roller 33 rotates around the feed bag 2 during the process of the feed bag 2 being pushed into the mounting cylinder 31, so as to drive the first plastic film 35 to wrap around the feed bag 2 along the spiral line direction to form a circumferential film coating bag 4. In this optional solution, the first driving roller group 32 includes a plurality of first driving rollers that are rotatably arranged, and a driving motor connected to each first driving roller to drive the first driving rollers to rotate. The first driving rollers are connected to the mounting cylinder 31 through gear meshing or contact extrusion. When the driving motor is started, the connected first driving rollers are driven to rotate, and the mounting cylinder 31 is then driven to rotate through the rotation of the plurality of first driving rollers.

[0045] During operation, the mounting cylinder 31 rotates, thereby driving the first coating roller 33 and the first tensioning roller group 34 to rotate synchronously around the center line of the mounting cylinder 31. When the front end of the feed bag 2 is pushed out of the molding groove 101 and enters the multiple door panels, the first plastic film 35 is unfolded and pulled onto the multiple door panels to wrap the door panels. When the feed bag 2 continues to move forward, the first plastic film 35 is also opened to the outside of the feed bag 2. As the feed bag 2 continues to move forward, the first plastic film 35 wrapped on the door panel is pulled to wrap the feed bag 2. During this process, the first tensioning roller group 34 is used to provide constant tensile stress to ensure that the first plastic film 35 is placed in the best position on the feed bag 2. During this period, the feed bag 2 will not expand or decompose again. The feed bag 2 is slowly pushed out of the pressing mold 1 by the pushing mechanism 13 and is circumferentially wrapped by the first plastic film 35, so that it can be completely wrapped by the plastic film.

[0046] Alternatively, if Figure 4-6 As shown, the second film coating device 5 includes a winding frame 51 that is arranged to rotate around a vertical axis, a flipping driving mechanism arranged on the winding frame 51, and a second film coating mechanism 53 located outside the winding frame 51. The flipping driving mechanism is used to support the circumferential film coating package 4 that is completely out of the pressing mold 1, and flip the circumferential film coating package 4 around the horizontal axis. The second film coating mechanism 53 is used to seal and coat the flipped circumferential film coating package 4 along the length direction during the process of the winding frame 51 driving the flipping driving mechanism to rotate around the vertical axis, so that the circumferential film coating package 4 is formed into a full film coating package 6.

[0047] In this option, if Figure 5-6 As shown, the flipping drive mechanism includes two groups of second drive rollers 521 arranged on both sides of the sliding direction of the circumferential coating package 4, and two groups of second drive rollers used to drive the two groups of second drive rollers 521 to rotate respectively. The two groups of second drive rollers 521 are respectively supported on the winding frame 51 and extend along the sliding direction of the circumferential coating package 4. The circumferential coating package 4 completely escaped from the pressing mold 1 is supported on the two groups of second drive rollers 521 so as to flip around the horizontal axis during the rotation of the two groups of second drive rollers 521. In this optional scheme, the second drive roller 521 is used to support the circumferential coating package 4. When the second drive roller is started, such as the drive motor, the connected second drive roller 521 is driven to rotate. Since the circumferential coating package 4 has an arc transition on its edge and has a certain dead weight, when the second drive roller 521 rotates, the circumferential coating package 4 supported thereon can be flipped around the horizontal axis so that the entire end surface of the circumferential coating package 4 can be coated.

[0048] In this option, if Figure 5-6As shown, the winding frame 51 includes a winding platform 511, a rotating rod 512 which is arranged to rotate vertically and the top end of which is fixed to the winding platform 511, and two supports 513 which are arranged on both sides of the sliding direction of the circumferential film package 4 and supported on the winding platform 511. A set of second driving rollers 521 is respectively arranged on the two supports 513. When working, the rotating rod 512 is driven to rotate by the driving motor, thereby driving the winding platform 511 to rotate with a vertical axis, and the flip driving mechanism supported on the two supports 513 also rotates with a vertical axis, and finally drives the circumferential film package 4 to rotate horizontally with a vertical axis, so as to facilitate the subsequent second film coating.

[0049] In this option, if Figure 5-6 As shown, the winding frame 51 also includes two groups of row conveying rollers 514 supported on two supports 513, and the two groups of row conveying rollers 514 extend along the sliding direction of the circumferential film bag 4. The row conveying rollers 514 are used to receive the circumferential film bag 4 that has not been completely pushed out of the pressing mold 1, guide the circumferential film bag 4 to move, and guide the circumferential film bag 4 to be supported on the second driving roller 521 after the circumferential film bag 4 is completely out of the pressing mold 1. During operation, when the front end of the feed bag 2 leaves the pressing mold 1 for a certain distance, under the action of the pushing mechanism 13, the front end of the feed bag 2 covered with the first plastic film 35 is supported on the row conveying rollers 514, and gradually supported on the rear second driving roller 521 under the guidance of the row conveying rollers 514, so as to be turned over later under the action of the second driving roller 521.

[0050] In a specific embodiment of this optional solution, the row conveying roller 514 is connected to a lifting driving member for driving the row conveying roller 514 to lift and lower. When the circumferential coating package 4 is completely out of the pressing mold 1, the row conveying roller 514 gradually descends so that the circumferential coating package 4 is gradually supported on the second driving roller 521. Figure 6 Alternatively, a groove with a gradually deepening depth along the axial direction is provided on the support 513, and the row conveying roller 514 is arranged in the groove, and along the sliding direction of the circumferential coating package 4, the circumferential coating package 4 is first supported on the row conveying roller 514, and then as the height of the row conveying roller 514 decreases, the circumferential coating package 4 is gradually supported on the second driving roller 521 until it is completely supported on the second driving roller 521.

[0051] Alternatively, if Figure 9-10As shown, the second coating mechanism 53 includes a second coating roller 531 and a second tensioning roller group 532 that are rotatably arranged. A second plastic film 533 is wound on the second coating roller 531, and the beginning of the second plastic film 533 is tensioned by the second tensioning roller group 532 and used to connect the circumferential coating package 4, so as to seal and coat the circumferential coating package 4 along the length direction during the revolution of the circumferential coating package 4 about the vertical axis, so that the circumferential coating package 4 is formed into a full coating package 6. During operation, in view of the position of the second coating mechanism 53 relative to the circumferential coating bag 4, when the circumferential coating bag 4 revolves about the vertical axis, the second plastic film 533 can only be wrapped around the half height of the circumferential coating bag 4 along the length direction. Therefore, in the present invention, in order to complete the winding of the entire end surface height of the circumferential coating bag 4, the circumferential coating bag 4 is also flipped around the horizontal axis under the action of the flipping drive mechanism, thereby achieving the coating of the entire end surface height of the circumferential coating bag 4, with complete coating and good sealing of the silage.

[0052] In this optional solution, the first plastic film 35 and the second plastic film 533 are both plastic films with good ductility. When opened, they can be firmly wrapped around the outside of the feed bag 2 through a tensioning device, so that the shape of the feed bag 2 is as stable as possible after coating. The two coatings are cross-wrapped with each other, so the silage has good sealing performance.
