Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a forage picking structure and a baler. Background Art

[0002] The grass picking structure generally picks up the grass from the ground by the rotation of the picking roller and relies on the spring teeth installed on the picking roller, and feeds the grass into a forming chamber into bundles with the help of the rotation of the spring teeth. However, due to the effect of centrifugal force, the grass will fall forward after being picked up by the spring teeth, thereby affecting the grass picking efficiency. In the related art, in order to prevent the grass from falling forward, a round roller type grass pressing device is often provided in front of the picking roller, so that the grass that falls forward is blocked by the round roller in the grass pressing device and continues to be fed into the forming chamber at the rear with the help of the spring teeth.

[0003] However, the friction between the round rollers in the above-mentioned grass pressing device and the forward-moving grass will increase the resistance of the grass flow, causing the grass to slow down or even choke, thus affecting the efficiency of the whole machine. Utility Model Content

[0004] The utility model provides a forage grass picking structure and a baler, so as to solve the technical problem that the existing grass picking device is prone to slowing down the grass or even choking the grass when picking up the grass.

[0005] The utility model discloses a forage picking structure, comprising: a picking assembly, the picking assembly comprising a bracket, a picking roller rotatably connected to the bracket, and rows of spring teeth uniformly distributed on the picking roller along the circumferential direction; a grass pressing assembly, arranged at the upper front of the spring teeth in the grass picking direction, comprising a connecting frame, at least three conveying rollers rotatably arranged on the connecting frame, and an elastic conveyor belt connected to the conveying roller; wherein the conveying roller rotates in opposite directions to the picking roller, so that the conveying direction of the elastic conveyor belt close to the picking roller side is consistent with the direction in which the spring teeth convey the forage into a baler connected to the picking assembly.

[0006] Furthermore, the distance between the conveying rollers on both sides of the connecting frame and the pick-up roller is smaller than the distance between the conveying roller in the middle and the pick-up roller, so that the elastic conveyor belt is closer to the pick-up roller.

[0007] A semi-closed contoured grass pressing cavity is formed between the picking rollers.

[0008] Furthermore, the connecting frame is rotatably connected to the bracket at one end facing the molding chamber, the middle part of the connecting frame overlaps with the connecting piece, and the bracket has a supporting piece for overlapping with the connecting frame.

[0009] Furthermore, at least one of the three conveying rollers is dynamically connected to the pickup roller.

[0010] Furthermore, at least one of the conveying rollers is connected to the pickup roller via a first belt, and the middle portion of the first belt is arranged in a cross shape.

[0011] Furthermore, a roller is rotatably connected to the bracket at a position where the first belt crosses, and two sides of the roller are in rolling contact with the first belt respectively.

[0012] Furthermore, the connecting frame is also provided with a safety chain.

[0013] Furthermore, a split conveying mechanism is fixed on the connecting frame, and the split conveying mechanism includes a fixing frame, and the fixing frame is detachably connected to the connecting frame, and the fixing frame also includes:

[0014] comb plates, the comb plates being arranged at equal intervals toward the pick-up roller;

[0015] A rotating wheel, the rotating wheel is rotatably connected to the comb plate;

[0016] A grass belt roller, the grass belt roller is rotatably connected to one end of the fixing frame away from the comb plate;

[0017] The grass conveyor belt has a plurality of grass conveyor belts, and all of them are connected between the grass conveyor belt roller and the rotating wheel.

[0018] The upper surface of the grass conveying belt rotates toward the forming chamber.

[0019] Furthermore, the spacing between the comb plates is matched with the spacing of the spring teeth so that the spring teeth can pass through the comb plates.

[0020] Furthermore, the grass belt roller is dynamically connected to the pick-up roller.

[0021] The utility model discloses a baler, comprising a forage picking structure as described in any one of the above items.

[0022] The forage picking structure and baler provided by the utility model can achieve the following technical effects:

[0023] 1. When the grass falls forward under the action of centrifugal force, the utility model arranges a grass pressing assembly at the front upper part of the picking assembly, so that the elastic conveyor belt on the grass pressing assembly cooperates with the spring teeth on the picking assembly to block the grass falling forward and transport the grass backward, thereby improving the picking rate and transportation efficiency of the grass.

