Description

Technical Field

[0001] This invention belongs to the field of straw feed compression technology, and specifically relates to a straw feed stacking compression device and method. Background Technology

[0002] Currently, most straw feed balers employ a compression molding process involving front and rear extrusion, vertical compression, and horizontal ejection. The baler is compressed and ejected in one pass through compression mechanisms in three directions (front, back, and vertical). Due to limitations in road height and width, the overall size of the baler (straw feed compression device) cannot be too large. Furthermore, the space required for the compression mechanism restricts the size of the compression chamber, resulting in small compressed bales (straw compressed bodies). This hinders mechanized operation, leading to high labor intensity and low efficiency. Moreover, the compressed bales are prone to crumbling. Summary of the Invention

[0003] One object of the present invention is to provide a straw feed stacking and compression device, which is provided with a flip-up baling mechanism. During transportation, the baling mechanism flips to the rear side of the compression chamber, which can reduce the transportation width of the device and thus increase the space of the compression chamber.

[0004] Another objective of this invention is to provide a method for stacking and compressing straw feed. Without changing the existing silo volume, the method of multiple feedings and stacking and compressing can achieve large-scale bales of straw feed and ensure that the compressed straw body is not easily scattered after being formed.

[0005] The technical solution provided by this invention is as follows:

[0006] A straw feed stacking and compression device includes:

[0007] frame;

[0008] A compression chamber is fixedly mounted on the frame and arranged longitudinally along the frame; the front end of the compression chamber has a first opening, and the top of the compression chamber has a feed inlet;

[0009] A hopper is fixedly installed above the compression chamber, and the lower end of the hopper forms a discharge port; and the discharge port is selectively connected to the feed port of the compression chamber.

[0010] A compression mechanism is disposed above the frame and arranged longitudinally along the frame;

[0011] A compression pusher plate is disposed in the compression cavity;

[0012] The compression pusher plate can reciprocate longitudinally along the compression cavity under the push of the compression mechanism; when the compression pusher plate moves to the first opening, it can block the first opening.

[0013] A push-bundle mechanism is disposed on one side of the compression cavity and near the rear end of the compression cavity; the push-bundle mechanism is arranged laterally along the compression cavity and is hinged to the compression cavity, so that the push-bundle mechanism can be flipped to the rear end of the compression cavity;

[0014] The pushing and baling mechanism can push the compressed straw body laterally along the compression cavity.

[0015] Preferably, the straw feed stacking and compression equipment further includes: a picking and kneading mechanism, which is fixedly installed below the frame and near the front end of the frame; the picking and kneading mechanism picks up straw from the cultivated land and kneads the straw into crushed straw.

[0016] Preferably, the straw feed stacking and compression equipment further includes: a blower conveying mechanism, which is disposed between the kneading device and the hopper; used to feed the straw crushed by the picking and kneading mechanism into the hopper.

[0017] Preferably, the straw feed stacking and compression equipment further includes: a net winding mechanism, which is located on the other side of the compression cavity and is arranged opposite to the baling mechanism, for winding a baling net around the straw compression body;

[0018] The frame is provided with a winding platform corresponding to the winding mechanism. After the straw compressor is pushed out of the compression cavity, it stays on the winding platform until the next formed straw compressor pushes it off the winding platform.

[0019] Preferably, the compression mechanism includes:

[0020] The first mounting bracket is fixedly mounted on the frame;

[0021] A first hydraulic cylinder is arranged longitudinally along the compression chamber; the cylinder body of the first hydraulic cylinder is fixedly mounted on the first mounting bracket, and the output end of the piston rod is fixedly connected to the compression push plate.

[0022] Preferably, the pushing and bundling mechanism includes:

[0023] The second mounting bracket is disposed on one side of the compression cavity, with one end hinged to the rear end of the compression cavity;

[0024] The second hydraulic cylinder is arranged laterally along the compression chamber, and the cylinder body of the second hydraulic cylinder is fixedly mounted on the second mounting bracket;

[0025] The pusher plate is fixedly connected to the output end of the piston rod of the second hydraulic cylinder;

[0026] The compression cavity has a second opening on both sides corresponding to the push-bundle plate and a third opening corresponding to the wrapping mechanism.

[0027] The pusher plate can enter the compression chamber through the second opening under the push of the second hydraulic cylinder, and move laterally along the compression chamber to push the compressed straw body out from the third opening; when the pusher plate moves to the second opening, it can block the second opening.

