Description

Technical Field

[0001] The present invention relates to the technical field of silage feed, and more particularly to an all-round compression device for silage feed, a wrapping device having the same, and a wrapping method. Background Art

[0002] Silage feed is a commonly used processing and modulation method for improving the palatability of forage, enhancing the digestibility of livestock, and preserving nutritional value. Compared with hay and other forages, silage feed contains more effective nutritional components and has higher economic benefits.

[0003] However, the silage bales produced by the compression device of the existing silage wrapping equipment are small in volume and low in density, and the weight of the silage bales cannot be adjusted in real time according to requirements, which cannot meet the needs of different users.

[0004] Therefore, it is an urgent problem for those skilled in the art to develop an all-round compression device for silage feed with high working efficiency and high bale density, a wrapping device having the same, and a wrapping method. Summary of the Invention

[0005] In view of this, the present invention provides an all-round compression device for silage feed with high working efficiency and high bale density, a wrapping device having the same, and a wrapping method.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] An all-round compression device for silage feed, comprising:

[0008] A compressor frame, in which a compression chamber is provided;

[0009] A compression piston, which includes a left compression piston and a right compression piston. The left compression piston and the right compression piston are symmetrically arranged on both sides of the compression chamber and are connected to the compressor frame; the compression plates at the movable ends of the left compression piston and the right compression piston move along the two side walls of the compression chamber respectively;

[0010] A push piston, which is connected to the compressor frame;

[0011] A door, which is hinged to the compressor frame. The push piston and the door are symmetrically arranged at the front and rear ends of the compression chamber; the push plate at the movable end of the push piston, the compression plates of the left compression piston and the right compression piston, the door, and the side wall of the compression chamber form a compression cavity for compressing silage feed.

[0012] The beneficial effects of adopting the above technical solution are as follows. By setting a symmetrical left compression piston, a right compression piston, a pushing piston, and a silo door, a complete compression chamber is formed, which can compress the silage feed in all directions, making the density of the silage bale higher and the structure more compact.

[0013] Preferably, a storage bin is arranged above the compression bin, and the storage bin is connected to the compressor frame. Arranging a storage bin above the compression bin can store the silage feed in advance, realize continuous feeding, reduce the feeding time of the equipment, and improve production efficiency.

[0014] Preferably, a cloth auger is installed on the side wall of the storage bin. The setting of the cloth auger can ensure that the silage feed can fall into the compression bin evenly.

[0015] Preferably, a proximity switch for detecting the position of the pushing piston is arranged on the compressor frame. The proximity switch can accurately detect the position of the pushing piston, realize precise positioning of the movement of the pushing piston, and improve the automation degree and operation reliability of the equipment.

[0016] A wrapping equipment with a silage all-round compression device includes:

[0017] A feeding device, the feeding device is connected to the compressor frame, and the material of the feeding device is conveyed into the storage bin;

[0018] A power device, the power device is arranged below the feeding device; the power device provides power for the operation of the left compression piston, the right compression piston, the pushing piston, the silo door, and the cloth auger;

[0019] A longitudinal film wrapping device, the longitudinal film wrapping device is connected to the compressor frame and is located on one side of the compressor frame where the silo door is arranged;

[0020] A horizontal film wrapping device, the horizontal film wrapping device is connected to the longitudinal film wrapping device and is located at one end of the longitudinal film wrapping device away from the silo door; after the compressed silage is longitudinally wrapped, it enters the horizontal film wrapping device for horizontal film wrapping.

[0021] The beneficial effects of adopting the above technical solution are as follows. The wrapping equipment combines a silage all-round compression device, and through the coordinated work of the feeding device, the power device, the longitudinal film wrapping device, and the horizontal film wrapping device, an automated production process for silage from feeding, compression to wrapping is realized.

