Description

Technical Field

[0001] The utility model belongs to the technical field of resource utilization of livestock and poultry breeding wastewater, and specifically relates to a water and fertilizer spraying machine with forward rotation. Background Art

[0002] At present, direct large-scale spraying is usually adopted for field irrigation with manure water. However, since adjacent crops are usually spaced a certain distance apart during planting, large-scale spraying of manure water will lead to waste of manure fertility in the gaps, and manure water will flow everywhere, affecting the environment, causing workers to step on manure water when working.

[0003] The utility model patent with application number CN202121852224.7 proposes a pressure-stabilizing and precise discharge mechanism for a deep-applying manure and water operation vehicle. The liquid manure and fertilizer in the tank are introduced into the injection mechanism through an injection pipe for injection, so that the manure and fertilizer can be injected at a fixed point at a certain distance, thus solving the above-mentioned problem.

[0004] However, in actual use, it was found that the vehicle had to be stopped each time the manure fertilizer was injected, resulting in a relatively low fertilization efficiency of the manure fertilizer. Utility Model Content

[0005] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a water-fertilizer spraying operation machine with forward rotation, which utilizes a driving mechanism to drive a swing frame to swing back and forth, so that the spray pipe forms a reciprocating swing, and the spray pipe is always facing the fertilizer pit during the swinging process, so that the operation machine can fertilize the spaced fertilizer pits while continuously moving forward, thereby improving the fertilization efficiency.

[0006] The specific technical solution adopted by the utility model is:

[0007] A water-fertilizer spraying machine with forward rotation comprises a work vehicle with a fertilizer storage tank, a spraying bracket and a spraying pipe, wherein the spraying bracket is fixedly connected to the work vehicle, the input end of the spraying pipe is connected to the fertilizer storage tank, and a swinging device is additionally provided, wherein the swinging device comprises a swinging frame, a transmission mechanism and a ground wheel, the swinging frame is hinged to the spraying bracket and has the freedom of swinging, the spraying pipe is fixedly connected to the swinging frame, the swinging frame is transmission-connected to the ground wheel by means of the transmission mechanism and swings with the movement of the work vehicle, and the spraying pipe swings by means of the swinging device.

[0008] The transmission mechanism includes a first gear and a second gear that are engaged with each other, the first gear and the second gear are respectively connected to the injection bracket and have the freedom of rotation, the second gear is connected to the ground wheel by transmission, the first gear is connected to the ground wheel by transmission with the help of the second gear, the second gear is provided with a tooth gap, the first gear is provided with a first connecting rod hinged to the swing frame, and the swing frame swings with the help of the first connecting rod.

[0009] The swing device also includes a reset spring, a fixed end of the reset spring is fixedly connected to the injection bracket, and a telescopic end of the reset spring is connected to the free end of the swing frame. The swing frame is reset by means of the reset spring and the first connecting rod drives the first gear to reset. The injection pipe forms a reciprocating swing with the help of the swing and reset of the swing frame.

[0010] The transmission mechanism also includes a third gear and a fourth gear. The third gear is coaxially arranged with the second gear, and the fourth gear is coaxially arranged with the ground wheel. The third gear and the fourth gear are engaged with each other, and the second gear is transmission-connected with the ground wheel by means of the third gear and the fourth gear.

[0011] The hinge point between the first gear and the first connecting rod, the hinge point between the swing frame and the first connecting rod, the hinge point between the first gear and the injection bracket, and the hinge point between the swing frame and the injection bracket jointly form a parallelogram.

[0012] The swing frame is arranged in two rows before and after the transmission mechanism. The swing frame located in front of the driving mechanism is connected to the driving mechanism by means of a first connecting rod, and the swing frame located behind the driving mechanism is connected to the driving mechanism by means of a second connecting rod. The first connecting rod and the second connecting rod are respectively at the same position of the hinge point with the first gear.

[0013] The spray pipes between the swing frames are arranged at intervals, and the spray pipes on the front and rear rows of swing frames are arranged in a cross-type manner.

