Description

Technical Field

[0001] This utility model relates to the technical field of forage processing equipment, specifically a square hay bale baler. Background Technology

[0002] Currently, hay bales come in various forms, including small square bales, large square bales, and large round bales. Small square bales are suitable for small plots, while large square bales are better suited for large areas, facilitating collection and transportation. Large round bales have limited transport capacity and are not suitable for long-distance transport. Small square bales of hay are approximately 30-40 cm (width) × 40-50 cm (height) × 70-100 cm (length), with a single bale typically weighing 15-30 kg. Large square bales of hay are typically 1.1-2.2 meters long, 1.15 meters wide, and 0.8 meters high, with a single bale typically weighing 500-800 kg.

[0003] Currently, large-format hay balers on the market are tractor-tethered and can automatically complete multiple operations such as picking up, chopping, pre-compressing, feeding, compressing, and baling of hay, straw, and other materials in one pass. They offer advantages such as high automation, high efficiency, neat and tight bales, and convenient storage and transportation. However, they are expensive, generally costing between 1.38 million and 1.58 million yuan, and require the purchase of a manufacturer's tractor, which also costs 1 million yuan, bringing the total price to over 2 million yuan. This is too high a cost for most farmers in China, and the subsequent maintenance costs are also too high. Due to the high investment and long payback period, they have not been widely adopted or used in China.

[0004] In China, small square bales are commonly formed by manual picking, stacking, and loading. This is not only inefficient but also leads to a labor shortage and rising labor costs as the workforce ages. There is an urgent need for a square bale baler to replace manual picking of small square bales and stacking them into larger square bales, thereby improving efficiency and saving costs. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, this utility model provides a square bale baler that can pick up, stack, compress, and bale small square bales into large square bales, thereby improving work efficiency and significantly reducing costs.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model is equipped with an angled picker, which can pick up small square bales of grass on the ground and send them to a horizontal transmission device. The horizontal transmission device sends the small square bales of grass to the entrance of the bale collection bin. The bale guide device pushes the small square bales of grass into the bale collection bin. The bale lifting device lifts the small square bales of grass to the top of the bale collection bin and compresses the bales. When the number of small square bales of grass in the bale collection bin reaches a set value, the needle threader assembly and the knotter assembly work simultaneously to tie multiple small square bales of grass into a large square bale of grass. The bale discharge device pushes the large square bale of grass out of the bale collection bin and the large square bale of grass falls to the ground.

[0021] This invention can collect, compress, and bundle small square bundles into larger ones. Combined with a grabber, these larger bundles can be directly loaded onto transport vehicles, facilitating transportation and significantly improving operational efficiency. Furthermore, only one person is needed to complete the picking and bundling operation, greatly reducing labor costs.

[0022] Currently, small square balers are in large-scale production in China at a low cost. These balers can pick up, compress, and bundle crop stalks, hay, and other materials into small square bales. This invention can pick up, stack, compress, and bundle small square bales into large square bales without requiring a high-horsepower tractor; a two-rope tractor is sufficient, saving tractor purchase costs, reducing manual picking time, and improving efficiency. This invention, combined with a small square baler, can meet the basic needs of hay collection and processing in agricultural and livestock production, and its cost is far lower than that of large square balers, showing promising application prospects.

[0023] 2. This utility model's tilting pickup includes a tilting panel, a horizontal panel, a horizontal chain, and an assembly of the tilting chain and a spring-loaded chain. Each of the spring-loaded chain assembly, the tilting chain, and the horizontal chain is equipped with a grass-carrying plate, and the spring-loaded chain assembly is equipped with a spring. When the pickup is towed by a tractor and collides with a bale of grass, the weight of the bale presses down on the spring-loaded chain assembly. Under the reaction force of the spring, the spring-loaded chain assembly exerts an upward force on the bale, lifting the front end of the bale. The spring-loaded chain then carries the bale upward to the tilting panel. The tilting chain moves the bale upward along the tilting panel. When the bale reaches the top, the horizontal chain moves the bale horizontally along the horizontal panel to the collection platform. The grass-carrying plates on the chain of this utility model push the bale along the tilting and horizontal panels. The bale moves on the panels rather than on the chain, avoiding grass falling, rope cutting, and bale scattering, resulting in a low bale loss rate. This invention can not only pick up traditional straw bales (two-strand and three-strand straw bales), but also pick up straw bales in net bags without damage, truly realizing mechanical replacement of manual picking, which not only saves time and effort, but also improves the quality and efficiency of the operation.

[0024] 3. The hay bales of this utility model tilting pickup use a special star-shaped rotating plate, which will not damage the hay bales during transmission.

