Description

Technical Field

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

[0002] The present invention aims to solve the problems of poor applicability, large volume, high power consumption, and easy accumulation of materials in feeding methods and devices for straw bales when recycling straw resources.

[0003] The silkening of straw is the basic work 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. At present, 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 situations 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 innovating and improving the existing feeding method, a feeding device with low power consumption, compact structure and low manufacturing cost is designed, so that it can achieve the purpose of being more stable than previous devices, with 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 can be achieved.

[0005] (1) Manual

[0006] Manual feeding is the most common feeding method, where the operator stands at the feeding port and feeds the bales in with his hands or tools. The advantages of this method are that the straw processing machinery requires low power consumption, is not prone to jamming, and the operator can adjust the feed amount according to the current state of the machine. However, due to its reliance on manpower, it is impossible to achieve automatic continuous feeding, which is inefficient and labor-intensive.

[0007] (2) Vertical

[0008] The feed port of the vertical feeding method is located directly above the equipment, and the silkening device is directly below it. The feed port structure is generally an upward open, vertical device. The operator puts the bale into the open feed port, and the bale is sent to the straw processing machinery by its own gravity for work. The characteristics of this method are that the equipment requires low power consumption, but the gravity cannot be controlled, resulting in the inability to adjust the feed amount, which is prone to material entanglement and jamming. In addition, the feed port is located at a high position directly above the equipment, which makes it difficult for the operator to feed the material.

[0009] (3) Drum type

[0010] Lin Dejin invented a straw conveyor, which adds a roller above the conveyor belt. The roller surface has hooks, which rotate in the opposite direction of the conveyor belt below. The two convey the material synchronously. 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 nowadays. Through the power transmission of motors or tractors, the bales follow the direction of rotation of the conveyor belt for material supply. This method is relatively manual input and 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 junction of the conveyor belt and the next process. The conveyor belt conveying method is not suitable for the unpacking of bales. Because the size of the bales is too large, it needs to be adjusted to better parameters to ensure that the bale straw material will not be stuck at the feeding port. Summary of the invention

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

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

[0017] A continuous conveying mechanism, comprising 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 fork. The power mechanism is connected to the fork through the transmission mechanism. The positions of the fork and the groove are opposite. The power mechanism drives the fork to move through the transmission mechanism. The fork mechanism can drive the fork to enter the groove from under the material receiving plate in a forward stroke and move the bale of straw away from the continuous conveying platform. The fork mechanism can drive the fork to exit the material receiving plate and reset in a 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 arranged 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 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 transmission direction of the straw bale, and the toothed roller comprises a roller body and several groups of rolling teeth installed outside the roller body.

[0022] Preferably, the fork mechanism further comprises a transmission belt, and the transmission belt is drivingly 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 also 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 scheme is innovatively improved on the existing feeding method. This scheme realizes the continuous feeding of the bale straw through the push-push-delivery cooperation 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 through 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 feeding 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. This design improves the stability and safety of the feeding process. Secondly, the fork mechanism and the toothed roller shaft in this scheme realize the function of continuous feeding of straw bales. The principle of the 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 through 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 small, the working stroke is stable, and the non-working stroke speed is accelerated, so as to shorten the non-working time and achieve the purpose of improving work efficiency. By rotating the crank, the fork teeth make reciprocating motion on the receiving plate, and the toothed roller 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 to prevent 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 the technical solution more clear, the technical solution is further described in detail below 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 the 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 straw bales, 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 arranged on one side of the bottom of the frame 1, and 2 universal pulleys 12 are arranged on the other side to facilitate the steering movement of the platform when it moves.

[0047] The front part of the frame 1 is provided with a platform angle lifting mechanism 2. In this embodiment, the platform angle lifting mechanism 2 includes a guide block, a lifting support rod and a control device, wherein the lifting support rod is inserted into the through hole of the guide block, and the lifting support rod can be controlled by the control device to slide in the guide block to adjust the height of the top of the lifting support rod. In some feasible embodiments, the lifting support rod and the control device can use a worm gear transmission structure, which has a self-locking function to control the height position of the lifting support rod.

[0048] A continuous conveying platform 3 is installed 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. The rear end of the continuous conveying platform 3 is hinged to the frame 1. The inclination angle of the top conveying surface of the continuous conveying platform 3 can be controlled by the continuous conveying platform 3. A side baffle 4 is installed 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 counterweight vehicle track 41 assembled separately for guiding the counterweight vehicle 5 can be used. In this embodiment, the counterweight vehicle track 41 is a guide structure for the upper edge 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 counterweight vehicle 5 is located at the starting end of the feeding of the continuous conveying platform 3, and the counterweight vehicle 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 vehicle 5 is determined according to the external dimensions of the bale of straw. Its overall center of gravity is located in the middle and front, which increases the driving force of the counterweight vehicle 5 on the inclined plane. Two limit devices are welded at the terminal of the counterweight vehicle track 41. When the roller 51 of the counterweight vehicle contacts the limit device, the counterweight vehicle 5 stops sliding down. The main function of the counterweight vehicle 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 vehicle 5 to prevent the operator from having difficulty in loading materials due to the excessively 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 excessively high angle. The counterweight vehicle 5 is equipped with 4 rollers on both sides, and the rollers roll in the track welded with angle steel. A hook is mounted at the rear of the counterweight vehicle 5 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 through the transmission mechanism. The fork 75 is opposite to the groove on the receiving plate 81. The power mechanism drives the fork 75 to move through the transmission mechanism. The fork mechanism 7 can drive the fork 75 to enter the groove from below the receiving plate 81 in the forward stroke and move the bale of straw away from the continuous conveying platform 3. The fork mechanism 7 can drive the fork 75 to exit the receiving plate 81 and reset in the reverse stroke.