[0014] The beneficial effects of the utility model are:

[0015] The utility model uses the transmission cooperation between the first gear, the second gear and the ground wheel to enable the first gear to rotate along with the travel of the working vehicle, and the first connecting rod is used to make the swing frame swing accordingly, and because the teeth of the second gear are provided with a smooth notch, when the tooth notch of the second gear rotates toward the first gear, the first gear cannot mesh with the second gear, and the swing frame is quickly reset by means of a reset spring, so that the injection direction of the injection pipe is rotated to be parallel to the initial injection direction, and the next fertilizer pit is sprayed. Since the swing frame has a slow swing speed when swinging by means of the first gear, and the direction of the injection pipe is always toward a shorter interval, thicker fertilizer will be sprayed in the shorter interval to form a fertilizer pit, and the swing frame is quickly reset and toward the next interval when swinging by means of the reset spring, and only a trace amount of fertilizer will be sprayed between the two intervals, so that a gap is formed between the two intervals. Through the above process, the working machine can fertilize the fertilizer pits in the interval while continuously moving forward, thereby improving the fertilization efficiency.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0021] Figure 3 In order to clearly show the structure of the second gear, some components of the ground wheel and the transmission mechanism are hidden.

[0022] Specific embodiments, such as Figure 1-3As shown, the utility model provides a water-fertilizer spraying machine with forward rotation, including a work vehicle 2 with a fertilizer storage tank 1, a spraying bracket 3 and a spraying pipe 4, the spraying bracket 3 is fixedly connected to the work vehicle 2, the input end of the spraying pipe 4 is connected to the fertilizer storage tank 1, and a swinging device is additionally provided, the swinging device includes a swinging frame 5, a transmission mechanism and a ground wheel 6, the swinging frame 5 is hinged to the spraying bracket 3 and has the freedom of swinging, the spraying pipe 4 is fixedly connected to the swinging frame 5, the swinging frame 5 is transmission-connected to the ground wheel 6 by means of the transmission mechanism and swings with the movement of the work vehicle 2, and the spraying pipe 4 swings by means of the swinging device.

[0023] Because the current water and fertilizer spraying vehicle 2 needs to stop and stand still each time the manure and fertilizer are injected in order to ensure that the manure and fertilizer can be injected at a fixed point at a certain distance during operation, the entire fertilization process is intermittent, resulting in a relatively low fertilization efficiency of the manure and fertilizer. Therefore, the utility model is provided with a swing device, which does not require stopping and standing still when spraying manure and fertilizer, and the vehicle is always in a forward state, which greatly improves the fertilization efficiency of manure and fertilizer. When the vehicle moves forward, the ground wheel 6 rotates synchronously with the vehicle, and the swing frame 5 is driven to swing by the rotation of the ground wheel 6 and the transmission of the transmission mechanism, so that the spray pipe 4 is always facing the fertilizer pit during the swinging process.

[0024] The swing frame 5 is provided with a through hole with a thread, the surface of the injection pipe 4 is provided with an external thread, the injection pipe 4 is threadedly connected to the swing frame 5, and the injection pipe 4 is connected to the fertilizer storage tank 1 by means of a liquid fertilizer pump.

[0025] like Figure 1-3As shown, the transmission mechanism includes a first gear 7 and a second gear 8 that are kneaded with each other. The first gear 7 and the second gear 8 are respectively connected to the injection bracket 3 and have the freedom of rotation. The second gear 8 is transmission-connected to the ground wheel 6. The first gear 7 is transmission-connected to the ground wheel 6 by means of the second gear 8. The second gear 8 is provided with a tooth gap. The first gear 7 is provided with a first connecting rod 9 hinged to the swing frame 5. The swing frame 5 swings by means of the first connecting rod 9, wherein the second gear 8 rotates in opposite directions to the ground wheel 6. When the vehicle moves forward, the ground wheel 6 rotates counterclockwise, the second gear 8 rotates clockwise, and the first gear 7 rotates counterclockwise. Since the first gear 7 is hinged to the swing frame 5 by means of the first connecting rod 9, the first gear 7 will drive the swing frame 5 to swing forward. At this time, the injection pipe 4 It swings synchronously with the swing frame 5; when the tooth gap of the second gear 8 rotates to face the first gear 7, at this time, since the surface of the second gear 8 is a smooth gap, the first gear 7 cannot mesh with the second gear 8, so the swing frame 5 and the injection pipe 4 quickly return to the initial position under the action of the reset spring 10, and the first gear 7 also returns to the initial position under the action of the first connecting rod 9. Since the swing frame 5 swings at a slow speed with the help of the first gear 7, the direction of the injection pipe 4 is always toward a shorter interval, and thicker fertilizer will be sprayed in the shorter interval to form a fertilizer pit, and the swing frame 5 quickly resets and faces the next interval when swinging with the help of the reset spring 10, and only a small amount of fertilizer will be sprayed between the two intervals, thereby forming a gap between the two intervals and improving the fertilization efficiency.