[0022] Preferably, the power unit includes: a power frame, an electric motor, a gearbox, a hydraulic pump, and a speed control valve group; the electric motor, the gearbox, the hydraulic pump, and the speed control valve group are all connected to the power frame; the output end of the electric motor is connected to the input end of the gearbox, the output end of the gearbox is connected to the hydraulic pump, and the hydraulic pump is connected to the speed control valve group. With this design of the power unit, through the cooperation of the electric motor, the gearbox, the hydraulic pump, and the speed control valve group, stable and reliable power support can be provided for the entire equipment. The size and speed of the power output can be flexibly adjusted according to different working requirements to meet the operation needs of components such as the left compression piston, the right compression piston, the pushing piston, the bin door, and the feeding auger, ensuring that all components of the equipment can work coordinately and efficiently, and improving the adaptability and operation efficiency of the equipment.

[0023] Preferably, the gearbox has two input ends and two output ends; the two input ends of the gearbox are respectively connected to the electric motor and an external power device; the hydraulic pump includes: a first hydraulic pump and a second hydraulic pump; the two output ends of the gearbox are respectively connected to the first hydraulic pump and the second hydraulic pump. The gearbox having two input ends and two output ends can be connected to the electric motor and an external power device simultaneously, increasing the choice of power sources for the equipment, making the equipment more flexible in different working environments and not restricted by a single power source.

[0024] Preferably, a clutch is connected between the electric motor and the gearbox.

[0025] Preferably, a weighing sensor is provided at the bottom of the horizontal film winding device. By providing a weighing sensor at the bottom of the horizontal film winding device, the weight of the silage bale can be monitored in real time, and the position of the compression piston can be adjusted according to the weight feedback, thereby realizing the dynamic adjustment of the weight of the silage bale.

[0026] The wrapping method of a wrapping equipment with a silage all-round compression device includes the following operating steps:

[0027] S1. Start the electric motor or the external power device, and the gearbox drives the first hydraulic pump and the second hydraulic pump to start, providing power for the entire equipment; the feeding device conveys the silage to the storage bin through a conveyor belt, and the feeding auger in the storage bin rotates to spread the silage entering the storage bin evenly and then drops it into the compression bin;

[0028] S2. After the compression bin is filled with silage, the feeding auger stops rotating; at this time, the feeding device continues to convey the silage and temporarily stores and piles up the silage in the storage bin;

[0029] S3. When loading the compression bin, the left compression piston and the right compression piston are both in their initial positions. After the compression bin is filled with silage, start the left compression piston and the right compression piston to simultaneously compress downward rapidly from the initial position. When the left compression piston and the right compression piston move to the 0 position of the compression bin, the left compression piston stops compressing, the compression speed of the right compression piston decreases, and it continues to compress. When the right compression piston reaches the set overpressure value, the right compression piston reduces its speed again and slowly retracts to the 0 position of the compression bin.

[0030] S4. When the left compression piston and the right compression piston both stop at the 0 position of the compression bin, open the bin door. The pushing piston slowly pushes out the square silage bale in the compression bin. At the same time, the longitudinal film winding device rotates to axially wind and wrap the silage bale exposed outside the compression bin with silage film. When the pushing piston completely pushes the silage bale out of the compression bin, the axial film winding of the silage bale is completed, and the silage bale falls above the horizontal film winding device.

[0031] S5. After the silage bale falls above the horizontal film winding device, the pushing piston quickly retracts into the compression bin, and the bin door closes. When the proximity switch detects that the pushing piston has retracted to the initial position, the left compression piston and the right compression piston start to retract rapidly.

[0032] S6. After the silage bale falls above the horizontal film winding device, the weighing sensor under the horizontal film winding device feeds back the weight of the silage bale. When the weighed weight is greater than the required value, when the left compression piston and the right compression piston retract, they will retract to the initial position close to the 0 position of the compression bin. At this time, the inlet of the compression bin decreases, the volume of the compression bin decreases, the silage entering the compression bin decreases, and the weight of the compressed and formed silage bale drops to the required value. When the weighed weight is less than the required value, the left compression piston and the right compression piston will retract to the initial position far from the 0 position of the compression bin, the inlet of the compression bin increases, the volume of the compression bin increases, the silage entering the compression bin increases, and the weight of the compressed and formed silage bale rises to the required value. When the left compression piston and the right compression piston quickly retract to the set initial position, the cloth auger starts to rotate, and the silage in the storage bin falls into the compression bin, reducing the feeding time.

