Description

Technical Field

[0001] The invention relates to the field of resource recycling, in particular to a combined continuous feeding device for recycling bales of straw. Background Art

[0002] This solution aims to solve the problems of poor applicability, large volume, high power consumption, and easy accumulation of straw in the feeding method and device for recycling straw resources.

[0003] The silkening of straw is the foundation of various technologies for the recycling of crop straw resources, and the silkening effect directly affects the comprehensive utilization of resources. Baled straw is usually large in size and regular in shape. Currently, there are many types of equipment for continuous feeding devices for bales. In terms of process flow, the feeding methods for bales are roughly divided into manual, vertical, drum, and conveyor belt types. These four feeding methods have their own advantages and disadvantages and cannot achieve a continuous conveying process. There are problems such as reduced productivity, increased labor intensity, poor material movement, and material accumulation at the discharge port, which cannot achieve continuous feeding of bales of straw. Therefore, by innovatively improving the existing feeding methods, a feeding device with low power consumption, compact structure, and low manufacturing cost is designed, which is more stable than previous devices, has a high degree of automation, low personnel occupancy rate, and better continuous conveying effect.

[0004] Existing feeding equipment usually consists of a drive device, a conveying mechanism and a control unit. Its working principle is based on motor drive. By adjusting the speed and structural parameters of the conveying mechanism, such as the auger, chain plate, roller, etc., continuous and uniform feeding of materials is achieved.

[0005] (1) Manual

[0006] Manual feeding is the most common method, where the operator stands at the feed port and feeds the bales by hand or with tools. This method offers the advantages of low power consumption, reduced jamming, and the operator's ability to adjust the feed rate based on the machine's current status. However, due to its reliance on manual labor, it cannot achieve automated, continuous feeding, resulting in low efficiency and high labor intensity.

[0007] (2) Vertical

[0008] The vertical feeding method has the feed port located directly above the equipment, with the silkening unit directly below. The feed port is typically open and upward-facing, forming a vertical structure. The operator places the bale into the open feed port, where it is then carried by gravity to the straw processing machinery for processing. This method is characterized by low power consumption, but the uncontrolled gravity makes it difficult to adjust the feed rate, which can easily lead to material entanglement and jamming. Furthermore, the feed port is located high above the equipment, making feeding difficult for the operator.

[0009] (3) Drum type

[0010] Lin Dejin from Taiwan invented a straw conveyor that adds a roller above the conveyor belt. The roller has hooks on the surface, which rotate in the opposite direction of the conveyor belt below. The two conveyors are synchronized to achieve the purpose of feeding. Although it solves the problems of uneven feeding and blockage, it has limited adaptability to the size and shape of the straw bales, and may require additional adjustments and adaptations.

[0011] (4) Conveyor belt type

[0012] Conveyor belt conveying equipment is the most common method today. Through motor or tractor power transmission, the bales are fed in the direction of the conveyor belt rotation. Compared with manual input, this method greatly reduces the operator's workload. The disadvantages are that the conveyor belt occupies a large area, is inconvenient to move, has high manufacturing costs, and high power consumption. In straw processing machinery, there is a phenomenon of material leakage at the process handover between the conveyor belt and the next process. The conveyor belt conveying method is not suitable for the unpacking of bales. Due to the large size of the bales, it is necessary to adjust to better parameters to ensure that the bales of straw materials are not stuck at the feed port. Summary of the Invention

[0013] In order to solve the above problems, the present invention proposes a combined continuous feeding device for the recycling of straw bales, which can realize material transportation and feeding and achieve continuous feeding of straw bales.

[0014] To achieve the above object, the technical solution adopted by the present invention is:

[0015] A combined continuous feeding device for recycling straw bales, comprising:

[0016] The counterweight mechanism includes a counterweight vehicle track, a counterweight vehicle, and a counterweight vehicle roller. The counterweight vehicle track is located on the side baffles on both sides of the continuous conveying platform. The counterweight vehicle is installed on the counterweight vehicle track.