[0026] like Figure 1 and Figure 3 As shown, the swing device also includes a reset spring 10, the fixed end of the reset spring 10 is fixedly connected to the injection bracket 3, the telescopic end of the reset spring 10 is connected to the free end of the swing frame 5, the swing frame 5 is reset by means of the reset spring 10 and the first gear 7 is driven to reset by means of the first connecting rod 9, and the injection pipe 4 forms a reciprocating swing with the swing and reset of the swing frame 5. By setting the reset spring 10, when the tooth gap of the second gear 8 rotates to face the first gear 7, since the surface of the second gear 8 is a smooth gap, the first gear 7 cannot mesh with the second gear 8, resulting in the first gear 7 being unable to maintain the swing frame 5 to form a swing at this time, and the swing frame 5 and the injection pipe 4 quickly return to the initial position under the action of the reset spring 10, and the swing is formed in this cycle.

[0027] like Figure 2As shown, the transmission mechanism also includes a third gear 11 and a fourth gear 12. The third gear 11 is coaxially arranged with the second gear 8, and the fourth gear 12 is coaxially arranged with the ground wheel 6. The third gear 11 and the fourth gear 12 are kneaded, and the second gear 8 is connected to the ground wheel 6 by means of the third gear 11 and the fourth gear 12. In order to achieve that the second gear 8 rotates in opposite directions to the ground wheel 6, the utility model is further provided with a third gear 11 and a fourth gear 12. When the ground wheel 6 rotates counterclockwise as the working vehicle 2 moves forward, the fourth gear 12 is coaxially arranged with the ground wheel 6, and the fourth gear 12 also rotates counterclockwise, while the third gear 11 and the fourth gear 12 are kneaded, the third gear 11 rotates clockwise, and the second gear 8 is coaxially arranged with the third gear 11, so the second gear 8 also rotates clockwise, thereby achieving that the second gear 8 rotates in opposite directions to the ground wheel 6.

[0028] like Figure 3 As shown, the hinge point between the first gear 7 and the first connecting rod 9, the hinge point between the swing frame 5 and the first connecting rod 9, the hinge point between the first gear 7 and the injection bracket 3, and the hinge point between the swing frame 5 and the injection bracket 3 together form a parallelogram. The hinge point between the first gear 7 and the first connecting rod 9 is a, the hinge point between the first gear 7 and the injection bracket 3 is b, the hinge point between the swing frame 5 and the first connecting rod 9 is c, and the hinge point between the swing frame 5 and the injection bracket 3 is d. The first connecting rod 9 coincides with the straight line where the connecting lines a and c are located, and the first connecting rod 9 is parallel to the connecting lines b and d. Through the above geometric relationship, the rotation angle of the swing frame 5 can be always the same as the rotation angle of the first gear 7, so as to ensure that the swing frame 5 can form a reciprocating swing with the rotation and reset of the first gear 7.

[0029] like Figure 1 and Figure 3 As shown, the swing frame 5 is provided with two rows before and after the transmission mechanism, the swing frame 5 located in front of the driving mechanism is connected to the driving mechanism by means of the first connecting rod 9, and the swing frame 5 located behind the driving mechanism is connected to the driving mechanism by means of the second connecting rod 13, and the first connecting rod 9 and the second connecting rod 13 are respectively hinged at the same position with the first gear 7. Since the solid content of manure fertilizer is relatively high, the injection pipe 4 needs to be thicker to avoid clogging of the pipe mouth, but the thicker injection pipe 4 makes it impossible to fix more injection pipes 4 on one row of swing frames 5, so two rows of swing frames 5 are provided to fix more injection pipes 4, and at the same time, the two rows of swing frames 5 are respectively hinged to the first gear 7 by means of the first connecting rod 9 and the second connecting rod 13, so that the two rows of swing frames 5 only need one set of driving mechanism to drive, thereby reducing the mechanical cost.

[0030] The spray pipes 4 between the swing frames 5 are arranged at intervals, and the spray pipes 4 on the front and rear rows of swing frames 5 are arranged crosswise. When crops are planted densely, the crosswise arrangement of the spray pipes 4 can reduce the gap between each row of fertilizers to adapt to densely planted crops.
