Description

Technical Field

[0001] The invention relates to a pick-up, in particular to a periodic undulating curve conveyor belt type pick-up. Background Art

[0002] According to the crop characteristics of rapeseed, a "segmented harvesting method" of rapeseed is proposed, which includes harvesting, spreading, and drying rapeseed, and picking up and threshing rapeseed: first harvest the rapeseed, spread it out, and then dry it before picking it up and threshing it. This method utilizes the after-ripening effect of rapeseed itself and can effectively reduce the impact of its own characteristics on the harvest. It is another widely used harvesting method. The picking process is one of the key operating steps in segmented harvesting, and the operating effect of the picker is an important guarantee for the overall quality of segmented harvesting.

[0003] In the patent with publication number: CN207235493U, a two-stage pick-up device is disclosed, in which a conveyor belt or a pick-up toothed belt is tensioned between two driving rollers, and the rotation of the conveyor belt or the pick-up toothed belt is realized by friction. During the long-term operation of the device, the conveyor belt may slip due to insufficient tension; more seriously, due to the inconsistent friction between the two driving rollers, the conveyor belt and the pick-up toothed belt may easily deviate during the rotation process, affecting the transportation of rapeseed, and easily causing damage to the conveyor belt, delaying the harvesting process;

[0004] In summary, how to pick up and transport rapeseed, prevent the conveyor belt from slipping and deviation, and reduce the leakage of grains from the belt surface and reduce losses have become problems that researchers in this field urgently need to solve. Summary of the invention

[0005] The technical problem to be solved by the present invention is: how to realize the picking and transportation of rapeseed, prevent the conveyor belt from slipping and running off, and reduce the leakage of grains from the belt surface to reduce losses.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] The present invention discloses a periodic undulating curve conveyor belt pickup, comprising: two symmetrically arranged support seats; a first driving shaft, which is connected to the two support seats for rotation; a first driven shaft, which is arranged in parallel with the first driving shaft and is connected to the two support seats for rotation; a first sprocket, which is arranged at both ends of the first driving shaft and the first driven shaft; two first chains, which respectively cooperate with the first sprockets on the same side of the first driving shaft and the first driven shaft; a plurality of spaced-apart spring-tooth connecting plates, whose two ends respectively correspond to different chain links of the two first chains, and whose length direction is parallel to the first driving shaft; a flexible and wavy first conveyor belt, whose trough is connected to each of the spring-tooth connecting plates, and the first conveyor belt located between two adjacent spring-tooth connecting plates arches upward to form a wave crest; a plurality of spring teeth, which are arranged outside the first conveyor belt, and each of the spring teeth is connected to the spring-tooth connecting plate.

[0008] Compared with the traditional pickup that uses the rotating conveyor belt, the pickup in this solution uses a sprocket and chain combination to connect multiple spaced spring-tooth connecting plates with the chain links of the first chain, and the wavy first conveyor belt is connected to multiple spring-tooth connecting plates. The spring teeth are set on the first conveyor belt and fixedly connected to the spring-tooth connecting plates. The first conveyor belt between the two spring-tooth connecting plates forms a crest, and the two spring-tooth connecting plates are connected to the trough of the first conveyor belt. The first conveyor belt is made of PVC material and is molded into a wavy structure. The spacing between two adjacent troughs is equal to the spacing between the two spring-tooth connecting plates.

[0009] The first conveyor belt is designed to be a wave-shaped structure, and the grains will be placed at the trough during transportation to avoid rolling loss of the grains during transportation; in addition, due to the use of a spring-tooth connecting plate, a sprocket, and a chain, when the spring-tooth connecting plate moves to the arc at the end, a polygonal effect is formed. At this time, the first conveyor belt is tensioned and forms an arc-shaped surface. At this time, the peaks and troughs are smoothed, and the grains at the troughs will automatically fall and be transported out.

[0010] Furthermore, in the traditional picker, the spring teeth are fixed on the flexible conveyor belt, and the spring teeth are prone to deflection after being subjected to force. In this solution, the spring teeth are fixedly connected to the spring tooth connecting plate through fasteners, which ensures that the spring teeth are not deflected when subjected to force.