[0033] After the silage bale falls above the horizontal film wrapping device, the horizontal film wrapping device rotates, and the silage bale rolls on the horizontal film wrapping device; the horizontal film wrapping device wraps the two end faces of the silage bale with silage film to complete the all-round and dead-angle-free film wrapping; after the horizontal film wrapping is completed, the horizontal film wrapping device flips to unload the silage bale with the film wrapped.

[0034] As can be seen from the above technical solutions, compared with the prior art, the present invention discloses a full-round compression device for silage, a wrapping equipment with the same, and a wrapping method, and the beneficial effects are as follows:

[0035] (1) The design of the symmetric compression piston and the full-round compression chamber can compress the silage evenly and efficiently, significantly increase the density of the bale, and reduce the looseness phenomenon;

[0036] (2) Through the feedback of the weighing sensor and the dynamic adjustment of the compression piston, the weight of the bale can be accurately controlled to meet the needs of different users and improve the standardization degree of the product;

[0037] (3) This equipment can continuously feed materials during the compression and film wrapping process, reduce the feeding time, and improve the operation efficiency; moreover, the operation site is flexible and not restricted by the power source. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0059] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0060] The embodiment of the present invention discloses a comprehensive compression device for silage feed, including:

[0061] The compressor frame 31 is provided with a compression chamber 32 inside.

[0062] The compression piston includes a left compression piston 33 and a right compression piston 34. The left compression piston 33 and the right compression piston 34 are symmetrically arranged on both sides of the compression chamber 32 and are connected to the compressor frame 31. The compression plates at the movable ends of the left compression piston 33 and the right compression piston 34 move along the two side walls of the compression chamber respectively.

[0063] The pushing piston 35 is connected to the compressor frame 31.

[0064] The bin door 36 is hinged to the compressor frame 31. The pushing piston 35 and the bin door 36 are symmetrically arranged at the front and rear ends of the compression chamber 32. The pushing plate at the movable end of the pushing piston 35, the compression plates of the left compression piston 33 and the right compression piston 34, the bin door 36, and the side walls of the compression chamber 32 form a compression cavity for compressing silage. The compression cavity is a square cavity. By compressing with the left compression piston 33 and the right compression piston 34, high-density silage bales can be obtained, and the density can be automatically adjusted in real time according to the target value of the density and weight of the silage bales.

[0065] To further optimize the above technical solution, the left compression piston 33 is driven by two hydraulic cylinders; the right compression piston 34 is driven by three hydraulic cylinders; the pushing piston 35 is driven by two-stage hydraulic cylinders; the two hydraulic cylinders driving the left compression piston 33, the three hydraulic cylinders driving the right compression piston 34, the two-stage hydraulic cylinders driving the pushing piston 35, and the hydraulic motor driving the feeding auger 38 to rotate are all powered by the first hydraulic pump 25 and the second hydraulic pump 26.

[0066] To further optimize the above technical solution, during compression, the left compression piston 33 is driven by two hydraulic cylinders, and its position is measured by a wire rope sensor. The left compression piston 33 is not responsible for the final density of the silage bale, so the pressure is relatively small and it can be driven by two hydraulic cylinders. Also, since the compression end position of the left compression piston 33 does not exceed the 0 position of the compression chamber, it is ensured by measuring the position with one wire rope sensor. The right compression piston 34 is driven by three hydraulic cylinders, and its position is measured by two wire rope sensors. The right compression piston 34 needs to exceed the 0 position of the compression chamber and requires a higher pressure, so it is driven by three hydraulic cylinders. Exceeding the 0 position of the compression chamber is to ensure that the silage bale has sufficient density and prevent the silage bale from rebounding and resulting in a decrease in density and irregular shape after leaving the compression chamber. Also, since the right compression piston 34 needs to return from below the 0 position of the compression chamber, for safety reasons, the position of the right compression piston 34 is measured by two wire rope sensors to ensure accuracy.