[0025] 4. This utility model is equipped with a torsion spring guide device to ensure that the bale moves along the panel. When the bale reaches the top, it is driven by the torsion spring guide device to rotate 90 degrees in the direction of travel and be horizontally transported to the platform along the direction of the connecting arm, thus transferring the bale to the platform.

[0026] 5. The bale lifting device of this utility model lifts the bale to the baling chamber formed by the lower baling box and the baling bin through a guided vertical movement; once the baling chamber is filled, it squeezes the bale before it is tied to the larger bale, making the bale tight.

[0027] 6. The bale delivery device of this utility model includes a lower rear door assembly, an upper rear door assembly, and a bale pushing device. After baling, the lower rear door cylinder drives the lower rear door to flip downward and open, while the upper rear door cylinder drives the upper rear door to flip upward and open. At the same time, the bale pushing cylinder drives the bale pushing cylinder to push backward, thereby smoothly pushing the large bale out of the baling bin.

[0028] 7. The knotter assembly and needle threader assembly of this utility model are driven synchronously by a double piston rod cylinder and a transmission assembly to ensure that the needle threading and knotting actions are strictly synchronized, ensuring that the needle threader delivers the rope accurately and the knotter quickly completes the fixing.

[0048] like Figure 1-4As shown, a square hay bale baler includes a chassis assembly 1 and running wheels 2 mounted on the chassis assembly 1, an angle pickup 3, a horizontal transmission device 4, a bale guide device 5, a bale lifting device 6, a needle threader assembly 7, a knotter assembly 8, a bale discharge device 9, and a bale collection bin 10. Two running wheels 2 are mounted on both sides of the rear end of the chassis assembly 1. The front end of the chassis assembly 1 is connected to a tractor, and the equipment is towed by the tractor. The angle pickup 3 is hinged to the chassis 11 and is lowered during operation. Figure 1 The tilt pickup 3 is in the retracted state.

[0049] like Figure 4 , Figure 5 As shown, the chassis assembly 1 includes a chassis 11, a lower bale box 12, and a knotter bracket 13. The lower bale box 12 is a rectangular box and is fixed to the top rear end of the chassis 11. The bale collection compartment 10 is fixed to the top of the lower bale box 12, and the knotter bracket 13 is fixed to the upper front side of the lower bale box 12. The lower front side of the lower bale box 12 is the bale inlet. The front end of the chassis 11 is connected to the tractor.

[0050] like Figure 7 As shown, the tilting pickup 3 is in its lowered working state. The tilting pickup 3 includes a body 31, a spring-loaded chain assembly 32, a tilting chain 33, and a horizontal chain 34. The body 31 has a connecting arm that is hinged to the chassis.

The spring-loaded chain assembly 32, the tilting chain 33, and the horizontal chain 34 are all equipped with grass-carrying plates 37. The spring-loaded chain assembly 32 is equipped with springs. The spring-loaded chain assembly 32 lifts the small square bales from the ground to the tilting panel 35, the tilting chain 33 moves the small square bales up to the horizontal panel, and the horizontal chain 34 transmits the bales to the horizontal transmission device 4.

[0051] The grass-carrying plate 37 is an acute-angled triangular plate, and the grass-carrying plates 37 are evenly distributed and installed on the chain to form a star-shaped rotating plate.

[0052] It also includes a torsion spring guide device 38, which is installed on one side of the inclined panel 35 and the horizontal panel 36. The torsion spring guide device 38 includes a torsion spring 39 and a column 310. The column 310 is vertically fixed to the machine body 31, and the torsion spring 39 is installed on the column 310. The torsion spring guide device 38 ensures that the bale moves along the panel. When the bale reaches the top, it is rotated 90 degrees in the direction of travel by the horizontal chain driven by the torsion spring guide device 38, and is horizontally transported to the horizontal transmission device 4 along the direction of the connecting arm, thus transferring the bale to the horizontal transmission device 4.

[0053] When the equipment collides with a small square bale of hay during its movement, the weight of the bale presses down on the spring-loaded chain assembly 32. Under the reaction force of the spring, the spring-loaded chain assembly 32 exerts an upward force on the bale, lifting the front part of the bale. The spring-loaded chain then drives the bale upward to the inclined chain 33. The upward thrust of the inclined chain 33 moves the bale upward. The chain is slightly higher than the inclined plane and inserts into the bale. Due to the use of a special star-shaped rotating plate, the bale will not be damaged during transmission. When the bale reaches the top, under the action of the torsion spring guide device 38, the horizontal chain 34 rotates 90 degrees in the direction of travel along the connecting arm and conveys the bale to the horizontal transmission device 4, transferring the bale onto the horizontal transmission device 4.