[0028] Preferably, a horizontally arranged discharge baffle is provided between the discharge port and the feed port of the compression chamber; one end of the discharge baffle is fixedly connected to the top of the compression push plate;

[0029] When the compression pusher plate moves to the second opening, the discharge baffle blocks the discharge port.

[0030] Preferably, the hopper has a truncated quadrangular structure that is smaller at the top and larger at the bottom; and the size of the feed inlet of the compression chamber is the same as the size of the discharge outlet.

[0031] Preferably, the top of the hopper is provided with a mesh cover, and the inlet of the hopper is opened on one side of the cover.

[0032] A method for stacking and compressing straw feed, using the aforementioned straw feed stacking and compressing equipment, includes:

[0033] Step 1: Obtain the weight of the straw in the silo using sensors;

[0034] Step 2: When the weight of straw in the silo reaches the set threshold, open the discharge port of the silo.

[0035] Step 3: After the straw in the hopper has completely fallen into the compression chamber, the compression mechanism pushes the compression plate to move to the rear end of the compression chamber until it reaches the specified position; at the same time, the hopper begins to store material for the second time.

[0036] During the second material storage process in the silo, the compression mechanism remains in the specified position.

[0037] Repeat steps one through three until the resistance experienced by the compression mechanism reaches the specified value;

[0038] Step 4: The baling mechanism operates, pushing the straw compression body out of the compression chamber.

[0039] The beneficial effects of this invention are:

[0040] The straw feed stacking and compression device provided by the present invention has a baling mechanism with a hinge mechanism. During transportation, the baling mechanism is rotated 180 degrees to reduce the width of the device. When the device is working, it returns to the pushing cylinder position to work, thereby increasing the space (volume) of the compression chamber.

[0041] The straw feed stacking and compression device provided by this invention has a truncated quadrangular structure with a small upper opening and a large lower opening in the hopper, which avoids the chopped straw from swelling and affecting the feeding.

[0042] The straw feed stacking and compression method provided by this invention, without changing the existing silo volume, adopts a method of multiple feeding and stacking compression molding, which can realize the large-scale forming of straw feed and ensure that the formed straw compressed body is not easy to fall apart.

[0043] The straw feed stacking and compression device and compression method provided by this invention can simplify the straw compression mechanism, and achieve a good straw compression effect without setting up compression mechanisms in multiple directions. By simplifying the compression mechanism, more space can be provided for the compression chamber. Attached Figure Description

[0053] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0054] like Figures 1-9 As shown, the present invention provides a straw feed stacking and compression device, including: a straw compression mechanism 1, a picking and kneading mechanism 2, a blower conveying mechanism 3, a hopper 4, a compression cavity 5, a mesh cover 6, a frame 7, a baling mechanism 8, and a netting mechanism 9.

[0055] Multiple wheels 701 are provided under the frame 7 to facilitate the traction and transportation of the straw feed stacking and compressing equipment by vehicles.

[0056] The compression chamber 5 is a rectangular shell, fixedly mounted on the frame 7, and arranged along the longitudinal direction of the frame 7; the front end of the compression chamber 5 has a first opening 501, that is, the first opening 501 is opened facing the front end of the frame 7; the top of the compression chamber 5 has a feed inlet.

[0057] The hopper 4 is fixedly installed above the compression chamber 5, and the lower opening of the hopper 4 forms a discharge port; and the discharge port of the hopper 4 is selectively connected to the feed port of the compression chamber 5.

[0058] The compression mechanism 1 is arranged above the frame 7 along the longitudinal direction of the frame 7; the compression push plate 110 is arranged in the compression cavity 5 and is arranged vertically; wherein, the compression push plate 110 can reciprocate along the longitudinal direction of the compression cavity 5 under the push of the compression mechanism 7; when the compression push plate 110 moves to the first opening 501, it can block the first opening 501.

[0059] like Figure 3-6 As shown, in this embodiment, the compression mechanism 1 includes: a first mounting bracket 101, which is fixedly mounted on the frame 7; and a first hydraulic cylinder 102, which is arranged along the longitudinal direction of the frame 7 (the longitudinal direction of the compression chamber 5); the cylinder body of the first hydraulic cylinder 102 is fixedly mounted on the first mounting bracket 101, and the output end of the piston rod of the first hydraulic cylinder 102 is fixedly connected to the compression push plate 110.

[0060] The baling mechanism 8 is located on the left side of the compression chamber 5, near its rear end. The baling mechanism 8 is positioned laterally along the compression chamber 5 and is hinged to its rear end, allowing it to flip to the rear of the compression chamber 5 during transport. This reduces the width of the equipment during transport, providing more space for the compression chamber 5 and enabling the formation of large bales of straw feed. Specifically, the baling mechanism 8 pushes the compressed straw bales laterally out of the compression chamber 5.