[0024] 2. Through the setting of the split conveying mechanism, the grass can be actively conveyed to the forming chamber after the spring teeth are moved, avoiding the grass choking phenomenon caused by the resistance caused by the sliding of the grass on the bracket.

[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other.

[0041] like Figures 1 to 6 As shown, the grass picking structure includes a picking component 1 and a grass pressing component 2. Figure 1 As shown in the figure, the pickup assembly 1 includes a bracket 11, a pickup roller 12 rotatably connected to the bracket 11, and spring teeth 13 arranged in a row and evenly distributed along the circumferential direction on the pickup roller 12; the spring teeth 13 have a certain elasticity, and the pickup roller 12 rotates under the drive of an external force. Figure 1 In some embodiments of the present invention, the pick-up roller 12 rotates clockwise to pick up the grass on the ground in the upper left direction.

[0042] like Figure 1As shown, the grass pressing assembly 2 is arranged above and in front of the direction in which the spring teeth 13 pick up grass, and includes a connecting frame 21, at least three conveying rollers 22 rotatably arranged on the connecting frame 21, and an elastic conveying belt 23 connected to the conveying rollers 22. Figure 1 As shown in the figure, the conveying roller 22 rotates in the opposite direction to the pick-up roller 12, so that the conveying direction of the elastic conveyor belt 23 near the pick-up roller 12 is consistent with the direction in which the spring teeth 13 convey the grass to the baler connected to the pick-up assembly 1. It should be pointed out here that the baler is a prior art, and has a molding chamber inside. The pick-up assembly 1 finally conveys the grass to the molding chamber of the baler for bale molding. In the embodiment of the utility model, the conveying roller 22 has power, and the lower surface of the elastic conveyor belt 23 is driven to move backward by the rotation of the conveying roller 22. The molding chamber (not shown in the figure) is set on the right side of the bracket 11. In this way, when the pick-up roller 12 rotates, the grass is conveyed toward the molding chamber, and the grass that rushes forward due to centrifugal force will be blocked by the elastic conveyor belt 23 and driven by the driving force of the elastic conveyor belt 23. The grass that rushes forward is also moved to the top of the pick-up roller 12 and then enters the molding chamber synchronously.

[0043] In the above embodiment, when the grass falls forward under the action of centrifugal force, the utility model arranges the grass pressing component 2 at the upper front of the picking component 1, so that the elastic conveyor belt 23 on the grass pressing component 2 cooperates with the spring teeth 13 on the picking component 1 to block the grass falling forward and transport it backward, thereby improving the picking rate and transportation efficiency of the grass.

[0044] Optionally, in order to further avoid the accumulation of grass, the distance between the conveying rollers 22 on both sides of the connecting frame 21 and the picking roller 12 is smaller than the distance between the conveying rollers 22 in the middle and the picking roller 12, so that a semi-enclosed contoured grass pressing chamber is formed between the elastic conveyor belt 23 and the picking roller 12. Figure 2 As shown in the figure, the elastic conveyor belt 23 has a certain elasticity. When the grass is accumulated between the picking roller 12 and the elastic conveyor belt 23, the elastic conveyor belt 23 deforms upward to expand the space for the grass to pass through, and when the elastic conveyor belt 23 is squeezed, the friction between it and the grass also increases, thereby further increasing the friction between it and the grass, so that the grass can be conveyed to the rear molding room as soon as possible.

[0045] Alternatively, if Figure 1As shown in the figure, the connecting frame 21 is rotatably connected to the bracket 11 at one end facing the molding chamber, the middle part of the connecting frame 21 overlaps with the connecting member, and the bracket 11 has a supporting member for overlapping with the connecting frame 21. Through this overlapping form, the pressure of the connecting frame 21 and the conveying roller 22 is used to increase the pressure when contacting with the forage, and when there is too much forage, the connecting frame 21 can be lifted to a certain distance, thereby protecting the elastic conveyor belt 23. In addition, in the embodiment of the utility model, the connecting frame 21 is also provided with a safety chain 24. By connecting with the agricultural machine through the safety chain 24, damage to the bracket 11 is avoided when the connecting frame 21 suddenly falls.