[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 a plurality of groups of rolling teeth 62 installed outside the roller body 61 .

[0054] Combination Figure 4As shown, specifically, a hole is provided on the front of the connecting rod 73 for connecting the shift fork 75, which is connected to the shift fork mounting hole 751 on the shift fork 75, and the rocker 74 cannot rotate the full range during operation. The crank 72 is connected to the bottom hole of the connecting rod 73 by 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, which 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 the square bale of straw material. At the same time, it is also used to block the square bale of straw material at the rear to prevent the fork mechanism 7 from driving the entire square bale of straw material into the subsequent straw square bale processing device. The large volume of the square bale of straw causes the bale breaking mechanism to get stuck.

[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, on which grooves with the same spacing are provided, which cooperate with the movement of the fork 75 tooth tip, and the fork 75 tooth tip extends to the upper surface of the receiving plate 81, thereby driving the square bale of straw material to move in the direction of the rotating roller shaft. When the fork 75 tooth tip reaches the left end of the receiving plate 81, it exits from under the receiving plate 81, moves to the right and returns 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 at the end of the fork 75 is shown as travel C.

[0056] In a four-bar linkage such as the fork mechanism 7, when the crank 72 rotates at a constant speed as the active component, the reciprocating swing stroke and reciprocating speed of the driven rocker 74 are different, and the return stroke is faster than the forward stroke. This motion characteristic is called a quick return characteristic. The average stroke speed of the fork 75 tooth tip above the receiving plate 81 is small, so that the fork mechanism 7 is stable when feeding materials. The return stroke speed of the fork 75 tooth tip below the receiving plate 81 is accelerated to shorten the return time and improve the working efficiency of the fork mechanism 7.

[0057] like Figure 6 As shown, the toothed roller 6 comprises a roller body 61, a plurality of groups of rolling teeth 62 are arranged on the outer periphery of the roller body 61, bearing bushes 63 are arranged 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 the present invention is composed of a counterweight vehicle 54, a continuous conveying platform 3 angle lifting mechanism 26, a continuous conveying platform frame 1, a continuous conveying platform 3 sliding steel plate, a shift fork 75 with a toothed roller shaft 6, a shift fork mechanism 7, etc. The principle of the continuous conveying platform 3 is that due to the certain angle of 10° to 25° between the platform and the ground, the bale material on the inclined surface of the continuous conveying platform 3 overcomes the friction between the bale material and the surface of the continuous conveying platform 3 through the combined force of its own gravity and the thrust of the counterweight vehicle 5 behind, and slides on the surface of the continuous conveying platform 3 to realize the function of automatic continuous conveying of the bale material. In order to achieve the simultaneous buffering of 4 to 10 bales of bale material, the continuous conveying platform 3 is designed to be 1500 to 2500 mm. The frame 1 of the continuous conveying platform 3 is welded from 40 / 50 / 60 square steel pipes, and the reinforcement material of the frame 1 is selected from 40 / 50 / 60 angle steel for welding.

[0059] There is a certain angle between the continuous conveying platform 3 and the ground. The thrust of the counterweight vehicle 5 on the straw bale and the gravity of the bale itself overcome the friction between the bale material and the surface of the buffer platform, and slide on the surface of the buffer platform. 4 to 10 bales of material can be conveyed at a time, which effectively solves the problem of difficulty in feeding for operators. At the same time, the center of gravity of the continuous conveying platform 3 can 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 fork mechanism 7 and the toothed roller shaft 6 in this scheme realize the function of continuous feeding of straw bales. The principle of the fork mechanism 7 is a crank rocker structure. The quick return characteristics of the crank rocker structure can realize the conversion of various motion forms. The crank 72 makes the rocker 74 not need to rotate a full circle through the connecting rod 73. The average speed of the working stroke of the rocker 74 is small, the working stroke is stable, and the non-working stroke speed 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 to prevent 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 on the track to the position of the receiving plate 81, 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 makes the tooth tip of the fork 75 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: 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, and the equipment speed 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 through the combined force of its own gravity and the thrust of the rear counterweight vehicle 5 on the inclined surface of the buffer platform, and slides on the surface of the buffer platform and moves to the fork mechanism 7; the fork 75 and the fork mechanism 7 are connected. The rotating toothed roller shafts 6 cooperate with each other, and the crank 72 rotates clockwise. Under the linkage of the crank rocker mechanism, the shift fork 75 reciprocates, 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 shaft 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 combined action of pushing-pull-sending, 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 orientation or position relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does 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 a limitation of the present invention. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes 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 directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes 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.