[0061] In this embodiment, the bundling mechanism 8 includes: a second mounting frame 801, which is disposed on the left side of the compression chamber 5, and the right side of the second mounting frame 801 (the side facing the rear end of the frame) is hinged to the rear end of the compression chamber 5 via a hinge 801a; a second hydraulic cylinder 802, which is disposed laterally along the frame, and the cylinder body of the second hydraulic cylinder 802 is fixedly disposed on the second mounting frame 801; and a bundling plate 803, which is fixedly connected to the output end of the piston rod of the second hydraulic cylinder 802. The compression chamber 5 has a second opening 502 on its left side, corresponding to the pusher plate 803; and a third opening 503 on its left side, corresponding to the wrapping mechanism 8. The pusher plate 803, pushed by the second hydraulic cylinder 802, enters the compression chamber 5 through the second opening 502 and moves laterally along the compression chamber 5, pushing the compressed straw (square bale) out through the third opening 503. When the pusher plate 803 moves to the second opening 502, it can seal the second opening 502. Figure 5 As shown, during transportation, the second mounting frame 801, together with the second hydraulic cylinder 802 and the pusher plate 803, is rotated 180 degrees to the rear end of the compression chamber 5 (the rear end of the frame 7) for easy transportation.

[0062] As a further preferred embodiment, an arc-shaped track 710 is provided on the frame 7. The shape of the arc-shaped track 710 corresponds to the movement trajectory of the pushing and bundling mechanism 8 as it rotates. A rotating support wheel 801b is provided below the second mounting frame 801. When the pushing and bundling mechanism 8 rotates, the rotating support wheel 801b moves along the arc-shaped track 710. The arc-shaped track 710 and the rotating support wheel 801b can support the rotation of the pushing and bundling mechanism 8, ensuring that the pushing and bundling mechanism 8 can rotate smoothly. At the same time, it can prevent the pushing and bundling mechanism 8 from deforming due to excessive weight or too many rotations, thereby improving the service life of the pushing and bundling mechanism 8.

[0063] Preferably, a horizontally arranged discharge baffle 103 is provided between the discharge port of the hopper 4 and the inlet of the compression chamber 5. One end of the discharge baffle 103 is fixedly connected to the top of the compression push plate 110. When the compression push plate 110 moves, it drives the discharge baffle 103 to move. When the compression push plate 110 moves to a predetermined (stop) position near the second opening 502, the discharge baffle 103 blocks the discharge port of the hopper 4. A weighing sensor is provided on the discharge baffle 103 to detect the weight of the straw in the hopper 4. By fixing the discharge baffle 103 to the compression push plate 110 and moving the discharge baffle 103 through the compression mechanism 1, the discharge port of the hopper 4 can be opened or closed. This eliminates the need for a separate hopper control mechanism, simplifying the structure and the control program of the equipment.

[0064] As a further preferred embodiment, a serrated first cutter 401 is fixedly installed at the rear end of the discharge port of the hopper 4; a second cutter 111 opposite to the first cutter 401 is installed at the upper end of the compression push plate 110. When the compression push plate 110 moves, the first cutter 401 and the second cutter 111 move relative to each other, which can cut the straw blocking the discharge port of the hopper 4 and ensure the smooth movement of the compression push plate 110.

[0065] The picking and kneading mechanism 2 is fixedly installed below the frame 7 and near the front end of the frame 7. For example... Figure 7 As shown, in this embodiment, the picking and kneading mechanism 2 includes a picking roller 201, multiple rows of hammer claws 202, and a kneading and chopping mechanism 203. Multiple hammer claws 202 are arranged circumferentially along the picking roller 201, with multiple hammer claws in each row spaced axially along the picking roller 201. Hammer claws in adjacent rows are positioned relative to each other to ensure effective picking and improve efficiency. When the picking roller 201 rotates, it drives the hammer claws 202 to rotate, picking up the straw from the cultivated land and feeding it into the kneading and chopping mechanism 203. A blower conveying mechanism 3 is provided on each side of the chopping mechanism 203. The blower conveying mechanism 3 has a curved conveying cylinder 301, with the upper end of the conveying cylinder 301 close to the feed inlet of the hopper 4. The blower's hoisting mechanism feeds the chopped straw into the hopper 4 via the conveying cylinder 301. The two blower conveying mechanisms 3 improve the straw conveying efficiency, thereby increasing the overall efficiency of the compression equipment.

