[0038] In order for those skilled in the art to better understand the technical scheme of the utility model, the utility model will be further described in detail below in combination with the drawings.

[0039] Embodiment one:

[0040] Please refer to Figures 1-5 A knapsack type agricultural weeding and spraying device, comprising a knapsack type spraying box 1 and a shoulder strap 10, a pump body 2 is fixedly installed on one side of the knapsack type spraying box 1, a supporting plate 4 is fixedly installed on the other side of the knapsack type spraying box 1 opposite the pump body 2, a fixed box 6 is arranged on the top of the supporting plate 4, the end of the fixed box 6 is fixedly connected with the knapsack type spraying box 1, the fixed box 6 is located above the supporting plate 4, a fixed block 5 is fixedly installed on the inner wall of one side of the fixed box 6, a spray head assembly 3 is also installed on one side of the knapsack type spraying box 1, the spray head assembly 3 is located below the supporting plate 4, an adjusting assembly is installed above the supporting plate 4, and the adjusting assembly comprises a rotating mechanism 7, a moving mechanism 8 and a limiting assembly 9.

[0041] Specifically, the spray head assembly 3 is connected with the pump body 2 through a pipeline, so that the solution can flow smoothly, and the spraying angle and range can be adjusted according to actual needs, the moving mechanism 8 is driven to make mechanical swing by manually operating the rotating mechanism 7, so that the moving position of the spray head assembly 3 in the horizontal direction is consistent with the movement track of the moving mechanism 8, and mechanical swing of the spray head assembly 3 in the horizontal direction is realized.

[0042] The fixed block 5 is located on the inner wall of one side of the fixed box 6 close to the knapsack type spraying box 1.

[0043] Specifically, the fixed box 6 provides a stable support and protection platform for the fixed block 5 and the adjusting assembly, is used for protecting the adjusting assembly, so as to prevent the adjusting assembly from being damaged, makes the spray head assembly 3 maintain a stable state during use, and thus reduces the physical consumption of the operator.

[0044] The spray head assembly 3 comprises:

[0045] A hose 31, one end of the hose 31 penetrates through the side wall of the knapsack type spraying box 1 and is fixedly connected with the knapsack type spraying box 1, and the other end of the hose 31 is fixedly connected with a connecting pipe 35;

[0046] A hard pipe 32, which is fixedly installed at one end of the connecting pipe 35 away from the hose 31;

[0047] A nozzle 33, which is fixedly installed at one end of the hard pipe 32 away from the hose 31;

[0048] A switch 34, which is fixedly installed at one end of the hard pipe 32 close to the nozzle 33.

[0049] The hard pipe 32 is fixedly connected with the soft pipe 31 through a special connecting head or a threaded connecting piece, so that the connection between the soft pipe 31 and the hard pipe 32 is tight and reliable, and liquid leakage is avoided.

[0050] The rotating mechanism 7 comprises:

[0051] An eccentric wheel 71 is rotatably installed at one end of the fixed block 5 and located inside the fixed box 6;

[0052] A rotating shaft one 72 is rotatably installed at the other end of the eccentric wheel 71;

[0053] A connecting rod 74 is rotatably connected to the outer side wall of the rotating shaft one 72 at one end;

[0054] A rotating disc one 73 is rotatably installed at the top end of the rotating shaft one 72 and located above the fixed box 6;

[0055] A curved arm 75 penetrates the connecting rod 74 away from the rotating disc one 73 and is rotatably connected to the penetrating position of the connecting rod 74;

[0056] A single shaft 76 is fixedly installed at the top of the support plate 4;

[0057] A rotating disc two 77 is rotatably installed at the outer side of the single shaft 76 and located below the curved arm 75.

[0058] When the rotating disc one 73 is manually rotated, the eccentric wheel 71 performs local circumferential motion around the small rotating shaft, so that the rotation is transmitted to the connecting rod 74 through the rotating shaft one 72, the connecting rod 74 swings, the curved arm 75 also swings correspondingly, the rotating disc two 77 rotates, and the moving mechanism 8 is driven.