[0067] To further optimize the above technical solution, the pushing piston 35 is driven by two-stage hydraulic cylinders. A displacement sensor measures the stroke, and a proximity switch determines the position. When the first-stage hydraulic cylinder pushes the pushing piston and the silage bale out of the compression chamber, a large pressure is required, and the first-stage hydraulic cylinder is relatively large, which is not convenient for installation and use. However, the two-stage hydraulic cylinders can push the silage bale above the horizontal film wrapping device 5. The silage bale no longer suffers from the huge frictional force brought by the compression chamber, and the two-stage hydraulic cylinders are small and convenient for installation. When the pushing piston 35 is pushed out, a displacement sensor measures the pushing stroke to ensure the accurate position of the bale being pushed out. A proximity switch ensures that when retracting, the two-stage hydraulic cylinders drive the pushing piston 35 back to the zero position of the pushing piston.

[0068] To further optimize the above technical solution, a storage bin 37 is provided above the compression chamber 32, and the storage bin 37 is connected to the compressor frame 31.

[0069] To further optimize the above technical solution, a feeding auger 38 is installed at the side wall of the storage bin 37. As Figure 5 、 Figure 9 shown, the feeding auger 38 is installed at a position slightly above the middle of the storage bin 37, and can spread the centrally conveyed silage evenly and drop it into the compression chamber 32.

[0070] To further optimize the above technical solution, a proximity switch for detecting the position of the pushing piston 35 is provided on the compressor frame 31.

[0071] A wrapping equipment with a full-direction silage compression device includes:

[0072] A feeding device 1, the feeding device 1 is connected to the compressor frame 31, and the material of the feeding device 1 is conveyed into the storage bin 37;

[0073] A power device 2, the power device 2 is arranged below the feeding device 1; the power device 2 provides power for the operation of the left compression piston 33, the right compression piston 34, the pushing piston 35, the bin door 36, and the feeding auger 38;

[0074] A longitudinal film wrapping device 4, the longitudinal film wrapping device 4 is connected to the compressor frame 31 and is located on one side of the compressor frame 31 where the bin door 36 is provided;

[0075] A horizontal film wrapping device 5, the horizontal film wrapping device 5 is connected to the longitudinal film wrapping device 4 and is located at one end of the longitudinal film wrapping device 4 away from the bin door 36; the compressed silage enters the horizontal film wrapping device 5 for horizontal film wrapping after longitudinal film wrapping.

[0076] To further optimize the above technical solution, the power unit 2 includes: a power frame 21, an electric motor 22, a gearbox 23, a hydraulic pump, and a speed control valve group 24; the electric motor 22, the gearbox 23, the hydraulic pump, and the speed control valve group 24 are all connected to the power frame 21; the output end of the electric motor 22 is connected to the input end of the gearbox 23, the output end of the gearbox 23 is connected to the hydraulic pump, and the hydraulic pump is connected to the speed control valve group 24.

[0077] To further optimize the above technical solution, the gearbox 23 has two input ends and two output ends; the two input ends of the gearbox 23 are respectively connected to the electric motor 22 and an external power device; the hydraulic pump includes: a first hydraulic pump 25 and a second hydraulic pump 26; the two output ends of the gearbox 23 are respectively connected to the first hydraulic pump 25 and the second hydraulic pump 26. The external power device can be a tractor. Both the tractor and the electric motor can be used as power sources, enabling the device to be unrestricted by the power source and making the working site more flexible; the first hydraulic pump 25 and the second hydraulic pump 26 for oil supply are both gear pumps, with stable oil supply, small impact, less heat generation, and low energy consumption. During operation, when the electric motor 22 is the power source, the electric clutch 27 extends to tension the belt, and the electric motor 22 drives the first hydraulic pump 25 and the second hydraulic pump 26 to supply oil through the gearbox 23; when the tractor is selected as the power source, the electric clutch 27 retracts, and the tractor drives the first hydraulic pump 25 and the second hydraulic pump 26 to supply oil through the gearbox 23.