[0017] Continuous conveying mechanism, including a conveying platform frame, a platform angle lift and a continuous conveying platform;

[0018] The fork mechanism includes a power mechanism, a transmission mechanism, a material receiving plate and a shift fork. The power mechanism is connected to the shift fork through the transmission mechanism. The position of the shift fork is opposite to the groove. The power mechanism drives the shift fork to move through the transmission mechanism. The shift fork mechanism can drive the shift fork to enter the groove from under the material receiving plate in the forward stroke and shift the bale of straw to move away from the continuous conveying platform. The shift fork mechanism can drive the shift fork to exit the material receiving plate and reset in the reverse stroke. A material receiving plate is installed above the fork mechanism and is aligned with the conveying end of the above-mentioned continuous conveying platform. A hollow groove is provided on the material receiving plate.

[0019] Preferably, the power mechanism is a pulley;

[0020] The transmission mechanism includes a crank, a connecting rod and a rocker, wherein the first end of the crank is connected to the pulley and can drive the crank to rotate around the axis of the pulley, the first end of the connecting rod is hinged to the second end of the crank, the second end of the crank is hinged to the first end of the rocker, the second end of the rocker is hinged to the shaft, and the shift fork is connected to the second end of the connecting rod.

[0021] Preferably, a toothed roller is provided above the fork mechanism, the toothed roller is located on the receiving plate of the fork mechanism and behind the fork in the direction of straw baling transmission, the toothed roller comprises a roller body and several groups of rolling teeth installed outside the roller body.

[0022] Preferably, the fork mechanism further includes a transmission belt, which is transmission-connected to the pulley and the toothed roller shaft.

[0023] Preferably, the travel of the end of the shift fork above the carrier plate is a part of an ellipse.

[0024] Preferably, when the end of the shift fork enters the material receiving plate, the moving direction of the end of the shift fork is perpendicular to the material receiving plate.

[0025] Preferably, the continuous conveying platform is an inclined platform with a front end higher than a rear end.

[0026] Preferably, the continuous conveying platform is provided with side baffles on both sides of the conveying direction, and the continuous conveying platform also includes a counterweight vehicle track arranged along the conveying direction of the continuous conveying platform, and a counterweight vehicle is installed on the track. The counterweight vehicle is used to slide along the track by its own weight to push the bales of straw to move on the continuous conveying platform.

[0027] Preferably, the counterweight vehicle track is a guide structure of the upper bending stroke of the side baffle.

[0028] Preferably, the platform angle lifting mechanism further includes a platform angle lifting mechanism for adjusting the inclination angle of the continuous conveying platform.

[0029] The beneficial effects of using the present invention are:

[0030] Therefore, the continuous conveying device in this solution is an innovative improvement on the existing feeding method. This solution realizes the continuous feeding of bales of straw through the push-push-delivery coordinated work of the counterweight vehicle, the fork mechanism and the toothed roller shaft.

[0031] This device overcomes the friction between the bales and the surface of the buffer platform by the thrust of the counterweight vehicle on the straw bales and the gravity of the bales themselves, and slides on the surface of the buffer platform. It can transport 4 to 10 bales of material at a time, effectively solving the problem of difficulty in loading materials for operators. At the same time, it can also lower the center of gravity of the continuous conveying platform to prevent the platform from tipping over due to excessively high angles.

Secondly, the shift fork mechanism and toothed roller shaft in this solution realize the function of continuous feeding of straw bales. The principle of the shift fork mechanism is a crank rocker structure. The quick return characteristics of the crank rocker structure can realize the conversion of various motion forms. The crank is connected by a connecting rod so that the rocker does not need to rotate a full circle. The average speed of the working stroke of the rocker is low, the working stroke is stable, and the speed of the non-working stroke is accelerated, so as to shorten the non-working time and achieve the purpose of improving work efficiency. By rotating the crank, the fork tooth tip makes reciprocating motion on the material receiving plate, and the toothed roller shaft cooperates with the fork mechanism to transport the material. At the same time, the anti-blocking design can also block the material moving down from the buffer platform, preventing the bales from entering the subsequent process at one time and causing machine blockage.

[0045] In order to make the purpose, technical solution and advantages of this technical solution more clear, the following technical solution is further described in detail in conjunction with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of this technical solution.