[0059] The moving mechanism 8 comprises:

[0060] A moving rod 81 is rotatably installed at the outer side of the single shaft 76 and located below the rotating disc two 77, and a sliding groove is formed at one end of the moving rod 81 close to the single shaft 76;

[0061] A sliding block 82 is slidably installed in the sliding groove of the moving rod 81;

[0062] The bottom end of the single shaft 76 penetrates the curved arm 75, the rotating disc two 77, the sliding block 82 and the moving rod 81 in sequence;

[0063] A vertical rod 83 is fixedly installed at one end of the bottom of the moving rod 81 and fixedly connected to one end of the connecting pipe 35 close to the soft pipe 31 through a bolt two, and a plurality of limiting grooves are formed in the vertical rod 83.

[0064] Specifically, the moving rod 81 is rotatably installed outside the single shaft 76 and below the rotating disc 77. The moving rod 81 can swing with the rotation of the single shaft 76. With the swinging of the moving rod 81, the sliding block 82 slides in the sliding groove, so that the position of the nozzle assembly 3 connected to the lower end of the vertical rod 83 swings synchronously with the swinging of the moving rod 81, thereby reducing the excessive muscle fatigue and physical consumption of the operator caused by the back-and-forth swinging of the wrist.

[0065] The limiting assembly 9 comprises:

[0066] The base 91 is fixedly installed at one end of the connecting pipe 35 close to the hard pipe 32. One side of the base 91 is hingedly connected with the hinge one 92.

[0067] The hinge two 93 is hingedly connected at the other side of the base 91. A circular hole is formed in the end of the hinge two 93 close to the vertical rod 83.

[0068] The latch 94 is clamped to the inner wall of the circular hole of the hinge two 93 and longitudinally penetrates the circular hole. The end of the latch 94 close to the hinge one 92 is fixedly connected with the spring 95. The other end of the spring 95 is fixedly connected to the side of the hinge one 92 close to the hinge two 93.

[0069] Specifically, when the spraying angle of the nozzle assembly 3 needs to be adjusted, the latch 94 is first pulled out to make the spring 95 deform, so that the latch 94 can move along the limiting slot formed in the vertical rod 83 to the desired position. Then the latch 94 is released to reset, thereby limiting the nozzle assembly 3 and driving the hinge one 92 and the hinge two 93 to move, so as to change the spraying angle of the nozzle assembly 3.

[0070] Embodiment two:

[0071] Please refer to Figure 4 The embodiment provides a technical scheme based on the embodiment one.

[0072] The latch 94 and the spring 95 in the limiting assembly 9 can also be provided as a fixed pin. When the spraying angle of the nozzle assembly 3 needs to be changed, the fixed pin can be pulled out or pressed to adjust and achieve stable locking effect.

[0073] Working principle: when in use, after the knapsack type spraying box 1 is worn on the body, the angle of the nozzle assembly 3 is adjusted through the limiting assembly 9 to ensure that the height of the sprayed liquid is adapted to the height of the crops. Then the pump body 2 is started, and the rotating disc one 73 is manually operated to rotate and drive the rotating mechanism 7 to move, so that the moving mechanism 8 makes mechanical swinging, thereby making the moving position of the nozzle assembly 3 in the horizontal direction consistent with the movement track of the moving mechanism 8. The weeds are sprayed back and forth, and the use of the adjusting assembly can reduce the number of back-and-forth swinging of the wrist and arm of the operator, reduce the force required for operation to reduce physical consumption, and improve the working efficiency of the operator.

[0074] Certain exemplary embodiments of this application are described herein by way of illustration. It should be understood that to those skilled in the art, upon consideration of this disclosure, various modifications could be practiced without departing from the spirit and scope of the application. Thus, the foregoing description is by way of example only, and is not intended to be limiting.