[0078] To further optimize the above technical solution, whether the first hydraulic pump 25 and the second hydraulic pump 26 output is controlled by the speed control valve group 24; the speed control valve group 24 has three switches, which respectively control the first hydraulic pump 25 to output alone, the second hydraulic pump 26 to output alone, and the first hydraulic pump 25 and the second hydraulic pump 26 to output simultaneously. The movement of the entire device is supplied with oil by the first hydraulic pump 25 and the second hydraulic pump 26; when the cloth auger 38, the left compression piston 33, the right compression piston 34, the pushing piston 35, the longitudinal film winding device 4, and the horizontal film winding device 5 need to move quickly, the first hydraulic pump 25 and the second hydraulic pump 26 supply oil simultaneously; when the cloth auger 38, the left compression piston 33, the right compression piston 34, the pushing piston 35, the longitudinal film winding device 4, and the horizontal film winding device 5 need to move at medium speed, the first hydraulic pump 25 supplies oil alone; when the cloth auger 38, the left compression piston 33, the right compression piston 34, the pushing piston 35, the longitudinal film winding device 4, and the horizontal film winding device 5 need to move slowly, the second hydraulic pump 26 supplies oil alone.

[0079] To further optimize the above technical solution, a clutch 27 is connected between the electric motor 22 and the gearbox 23.

[0080] To further optimize the above technical solution, a weighing sensor is provided at the bottom of the horizontal film winding device 5.

[0081] The wrapping method of a wrapping device with a full - range compression device for silage feed includes the following operation steps:

[0082] S1. Start the motor 22 or an external power device. The gearbox 23 drives the first hydraulic pump 25 and the second hydraulic pump 26 to start, providing power for the whole device. The feeding device 1 conveys the silage feed into the storage bin 37 through the conveyor belt. The cloth auger 38 in the storage bin 37 rotates to spread the silage feed entering the storage bin 37 evenly and then drops it into the compression bin 32;

[0083] S2. After the compression bin 32 is filled with silage feed, the cloth auger 38 stops rotating. At this time, the feeding device 1 continues to convey the silage feed and temporarily stores and piles it up in the storage bin 37;

[0084] S3. When loading the compression bin 32, both the left compression piston 33 and the right compression piston 34 are in the initial position. After the compression bin 32 is filled with silage feed, start the left compression piston 33 and the right compression piston 34 to simultaneously compress rapidly downward from the initial position. When the left compression piston 33 and the right compression piston 34 move to the 0 - position of the compression bin, the left compression piston 33 stops compressing, and the compression speed of the right compression piston 34 decreases and continues to compress. When the right compression piston 34 reaches the set over - pressure value, the right compression piston 34 reduces the speed again and slowly retracts to the 0 - position of the compression bin;

[0085] S4. When both the left compression piston 33 and the right compression piston 34 stop at the 0 - position of the compression bin, open the bin door 36. The push - out piston 35 slowly pushes out the square silage feed bale in the compression bin 32. At the same time, the longitudinal film - wrapping device 4 rotates to axially wrap the silage feed bale exposed outside the compression bin 32 with silage film. When the push - out piston 35 completely pushes out the silage feed bale from the compression bin 32, the axial film - wrapping of the silage feed bale is completed, and the silage feed bale falls above the horizontal film - wrapping device 5;

[0086] S5. After the silage feed bale falls above the horizontal film - wrapping device 5, the push - out piston 35 quickly retracts into the compression bin 32, and the bin door 36 closes. When the proximity switch detects that the push - out piston 35 retracts to the initial position, the left compression piston 33 and the right compression piston 34 start to quickly retract;

[0087] S6. After the silage bale falls above the horizontal film wrapping device 5, the weighing sensor below the horizontal film wrapping device 5 feeds back the weight of the silage bale. When the weighed weight is greater than the required value, when the left compression piston 33 and the right compression piston 34 retract, they will retract to the initial position near the 0 position of the compression chamber. At this time, the inlet of the compression chamber 32 decreases, the volume of the compression chamber 32 decreases, the silage entering the compression chamber 32 decreases, and the weight of the compressed and formed silage bale drops to the required value. When the weighed weight is less than the required value, the left compression piston 33 and the right compression piston 34 will retract to the initial position far from the 0 position of the compression chamber, the inlet of the compression chamber 32 increases, the volume of the compression chamber 32 increases, the silage entering the compression chamber 32 increases, and the weight of the compressed and formed silage bale rises to the required value. When the left compression piston 33 and the right compression piston 34 quickly retract to the set initial position, the feeding auger 38 starts to rotate, and the silage in the storage bin 37 falls into the compression chamber 32, reducing the feeding time.