[0066] Preferably, the top of the hopper 4 is provided with a mesh cover 6, the lower end of which is connected to the main body of the hopper 4. The hopper inlet 601 is located on the left side of the mesh cover 6. There are two hopper inlets 601, which correspond one-to-one with the outlets of the two conveying cylinders 301. The mesh cover 6 facilitates straw ash removal.

[0067] like Figure 8 As shown, as a further preferred embodiment, the inlets 601 of the two hoppers are at different heights, and correspondingly, the outlet heights of the conveyor cylinders 301 are also different. This arrangement allows the chopped straw to smoothly enter the hopper 4, preventing interference between the material flows entering through the two conveyor cylinders 301, which could prevent some chopped straw from entering the hopper 4.

[0068] like Figure 9 As shown, as a preferred embodiment, the hopper 4 has a truncated pyramidal structure with a smaller top and a larger bottom, making the discharge port size of the hopper 4 larger than the horizontal cross-sectional size of the hopper above the discharge port; and the size of the inlet of the compression chamber 5 is the same as the size of the discharge port of the hopper 4. By setting the hopper 4 with an inverted truncated pyramidal structure, the chopped straw is prevented from bulging at the discharge port, thus avoiding affecting the discharge.

[0069] The wrapping mechanism 9 is located on the right side of the compression chamber 5 and is positioned opposite the baling mechanism 8. It is used to wrap the compressed straw with baling netting. A wrapping platform is provided on the frame 7 corresponding to the wrapping mechanism 9. After the compressed straw is pushed out of the compression chamber 5, it remains on the wrapping platform until the next compressed straw pushes it off. A cutting mechanism 10 is provided on one side of the wrapping mechanism 9. The cutting mechanism 10 is used to cut the baling netting after wrapping is completed. The wrapping mechanism 9 is prior art and will not be described in detail here.

[0070] In the straw feed stacking and compression equipment, both the picking and kneading mechanism 2 and the blower conveying mechanism 3 are powered by a tractor.

[0071] The present invention also provides a method for stacking and compressing straw feed, comprising:

[0072] Step 1: Obtain the weight of the straw in the silo using a weighing sensor.

[0073] Step 2: When the weight of straw in the silo reaches the set threshold, open the discharge port of the silo.

[0074] Step 3: After the straw in the hopper has completely fallen into the compression chamber, the compression mechanism pushes the compression plate to move towards the rear end of the compression chamber to compress the straw until it reaches the specified position; at the same time, the hopper begins a second filling process. During the second filling process, the compression mechanism remains at the specified position, achieving long-term pressure maintenance of the compressed straw and preventing the straw from unbundling.

[0075] Repeat steps one through three until the resistance encountered by the compression mechanism reaches the specified value. At this point, the density of the compressed straw meets the requirements.

[0076] Step 4: The baling mechanism operates, pushing the straw compression body out of the compression chamber.

[0077] In this embodiment, the working process of the straw feed stacking and compression equipment is as follows: the straw on the cultivated land is picked up and crushed into shredded straw by the picking and crushing mechanism 2, and then conveyed to the silo 4 by the blower conveying mechanism 3. When the weight of the straw in the silo 4 reaches the specified weight, the weighing sensor located on the unloading baffle 103 sends a signal, and the piston rod of the first hydraulic cylinder 102 retracts, causing the compression push plate 110 to retract to the first opening 501, sealing the first opening 501; the shredded straw in the silo 4 falls into the compression chamber 5, and after the material has been completely discharged, the first hydraulic cylinder 102... 02. The straw is then pushed again. The piston rod of the first hydraulic cylinder 102 stops after reaching the designated position. At this time, the hopper 4 performs a second material filling. When the material in the hopper 4 reaches the designated weight, the weighing sensor sends a signal, and the first hydraulic cylinder 102 works again for a second push. This process is repeated multiple times until the resistance value experienced by the piston rod of the first hydraulic cylinder 102 reaches the set value (determining that the bale has reached the required density). At this time, the second hydraulic cylinder 802 works, pushing the bale onto the winding platform. The winding mechanism 9 and the cutting mechanism 10 cooperate to complete the winding. During the operation of the compression device 1, the previously completed straw compression body (bale) remains on the winding platform until the next compressed straw body (bale) pushes it out of the winding platform. The previous straw compression body blocks the third opening 503 on the compression cavity during the compression process of the next compressed straw body, which plays an auxiliary role in the straw compression and shaping.

[0078] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made.
