Description

Technical Field

[0001] The utility model relates to the technical field of smearing devices, in particular to a herbicide smearing device. Background Art

[0002] Herbicides, also known as weed killers, are agents that kill weeds completely or selectively. They are substances used to eliminate or inhibit plant growth. Examples include sodium chlorate, borax, arsenic salts, and trichloroacetic acid, which kill all plant species. Their effectiveness is influenced by the herbicide, the plant, and environmental conditions. Herbicides are categorized as either total or selective. Selective herbicides, particularly nitrophenol, chlorophenol, and carbamic acid derivatives, are generally effective. Global herbicide development is stabilizing, with the focus on high-efficiency, low-toxicity, broad-spectrum, and low-use-rate products. Disposable treatments with minimal environmental pollution are becoming the mainstream. Organic compounds are commonly used to control weeds, shrubs, trees, and other harmful plants in farmland, orchards, flower nurseries, grasslands, non-arable land, railway lines, rivers, reservoirs, warehouses, and other areas.

[0003] When applying herbicides to weeds, the herbicides are applied to the weeds through multiple rollers, so that the weeds can be removed individually and in a targeted manner, thereby reducing damage to crops. However, the distance between the multiple rollers is generally fixed. Different types of weeds may exist in different fields, such as purslane, foxtail grass, and goosegrass. These weeds not only have different heights but also different sizes. This makes it difficult to evenly apply the herbicides to different types of weeds using the roller application method, resulting in insufficient herbicide efficacy and the possibility of failing to kill the weeds. Therefore, a herbicide application device is proposed. Utility Model Content

[0027] Example

[0028] Reference Figures 1-4 , is an embodiment of the present utility model, which provides a herbicide application device, including: a driving unit 100 and an application unit 200;

[0029] Among them, the driving unit 100 includes a trolley 101 and a door-shaped plate 102 slidably arranged on the top of the trolley 101, a servo motor 103 is fixedly installed on the top of the inner wall of the door-shaped plate 102, and the output end of the servo motor 103 is fixedly connected to the driving pulley 104, and two I-shaped plates 105 are slidably provided on the top of the trolley 101. The tops of the two I-shaped plates 105 are rotatably connected to driven pulleys 106, and transmission belts 107 are respectively connected to the two driven pulleys 106 and the driving pulleys 104. The two sides of the door-shaped plate 102 are respectively hinged to the two I-shaped plates 105 with connecting plates 108, and the bottom of the trolley 101 is fixedly connected to a fixed plate 109, and one side of the fixed plate 109 is rotatably connected to a positive and negative threaded rod 110 that passes through the fixed plate 109, and the two I-shaped plates 105 are respectively threadedly sleeved on the two ends of the positive and negative threaded rod 110;

[0030] The smearing unit 200 includes a liquid storage tank 201 fixedly connected to the top of the cart 101, and the bottoms of the two I-shaped plates 105 are fixedly connected to an annular box 202. The inner walls of the two annular boxes 202 are provided with multiple spray holes. A hose 203 is fixedly connected between the liquid storage tank 201 and the two annular boxes 202. The bottom ends of the two active pulleys 104 are fixedly connected to a rotating rod 204 that passes through the corresponding I-shaped plate 105, and the rod surfaces of the two rotating rods 204 are fixedly sleeved with a sponge cover 205.

[0031] The top of the cart 101 is provided with a long strip opening for sliding two I-shaped plates 105. The two I-shaped plates 105 are symmetrically distributed on the opposite threads at both ends of the forward and reverse screw rods 110. When the forward and reverse screw rods 110 are rotated, the two I-shaped plates 105 can move closer to or farther away from each other, thereby adjusting the distance between the two I-shaped plates 105 according to the size of different weeds, so as to facilitate the application of herbicides to weeds of different sizes. When the servo motor 103 drives the active pulley 104 to rotate, the active pulley 104 can drive the two driven belts through the two transmission belts 107. As the pulley 106 rotates, when the two I-plates 105 move away from each other, the two I-plates 105 pull the gate plate 102 through the connecting plate 108 to move the gate plate 102 toward the liquid storage tank 201, thereby keeping the relative distance between the driving pulley 104 and the driven pulley 106 constant. When the two I-plates 105 move toward each other, the gate plate 102 moves away from the liquid storage tank 201 through the connecting plate 108, and the relative distance between the driving pulley 104 and the two driven pulleys 106 remains constant.

[0032] In this way, when the spacing between the two I-plates 105 is adjusted, the servo motor 103 can always drive the two driven pulleys 106 to rotate. A sealing cover is provided on the top of the liquid storage tank 201. The sealing cover can be opened to add herbicide into the liquid storage tank 201. A water pump is provided in the liquid storage tank 201, and the herbicide in the liquid storage tank 201 can be transported to the two hoses 203 through the water pump. The herbicide then enters the annular box 202 through the hoses 203, and the herbicide in the two annular boxes 202 is then sprayed onto the two sponge sleeves 205 through their respective spray holes. When the two driven pulleys 106 drive the two rotating rods 204 to rotate, the two rotating rods 204 drive the two sponge sleeves 205 that have absorbed the herbicide to rotate, and the weeds pass through the two sponge sleeves 205, and the herbicide is applied to the weeds through the two sponge sleeves 205, thereby achieving the effect of weeding.