[0046] In the embodiment of the utility model, in order to reduce the space occupied by the picking device and save power resources, as Figure 3 and Figure 4 As shown in , one of the conveyor rollers 22 is connected to the pickup roller 12 by power. Specifically, in the embodiment of the utility model, one of the conveyor rollers 22 is connected to the pickup roller 12 via a first belt 25, and the middle of the first belt is a cross structure. Of course, it should be pointed out here that in some embodiments of the utility model, at least three conveyor rollers 22 are provided, and those skilled in the art can provide more as needed, and can also apply power to more conveyor rollers 22. In addition, in order to avoid belt damage caused by friction at the intersection of the first belt 25, as shown in FIG. Figure 4 As shown in FIG, the bracket 11 is also rotatably connected to a roller 26 at the intersection of the first belt 25, and both sides of the roller 26 are respectively in rolling contact with the first belt 25. In this way, when the belt drives the conveying roller 22 to rotate, both sides of the roller 26 are respectively in rolling contact with the belts on both sides, avoiding friction between the belts and improving

[0047] The service life of the belt.

[0048] Optionally, see Figure 3 Figure 5 and Figure 6 The connecting frame 21 is also fixed with a split conveying mechanism 3, which includes a fixed frame 31 detachably connected to the connecting frame 21, and the fixed frame 31 has comb plates 32 arranged at equal intervals toward the pick-up roller 12, a rotating wheel 33 rotatably connected to the comb plates 32, a grass belt roller 34 rotatably connected to the end of the fixed frame 31 away from the comb plates 32, and a plurality of grass conveying belts 35 connected between the grass belt roller 34 and the rotating wheel 33, and the upper surface of the grass conveying belt 35 rotates toward the molding chamber. In this way, the rotation of the grass belt roller 34 drives the rotation of the plurality of grass conveying belts 35, so that the grass material transmitted from the pick-up roller 12 and the elastic conveyor belt 23 obtains power and continues to be conveyed toward the molding chamber, avoiding the grass choking phenomenon at the rear end.

[0049] Alternatively, if Figure 4As shown in the figure, the spacing between the comb plates 32 is matched with the spacing between the spring teeth 13, so that the spring teeth 13 pass through the comb plates 32. By setting it in this way, the power of the spring teeth 13 is connected more smoothly with the power of the grass conveying belt 35, which improves the uniformity of grass movement and further avoids grass choking. In addition, in the embodiment of the utility model, in order to further save power resources, the grass belt roller 34 is connected to the pick-up roller 12. Figure 4 As shown in the embodiment of the utility model, the second belt can be connected to the grass belt roller 34 to achieve power connection. By setting it in this way, only the rotation of the pickup roller 12 is driven to synchronously drive the rotation of the elastic conveyor belt 23 and the grass conveying belt 35, thereby improving the synchronization of picking up grass.

[0050] The utility model also discloses a baler, comprising the forage picking structure as described in any one of the above embodiments.

[0051] Application scenario of an exemplary embodiment:

[0052] like Figures 1 to 6 As shown, when picking up grass, the picking roller 12 picks up the grass by rotating, and the spring teeth 13 on the picking roller 12 pick up the grass, and then the grass passes through the middle part of the picking roller 12 and the elastic conveyor belt 23, and is synchronously transported backwards by the transmission of the elastic conveyor belt 23 and the rotation of the picking roller 12. Through such an arrangement, at the initial stage when the spring teeth 13 on the picking roller 12 push the grass, the centrifugal force of the grass makes it fall forward, but the grass is transported backwards due to the spacing of the conveyor belt, thereby improving the transportation efficiency of the grass. At the same time, when the amount of grass in the working environment is too large, the elastic conveyor belt 23 will be deformed, so that more grass will enter the hollow part of the contoured grass pressing cavity. Since the elastic conveyor belt 23 has a certain elasticity, it can increase the friction when being stretched. This arrangement is more conducive to the smooth transportation of grass without blockage. In addition, after the grass moves to the rear end, the grass conveyor belt 35 is rotated to further transport the grass to the molding chamber, avoiding the accumulation in the prior art, thereby reducing the occurrence of grass choking.