[0046] In order to solve the many disadvantages of manual feeding and mechanical feeding in the existing technology, such as Figure 1 As shown, this embodiment proposes a combined continuous feeding device for recycling baled straw, which includes a front sliding feeding structure. Specifically, the front sliding feeding structure includes a frame 1, which is a metal welded bracket structure. 2-4 fixed pulleys 11 are provided on one side of the bottom of the frame 1, and 2 universal pulleys 12 are provided on the other side to facilitate the steering movement of the platform when it moves.

[0047] A platform angle lift mechanism 2 is provided at the front of the frame 1. In this embodiment, the platform angle lift mechanism 2 comprises a guide block, a lift rod, and a control device. The lift rod is inserted into a through-hole in the guide block, and the control device is used to control the lift rod to slide within the guide block to adjust the height of the top of the lift rod. In some feasible embodiments, the lift rod and the control device may utilize a worm gear transmission structure with a self-locking function to control the height position of the lift rod.

[0048] A continuous conveying platform 3 is mounted on the frame 1. The front end of the continuous conveying platform 3 is hinged to the lifting end of the platform angle lifting mechanism 2, and the rear end of the continuous conveying platform 3 is hinged to the frame 1. The inclination angle of the conveying surface at the top of the continuous conveying platform 3 can be controlled by the continuous conveying platform 3. A side baffle 4 is mounted on each of the left and right sides of the conveying plane of the continuous conveying platform 3. The top of the side baffle 4 is a counterweight vehicle track 41. In other embodiments, a separately assembled counterweight vehicle track 41 for guiding the counterweight vehicle 5 can be used. In this embodiment, the counterweight vehicle track 41 is a guide structure for the upper bending stroke of the side baffle 4. Such a guide structure is simple in structure, reduces costs, and does not require a separate guide structure.

[0049] A counterweight vehicle 5 is provided on the continuous conveying platform 3 and the side baffle brackets on both sides. Figure 2 and Figure 8As shown in the figure, the counterweight cart 5 is located at the starting end of the feed of the continuous conveying platform 3, and the counterweight cart track 41 is above the top of the baffle 4 on both sides of the continuous conveying platform 3 and is parallel to it. The specific size of the counterweight cart 5 is determined according to the external dimensions of the bales of straw. Its overall center of gravity is located in the middle and front, which increases the pushing force of the counterweight cart 5 on the inclined surface. Two limit devices are welded at the end of the counterweight cart track 41. When the counterweight cart roller 51 contacts the limit device, the counterweight cart 5 stops sliding down. The main function of the counterweight cart 5 is to push the square straw material on the buffer platform by its own gravity. The platform angle can be lowered by the push of the counterweight cart 5 to prevent the operator from having difficulty loading the material due to the high angle of the buffer conveying platform. At the same time, the center of gravity of the buffer conveying platform can also be lowered to prevent the platform from tipping over due to the high angle. The counterweight cart 5 is equipped with 4 rollers on both sides, and the rollers roll in the track welded with angle steel. The counterweight vehicle 5 is equipped with a hook at the rear for hanging on the frame 1 of the buffer platform. When the square bales of straw material are loaded on the buffer platform, the hook is released and the counterweight vehicle 5 moves under the action of its own weight.

[0050] A tail frame 8 is provided at the conveying end of the continuous conveying platform 3 , and the tail frame 8 is used to install a material receiving plate 81 and a toothed roller shaft 6 . A shift fork mechanism 7 is provided below the outer frame.

[0051] like Figure 3 As shown, the fork mechanism 7 includes a power mechanism, a transmission mechanism, and a fork 75. The power mechanism is connected to the fork 75 via the transmission mechanism. The fork 75 is positioned opposite the groove on the receiving plate 81. The power mechanism drives the fork 75 through the transmission mechanism. During the forward stroke, the fork mechanism 7 drives the fork 75 from below the receiving plate 81 into the groove and shifts the bale of straw away from the continuous conveying platform 3. During the reverse stroke, the fork mechanism 7 drives the fork 75 out of the receiving plate 81 and into its original position.

[0052] In this embodiment, the power mechanism of the fork mechanism 7 is a pulley 71, and the transmission mechanism includes a crank 72, a connecting rod 73 and a rocker 74, wherein the first end of the crank 72 is connected to the pulley 71 and can drive the crank 72 to rotate around the axis of the pulley 71, the first end of the connecting rod 73 is hinged to the second end of the crank 72, the second end of the crank 72 is hinged to the first end of the rocker 74, the second end of the rocker 74 is hinged to the shaft, and the fork 75 is connected to the second end of the connecting rod 73.