[0033] In addition, a cylindrical groove is formed at the bottom end of the rotating rod 204 , a plurality of rectangular openings are formed at the bottom of the side wall of the rotating rod 204 , and a collecting bucket 206 is threadedly sleeved on the bottom end of the rotating rod 204 .

[0034] When the herbicide is sprayed onto the rotating rod 204 through the annular box 202, the herbicide on the rotating rod 204 is adsorbed on the top of the sponge sleeve 205 until the sponge sleeve 205 is completely soaked with the herbicide and then the weeds are smeared. When the smearing is completed, the herbicide remaining on the sponge sleeve 205 will flow downward to the bottom of the sponge sleeve 205 under the action of gravity. Each rectangular opening is connected to the cylindrical groove. The excess herbicide flows into the cylindrical groove through the rectangular opening and finally flows into the collection bucket 206. The collection bucket 206 can be rotated and removed from the rotating rod 204. The collection bucket 206 can prevent the remaining herbicide from dripping everywhere, thereby reducing pollution to the environment. After recycling, the collection bucket 206 is re-rotated and installed on the bottom of the rotating rod 204.

[0035] Furthermore, the rod surface of the rotating rod 204 is fixedly sleeved with a conical cover 207, the bottom end of the inner wall of the conical cover 207 is flush with the bottom of the rectangular opening, and the side walls of the two annular boxes 202 are fixedly connected with arc plates 208, and the two arc plates 208 are symmetrically distributed.

[0036] The diameter of the conical cover 207 decreases from top to bottom, the bottom end of the conical cover 207 is sealed against the side wall of the rotating rod 204, and the lowest point of the conical cover 207 is located at the bottom of the rectangular opening, while the lowest point of the inner wall of the conical cover 207 is flush with the bottom of the rectangular opening. The conical cover 207 can guide the herbicide that has not entered the cylindrical groove, so that the herbicide on the outer wall of the rotating rod 204 flows back into the collection barrel 206 through the rectangular opening, and the two curved plates 208 can be used to block the two sides of the cart 101, so that the sponge cover 205 will not throw the herbicide to the two sides of the cart 101 during rotation.

[0037] Furthermore, one side of the two I-shaped plates 105 is fixedly connected to a limit plate 209, and the two hoses 203 slide through the two limit plates 209 respectively. The bottom of the cart 101 is fixedly connected to two V-shaped plates 210, and a baffle 211 is fixedly connected between the two V-shaped plates 210.

[0038] The two limiting plates 209 can move synchronously with the two I-shaped plates 105. The two limiting plates 209 respectively limit the two hoses 203. When the two I-shaped plates 105 move away from each other, the hoses 203 are stretched. When the two I-shaped plates 105 move closer to each other, the hoses 203 are no longer stretched, and the excess length of the hoses 203 naturally droops. The two limiting plates 209 can limit the hoses 203 so that the hoses 203 do not sag excessively, thereby preventing the hoses 203 from being entangled in overly tall weeds.

[0039] Two handles are fixedly connected to the top of the cart 101 for workers to push the cart 101. Two V-shaped plates 210 are located below the two handles. A gap is left between the two V-shaped plates 210 to facilitate weeds to pass through the gap between the two V-shaped plates 210. The two V-shaped plates 210 can protect the legs of the workers, so that the V-shaped plates 210 can guide the weeds sprayed with herbicides to avoid direct contact between the legs and the weeds, thereby reducing the harm of the herbicide to the legs. The weeds sprayed with herbicides can be pressed down by the baffle 211 to prevent the weeds from being squeezed by the V-shaped plates 210 and then throwing the herbicide onto the workers due to their own toughness. The baffle 211 and the V-shaped plates 210 are used to protect the workers.

[0040] During use, the forward and reverse screw rods 110 are rotated according to the size of the weeds to adjust the distance between the two I-plates 105. After the adjustment is completed, herbicide is added to the liquid storage tank 201, and then the servo motor 103 is started to drive the active pulley 104 to rotate. The active pulley 104 can drive the two driven pulleys 106 to rotate through the two transmission belts 107. Then, the water pump built into the liquid storage tank 201 is started to transport the herbicide in the liquid storage tank 201 to the two hoses 203. , then the herbicide enters the annular box 202 through the hose 203, and then the herbicide in the two annular boxes 202 is sprayed onto the two sponge sleeves 205 through their respective spray holes. When the two driven pulleys 106 drive the two rotating rods 204 to rotate, the two rotating rods 204 drive the two sponge sleeves 205 adsorbed with the herbicide to rotate, and the herbicide is applied to the weeds through the two sponge sleeves 205, and then the cart 101 is pushed to move, so as to apply the herbicide to the weeds in the field;

[0041] After the application is completed, the herbicide remaining on the sponge sleeve 205 will flow downward to the bottom of the sponge sleeve 205 under the action of gravity, and the excess herbicide will flow into the circular groove through the rectangular opening and finally flow into the collection bucket 206. The collection bucket 206 can be rotated and removed from the rotating rod 204. The collection bucket 206 can prevent the remaining herbicide from dripping everywhere, thereby reducing pollution to the environment. After the recycling is completed, the collection bucket 206 is rotated and reinstalled on the bottom of the rotating rod 204.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
