Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and in particular relates to a device for adjusting the harvesting depth of a water chestnut harvester. Background Art

[0002] Water chestnut, also known as water chestnut, is rich in nutritional value and has a crisp taste. It is grown in most parts of southern my country and is usually harvested manually or using a water chestnut harvester.

[0003] When using a harvester for harvesting, the harvesting depth of the harvester needs to be adjusted, which is usually set before harvesting. It is difficult to make real-time adjustments during the harvesting process. Once the harvesting depth of the water chestnut harvester changes, it is easy to cause damage to the water chestnuts, affecting the harvesting efficiency of the water chestnuts.

[0007] Two side-by-side fixing plates, the two fixing plates are fixedly mounted on the bottom of the front end of the water chestnut harvester;

[0008] an adjustment plate hinged to both fixed plates; and

[0009] Two telescopic parts are arranged on the adjusting plate and are used to change the angle between the adjusting plate and the fixing plate so as to change the harvesting depth of the water chestnut harvester.

[0010] Preferably, the telescopic member adopts an electric push rod or a hydraulic cylinder.

[0011] Preferably, the telescopic member is rotatably mounted on the water chestnut harvester.

[0013] Preferably, the angle between the adjusting plate and the fixing plate is 30-45°.

[0014] Preferably, the adjustment plate comprises a first section and a second section, and an end of the second section away from the first section extends toward the fixing plate.

[0015] Preferably, the length of the first section is greater than the length of the second section.

[0016] Preferably, the adjustment device further includes a laser ranging sensor and a controller, wherein the laser ranging sensor is used to obtain the height value between the water chestnut harvester and the ground, and the controller is used to control the extension and retraction of the telescopic member according to the height value.

[0017] The beneficial effects of the utility model are:

[0018] The utility model detects the harvesting depth of the water chestnut harvester by means of a sensor, and when the harvesting depth of the water chestnut harvester deviates too much from the set value, the controller automatically controls the adjustment plate to control the harvesting angle of the water chestnut harvester, thereby directly adjusting the harvesting depth of the water chestnut harvester, so that the water chestnut harvester harvests the water chestnuts at a correct height, thereby avoiding damage to the soil layer and the water chestnuts.

[0023] The present application is described in further detail below. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example 1

[0025] like Figure 1-3 As shown, a device for adjusting the harvesting depth of a water chestnut harvester includes two side-by-side fixing plates 1, which are fixedly mounted on the bottom of the water chestnut harvester. A fixing plate 1 can be mounted on both sides of the bottom of the water chestnut harvester to achieve a balanced and symmetrical effect. The width of the fixing plate 1 is preferably 20 cm.

[0026] An adjustment plate 2 is hingedly provided at one end of the fixed plate 1 located in the forward direction of the water chestnut harvester, and the adjustment plate 2 is hinged to both fixed plates 1. The adjustment plate 2 is located below the fixed plate 1, and the angle between the adjustment plate 2 and the fixed plate 1 is preferably 30°. The adjustment plate 2 extends in the opposite direction of the forward direction of the water chestnut harvester. When the water chestnut harvester moves, the bottom surface of the adjustment plate 2 contacts the ground, and the harvesting depth of the water chestnut harvester can be controlled.

[0027] The non-telescopic ends of the two telescopic members 3 are rotatably mounted on the water chestnut harvester, and the telescopic members 3 are electric push rods or hydraulic cylinders.

[0028] The telescopic member 3 is connected to a controller, and the controller is connected to a laser distance measuring sensor. The controller adopts a small computer. The laser distance measuring sensor is fixedly installed at the front end of the water chestnut harvester, with the measuring direction facing the ground, and is used to measure the harvesting height of the water chestnut harvester.

[0029] The telescopic end of the telescopic member 3 is rotatably mounted on the adjusting plate 2 away from the end of the fixing plate 1 hinged with the adjusting plate 2 .

[0030] The adjustment plate 2 includes a first section 4 and a second section 5, and an end of the second section 5 away from the first section 4 extends toward the fixed plate 1. The angle between the second section 5 and the first section 4 is 150°.

[0031] The length of the first section 4 is greater than the length of the second section 5 .

[0032] It should be noted that when the water chestnut harvester is moving forward, the laser ranging sensor measures the harvesting depth of the water chestnut harvester (the distance between the laser ranging sensor and the ground) in real time. When the harvesting depth of the water chestnut harvester is greater than the set value, the data measured by the laser ranging sensor is abnormal, and the laser ranging sensor sends the data to the controller, which analyzes the signal and controls the extension of the telescopic member 3. When the telescopic member 3 is extended, the free end of the adjustment plate 2 is driven away from the fixed plate 1, thereby increasing the angle between the adjustment plate 2 and the fixed plate 1. The inclination of the first section 4 increases during the downward opening of the adjustment plate 2. The first section 4 lifts the harvester during contact with the ground, thereby changing the harvesting angle of the water chestnut harvester, thereby changing the harvesting depth of the water chestnut harvester.

[0033] After harvesting is completed, the telescopic member 3 drives the adjusting plate 2 to approach the fixed plate 1, so that the adjusting plate 2 is away from the ground and does not affect the normal movement of the water chestnut harvester.

[0034] When the harvesting depth of the harvester is less than the set value, the adjustment method of the telescopic member 3 is opposite to the above method.

[0035] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