[0053] A toothed roller 6 is also provided above the receiving plate 81 of the fork mechanism 71. The toothed roller 6 is located on the receiving plate 81 and behind the fork 75 in the direction of straw bale transmission. The toothed roller 6 includes a roller body 61 and several groups of rolling teeth 62 installed outside the roller body 61.

[0054] Combine Figure 4As shown, specifically, a hole is provided on the front of the connecting rod 73 for connecting the shift fork 75, which is docked with the shift fork mounting hole 751 on the shift fork 75. During operation, the rocker 74 cannot rotate the full range. The crank 72 is connected to the bottom hole of the connecting rod 73 by a bolt connection. The crank 72 shaft, the rotating roller shaft and the output shaft of the motor are connected by a pulley 71 and a transmission belt. The rotation of the crank 72 shaft drives the connecting rod 73 and the shift fork 75 to move, so that the tooth tip of the shift fork 75 reciprocates on the receiving plate 81. A toothed roller shaft 6 is provided above the receiving plate 81. The rotational power comes from the crank shaft pulley 71 in the shift fork mechanism 7 and is transmitted through the transmission belt 76. The rotation direction of the toothed roller shaft 6 is clockwise. The function of the toothed roller shaft 6 is to cooperate with the fork mechanism 7 to transport square bales of straw materials. At the same time, it is also used to block the square bales of straw materials at the rear to prevent the fork mechanism 7 from driving the entire square bale of straw materials into the subsequent straw square bale processing device. The large volume of square bales of straw causes blockage of the bale breaking mechanism.

[0055] like Figure 5 and Figure 7 As shown, when the fork mechanism 7 is working, the crank 72 rotates, driving the connecting rod 73 and the rocker 74 to do reciprocating motion, and the fork 75 is fixed on the connecting rod 73. Above the fork mechanism 7 is a receiving plate 81, which has grooves with the same spacing. The fork 75 tooth tips move in conjunction with the fork 75 tooth tips. The fork 75 tooth tips extend to the upper surface of the receiving plate 81, thereby driving the square straw bale material to move toward the rotating roller axis. When the fork 75 tooth tip reaches the left end of the receiving plate 81, it exits from under the receiving plate 81 and moves to the right to return to the initial position, and repeats the cycle. Figure 5 As shown, when the pulley 71 rotates clockwise, the fork mechanism 7 moves from the first position 7A to the second position 7B, and the travel of the tip of the end of the fork 75 is shown as the travel C.

[0056] In a four-bar linkage such as the shift fork mechanism 7, when the crank 72, the active component, rotates at a constant speed, the reciprocating stroke and reciprocating speed of the driven rocker 74 differ, with the return stroke being faster than the forward stroke. This motion characteristic is known as the quick return characteristic. The average speed of the shift fork 75 tooth tip above the material receiving plate 81 is low, ensuring stable material feeding by the shift fork mechanism 7. The return stroke speed of the shift fork 75 tooth tip below the material receiving plate 81 is accelerated, shortening the return time and improving the operating efficiency of the shift fork mechanism 7.

[0057] like Figure 6 As shown, the toothed roller 6 includes a roller body 61, a plurality of sets of hobbing teeth 62 are provided on the outer periphery of the roller body 61, bearing bushes 63 are provided at both ends of the roller body 61, and the ends of the roller body 61 extend to roller ends 64. The toothed roller 6 is assembled in a groove on the tail frame 8.

[0058] The device disclosed in this invention consists of a counterweight vehicle 54, a continuous conveying platform 3 angle lifting mechanism 26, a continuous conveying platform frame 1, a sliding steel plate for the continuous conveying platform 3, a shift fork 75 with a toothed roller shaft 6, and a shift fork mechanism 7. The continuous conveying platform 3 operates at a 10° to 25° angle with the ground. The combined force of the bales' own weight and the thrust of the counterweight vehicle 5 behind them overcomes the friction between the bales and the surface of the continuous conveying platform 3, allowing them to slide on the surface of the continuous conveying platform 3, thus achieving automatic and continuous conveying of the bales. To accommodate 4 to 10 bales simultaneously, the continuous conveying platform 3 is designed to have a width of 1500 to 2500 mm. The continuous conveying platform 3 frame 1 is welded from 40 / 50 / 60 square steel pipes, and the frame 1 reinforcement is welded from 40 / 50 / 60 angle steel.

