Description

Technical Field

[0001] This utility model belongs to the field of pesticide spraying machine technology, and specifically refers to a pesticide spraying machine inlet pipe device. Background Technology

[0002] For example, Chinese Utility Model No. 202120349700.7 discloses a universal hose reel sprayer, which includes a frame; a hose take-up reel, mounted on the frame, on which a hose is wound; a hose take-up and discharge motor, mounted on the frame, for driving the hose take-up reel to rotate to take up or discharge the hose; a hose delivery pump, mounted on the frame and connected to the hose, for delivering liquid pesticide to the hose; and a mounting frame, located above the hose take-up reel; a guide head is rotatably mounted in the mounting frame, and the guide head has a guide channel for placing the hose; during operation, the hose is located in the guide channel, and the opening of the guide channel is oriented in different directions by rotating the guide head.

[0003] In reality, the medicine tube enters through a reciprocating slider located at the bottom of the guide head, and the reciprocating slider has an opening for the medicine tube to enter. During the tube insertion process, the position of the medicine tube will be slightly offset from the position of the reciprocating slider, causing the medicine tube to come into contact with and rub against the edge of the opening on the reciprocating slider, thus hindering the normal delivery of the medicine tube and potentially causing wear and damage to the medicine tube in severe cases. Summary of the Invention

[0004] The purpose of this invention is to provide an inlet device that effectively reduces wear on the medicine tube.

[0005] The purpose of this utility model is achieved as follows:

[0006] An inlet device for a pesticide sprayer includes:

[0007] Support, the support having an inlet; and

[0008] The guide seat has a guide channel connected to the inlet; the guide seat is provided with a plurality of rolling elements, which are used to contact the medicine tube located in the guide channel to guide it into the inlet.

[0009] Furthermore, the rolling element includes a first roller and a second roller, the guide channel is square, the first roller is provided in two and is respectively located on two opposite first sides of the guide seat, and the second roller is provided in two and is respectively located on two opposite second sides of the guide seat.

[0010] Furthermore, the first roller and the second roller are arranged in a staggered manner, one above the other.

[0011] Furthermore, the top of the first side is provided with a first mounting groove for mounting the first roller, and the second side is provided with a second mounting groove for mounting the second roller, with the first mounting groove and the second mounting groove being offset vertically.

[0012] Furthermore, the first roller is provided with a first rotating shaft, the first roller is located in the first mounting groove, and the two ends of the first rotating shaft are respectively rotatably connected to two second side surfaces;

[0013] The second roller is provided with a second rotating shaft, the second roller is located in the second mounting groove, and the two ends of the second rotating shaft are respectively rotatably connected to the two first side surfaces.

[0014] Furthermore, the bottom of the guide seat is provided with a support foot, and the support foot is provided with a fastener that is connected to the support seat.

[0015] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0016] Because the guide seat is surrounded by a first roller and a second roller, the rolling element can guide the medicine tube well regardless of which direction it rotates, thus making the medicine tube transport smoother and reducing the occurrence of medicine tube wear.

[0017] Because the first roller and the second roller are staggered vertically, the first roller and the second roller can be positioned as a whole within the guide seat. From the axial direction of the guide seat, the staggered structure allows the two first rollers and the two second rollers to be tightly wrapped together. This ensures that when the medicine tube enters the guide channel, the front and back of the medicine tube are always in contact with the rolling element and are confined by the rolling element in the center of the guide channel, preventing contact with the edge of the guide seat. This increases the guiding effect of the guide seat, making the medicine tube transport smoother and preventing wear. Attached Figure Description

[0024] The present invention will be further described below with reference to specific embodiments:

[0025] A sprayer inlet device includes a support 1 and a guide seat 2, such as Figure 1 As shown, the support 1 is square. The support 1 in this patent is used to be installed in the reciprocating screw of the sprayer. Therefore, the support 1 is provided with a corresponding connecting hole for installing the reciprocating screw. The center of the support 1 is provided with an inlet 11 for the medicine tube to pass through for delivery.

[0026] The guide seat 2 is fixed to the bottom of the support 1, combined with Figure 1 , 2 As shown, the bottom of the guide seat 2 is provided with a support leg 24, and a fastening hole 241 is provided on the support leg 24. The entire guide seat 2 is fixed to the support 1 by setting a fastener in the fastening hole 241. The upper part of the guide seat 2 is generally square, with the middle part being vertically continuous, forming a guide channel 21 that is opposite to and connected to the inlet 11. Several rolling elements are arranged around the guide seat 2. The rolling elements are used to contact the medicine tube located in the guide channel 21 to guide it into the inlet 11.

[0027] Combination Figure 2 , 3 As shown, the rolling element in this patent includes a first roller 3 and a second roller 4. Since the guide seat 2 in this patent is square, two first side surfaces 25 are formed on both sides of the guide seat 2, and two second side surfaces 26 are formed on the other two sides. The first side surfaces 25 and the second side surfaces 26 are connected in sequence to form the upper part of the guide seat 2.

[0028] In this embodiment, the first roller 3 and the second roller 4 are staggered vertically. See details. Figure 2 , 3 In this patent, the top of the first side 25 is provided with a first mounting groove 22 for mounting the first roller 3, and the first mounting groove 22 is open upward; the second side 26 is provided with a second mounting groove 23 for mounting the second roller 4, and the second mounting groove 23 is located near the support leg 24 and is directly carved into the second side 26.

[0029] The first roller 3 is provided with a first rotating shaft 31, and the second roller 4 is provided with a second rotating shaft 41. The manufacturer can install the first roller 3 in the first mounting groove 22 by providing rotating holes on the first side surface 25 on both sides of the first mounting groove 22, or install the second roller 4 in the second mounting groove 23 by providing rotating holes on the second side surface 26 on both sides of the second mounting groove 23.

[0030] However, in this embodiment, the first roller 3 and the second roller 4 are positioned biased towards the inner side of the guide seat 2, combined with Figure 2 , 4 As shown, when the first roller 3 is located in the first mounting groove 22, both ends of the first rotating shaft 31 are rotatably connected to the two second side surfaces 26 respectively. After the medicine tube enters the guide seat 2, it first contacts the first roller 3 and is guided into the guide seat 2 by the first roller 3. Then it contacts the second roller 4 and is further guided by the second roller 4. Since the guide seat 2 is ringed with the first roller 3 and the second roller 4, the rolling elements can effectively guide and transport the medicine tube regardless of which direction it rotates, thus making the medicine tube transport smoother and reducing the occurrence of medicine tube wear.

[0031] Since the first roller 3 and the second roller 4 are staggered vertically, when setting the first roller 3 and the second roller 4, the first roller 3 and the second roller 4 can be located entirely within the guide seat 2. From the axial direction of the guide seat 2, the staggered structure allows the two first rollers 3 and the two second rollers 4 to be very tightly wrapped together, so that when the medicine tube enters the guide channel 21, the medicine tube can always contact the rolling element from front to back and be limited by the rolling element in the center of the guide channel 21 without contacting the edge of the guide seat 2. This increases the guiding effect of the guide seat 2, making the medicine tube transport smoother and preventing wear.