[0088] S7. After the silage bale falls above the horizontal film wrapping device 5, the horizontal film wrapping device 5 rotates, and the silage bale rolls on the horizontal film wrapping device 5. The horizontal film wrapping device 5 wraps the two end faces of the silage bale with silage film to complete the all-round and non-dead-angle film wrapping. After the horizontal film wrapping is completed, the horizontal film wrapping device 5 flips to unload the silage bale with the film wrapped.

10. A wrapping method for a wrapping device with a full - range compression device for silage as claimed in any one of claims 5 - 9, characterized in that, It includes the following operating steps: S1. Start the motor (22) or the external power device, and the gearbox (23) drives the first hydraulic pump (25) and the second hydraulic pump (26) to start, providing power for the entire device; the feeding device (1) conveys the silage to the storage bin (37) through a conveyor belt, and the cloth auger (38) in the storage bin (37) rotates to spread the silage entering the storage bin (37) evenly and then drops it into the compression bin (32). S2. After the compression bin (32) is filled with silage, the cloth auger (38) stops rotating; at this time, the feeding device (1) continues to convey silage and temporarily stores and piles up the silage in the storage bin (37). S3. When loading the compression bin (32), the left compression piston (33) and the right compression piston (34) are both in the initial position. After the compression bin (32) is filled with silage, start the left compression piston (33) and the right compression piston (34) to simultaneously compress rapidly downward from the initial position; when the left compression piston (33) and the right compression piston (34) move to the 0 position of the compression bin, the left compression piston (33) stops compressing, the compression speed of the right compression piston (34) decreases, and continues to compress; when the right compression piston (34) reaches the set overpressure value, the right compression piston (34) decreases the speed again and slowly retracts to the 0 position of the compression bin. S4. When the left compression piston (33) and the right compression piston (34) both stop at the 0 position of the compression bin, open the bin door (36); the pushing piston (35) slowly pushes out the square silage bale in the compression bin (32), and at the same time the longitudinal film winding device (4) rotates to axially wind and wrap the silage bale exposed outside the compression bin (32) with a silage film; when the pushing piston (35) completely pushes out the silage bale from the compression bin (32), the axial film winding of the silage bale is completed, and the silage bale falls above the horizontal film winding device (5). S5. After the silage bale falls above the horizontal film winding device, the pushing piston (35) quickly retracts into the compression bin (32), and the bin door (36) closes; when the proximity switch detects that the pushing piston (35) retracts to the initial position, the left compression piston (33) and the right compression piston (34) start to quickly retract. S6. After the silage bale falls above the horizontal film wrapping device (5), the weighing sensor below the horizontal film wrapping device (5) feeds back the weight of the silage bale. When the weighed weight is greater than the required value, when the left compression piston (33) and the right compression piston (34) retract, they will retract to the initial position close to the 0 position of the compression bin. At this time, the inlet of the compression bin (32) decreases, the volume of the compression bin (32) decreases, the silage entering the compression bin (32) decreases, and the weight of the compressed and formed silage bale drops to the required value. When the weighed weight is less than the required value, the left compression piston (33) and the right compression piston (34) will retract to the initial position far from the 0 position of the compression bin, the inlet of the compression bin (32) increases, the volume of the compression bin (32) increases, the silage entering the compression bin (32) increases, and the weight of the compressed and formed silage bale rises to the required value. When the left compression piston (33) and the right compression piston (34) quickly retract to the set initial position, the cloth auger (38) starts to rotate, and the silage in the storage bin (37) falls into the compression bin (32), reducing the feeding time. S7. After the silage bale falls above the horizontal film wrapping device (5), the horizontal film wrapping device (5) rotates, and the silage bale rolls on the horizontal film wrapping device (5). The horizontal film wrapping device (5) wraps the two end faces of the silage bale with silage film, completing the all-round and non-dead-angle film wrapping. After the horizontal film wrapping is completed, the horizontal film wrapping device (5) flips to unload the silage bale with the film wrapping completed.