[0059] The continuous conveying platform 3 is at a certain angle to the ground. The thrust of the counterweight vehicle 5 on the straw bales and the gravity of the bales themselves overcome the friction between the bales and the surface of the buffer platform, and the bales slide on the surface of the buffer platform. 4 to 10 bales of material can be conveyed at a time, effectively solving the problem of difficulty in loading materials for operators. At the same time, the center of gravity of the continuous conveying platform 3 can also be lowered to prevent the platform from tipping over due to excessively high angles. This design improves the stability and safety of the feeding process. Secondly, the shift fork mechanism 7 and the toothed roller shaft 6 in this solution realize the function of continuous feeding of straw bales. The principle of the shift fork mechanism 7 is a crank-rocker structure. By utilizing the quick return characteristics of the crank-rocker structure, it is possible to realize the conversion of various motion forms. The crank 72, through the connecting rod 73, makes it unnecessary for the rocker 74 to rotate a full circle. The average speed of the working stroke of the rocker 74 is low, the working stroke is stable, and the speed of the non-working stroke is accelerated, so as to shorten the non-working time and achieve the purpose of improving work efficiency. By rotating the crank 72, the tooth tip of the fork 75 makes reciprocating motion on the receiving plate 81, and the toothed rotating roller cooperates with the fork mechanism 7 to transport the material. At the same time, the anti-blocking design can also block the material moving down from the buffer platform, preventing the bales from entering the subsequent process at one time and causing machine blockage, which is not available in traditional feeding devices.

[0060] When the straw bale is on the continuous conveying platform 3, the bale is subjected to the "pushing" force of the counterweight vehicle 5. Under the action of its own gravity, the counterweight vehicle 5 pushes the straw bale to the position of the material receiving plate 81 on the track, and the crank 72 of the fork mechanism 7 rotates under the drive of the motor. Under the joint action of the crank 72 and the rocker 74, the connecting rod 73 causes the tooth tip of the fork 75 to reciprocate to "shift" the straw bale. The crank 72 shaft drives the rotating roller shaft to rotate through the transmission belt. The clockwise rotation of the rotating roller shaft and the reciprocating counterclockwise rotation of the fork 75 cooperate to "deliver" the straw square bale into the rear straw processing device.

[0061] The method of using this device is as follows:

[0062] According to the on-site terrain, the angle of the continuous conveying platform 3 is adjusted with the continuous conveying platform 3 elevator, and the bales are placed on the continuous conveying platform 3; the power of the equipment is started, the speed of the equipment is adjusted according to the moisture content of the straw, and the equipment is kept idling for a period of time. After the equipment is running stably, the counterweight vehicle 5 is released and the straw bales are fed; the bale material overcomes the friction between the bale material and the surface of the buffer platform on the inclined surface of the buffer platform through the combined force of its own gravity and the thrust of the rear counterweight vehicle 5, and slides on the surface of the buffer platform and moves to the fork mechanism 7; the fork 75 and the The rotating toothed rollers 6 cooperate with each other, and the crank 72 rotates clockwise. Under the linkage of the crank rocker mechanism, the shift fork 75 makes a reciprocating motion, so that the tooth tip of the shift fork 75 drives the bale to move to the left, tearing the bale material apart; at the same time, in order to prevent the problem of material blockage, the toothed roller 6 can block the bale material at the rear to prevent the material from entering the subsequent bale processing device at one time; under the push-push-delivery combination action, the fed straw is transferred to the subsequent crushing or kneading mechanism, realizing the mechanical operation process of automatic, continuous and smooth feeding of the bale straw.

[0063] It should be noted that, in the description of the present invention, unless otherwise specified, the meaning of "multiple" is two or more; the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. At the same time, in the description of the present invention, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0064] The above content is only a preferred embodiment of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scope based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