[0011] The cam is an angular channel that is arranged on the side of the second support frame and is provided with a plurality of channels, and the cam is connected to the plurality of channels by the plurality of channels respectively. The cam is connected to the plurality of channels by the plurality of channels respectively. The cam is connected to the plurality of channels by the plurality of channels.

[0012] In this solution, a wavy second conveyor belt is also used. The second conveyor belt has the same function as the first conveyor belt, which can prevent the second conveyor belt from deviating and avoid the loss of grains due to rolling during transportation.

[0013] In order to ensure the power transmission when the first driving shaft and the second driving shaft rotate, the end portions of the first driving shaft and the second driving shaft are connected through a third chain transmission;

[0014] In this solution, the output shaft of the motor is connected to the other end of the first driving shaft, and the power is transmitted between the first driving shaft and the second driving shaft through the third chain, so that the rotation speeds of the first driving shaft and the second driving shaft can be consistent.

[0015] In order to ensure that the first chain is tensioned between the first sprockets or the second chain is tensioned between the second sprockets, both ends of the first driven shaft and the second driven shaft are provided with sliding seats, and the sliding seats are linearly slidably fitted on the outer wall of the support seat; a fixed seat is fixed to the outer wall of the support seat, and a retractable tensioning rod is provided on the fixed seat, and the end of the tensioning rod is against the outer wall of the sliding seat;

[0016] The tensioning rod can be adjusted and retracted, for example, it can be extended or shortened by rotating it in a threaded manner, so that both ends of the tensioning rod are always against the fixed seat and the sliding seat. By controlling the position of the driven shaft, the chain is always tensioned between the two sprockets to avoid slippage between the chain and the sprocket.

[0017] Beneficial effects of the present invention: The present invention is a periodic undulating curve conveyor belt type pick-up. The pick-up in this scheme adopts the cooperation mode of sprocket and chain to connect a plurality of spring-tooth connecting plates arranged at intervals with the chain links of the first chain. The wavy first conveyor belt is connected with a plurality of spring-tooth connecting plates. The spring teeth are arranged on the first conveyor belt and fixedly connected with the spring-tooth connecting plates. The first conveyor belt between the two spring-tooth connecting plates forms a wave crest. Both spring-tooth connecting plates are connected with the wave trough of the first conveyor belt, thereby avoiding the first conveyor belt from slipping and running off during the rotation process.

[0018] In the process of conveying materials, the peaks and troughs formed by the periodic ups and downs of the conveyor belt can effectively reduce the leakage of grains from the conveyor belt and reduce losses; when the conveyor belt rotates back to the sprocket position, the peaks formed by the conveyor belt can reduce the pulling caused by the polygonal effect of the sprocket drive and extend the service life of the conveyor belt.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0024] like Figure 1-3 As shown, the present invention is a periodic undulating curve conveyor belt picker, comprising: two symmetrically arranged support seats 1; a first driving shaft 2, which is rotatably connected to the two support seats 1; a first driven shaft 3, which is arranged in parallel with the first driving shaft 2 and is rotatably connected to the two support seats 1; a first sprocket 4, which is arranged at both ends of the first driving shaft 2 and the first driven shaft 3; two first chains 5, which respectively cooperate with the first sprocket 4 on the same side of the first driving shaft 2 and the first driven shaft 3; a plurality of spaced-apart elastic tooth connecting plates 6, whose two ends respectively correspond to different chain links of the two first chains 5, and whose length direction is parallel to the first driving shaft 2; a flexible and wavy first conveyor belt 7, whose trough is connected to each of the elastic tooth connecting plates 6, and the first conveyor belt 7 located between two adjacent elastic tooth connecting plates 6 is arched upward to form a wave crest; a plurality of elastic teeth 8, which are arranged outside the first conveyor belt 7, and each of the elastic teeth 8 is connected to the elastic tooth connecting plate 7.

[0025] Compared with the traditional pickup that adopts the rotating method of the conveyor belt, the pickup in this scheme adopts the matching method of sprocket and chain to connect multiple spaced spring tooth connecting plates 6 with the chain links of the first chain 4, and the wavy first conveyor belt 7 is connected with multiple spring tooth connecting plates 6. The spring teeth 7 are arranged on the first conveyor belt 7 and fixedly connected with the spring tooth connecting plates 6. The first conveyor belt 7 between the two spring tooth connecting plates 6 forms a crest, and the two spring tooth connecting plates 6 are connected to the trough of the first conveyor belt 7; the first conveyor belt 7 is made of PVC material and is molded into a wavy structure, and the distance between two adjacent troughs is equal to the distance between the two spring tooth connecting plates 6.