[0054] like Figure 8 As shown, the horizontal transmission device 4 includes a ring chain 41, a driving sprocket 42, a driven sprocket 43, a guide wheel 44, and a tension wheel 45.

[0062] The lower rear door cylinder 91 drives the lower rear door 92 to flip downward and open, the upper rear door cylinder 93 drives the upper rear door 94 to flip upward and open, and the grass pushing cylinder 95 drives the grass pushing frame 95 to rotate, causing the grass pushing frame 95 to push backward, thereby pushing the large bales of grass out of the bale collection bin 10.

[0063] It also includes a baling cylinder 97 and a baling frame 98. The baling frame 98 is hinged to the lower rear door 92. The cylinder of the baling cylinder 97 is hinged to the lower rear door 92. The piston rod head of the baling cylinder 97 is connected to the baling frame 98. The baling cylinder 97 drives the baling frame 98 to rotate, causing the baling frame 98 to push forward. The baling frame 98 is used to fix the bales.

[0064] like Figure 1-11 As shown, the working principle and process of this utility model are as follows:

[0065] 1) The equipment is towed by a tractor. When the equipment collides with a small square bale of hay during its movement, the weight of the bale presses down on the spring-loaded chain assembly 32. Under the reaction force of the spring, the spring-loaded chain assembly 32 exerts an upward force on the bale, lifting the front part of the bale. The spring-loaded chain then drives the bale upward to the inclined chain 33. The upward thrust of the inclined chain 33 drives the bale upward. Due to the use of a special star-shaped rotating plate, the bale will not be damaged during transmission. When the bale reaches the top, it is rotated 90 degrees in the direction of travel by the horizontal chain 34 under the action of the torsion spring guide device 38, and is transported along the direction of the connecting arm to the horizontal transmission device 4, thus transferring the bale to the horizontal transmission device 4.

[0066] 2) The horizontal transmission device 4 is driven by a motor to drive the sprocket chain to the lower front side of the platform hay bales at the hay bale inlet of the hay bale box 12, so as to make room for subsequent hay bales to be loaded. Multiple hay bales are gathered into a row to form the first layer of hay bales.

[0067] 3) The piston rod of the guide cylinder 52 of the bale guide device 5 drives the guide frame 51 to rotate, pushing the first layer of bales into the bottom bracket 62 of the bale lifting device 6 in the lower bale box 12.

[0068] 4) The lifting cylinder 61 of the bale lifting device 6 extends and drives the bottom bracket 62 to rise along the vertical slide 64. After rising to the set height, the pressing cylinder 97 pushes the pressing frame 98 forward, and the pressing frame 98 fixes the bale. The bale is in a suspended state and is the first layer of bale.

[0069] 5) Repeat steps 1) to 3) to transport the second layer of hay bales to the bottom bracket 62. At this time, the first layer of hay bales is above the second layer of hay bales. The baling cylinder 97 pushes the baling frame 98 backward, and the baling frame 98 retracts. At this time, the first layer of hay bales falls on the second layer of hay bales.

[0070] 6) Similarly, when the bales on the bottom bracket 62 reach the set number of layers, the knotter assembly 8 and the needle threader assembly 7 are driven synchronously by the double piston rod cylinder and the transmission assembly 82 to complete the bundling.

[0071] 7) The lower rear door cylinder 91 drives the lower rear door 92 to flip downward and open, the upper rear door cylinder 93 drives the upper rear door 94 to flip upward and open, the grass pushing cylinder 95 drives the grass pushing frame 95 to push backward, pushing the large bales out of the bale collection bin 10, the large bales fall to the ground, realizing the large bales discharge, and completing the operation.

[0072] This invention can pick up, stack, compress, and bundle small square bundles, turning them into large square bundles. Combined with a grabber, the large square bundles can be directly grabbed and loaded onto a transport vehicle, facilitating transportation and greatly improving operational efficiency. Furthermore, only one person is needed to complete the picking and bundling operations, significantly reducing labor costs.

[0073] Currently, small square balers are in large-scale production in China at a low cost. These balers can pick up, compress, and bundle crop stalks, hay, and other materials into small square bales. This invention can pick up, stack, compress, and bundle small square bales into large square bales without requiring a high-horsepower tractor; a two-rope tractor is sufficient, saving tractor purchase costs, reducing manual picking time, and improving efficiency. This invention, combined with a small square baler, can meet the basic needs of hay collection and processing in agricultural and livestock production, and its cost is far lower than that of large square balers, showing promising application prospects.