[0026] The first conveyor belt 7 is designed to be a wave-shaped structure, and the grains will be placed at the trough during transportation to avoid rolling loss of the grains during transportation; in addition, due to the use of a spring-tooth connecting plate 6, a sprocket, and a chain, when the spring-tooth connecting plate moves to the arc at the end, a polygonal effect will be formed. At this time, the first conveyor belt 7 is tensioned and forms an arc-shaped surface. At this time, the peaks and troughs are smoothed, and the grains at the troughs will automatically fall and be transported out.

[0027] The polygonal effect is that the chain is made up of many chain links connected by pins. When the chain is wrapped around the sprocket, the meshing points between the chain and the sprocket are distributed along the circumference of the sprocket, so that the chain forms an approximate polygonal shape during movement. At this time, due to the existence of wave peaks on the corresponding conveyor belt, the corresponding conveyor belt has an extension margin when passing the meshing point, which can avoid pulling damage.

[0028] Furthermore, in the traditional picker, the spring tooth 8 is fixed on the flexible conveyor belt, and the spring tooth 8 is easy to deflect after being subjected to force. In this solution, the spring tooth 8 is fixedly connected to the spring tooth connecting plate 6 by a fastener, which ensures that the spring tooth 8 does not deflect when subjected to force.

[0029] In order to prevent the conveyor belt in the background technology from being offset during operation, the present solution also includes: a second driving shaft 9, which is connected to the two support seats 1 for rotation; a second driven shaft 10, which is arranged in parallel with the second driving shaft 9 and is connected to the two support seats 1 for rotation; a second sprocket 11, which is arranged at both ends of the second driving shaft 9 and the second driven shaft 10; two second chains 12, which respectively cooperate with the second sprocket 11 on the same side of the second driving shaft 9 and the second driven shaft 10; a conveyor belt connecting plate 13, whose two ends correspond to different chain links of the two second chains 12, and whose length direction is parallel to the second driving shaft 9; a flexible and wavy second conveyor belt 134, whose trough is connected to each of the conveyor belt connecting plates 13, and the second conveyor belt 14 located between the two adjacent conveyor belt connecting plates 13 is arched upward to form a wave crest; wherein, the first conveyor belt 7 is arranged obliquely upward, and the second conveyor belt 14 is also arranged obliquely, and one end of the first conveyor belt 7 is located below one end of the second conveyor belt 14;

[0030] In this solution, a wavy second conveyor belt 14 is also used. The second conveyor belt 14 has the same function as the first conveyor belt 7, which can prevent the second conveyor belt 14 from deviating and avoid the rolling loss of grains during transportation.

[0031] In order to ensure the power transmission when the first driving shaft 2 and the second driving shaft 9 rotate, the end portions of the first driving shaft 2 and the second driving shaft 9 are connected by a third chain 15;

[0032] In this solution, the output shaft of the motor is connected to the other end of the first driving shaft 2, and the power is transmitted between the first driving shaft 2 and the second driving shaft 9 through the third chain 15, so that the rotation speeds of the first driving shaft 2 and the second driving shaft 9 can be kept consistent.

[0033] In order to ensure that the first chain is tensioned between the first sprockets or the second chain is tensioned between the second sprockets, both ends of the first driven shaft 3 and the second driven shaft 10 are provided with sliding seats 16, and the sliding seats 16 are linearly slidably fitted on the outer wall of the support seat 1; the outer wall of the support seat 1 is fixed with a fixed seat 17, and a retractable tensioning rod 18 is provided on the fixed seat 17, and the end of the tensioning rod 18 is against the outer wall of the sliding seat 16;

[0034] The tensioning rod 18 can be adjusted and retracted, for example, it can be extended or shortened by rotating it in a threaded manner, so that both ends of the tensioning rod 18 are always against the fixed seat 17 and the sliding seat 16. By controlling the position of the first or second driven shaft, the corresponding chain is always tensioned between the two sprockets to avoid slippage between the chain and the sprocket.
